European bison

The European bison (: bison) (Bison bonasus) or the European wood bison, also known as the wisent ( or ), the zubr, or sometimes colloquially as the European buffalo, is a European species of bison. It is one of two extant species of bison, alongside the American bison. The European bison is the heaviest wild land animal in Europe, and individuals in the past may have been even larger than their modern-day descendants. During late antiquity and the Middle Ages, bison became extinct in much of Europe and Asia, surviving into the 20th century only in northern-central Europe and the northern Caucasus Mountains. During the early years of the 20th century, bison were hunted to extinction in the wild.

By the late 2010s, the species numbered several thousand and had been returned to the wild by captive breeding programmes. It is no longer in immediate danger of extinction, but remains absent from most of its historical range. It is not to be confused with the aurochs (Bos primigenius), the extinct ancestor of domestic cattle, with which it once co-existed.

Besides humans, bison have few predators. In the 19th century, there were scattered reports of wolves, lions,  tigers, and bears hunting bison. In the past, especially during the Middle Ages, humans commonly killed bison for their hide and meat. They used their horns to make drinking horns.

European bison were hunted to extinction in the wild in the early 20th century, with the last wild animals of the B. b. bonasus subspecies being shot in the Białowieża Forest (on today's Belarus–Poland border) in 1921. The last of the Caucasian wisent subspecies (B. b. caucasicus) was shot in the northwestern Caucasus in 1927. The Carpathian wisent (B. b. hungarorum) had been hunted to extinction by 1852.

The Białowieża or lowland European bison was kept alive in captivity, and has since been reintroduced into several countries in Europe. In 1996, the International Union for Conservation of Nature classified the European bison as an endangered species, no longer extinct in the wild. Its status has improved since then, changing to vulnerable and later to near-threatened.

European bison were first scientifically described by Carl Linnaeus in 1758. Some later descriptions treat the European bison as conspecific with the American bison. Three subspecies of the European bison existed in the recent past, but only one, the nominate subspecies (B. b. bonasus), survives today. The ancestry and relationships of the wisent to fossil bison species remain controversial and disputed.

The European bison is one of the national animals of Poland and Belarus.

Etymology
The ancient Greeks and ancient Romans were the first to name bison as such; the 2nd-century AD authors Pausanias and Oppian referred to them as. Earlier, in the 4th century BC, during the Hellenistic period, Aristotle referred to bison as. He also noted that the Paeonians called it μόναπος (monapos). Claudius Aelianus, writing in the late 2nd or early 3rd centuries AD, also referred to the species as, and both Pliny the Elder's Natural History and Gaius Julius Solinus used bĭson and bonāsus. Both Martial and Seneca the Younger mention bison (pl. bisontes). Later Latin spellings of the term included visontes, vesontes, and bissontes.

John Trevisa is the earliest author cited by the Oxford English Dictionary as using, in his 1398 translation of Bartholomeus Anglicus's De proprietatibus rerum, the Latin plural bisontes in English, as "bysontes" (byſontes and bysountes). Philemon Holland's 1601 translation of Pliny's Natural History, referred to "bisontes". The marginalia of the King James Version gives "bison" as a gloss for the Biblical animal called the "pygarg" mentioned in the Book of Deuteronomy. Randle Cotgrave's 1611 French–English dictionary notes that bison was already in use, and it may have influenced the adoption of the word into English, or alternatively it may have been borrowed direct from Latin. John Minsheu's 1617 lexicon, Ductor in linguas, gives a definition for Bíson ("a wilde oxe, great eied, broad-faced, that will neuer be tamed").

In the 18th century the name of the European animal was applied to the closely related American bison (initially in Latin in 1693, by John Ray) and the Indian bison (the gaur, Bos gaurus). Historically the word was also applied to Indian domestic cattle, the zebu (B. indicus or B. primigenius indicus). Because of the scarcity of the European bison the word 'bison' was most familiar in relation to the American species.

By the time of the adoption of 'bison' into Early Modern English, the early medieval English name for the species had long been obsolete: the had descended from *wisand, wisund and was related to vísundr. The word 'wisent' was then borrowed in the 19th century from modern Wisent [], itself related to wisunt, wisent, wisint, and to wisant, wisent, wisen, and ultimately, like the Old English name, from Proto-Germanic. The *wis-, also found in weasel, originally referred to the animal's musk.

The word 'zubr' in English is a borrowing from żubr, previously also used to denote one race of the European bison. The Polish żubr is similar to the word for the European bison in other modern Slavic languages, such as žubr and зубр. The noun for the European bison in all living Slavonic tongues is thought to be derived from Proto-Slavic: *zǫbrъ ~ *izǫbrъ, which itself possibly comes from Proto-Indo-European: *ǵómbʰ- for tooth, horn or peg.

Description
The European bison is the heaviest surviving wild land animal in Europe. Similar to their American cousins, European bison were potentially larger historically than remnant descendants; modern animals are about 2.8 to 3.3 m in length, not counting a tail of 30 to 92 cm, 1.8 to 2.1 m in height, and 615 to 920 kg in weight for males, and about 2.4 to 2.9 m in body length without tails, 1.69 to 1.97 m in height, and 424 to 633 kg in weight for females. At birth, calves are quite small, weighing between 15 and 35 kg. In the free-ranging population of the Białowieża Forest of Belarus and Poland, body masses among adults (aged 6 and over) are 634 kg on average in the cases of males, and 424 kg among females. An occasional big bull European bison can weigh up to 1000 kg or more with old bull records of 1900 kg for lowland wisent and 1000 kg for Caucasian wisent.

On average, it is lighter in body mass, and yet slightly taller at the shoulder, than its American relatives, the wood bison (Bison bison athabascae) and the plains bison (Bison bison bison). Compared to the American species, the wisent has shorter hair on the neck, head, and forequarters, but longer tail and horns. See differences from American bison.

The European bison makes a variety of vocalisations depending on its mood and behaviour, but when anxious, it emits a growl-like sound, known in Polish as chruczenie. This sound can also be heard from wisent males during the mating season.

Prehistory
The similar skeletal morphology of the wisent with the steppe bison (Bison priscus) which also formerly inhabited Europe complicates the understanding of the early evolution of the European bison. Genetic evidence indicates that European bison were present across Europe, from France to the Caucasus during the Last Glacial Period, where they co-existed alongside steppe bison. Late Pleistocene European bison belong to two mitochondrial lineages, which are estimated to have split over 400,000 years ago, Bb1 (also known as Bison X) and Bb2. Bb1 became extinct at the end of the Late Pleistocene, with all modern European bison belonging to the Bb2 lineage. At the end of the Last Glacial Period steppe bison became extinct in Europe, leaving European bison as the only bison species in the region. Historically, the lowland European bison's range encompassed most of the lowlands of northern Europe, extending from the Massif Central to the Volga River and the Caucasus. It may have once lived in the Asiatic part of what is now the Russian Federation, reaching to Lake Baikal and Altai Mountains in east. The European bison is known in southern Sweden only between 9500 and 8700 BP, and in Denmark similarly is documented only from the Pre-Boreal. It is not recorded from the British Isles, nor from Italy or the Iberian Peninsula, although prehistorical absence of the species among British Isles is debatable; bison fossils of unclarified species have been found on Doggerland or Brown Bank, and Isle of Wight and Oxfordshire, followed by fossil records of Pleistocene woodland bison and steppe bison from the isles. The extinct steppe bison (B. priscus) is known from across Eurasia and North America, last occurring 7,000 BC to 5,400 BC, and is depicted in the Cave of Altamira and Lascaux. The Pleistocene woodland bison (B. schoetensacki) has been proposed to have last existed around 36,000 BC. But other authors restrict B. schoetensacki to remains that are hundreds of thousands of years older. Cave paintings appear to distinguish between B. bonasus and B. priscus.

Antiquity and Middle Ages
Within mainland Europe, its range decreased as human populations expanded and cut down forests. They seemed to be common in Aristotle's period on Mount Mesapion (possibly the modern Ograzhden). In the same wider area Pausanias calling them Paeonian bulls and bison, gives details on how they were captured alive; adding also the fact that a golden Paeonian bull head was offered to Delphi by the Paeonian king Dropion (3rd century BC) who lived in what is today Tikveš. The last references (Oppian, Claudius Aelianus) to the animal in the transitional Mediterranean/Continental biogeographical region in the Balkans in the area of modern borderline between Greece, North Macedonia and Bulgaria date to the 3rd century AD. In northern Bulgaria, the wisent was thought to have survived until the 9th or 10th century AD, but more recent data summary shows that the species survived up to 13th - 14th century AD in eastern Bulgaria and up to 16th - 17th century AD in the northern part of the country. There is a possibility that the species' range extended to East Thrace during the 7th–8th century AD. Its population in Gaul was extinct in the 8th century AD. The species survived in the Ardennes and the Vosges Mountains until the 15th century. In the Early Middle Ages, the wisent apparently still occurred in the forest steppes east of the Urals, in the Altai Mountains, and seems to have reached Lake Baikal in the east. The northern boundary in the Holocene was probably around 60°N in Finland. European bison survived in a few natural forests in Europe, but their numbers dwindled.

Early Modern period
In 1513 the Białowieża Forest, at this point one of the last areas on Earth where the European bison still roamed free, was transferred from the Troki Voivodeship of Lithuania to the Podlaskie Voivodeship, which after the Union of Lublin became part of the Polish Crown. In the Polish–Lithuanian Commonwealth, at first European bison in the Białowieża Forest were legally the property of the Grand Dukes of Lithuania and later belonged to the Crown of the Kingdom of Poland. Polish-Lithuanian rulers took measures to protect the European bison, such as King Sigismund II Augustus who instituted the death penalty for poaching bison in Białowieża in the mid-16th century. Wild European bison herds existed in the forest until the mid-17th century. In 1701, King Augustus II the Strong greatly increased protection over the forest; the first written sources mentioning the use of some forest meadows for the production of winter fodder for the bison come from this period. In the early 19th century, after the partitions of the Polish Commonwealth, the Russian tsars retained old Polish-Lithuanian laws protecting the European bison herd in Białowieża. Despite these measures and others, the European bison population continued to decline over the following century, with only Białowieża and Northern Caucasus populations surviving into the 20th century. The last European bison in Transylvania died in 1790.

Early 20th century
During World War I, occupying German troops killed 600 of the European bison in the Białowieża Forest for sport, meat, hides and horns. A German scientist informed army officers that the European bison were facing imminent extinction, but at the very end of the war, retreating German soldiers shot all but nine animals. The last wild European bison in Poland was killed in 1921. The last wild European bison in the world was killed by poachers in 1927 in the western Caucasus. By that year, 48 remained, all held by zoos. The International Society for the Preservation of the Wisent was founded on 25 and 26 August 1923 in Berlin, following the example of the American Bison Society. The first chairman was Kurt Priemel, director of the Frankfurt Zoo, and among the members were experts like Hermann Pohle, Max Hilzheimer and Julius Riemer. The first goal of the society was to take stock of all living bison, in preparation for a breeding programme. Important members were the Polish Hunting Association and the Poznań zoological gardens, as well as a number of Polish private individuals, who provided funds to acquire the first bison cows and bulls. The breeding book was published in the company's annual report from 1932. While Priemel aimed to grow the population slowly with pure conservation of the breeding line, Lutz Heck planned to grow the population faster by cross-breeding with American bison in a separate breeding project in Munich, in 1934.

World War II
Heck gained the support of then Reichsjägermeister Hermann Göring, who hoped for huntable big game. Heck promised his powerful supporter in writing: "Since surplus bulls will soon be set, the hunting of the Wisent will be possible again in the foreseeable future". Göring himself took over the patronage of the German Professional Association of Wisent Breeders and Hegers, founded at Heck's suggestion. Kurt Priemel, who had since resigned as president of the International Society for the Preservation of the Wisent, warned in vain against "manification". Heck answered by announcing that Göring would take action against Priemel if he continued to oppose his crossing plans. Priemel was then banned from publishing in relation to bison breeding, and the regular bookkeeper of the International Society, Erna Mohr, was forced to hand over the official register in 1937. Thus, the older society was effectively incorporated into the newly created Professional Association. After the Second World War, therefore, only the pure-blooded bison in the game park Springe near Hanover were recognised as part of the international herd book.

1950s onwards
The first two bison were released into the wild in the Białowieża Forest in 1929. By 1964 more than 100 existed. Over the following decades, thanks to Polish and international efforts, the Białowieża Forest regained its position as the location with the world's largest population of European bison, including those in the wild. In 2005–2007, a wild bison nicknamed Pubal became renowned in southeast Poland due to his friendly interactions with humans and unwillingness to reintegrate into the wild. As of 2014 there were 1,434 wisents in Poland, out of which 1,212 were in free-range herds and 522 belonged to the wild population in the Białowieża Forest. Compared to 2013, the total population in 2014 increased by 4.1%, while the free-ranging population increased by 6.5%. Bison from Poland have also been transported beyond the country's borders to boost the local populations of other countries, among them Bulgaria, Spain, Romania, Czechia and others. Poland has been described as the world's breeding centre of the European bison, where the bison population doubled between 1995 and 2017, reaching 2,269 by the end of 2019 – the total population has been increasing by around 15% to 18% yearly. In July 2022 a small population was released into woodland by Canterbury in Kent to trial their reintroduction into the UK. In May 2024, a small population was released in a hunting area in central Portugal.

Genetic history
A 2003 study of mitochondrial DNA indicated four distinct maternal lineages in the tribe Bovini:
 * Taurine cattle and zebu
 * Wisent
 * American bison and yak
 * Banteng, gaur, and gayal

Y chromosome analysis associated wisent and American bison. An earlier study, using amplified fragment-length polymorphism fingerprinting, showed a close association of wisent and American bison and probably with yak. It noted the interbreeding of Bovini species made determining relationships problematic.

European bison can crossbreed with American bison. This hybrid is known in Poland as a żubrobizon. The products of a German interbreeding programme were destroyed after the Second World War. This programme was related to the impulse which created the Heck cattle. The cross-bred individuals created at other zoos were eliminated from breed books by the 1950s. A Russian back-breeding programme resulted in a wild herd of hybrid animals, which presently lives in the Caucasian Biosphere Reserve (550 animals in 1999).

Wisent-cattle hybrids also occur, similar to the North American beefalo. Cattle and European bison hybridise fairly readily. First-generation males are infertile. In 1847, a herd of wisent-cattle hybrids named żubroń was created by Leopold Walicki. The animals were intended to become durable and cheap alternatives to cattle. The experiment was continued by researchers from the Polish Academy of Sciences until the late 1980s. Although the program resulted in a quite successful animal that was both hardy and could be bred in marginal grazing lands, it was eventually discontinued. Currently, the only surviving żubroń herd consists of just a few animals in Białowieża Forest, Poland and Belarus.

In 2016, the first whole genome sequencing data from two European bison bulls from the Białowieża Forest revealed that the bison and bovine species diverged from about 1.7 to 0.85 Mya, through a speciation process involving limited gene flow. These data further support the occurrence of more recent secondary contacts, posterior to the divergence between Bos primigenius primigenius and B. p. namadicus (ca. 150,000 years ago), between the wisent and (European) taurine cattle lineages. An independent study of mitochondrial DNA and autosomal markers confirmed these secondary contacts (with an estimate of up to 10% of bovine ancestry in the modern wisent genome) leading the authors to go further in their conclusions by proposing the wisent to be a hybrid between steppe bison and aurochs with a hybridisation event originating before 120,000 years ago. However, other studies considered the 10% estimate for aurochs gene flow a gross overstimate and based on flawed data, and not supported by the data from the full nuclear genome of the wisent.

Some of the authors however support the hypothesis that similarity of wisent and cattle (Bos) mitochondrial genomes is result of incomplete lineage sorting during divergence of Bos and Bison from their common ancestors rather than further post-speciation gene flow (ancient hybridisation between Bos and Bison). But they agree that limited gene flow from Bos primigenius taurus could account for the affiliation between wisent and cattle nuclear genomes (in contrast to mitochondrial ones).

Alternatively, genome sequencing completed on remains attributed to the Pleistocene woodland bison (B. schoetensacki), and published in 2017, posited that genetic similarities between the Pleistocene woodland bison and the wisent suggest that B. schoetensaki was the ancestor of the European wisent. However, other studies have disputed the attribution of the remains to this species, otherwise known from remains hundreds of thousands of years older, instead referring them to an unnamed lineage of bison closely related to B. bonasius. A 2018 study proposed that the lineage leading to the wisent and to the lineage ancestral to both the American bison and Bison priscus had split over 1 million years ago, with the mitochondrial DNA discrepancy being the result of incomplete lineage sorting. The authors also proposed that during the late Middle Pleistocene there had been interbreeding between the ancestor of the wisent and the common ancestor of Bison priscus and the American bison.

Social structure and territorial behaviours

The European bison is a herd animal, which lives in both mixed and solely male groups. Mixed groups consist of adult females, calves, young aged 2–3 years, and young adult bulls. The average herd size is dependent on environmental factors, though on average, they number eight to 13 animals per herd. Herds consisting solely of bulls are smaller than mixed ones, containing two individuals on average. European bison herds are not family units. Different herds frequently interact, combine, and quickly split after exchanging individuals.

Bison social structure has been described by specialists as a matriarchy, as it is the cows of the herd that lead it, and decide where the entire group moves to graze. Although larger and heavier than the females, the oldest and most powerful male bulls are usually satellites that hang around the edges of the herd to protect the group. Bulls begin to serve a more active role in the herd when a danger to the group's safety appears, as well as during the mating season – when they compete with each other.

Territory held by bulls is correlated by age, with young bulls aged between five and six tending to form larger home ranges than older males. The European bison does not defend territory, and herd ranges tend to greatly overlap. Core areas of territory are usually sited near meadows and water sources.

Reproduction
The rutting season occurs from August through to October. Bulls aged 4–6 years, though sexually mature, are prevented from mating by older bulls. Cows usually have a gestation period of 264 days, and typically give birth to one calf at a time.

On average, male calves weigh 27.6 kg at birth, and females 24.4 kg. Body size in males increases proportionately to the age of 6 years. While females have a higher increase in body mass in their first year, their growth rate is comparatively slower than that of males by the age of 3–5. Bulls reach sexual maturity at the age of two, while cows do so in their third year.

European bison have lived as long as 30 years in captivity, but in the wild their lifespans are shorter. The lifespan of a bison in the wild is usually between 18 and 24 years, though females live longer than males. Productive breeding years are between four and 20 years of age in females, and only between six and 12 years of age in males.

Diet
European bison feed predominantly on grasses, although they also browse on shoots and leaves; in summer, an adult male can consume 32 kg of food in a day. European bison in the Białowieża Forest in Poland have traditionally been fed hay in the winter for centuries, and large herds may gather around this diet supplement. European bison need to drink every day, and in winter can be seen breaking ice with their heavy hooves.

Differences from American bison
Although superficially similar, a number of physical and behavioural differences are seen between the European bison and the American bison. The bison has 14 pairs of ribs, while the American bison has 15. Adult European bison are (on average) taller than American bison, and have longer legs. European bison tend to browse more, and graze less than their American relatives, due to their necks being set differently. Compared to the American bison, the nose of the European bison is set further forward than the forehead when the neck is in a neutral position.

The body of the wisent is less hairy, though its tail is hairier than that of the American species. The horns of the European bison point forward through the plane of their faces, making them more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison, which favours charging. European bison are less tameable than the American ones, and breed with domestic cattle less readily.

The European bison is less shaggy, with a more lanky body shape.

In terms of behavioural capability, European bison runs slower and with less stamina yet jumps higher and longer than American bisons, showing signs of more developed adaptations into mountainous habitats.

Conservation
The protection of the European bison has a long history; between the 15th and 18th centuries, those in the forest of Białowieża were protected and their diet supplemented. Efforts to restore this species to the wild began in 1929, with the establishment of the Bison Restitution Centre at Białowieża, Poland. Subsequently, in 1948, the Bison Breeding Centre was established within the Prioksko-Terrasny Biosphere Reserve.

The modern herds are managed as two separate lines – one consisting of only Bison bonasus bonasus (all descended from only seven animals) and one consisting of all 12 ancestors, including the one B. b. caucasicus bull. The latter is generally not considered a separate subspecies because they contain DNA from both B. b. bonasus and B. b. caucasicius, although some scientists classify them as a new subspecies, B. b. montanus. Only a limited amount of inbreeding depression from the population bottleneck has been found, having a small effect on skeletal growth in cows and a small rise in calf mortality. Genetic variability continues to shrink. From five initial bulls, all current European bison bulls have one of only two remaining Y chromosomes.

Reintroduction

Beginning in 1951, European bison have been reintroduced into the wild, including some areas where they were never found wild. Free-ranging herds are currently found in Poland, Lithuania, Belarus, Ukraine, Bulgaria, Romania, Russia, Slovakia, Latvia, Switzerland, Kyrgyzstan, Germany, and in forest preserves in the Western Caucasus. The Białowieża Primeval Forest, an ancient woodland that straddles the border between Poland and Belarus, continues to have the largest free-living European bison population in the world with around 1000 wild bison counted in 2014. Herds have also been introduced in Moldova (2005), Spain (2010), Denmark (2012), ,the Czech Republic (2014), and Portugal (2024)

Reintroduction of bison to a 20 square mile grasslands area in the Țarcu Mountains of Romania in 2014 was found to have resulted in an additional 54,000 tons of carbon draw-down annually.

The Wilder Blean project, headed up by the Wildwood Trust and Kent Wildlife Trust, introduced European bison to the UK for the first time in 6000 years (although there was an unsuccessful attempt in Scotland in 2011, and the European bison is not confirmed to be native to England while the British Isles once used to be inhabited by now-extinct Steppe bison and Pleistocene woodland bison). The herd of 3 females, with plans to also release a male in the following months, was set free in July 2022 within a 2,500-acre conservation area in West Blean and Thornden Woods, near Canterbury. Unknown to the rangers, one of the females was pregnant and gave birth to a calf in October 2022, marking the first wild bison born in the UK for the first time in millennia.

As below-mentioned, there are established herds in Spain, Portugal and Italy, however European bison has not been recorded naturally from the Iberian and Italian Peninsulas, while these regions were once inhabited by Pleistocene woodland bison and Steppe bison.

Numbers by country
The total worldwide population recorded in 2019 was around 7,500 – about half of this number being in Poland and Belarus, with over 25% of the global population located in Poland alone. For 2016, the number was 6,573 (including 4,472 free-ranging) and has been increasing. Some local populations are estimated as:
 * 🇦🇹 austria: 10 animals
 * 🇦🇿 azerbaijan: 29 animals in 2021.
 * 🇧🇾 belarus: 2,385 animals in 2023.
 * 🇧🇬 bulgaria: Around 150 animals in northeastern Bulgaria; a smaller population has been reintroduced in the eastern Rhodope Mountains.
 * undefined: 106 animals in 2017.
 * 🇩🇰 denmark: Two herds were established in the summer of 2012, as part of conservation of the species. First, fourteen animals were released in meadows near the town of Randers, and later, seven animals on Bornholm. In June 2012, one male and six females were moved from Poland to the Danish island Bornholm. The plan was to examine if it is possible to establish a wild population of bison on the island over a five-year period. In 2018, it was decided to keep the bison on Bornholm, but maintained within the large fenced-in part of the Almindingen forest where originally introduced. In 2019, the bison that initially had been introduced near Randers were moved to the more suitable and spacious Lille Vildmose; these were supplemented by seven animals from the Netherlands in 2021.
 * 🇫🇷 france: One herd was established in 2005 in the Alps near the village of Thorenc (close to the city of Grasse), as part of conservation of the species. In 2015, it contained around 50 animals.
 * 🇩🇪 germany: A herd of 8 animals (1 male, 5 females, and 2 calves) was released into nature in April 2013 at the Rothaarsteig natural reserve near Bad Berleburg (North Rhine-Westphalia) after 850 years of absence since the species became extinct in that region. As of May 2015, 13 free-roaming wisents lived there. In September 2017 one of the free-living Polish animals swam the border river Oder and migrated to Germany. It was the first wild bison seen in Germany for more than 250 years. German authorities ordered the animal to be killed and it was shot dead by hunters in September 2017. As of 2020, the population has steadily increased to 26 individuals, living in one subpopulation.
 * 🇭🇺 hungary: 11 animals in the Őrség National Park and few more in the Körös-Maros National Park.
 * 🇮🇹 italy: A small herd can be found in the Natura Viva Park near Verona, Italy, where the animals are protected and are prepared to be put in nature again in the wild areas of Romania.
 * 🇰🇬 kyrgyzstan: Animals were reintroduced at one point.
 * 🇱🇻 latvia: Animals were reintroduced in Pape Nature Reserve in 2007.
 * 🇱🇹 lithuania: 214 free-ranging animals as of 2017.
 * 🇲🇩 moldova: Extirpated from Moldova since the 18th century, wisents were reintroduced with the arrival of three European bison from Białowieża Forest in Poland several days before Moldova's Independence Day on 27 August 2005. Moldova is currently interested in expanding their wisent population, and began talks with Belarus in 2019 regarding a bison exchange program between the two countries. Bisons can be found in Pădurea Domnească.
 * 🇳🇱 netherlands: Natuurpark Lelystad: In 1976, the first wisent arrived from Białowieża. Natuurpark Lelystad is a breeding centre with a herd of approx. 25 animals living together with Przewalski horses. All wisents are registered in the European Studbook and are of the Lowland line. It is one of the suppliers for re-introduction projects in Europe. Kraansvlak herd established in 2007 with three wisents, and expanded to six in 2008; the Maashorst herd established in 2016 with 11 wisents; and the Veluwe herd established in 2016 with a small herd. In 2020 a new herd of 14 bison was established in the Slikken van de Heen. Numbers at the end of 2017 were: Lelystad 24, Kraansvlak 22, Maashorst 15 and the Veluwe 5, for a total of 66 animals.
 * 🇵🇱 poland: By the end of 2019 the number was 2,269, of which 2,048 were free-roaming and 221 were living in captivity, including zoos. A total of 770 belonged to the wild population in the Białowieża Forest and 668 to Bieszczady National Park. The total population has been increasing by around 15% to 18% yearly. Between 1995 and 2017 the number of bison in Poland doubled; from 2012 to 2017 it rose by 30%. Poland has been described as the world's breeding centre of the European bison. Zubr from Poland have also been transported beyond the country's borders to boost the local populations of other countries – among them Bulgaria, Czechia, Denmark, Moldova, Romania, Spain, Switzerland, and others.  As the number of animals is growing, more bison are spotted in areas where they have not been seen in centuries, especially migrating males in Spring. The placement of about 40 free-roaming bison in the Lasy Janowskie in 2020/2021 resulted in ecologists' efforts to redesign some bridges of the S19 highway (constructed in 2020-2022) to allow large animals to cross it.

 * 🇵🇹 portugal: A herd of 8 bisons were introduced in central Portugal for the first time in 2024 in Termas de Monfortinho and Herdade do Vale Freitoso, through the "Rewilding Portugal" programme.
 * 🇷🇴 romania: The European bison were reintroduced in 1958, when the first two animals were brought from Poland and kept in a reserve in Hațeg. Similar locations later appeared in Vama Buzăului (Valea Zimbrilor Nature Reserve) and Bucșani, Dâmbovița. The idea of free bison, on the Romanian territory, was born in 1999, through a program supported by the World Bank and the European Union. Almost 160 free-roaming animals, as of 2019, population slowly increasing in the four areas where wild bison can be found: Northern Romania – Vânători-Neamț Natural Park, and South-West Romania – Țarcu Mountains and Poiana Ruscă Mountains, as part of the Life-Bison project initiated by WWF Romania and Rewilding Europe, with co-funding from the EU through its LIFE Programme, but also in the Southern Carpathians, in the Făgăraș Mountains, as part of the Foundation Conservation Carpathia project, carried out within the LIFE Carpathia project. Since 2019, Foundation Conservation Carpathia has started to reintroduce the European Bison in the Făgăraș Mountains, after more than 200 years since their disappearance from the central forests of Romania. Foundation Conservation Carpathia aims to reintroduce 75 European bisons into the Făgăraș Mountains. In June 2024, 14 additional bison were brought to the southern Carpathian mountains from Germany and Sweden.
 * 🇷🇺 russia: As of 2020, the population of Wisents in Russia has greatly recovered and stands at 1,588 individuals.
 * 🇷🇸 serbia: In March 2022, 5 animals (one bull and four cows) were reintroduced where bison went extinct c.1800. Animals were transported from the Białowieża Forest and reintroduced on the Fruška Gora mountain.
 * 🇸🇰 slovakia: A bison reserve was established in Topoľčianky in 1958. The reserve has a maximum capacity of 13 animals but has bred around 180 animals for various zoos. As of 2020, there was also a wild breeding herd of 48 animals in Poloniny National Park with an increasing population.
 * 🇪🇸 spain: Two herds in northern Spain were established in 2010. As of 2018, the total population neared a hundred animals, half of them in Castile and León, but also in Asturias, Valencia, Extremadura and the Pyrenees.
 * 🇸🇪 sweden: There are approximately 139 animals.
 * 🇨🇭 switzerland: More than 50 animals. Coming from Poland, one male and four females were introduced in November 2019 into the natural reserve and forest of Suchy, Vaud Canton, western Switzerland. On 15 June 2020, the first baby of that population was born. Besides the Suchy breeding station, several zoos in Switzerland are keeping bison too. From September 2022, at least five animals will be kept in semi-freedom in Welschenrohr, with hiking paths cutting through the enclosure.
 * 🇺🇦 ukraine: A population of around 400 animals, population was recently introduced to several national parks and is increasing.
 * undefined: In 2011, 3 animals were introduced into Alladale Wilderness Reserve in Scotland. Plans to move more into the reserve were made, but the project failed due to not being "well thought through", and the project was terminated in 2013. 11 years later, 3 female bison were introduced to the West Blean and Thornden Woods in Kent, England on 18 July 2022. A calf, also female, was unexpectedly born in September 2022, bringing the total number to 4. On 24 December 2022 a bull was introduced after delays brought about by Brexit-related complications. This makes these 5 bison the first "complete" wild herd in the UK in thousands of years.

Distribution

The largest European bison herds — of both captive and wild populations — are still located in Poland and Belarus, the majority of which can be found in the Białowieża Forest including the most numerous population of free-living European bison in the world with most of the animals living on the Polish side of the border. Poland remains the world's breeding centre for the wisent. In the years 1945 to 2014, from the Białowieża National Park alone, 553 specimens were sent to most captive populations of the bison in Europe as well as all breeding sanctuaries for the species in Poland.

Since 1983, a small reintroduced population lives in the Altai Mountains. This population suffers from inbreeding depression and needs the introduction of unrelated animals for "blood refreshment". In the long term, authorities hope to establish a population of about 1,000 animals in the area. One of the northernmost current populations of the European bison lives in Vologodskaya Oblast in the Northern Dvina valley at about 60°N. It survives without supplementary winter feeding. Another Russian population lives in the forests around the Desna River on the border between Russia and Ukraine. The north-easternmost population lives in Pleistocene Park south of Chersky in Siberia, a project to recreate the steppe ecosystem which began to be altered 10,000 years ago. Five wisents were introduced on 24 April 2011. The wisents were brought to the park from the Prioksko-Terrasny Nature Reserve near Moscow. The bison originated from a population in Denmark. Winter temperatures often drop below −50 °C. Four of the five bison have subsequently died due to problems acclimatizing to the low winter temperature.

Plans are being made to reintroduce two herds in Germany and in the Netherlands in Oostvaardersplassen Nature Reserve in Flevoland as well as the Veluwe. In 2007, a bison pilot project in a fenced area was begun in Zuid-Kennemerland National Park in the Netherlands. Because of their limited genetic pool, they are considered highly vulnerable to illnesses such as foot-and-mouth disease. In March 2016, a herd was released in the Maashorst Nature Reserve in North Brabant. Zoos in 30 countries also have quite a few bison involved in captive-breeding programs.

Cultural significance
Representations of the European bison from different ages, across millennia of human society's existence, can be found throughout Eurasia in the form of drawings and rock carvings; one of the oldest and most famous instances of the latter can be found in the Cave of Altamira, present-day Spain, where cave art featuring the wisent from the Upper Paleolithic was discovered. The bison has also been represented in a wide range of art in human history, such as sculptures, paintings, photographs, glass art, and more. Sculptures of the wisent constructed in the 19th and 20th centuries continue to stand in a number of European cities; arguably the most notable of these are the zubr statue in Spała from 1862 designed by Mihály Zichy and the two bison sculptures in Kiel sculpted by August Gaul in 1910–1913. However, a number of other monuments to the animal also exist, such as those in Hajnówka and Pszczyna or at the Kyiv Zoo entrance. Mikołaj Hussowczyk, a poet writing in Latin about the Grand Duchy of Lithuania during the early 16th century, described the bison in a historically significant fictional work from 1523.

The European bison is considered one of the national animals of Poland and Belarus. Due to this and the fact that half of the worldwide European bison population can be found spread across these two countries, the wisent is still featured prominently in the heraldry of these neighbouring states (especially in the overlapping region of Eastern Poland and Western Belarus). Examples in Poland include the coats of arms of: the counties of Hajnówka and Zambrów, the towns Sokółka and Żywiec, the villages Białowieża and Narewka, as well as the coats of arms of the Pomian and Wieniawa families. Examples in Belarus include the Grodno and Brest voblasts, the town of Svislach, and others. The European bison can also be found on the coats of arms of places in neighbouring countries: Perloja in southern Lithuania, Lypovets in west-central Ukraine, and Zubří in east Czechia – as well as further outside the region, such as Kortezubi in the Basque Country, and Jabel in Germany.

A flavoured vodka called Żubrówka, originating as a recipe of the szlachta of the Kingdom of Poland in the 14th century, has since 1928 been industrially produced as a brand in Poland. In the decades that followed, it became known as the "world's best known Polish vodka" and sparked the creation of a number of copy brands inspired by the original in Belarus, Russia, Germany, as well as other brands in Poland. The original Polish brand is known for placing a decorative blade of bison grass from the Białowieża Forest in each bottle of their product; both the plant's name in Polish and the vodka are named after żubr, the Polish name for the European bison. The bison also appears commercially as a symbol of a number of other Polish brands, such as the popular beer brand Żubr and on the logo of Poland's second largest bank, Bank Pekao S.A.

Argumentum ad baculum

Argumentum ad baculum (Latin for "argument to the cudgel" or "appeal to the stick") is the fallacy committed when one makes an appeal to force to bring about the acceptance of a conclusion. One participates in argumentum ad baculum when one emphasizes the negative consequences of holding the contrary position, regardless of the contrary position's truth value—particularly when the argument-maker himself causes (or threatens to cause) those negative consequences. It is a special case of the appeal to consequences.

Examples
The Stanford Encyclopedia of Philosophy gives this example of argumentum ad baculum:
 * If you don't join our demonstration against the expansion of the park, we will evict you from your apartment;
 * So, you should join our demonstration against the expansion of the park.

The phrase has also been used to describe the 1856 caning of Charles Sumner, an abolitionist Senator, by one of his pro-slavery opponents, Preston Brooks, on the floor of the United States Senate.

French and Indian War

The French and Indian War (1754–1763) was a theater of the Seven Years' War, which pitted the North American colonies of the British Empire against those of the French, each side being supported by various Native American tribes. At the start of the war, the French colonies had a population of roughly 60,000 settlers, compared with 2 million in the British colonies. The outnumbered French particularly depended on their native allies.

Two years into the war, in 1756, Great Britain declared war on France, beginning the worldwide Seven Years' War. Many view the French and Indian War as being merely the American theater of this conflict; however, in the United States the French and Indian War is viewed as a singular conflict which was not associated with any European war. French Canadians call it the guerre de la Conquête ('War of the Conquest').

The British colonists were supported at various times by the Iroquois, Catawba, and Cherokee tribes, and the French colonists were supported by Wabanaki Confederacy members Abenaki and Mi'kmaq, and the Algonquin, Lenape, Ojibwa, Ottawa, Shawnee, and Wyandot (Huron). Fighting took place primarily along the frontiers between New France and the British colonies, from the Province of Virginia in the south to Newfoundland in the north. It began with a dispute over control of the confluence of the Allegheny River and Monongahela River called the Forks of the Ohio, and the site of the French Fort Duquesne at the location that later became Pittsburgh, Pennsylvania. The dispute erupted into violence in the Battle of Jumonville Glen in May 1754, during which Virginia militiamen under the command of 22-year-old George Washington ambushed a French patrol.

In 1755, six colonial governors met with General Edward Braddock, the newly arrived British Army commander, and planned a four-way attack on the French. None succeeded, and the main effort by Braddock proved a disaster; he lost the Battle of the Monongahela on July 9, 1755, and died a few days later. British operations failed in the frontier areas of the Province of Pennsylvania and the Province of New York during 1755–57 due to a combination of poor management, internal divisions, effective Canadien scouts, French regular forces, and Native warrior allies. In 1755, the British captured Fort Beauséjour on the border separating Nova Scotia from Acadia, and they ordered the expulsion of the Acadians (1755–64) soon afterwards. Orders for the deportation were given by Commander-in-Chief William Shirley without direction from Great Britain. The Acadians were expelled, both those captured in arms and those who had sworn the loyalty oath to the king. Natives likewise were driven off the land to make way for settlers from New England.

The British Pitt government fell due to disastrous campaigns in 1757, including a failed expedition against Louisbourg and the Siege of Fort William Henry; this last was followed by the Natives torturing and massacring their colonial victims. William Pitt came to power and significantly increased British military resources in the colonies at a time when France was unwilling to risk large convoys to aid the limited forces that they had in New France, preferring to concentrate their forces against Prussia and its allies who were now engaged in the Seven Years' War in Europe. The conflict in Ohio ended in 1758 with the British–American victory in the Ohio Country. Between 1758 and 1760, the British military launched a campaign to capture French Canada. They succeeded in capturing territory in surrounding colonies and ultimately the city of Quebec (1759). The following year the British were victorious in the Montreal Campaign in which the French ceded Canada in accordance with the Treaty of Paris (1763).

France also ceded its territory east of the Mississippi to Great Britain, as well as French Louisiana west of the Mississippi River to its ally Spain in compensation for Spain's loss to Britain of Spanish Florida. (Spain had ceded Florida to Britain in exchange for the return of Havana, Cuba.) France's colonial presence north of the Caribbean was reduced to the islands of Saint Pierre and Miquelon, confirming Great Britain's position as the dominant colonial power in northern America.

Nomenclature
In British America, wars were often named after the sitting British monarch, such as King William's War or Queen Anne's War. There had already been a King George's War in the 1740s during the reign of King George II, so British colonists named this conflict after their opponents, and it became known as the French and Indian War. This continues as the standard name for the war in the United States, although indigenous peoples fought on both sides of the conflict. It also led into the Seven Years' War overseas, a much larger conflict between France and Great Britain that did not involve the American colonies; some historians make a connection between the French and Indian War and the Seven Years' War overseas, but most residents of the United States consider them as two separate conflicts—only one of which involved the American colonies, and American historians generally use the traditional name. Less frequently used names for the war include the Fourth Intercolonial War and the Great War for the Empire.

In Europe, the French and Indian War is conflated into the Seven Years' War and not given a separate name. "Seven Years" refers to events in Europe, from the official declaration of war in 1756—two years after the French and Indian War had started—to the signing of the peace treaty in 1763. The French and Indian War in America, by contrast, was largely concluded in six years from the Battle of Jumonville Glen in 1754 to the capture of Montreal in 1760.

Canadians conflate both the European and American conflicts into the Seven Years' War (Guerre de Sept Ans). French Canadians also use the term "War of Conquest" (Guerre de la Conquête), since it is the war in which New France was conquered by the British and became part of the British Empire. In Quebec, this term was promoted by popular historians Jacques Lacoursière and Denis Vaugeois, who borrowed from the ideas of Maurice Séguin in considering this war as a dramatic tipping point of French Canadian identity and nationhood.

Background
At this time, North America east of the Mississippi River was largely claimed by either Great Britain or France. Large areas had no colonial settlements. The French population numbered about 75,000 and was heavily concentrated along the St. Lawrence River valley, with some also in Acadia (present-day New Brunswick and parts of Nova Scotia), including Île Royale (Cape Breton Island). Fewer lived in New Orleans; Biloxi, Mississippi; Mobile, Alabama; and small settlements in the Illinois Country, hugging the east side of the Mississippi River and its tributaries. French fur traders and trappers traveled throughout the St. Lawrence and Mississippi watersheds, did business with local Indian tribes, and often married Indian women. Traders married daughters of chiefs, creating high-ranking unions.

British settlers outnumbered the French 20 to 1 with a population of about 1.5 million ranged along the Atlantic coast of the continent from Nova Scotia and the Colony of Newfoundland in the north to the Province of Georgia in the south. Many of the older colonies' land claims extended arbitrarily far to the west, as the extent of the continent was unknown at the time when their provincial charters were granted. Their population centers were along the coast, but the settlements were growing into the interior. The British captured Nova Scotia from France in 1713, which still had a significant French-speaking population. Britain also claimed Rupert's Land where the Hudson's Bay Company traded for furs with local Indian tribes. Between the French and British colonists, large areas were dominated by Indian tribes. To the north, the Mi'kmaq and the Abenakis were engaged in Father Le Loutre's War and still held sway in parts of Nova Scotia, Acadia, and the eastern portions of the province of Canada, as well as much of Maine. The Iroquois Confederation dominated much of upstate New York and the Ohio Country, although Ohio also included Algonquian-speaking populations of Delaware and Shawnee, as well as Iroquoian-speaking Mingos. These tribes were formally under Iroquois rule and were limited by them in their authority to make agreements. The Iroquois Confederation initially held a stance of neutrality to ensure continued trade with both French and British. Though maintaining this stance proved difficult as the Iroquois Confederation tribes sided and supported French or British causes depending on which side provided the most beneficial trade.

The Southeast interior was dominated by Siouan-speaking Catawbas, Muskogee-speaking Creeks and Choctaw, and the Iroquoian-speaking Cherokee tribes. When war broke out, the French colonists used their trading connections to recruit fighters from tribes in western portions of the Great Lakes region, which was not directly subject to the conflict between the French and British; these included the Hurons, Mississaugas, Ojibwas, Winnebagos, and Potawatomi.

The British colonists were supported in the war by the Iroquois Six Nations and also by the Cherokees, until differences sparked the Anglo-Cherokee War in 1758. In 1758, the Province of Pennsylvania successfully negotiated the Treaty of Easton in which a number of tribes in the Ohio Country promised neutrality in exchange for land concessions and other considerations. Most of the other northern tribes sided with the French, their primary trading partner and supplier of arms. The Creeks and Cherokees were subject to diplomatic efforts by both the French and British to gain either their support or neutrality in the conflict. At this time, Spain claimed only the province of Florida in eastern America. It controlled Cuba and other territories in the West Indies that became military objectives in the Seven Years' War. Florida's European population was a few hundred, concentrated in St. Augustine. There were no French regular army troops stationed in America at the onset of war. New France was defended by about 3,000 troupes de la marine, companies of colonial regulars (some of whom had significant woodland combat experience). The colonial government recruited militia support when needed. The British had few troops. Most of the British colonies mustered local militia companies to deal with Indian threats, generally ill trained and available only for short periods, but they did not have any standing forces. Virginia, by contrast, had a large frontier with several companies of British regulars.

When hostilities began, the British colonial governments preferred operating independently of one another and of the government in London. This situation complicated negotiations with Indian tribes, whose territories often encompassed land claimed by multiple colonies. As the war progressed, the leaders of the British Army establishment tried to impose constraints and demands on the colonial administrations.

Céloron's expedition
New France's Governor-General Roland-Michel Barrin de La Galissonière was concerned about the incursion and expanding influence in the Ohio Country of British colonial traders such as George Croghan. In June 1747, he ordered Pierre-Joseph Céloron to lead a military expedition through the area. Its objectives were:
 * to reaffirm to New France's Indian allies that their trading arrangements with colonists were exclusive to those authorized by New France
 * to confirm Indian assistance in asserting and maintaining the French claim to the territories which French explorers had claimed
 * to discourage any alliances between Britain and local Indian tribes
 * to impress the Indians with a French show of force against British colonial settler incursion, unauthorized trading expeditions, and general trespass against French claims

Céloron's expedition force consisted of about 200 Troupes de la marine and 30 Indians, and they covered about 3000 mi between June and November 1749. They went up the St. Lawrence, continued along the northern shore of Lake Ontario, crossed the portage at Niagara, and followed the southern shore of Lake Erie. At the Chautauqua Portage near Barcelona, New York, the expedition moved inland to the Allegheny River, which it followed to the site of Pittsburgh. There Céloron buried lead plates engraved with the French claim to the Ohio Country. Whenever he encountered British colonial merchants or fur-traders, he informed them of the French claims on the territory and told them to leave.

Céloron's expedition arrived at Logstown where the Indians in the area informed him that they owned the Ohio Country and that they would trade with the British colonists regardless of the French. He continued south until his expedition reached the confluence of the Ohio and the Miami rivers, which lay just south of the village of Pickawillany, the home of the Miami chief known as "Old Briton". Céloron threatened Old Briton with severe consequences if he continued to trade with British colonists, but Old Briton ignored the warning. Céloron returned disappointedly to Montreal in November 1749.

Céloron wrote an extensively detailed report. "All I can say is that the Natives of these localities are very badly disposed towards the French," he wrote, "and are entirely devoted to the English. I don't know in what way they could be brought back." Even before his return to Montreal, reports on the situation in the Ohio Country were making their way to London and Paris, each side proposing that action be taken. Massachusetts governor William Shirley was particularly forceful, stating that British colonists would not be safe as long as the French were present.

Negotiations
The War of the Austrian Succession ended in 1748 with the signing of the Treaty of Aix-la-Chapelle, which was primarily focused on resolving issues in Europe. The issues of conflicting territorial claims between British and French colonies were turned over to a commission, but it reached no decision. Frontier areas were claimed by both sides, from Nova Scotia and Acadia in the north to the Ohio Country in the south. The disputes also extended into the Atlantic Ocean, where both powers wanted access to the rich fisheries of the Grand Banks off Newfoundland.

In 1749, the British government gave land to the Ohio Company of Virginia for the purpose of developing trade and settlements in the Ohio Country. The grant required that it settle 100 families in the territory and construct a fort for their protection. But the territory was also claimed by Pennsylvania, and both colonies began pushing for action to improve their respective claims. In 1750, Christopher Gist explored the Ohio territory, acting on behalf of both Virginia and the company, and he opened negotiations with the Indian tribes at Logstown. He completed the 1752 Treaty of Logstown in which the local Indians agreed to terms through their "Half-King" Tanacharison and an Iroquois representative. These terms included permission to build a strong house at the mouth of the Monongahela River on the modern site of Pittsburgh, Pennsylvania.

Escalation in Ohio Country
Governor-General of New France Marquis de la Jonquière died on March 17, 1752, and he was temporarily replaced by Charles le Moyne de Longueuil. His permanent replacement was to be the Marquis Duquesne, but he did not arrive in New France until 1752 to take over the post. The continuing British activity in the Ohio territories prompted Longueuil to dispatch another expedition to the area under the command of Charles Michel de Langlade, an officer in the Troupes de la Marine. Langlade was given 300 men, including French-Canadians and warriors of the Ottawa tribe. His objective was to punish the Miami people of Pickawillany for not following Céloron's orders to cease trading with the British. On June 21, the French war party attacked the trading center at Pickawillany, capturing three traders and killing 14 Miami Indians, including Old Briton. He was reportedly ritually cannibalized by some Indians in the expedition party.

Construction of French fortifications
In the spring of 1753, Paul Marin de la Malgue was given command of a 2,000-man force of Troupes de la Marine and Indians. His orders were to protect the King's land in the Ohio Valley from the British. Marin followed the route that Céloron had mapped out four years earlier. Céloron, however, had limited the record of French claims to the burial of lead plates, whereas Marin constructed and garrisoned forts. He first constructed Fort Presque Isle on Lake Erie's south shore near Erie, Pennsylvania, and he had a road built to the headwaters of LeBoeuf Creek. He then constructed a second fort at Fort Le Boeuf in Waterford, Pennsylvania, designed to guard the headwaters of LeBoeuf Creek. As he moved south, he drove off or captured British traders, alarming both the British and the Iroquois. Tanaghrisson was a chief of the Mingo Indians, who were remnants of Iroquois and other tribes who had been driven west by colonial expansion. He intensely disliked the French whom he accused of killing and eating his father. He traveled to Fort Le Boeuf and threatened the French with military action, which Marin contemptuously dismissed.

The Iroquois sent runners to the manor of William Johnson in upstate New York, who was the British Superintendent for Indian Affairs in the New York region and beyond. Johnson was known to the Iroquois as Warraghiggey, meaning "he who does great things." He spoke their languages and had become a respected honorary member of the Iroquois Confederacy in the area, and he was made a colonel of the Iroquois in 1746; he was later commissioned as a colonel of the Western New York Militia.

The Indian representatives and Johnson met with Governor George Clinton and officials from some of the other American colonies at Albany, New York. Mohawk Chief Hendrick was the speaker of their tribal council, and he insisted that the British abide by their obligations and block French expansion. Clinton did not respond to his satisfaction, and Hendrick said that the "Covenant Chain" was broken, a long-standing friendly relationship between the Iroquois Confederacy and the British Crown.

Virginia's response
Governor Robert Dinwiddie of Virginia was an investor in the Ohio Company, which stood to lose money if the French held their claim. He ordered 21-year-old Major George Washington (whose brother was another Ohio Company investor) of the Virginia Regiment to warn the French to leave Virginia territory in October 1753. Washington left with a small party, picking up Jacob Van Braam as an interpreter, Christopher Gist (a company surveyor working in the area), and a few Mingos led by Tanaghrisson. On December 12, Washington and his men reached Fort Le Boeuf.

Jacques Legardeur de Saint-Pierre succeeded Marin as commander of the French forces after Marin died on October 29, and he invited Washington to dine with him. Over dinner, Washington presented Saint-Pierre with the letter from Dinwiddie demanding an immediate French withdrawal from the Ohio Country. Saint-Pierre said, "As to the Summons you send me to retire, I do not think myself obliged to obey it." He told Washington that France's claim to the region was superior to that of the British, since René-Robert Cavelier, Sieur de La Salle had explored the Ohio Country nearly a century earlier.

Washington's party left Fort Le Boeuf early on December 16 and arrived in Williamsburg on January 16, 1754. He stated in his report, "The French had swept south", detailing the steps which they had taken to fortify the area, and their intention to fortify the confluence of the Allegheny and Monongahela rivers.

Course of war
Even before Washington returned, Dinwiddie had sent a company of 40 men under William Trent to that point where they began construction of a small stockaded fort in the early months of 1754. Governor Duquesne sent additional French forces under Claude-Pierre Pécaudy de Contrecœur to relieve Saint-Pierre during the same period, and Contrecœur led 500 men south from Fort Venango on April 5, 1754. These forces arrived at the fort on April 16, but Contrecœur generously allowed Trent's small company to withdraw. He purchased their construction tools to continue building what became Fort Duquesne.

Early engagements
Dinwiddie had ordered Washington to lead a larger force to assist Trent in his work, and Washington learned of Trent's retreat while he was en route. Mingo sachem Tanaghrisson had promised support to the British, so Washington continued toward Fort Duquesne and met with him. He then learned of a French scouting party in the area from a warrior sent by Tanaghrisson, so he added Tanaghrisson's dozen Mingo warriors to his own party. Washington's combined force of 52 ambushed 40 Canadiens (French colonists of New France) on the morning of May 28 in what became known as the Battle of Jumonville Glen. They killed many of the Canadiens, including their commanding officer Joseph Coulon de Jumonville, whose head was reportedly split open by Tanaghrisson with a tomahawk. Historian Fred Anderson suggests that Tanaghrisson was acting to gain the support of the British and to regain authority over his own people. They had been inclined to support the French, with whom they had long trading relationships. One of Tanaghrisson's men told Contrecoeur that Jumonville had been killed by British musket fire. Historians generally consider the Battle of Jumonville Glen as the opening battle of the French and Indian War in North America, and the start of hostilities in the Ohio valley. Following the battle, Washington pulled back several miles and established Fort Necessity, which the Canadians attacked under the command of Jumonville's brother at the Battle of Fort Necessity on July 3. Washington surrendered and negotiated a withdrawal under arms. One of his men reported that the Canadian force was accompanied by Shawnee, Delaware, and Mingo warriors—just those whom Tanaghrisson was seeking to influence.

News of the two battles reached England in August. After several months of negotiations, the government of the Duke of Newcastle decided to send an army expedition the following year to dislodge the French. They chose Major General Edward Braddock to lead the expedition. Word of the British military plans leaked to France well before Braddock's departure for North America. In response, King Louis XV dispatched six regiments to New France under the command of Baron Dieskau in 1755. The British sent out their fleet in February 1755, intending to blockade French ports, but the French fleet had already sailed. Admiral Edward Hawke detached a fast squadron to North America in an attempt to intercept them. In a second British action, Admiral Edward Boscawen fired on the French ship Alcide on June 8, 1755, capturing her and two troop ships. The British harassed French shipping throughout 1755, seizing ships and capturing seamen. These actions contributed to the eventual formal declarations of war in spring 1756.

An early important political response to the opening of hostilities was the convening of the Albany Congress in June and July, 1754. The goal of the congress was to formalize a unified front in trade and negotiations with the Indians, since the allegiance of the various tribes and nations was seen to be pivotal in the war that was unfolding. The plan that the delegates agreed to was neither ratified by the colonial legislatures nor approved by the Crown. Nevertheless, the format of the congress and many specifics of the plan became the prototype for confederation during the War of Independence.

British campaigns, 1755
The British formed an aggressive plan of operations for 1755. General Braddock was to lead the expedition to Fort Duquesne, while Massachusetts governor William Shirley was given the task of fortifying Fort Oswego and attacking Fort Niagara. Sir William Johnson was to capture Fort St. Frédéric at Crown Point, New York, and Lieutenant Colonel Robert Monckton was to capture Fort Beauséjour to the east on the frontier between Nova Scotia and Acadia. Braddock led about 1,500 army troops and provincial militia on the Braddock expedition in June 1755 to take Fort Duquesne, with George Washington as one of his aides. The expedition was a disaster. It was attacked by French regulars, Canadian Militiamen, and Indian warriors ambushing them from hiding places up in trees and behind logs, and Braddock called for a retreat. He was killed and approximately 1,000 British soldiers were killed or injured. The remaining 500 British troops retreated to Virginia, led by Washington. Washington and Thomas Gage played key roles in organizing the retreat—two future opponents in the American Revolutionary War.

The British government initiated a plan to increase their military capability in preparation for war following news of Braddock's defeat and the start of parliament's session in November 1755. Among the early legislative measures were the Recruiting Act 1756, the Commissions to Foreign Protestants Act 1756 for the Royal American Regiment, the Navigation Act 1756, and the Continuance of Laws Act 1756. England passed the Naval Prize Act 1756 following the proclamation of war on May 17 to allow the capture of ships and establish privateering.

The French acquired a copy of the British war plans, including the activities of Shirley and Johnson. Shirley's efforts to fortify Oswego were bogged down in logistical difficulties, exacerbated by his inexperience in managing large expeditions. In conjunction, he was made aware that the French were massing for an attack on Fort Oswego in his absence when he planned to attack Fort Niagara. As a response, he left garrisons at Oswego, Fort Bull, and Fort Williams, the last two located on the Oneida Carry between the Mohawk River and Wood Creek at Rome, New York. Supplies were cached at Fort Bull for use in the projected attack on Niagara.

Johnson's expedition was better organized than Shirley's, which was noticed by New France's governor the Marquis de Vaudreuil. Vaudreuil had been concerned about the extended supply line to the forts on the Ohio, and he had sent Baron Dieskau to lead the defenses at Frontenac against Shirley's expected attack. Vaudreuil saw Johnson as the larger threat and sent Dieskau to Fort St. Frédéric to meet that threat. Dieskau planned to attack the British encampment at Fort Edward at the upper end of navigation on the Hudson River, but Johnson had strongly fortified it, and Dieskau's Indian support was reluctant to attack. The two forces finally met in the bloody Battle of Lake George between Fort Edward and Fort William Henry. The battle ended inconclusively, with both sides withdrawing from the field. Johnson's advance stopped at Fort William Henry, and the French withdrew to Ticonderoga Point, where they began the construction of Fort Carillon (later renamed Fort Ticonderoga after the British captured it in 1759). Colonel Monckton captured Fort Beauséjour in June 1755 in the sole British success that year, cutting off the French Fortress Louisbourg from land-based reinforcements. To cut vital supplies to Louisbourg, Nova Scotia's Governor Charles Lawrence ordered the deportation of the French-speaking Acadian population from the area. Monckton's forces, including companies of Rogers' Rangers, forcibly removed thousands of Acadians, chasing down many who resisted and sometimes committing atrocities. Cutting off supplies to Louisbourg led to its demise. The Acadian resistance was sometimes quite stiff, in concert with Indian allies including the Mi'kmaq, with ongoing frontier raids against Dartmouth and Lunenburg, among others. The only clashes of any size were at Petitcodiac in 1755 and at Bloody Creek near Annapolis Royal in 1757, other than the campaigns to expel the Acadians ranging around the Bay of Fundy, on the Petitcodiac and St. John rivers, and Île Saint-Jean.

French victories, 1756–1757
Following the death of Braddock, William Shirley assumed command of British forces in North America, and he laid out his plans for 1756 at a meeting in Albany in December 1755. He proposed renewing the efforts to capture Niagara, Crown Point, and Duquesne, with attacks on Fort Frontenac on the north shore of Lake Ontario and an expedition through the wilderness of the Maine district and down the Chaudière River to attack the city of Quebec. His plan, however, got bogged down by disagreements and disputes with others, including William Johnson and New York's Governor Sir Charles Hardy, and consequently gained little support. Newcastle replaced him in January 1756 with Lord Loudoun, with Major General James Abercrombie as his second in command. Neither of these men had as much campaign experience as the trio of officers whom France sent to North America. French regular army reinforcements arrived in New France in May 1756, led by Major General Louis-Joseph de Montcalm and seconded by the Chevalier de Lévis and Colonel François-Charles de Bourlamaque, all experienced veterans from the War of the Austrian Succession. On May 17, 1756, Britain formally declared war on France, which expanded the war into Europe and came to be known as the Seven Years' War.

Governor Vaudreuil had ambitions to become the French commander in chief, in addition to his role as governor, and he acted during the winter of 1756 before those reinforcements arrived. Scouts had reported the weakness of the British supply chain, so he ordered an attack against the forts which Shirley had erected at the Oneida Carry. In the Battle of Fort Bull, French forces destroyed the fort and large quantities of supplies, including 45,000 pounds of gunpowder. They set back any British hopes for campaigns on Lake Ontario and endangered the Oswego garrison, already short on supplies. French forces in the Ohio valley also continued to intrigue with Indians throughout the area, encouraging them to raid frontier settlements. This led to ongoing alarms along the western frontiers, with streams of refugees returning east to get away from the action. The new British command was not in place until July. Abercrombie arrived in Albany but refused to take any significant actions until Loudoun approved them, and Montcalm took bold action against his inertia. He built on Vaudreuil's work harassing the Oswego garrison and executed a strategic feint by moving his headquarters to Ticonderoga, as if to presage another attack along Lake George. With Abercrombie pinned down at Albany, Montcalm slipped away and led the successful attack on Oswego in August. In the aftermath, Montcalm and the Indians under his command disagreed about the disposition of prisoners' personal effects. The Europeans did not consider them prizes and prevented the Indians from stripping the prisoners of their valuables, which angered the Indians.

Loudoun was a capable administrator but a cautious field commander, and he planned one major operation for 1757: an attack on New France's capital of Quebec. He left a sizable force at Fort William Henry to distract Montcalm and began organizing for the expedition to Quebec. He was then ordered to attack Louisbourg first by William Pitt, the Secretary of State responsible for the colonies. The expedition was beset by delays of all kinds but was finally ready to sail from Halifax, Nova Scotia, in early August. In the meantime, French ships had escaped the British blockade of the French coast, and a fleet awaited Loudoun at Louisbourg which outnumbered the British fleet. Faced with this strength, Loudoun returned to New York amid news that a massacre had occurred at Fort William Henry. French irregular forces (Canadian scouts and Indians) harassed Fort William Henry throughout the first half of 1757. In January, they ambushed British rangers near Ticonderoga. In February, they launched a raid against the position across the frozen Lake George, destroying storehouses and buildings outside the main fortification. In early August, Montcalm and 7,000 troops besieged the fort, which capitulated with an agreement to withdraw under parole. When the withdrawal began, some of Montcalm's Indian allies attacked the British column because they were angry about the lost opportunity for loot, killing and capturing several hundred men, women, children, and slaves. The aftermath of the siege may have contributed to the transmission of smallpox into remote Indian populations, as some Indians were reported to have traveled from beyond the Mississippi to participate in the campaign and returned afterward. Modern writer William Nester believes that the Indians might have been exposed to European carriers, although no proof exists.

British conquest, 1758–1760
Vaudreuil and Montcalm were minimally resupplied in 1758, as the British blockade of the French coastline limited French shipping. The situation in New France was further exacerbated by a poor harvest in 1757, a difficult winter, and the allegedly corrupt machinations of François Bigot, the intendant of the territory. His schemes to supply the colony inflated prices and were believed by Montcalm to line his pockets and those of his associates. A massive outbreak of smallpox among western Indian tribes led many of them to stay away from trading in 1758. The disease probably spread through the crowded conditions at William Henry after the battle; yet the Indians blamed the French for bringing "bad medicine" as well as denying them prizes at Fort William Henry.

Montcalm focused his meager resources on the defense of the St. Lawrence, with primary defenses at Carillon, Quebec, and Louisbourg, while Vaudreuil argued unsuccessfully for a continuation of the raiding tactics that had worked quite effectively in previous years. The British failures in North America combined with other failures in the European theater and led to Newcastle's fall from power along with the Duke of Cumberland, his principal military advisor. Newcastle and Pitt joined in an uneasy coalition in which Pitt dominated the military planning. He embarked on a plan for the 1758 campaign that was largely developed by Loudoun. He had been replaced by Abercrombie as commander in chief after the failures of 1757. Pitt's plan called for three major offensive actions involving large numbers of regular troops supported by the provincial militias, aimed at capturing the heartlands of New France. Two of the expeditions were successful, with Fort Duquesne and Louisbourg falling to sizable British forces.

1758
The Forbes Expedition was a British campaign in September–October 1758, with 6,000 troops led by General John Forbes sent to drive out the French from the contested Ohio Country. The French withdrew from Fort Duquesne and left the British in control of the Ohio River Valley. The great French fortress at Louisbourg in Nova Scotia was captured after a siege. The third invasion was stopped with the improbable French victory in the Battle of Carillon, in which 3,600 Frenchmen defeated Abercrombie's force of 18,000 regulars, militia, and Indian allies outside the fort which the French called Carillon and the British called Ticonderoga. Abercrombie saved something from the disaster when he sent John Bradstreet on an expedition that successfully destroyed Fort Frontenac, including caches of supplies destined for New France's western forts and furs destined for Europe. Abercrombie was recalled and replaced by Jeffery Amherst, victor at Louisbourg.

The French had generally poor results in 1758 in most theaters of the war. The new foreign minister was the duc de Choiseul, and he decided to focus on an invasion of Britain to draw British resources away from North America and the European mainland. The invasion failed both militarily and politically, as Pitt again planned significant campaigns against New France and sent funds to Britain's mainland ally of Prussia, while the French Navy failed in the 1759 naval battles at Lagos and Quiberon Bay. In one piece of good fortune, some French supply ships did manage to depart France and elude the British blockade of the French coast.

1759–1760
The British proceeded to wage a campaign in the northwest frontier of Canada in an effort to cut off the French frontier forts to the west and south. They captured Ticonderoga and Fort Niagara, and they defeated the French at the Thousand Islands in the summer of 1759. In September 1759, James Wolfe defeated Montcalm in the Battle of the Plains of Abraham which claimed the lives of both commanders. After the battle, the French capitulated the city to the British.

In April 1760, François Gaston de Lévis led French forces to launch an attack to retake Quebec. Although he won the Battle of Sainte-Foy, Lévis' subsequent siege of Quebec ended in defeat when British ships arrived to relieve the garrison. After Lévis had retreated he was given another blow when a British naval victory at Restigouche brought the loss of French ships meant to resupply his army. In July Jeffrey Amherst then led British forces numbering around 18,000 men in a three pronged attack on Montreal. After eliminating French positions along the way all three forces met up and surrounded Montreal in September. Many Canadians deserted or surrendered their arms to British forces while the Native allies of the French sought peace and neutrality. De Lévis and the Marquis de Vaudreuil reluctantly signed the Articles of Capitulation of Montreal on September 8 which effectively completed the British conquest of New France.

Sporadic engagements, 1760–1763
Most of the fighting ended in America in 1760, although it continued in Europe between France and Britain. The notable exception was the French seizure of St. John's, Newfoundland. General Amherst heard of this surprise action and immediately dispatched troops under his nephew William Amherst, who regained control of Newfoundland after the Battle of Signal Hill in September 1762. Many of the British troops who were stationed in America were reassigned to participate in further British actions in the West Indies, including the capture of Spanish Havana when Spain belatedly entered the conflict on the side of France, and a British expedition against French Martinique in 1762 led by Major General Robert Monckton.

Peace
Governor Vaudreuil in Montreal negotiated a capitulation with General Amherst in September 1760. Amherst granted his requests that any French residents who chose to remain in the colony would be given freedom to continue worshiping in their Roman Catholic tradition, to own property, and to remain undisturbed in their homes. The British provided medical treatment for the sick and wounded French soldiers, and French regular troops were returned to France aboard British ships with an agreement that they were not to serve again in the present war.

General Amherst also oversaw the transfer of French fortifications to British control on the western frontier. The policies which he introduced in those lands disturbed large numbers of Natives and contributed to the outbreak of Pontiac's War in 1763, in which a series of Native attacks on frontier forts occurred, such as that on Fort Miami which effectively brought a nearly half-century long period of European garrisoning at Kekionga to an end. The frontier settlements required the continued deployment of British forces, and the conflict was not fully concluded until 1766.

Beginning from the 1750s and lasting until the 1760s, a smallpox outbreak devastated several Native communities throughout the American Midwest. The outbreak was brought on in part by victorious Native warriors who had fought on the side of the French bringing home prizes of war which had been infected with the disease; the Ojibwe, Odawa and Potawatomi peoples were most affected by the outbreak. An oral account from Odawa tribal leader and historian Andrew Blackbird claimed that the outbreak had "entirely depopulated and laid waste" to Waganagisi, a large Odawa settlement.

The war in North America, along with the global Seven Years' War, officially ended with the signing of the Treaty of Paris on 10 February 1763, by the kingdoms of Great Britain, France and Spain, with Portugal in agreement. The British offered France the choice of surrendering either its continental North American possessions east of the Mississippi or the Caribbean islands of Guadeloupe and Martinique, which had been occupied by the British. France chose to cede the former but was able to negotiate the retention of Saint Pierre and Miquelon, two small islands in the Gulf of St. Lawrence, along with fishing rights in the area. They viewed the economic value of the Caribbean islands' sugar cane to be greater and easier to defend than the furs from the continent. French philosopher Voltaire referred to Canada disparagingly as nothing more than a few acres of snow. The British, however, were happy to take New France, as defence of their North American colonies would no longer be an issue (though the absence of that threat caused many colonists to conclude they no longer needed British protection). Britain also had ample places from which to obtain sugar. Spain traded Florida to Britain in order to regain Cuba, but they also gained Louisiana from France, including New Orleans, in compensation for their losses. Great Britain and Spain also agreed that navigation on the Mississippi River was to be open to vessels of all nations.

Consequences
The war changed economic, political, governmental, and social relations among the three European powers, their colonies, and the people who inhabited those territories. France and Britain both suffered financially because of the war, with significant long-term consequences.

Britain gained control of French Canada and Acadia, colonies containing approximately 80,000 primarily French-speaking Roman Catholic residents. The deportation of Acadians beginning in 1755 made land available to immigrants from Europe and migrants from the colonies to the south. The British resettled many Acadians throughout its American provinces, but many went to France and some went to New Orleans, which they expected to remain French. Some were sent to colonize places as diverse as French Guiana and the Falkland Islands, but these efforts were unsuccessful. The Louisiana population contributed to founding the Cajun population. (The French word "Acadien" changed to "Cadien" then to "Cajun".)

King George III issued the Royal Proclamation of 1763 on October 7, 1763, which outlined the division and administration of the newly conquered territory, and it continues to govern relations to some extent between the government of Canada and the First Nations. Included in its provisions was the reservation of lands west of the Appalachian Mountains to its Indian population, a demarcation that was only a temporary impediment to a rising tide of westward-bound settlers. The proclamation also contained provisions that prevented civic participation by the Roman Catholic Canadians. The Quebec Act of 1774 addressed issues brought forth by Roman Catholic French Canadians from the 1763 proclamation, and it transferred the Indian Reserve into the Province of Quebec. The Act maintained French Civil law, including the seigneurial system, a medieval code removed from France within a generation by the French Revolution. The Quebec Act was a major concern for the largely Protestant Thirteen Colonies over the advance of "popery". It is typically associated with other Intolerable Acts, legislation that eventually led to the American Revolutionary War. The Quebec Act served as the constitutional document for the Province of Quebec until it was superseded by the Constitutional Act 1791.

The Seven Years' War nearly doubled Great Britain's national debt. The Crown sought sources of revenue to pay it off and attempted to impose new taxes on its colonies. These attempts were met with increasingly stiff resistance, until troops were called in to enforce the Crown's authority, and they ultimately led to the start of the American Revolutionary War. France attached comparatively little value to its American possessions, apart from the highly profitable sugar-producing Antilles islands which it retained. Minister Choiseul considered that he had made a good deal at the Treaty of Paris, and Voltaire wrote that Louis XV had lost a few acres of snow. However, the military defeat and the financial burden of the war weakened the French monarchy and contributed to the advent of the French Revolution in 1789.

The elimination of French power in America meant the disappearance of a strong ally for some Indian tribes. The Ohio Country was now more available to colonial settlement due to the construction of military roads by Braddock and Forbes. The Spanish takeover of the Louisiana territory was not completed until 1769, and it had modest repercussions. The British takeover of Spanish Florida resulted in the westward migration of Indian tribes who did not want to do business with them. This migration also caused a rise in tensions between the Choctaw and the Creek, historic enemies who were competing for land. The change of control in Florida also prompted most of its Spanish Catholic population to leave. Most went to Cuba, although some Christianized Yamasee were resettled to the coast of Mexico.

France returned to America in 1778 with the establishment of a Franco-American alliance against Great Britain in the American Revolutionary War, in what historian Alfred A. Cave describes as French "revenge for Montcalm's death".

Casimir IV Jagiellon

Casimir IV (Casimir Andrew Jagiellon; Kazimierz Andrzej Jagiellończyk ; Lithuanian: ; 30 November 1427 – 7 June 1492) was Grand Duke of Lithuania from 1440 and King of Poland from 1447 until his death in 1492. He was one of the most active Polish-Lithuanian rulers; under him, Poland defeated the Teutonic Knights in the Thirteen Years' War and recovered Pomerania.

The Jagiellonian dynasty became one of the leading royal houses in Europe. The great triumph of his reign was bringing Prussia under Polish rule. The rule of Casimir corresponded to the age of "new monarchies" in western Europe. By the 15th century, Poland had narrowed the distance separating it from Western Europe and became a significant power in international relations. The demand for raw materials and semi-finished goods stimulated trade, producing a positive balance, and contributed to the growth of crafts and mining in the entire country. He was a recipient of the English Order of the Garter (KG), the highest order of chivalry and the most prestigious honour in England.

Following Casimir's death in 1492, John I Albert succeeded him as King of Poland, and Alexander Jagiellon was proclaimed Grand Duke of Lithuania.

Youth
Casimir Jagiellon was the third and youngest son of King Władysław II Jagiełło and his fourth wife, Sophia of Halshany. He often relied on his instinct and feelings and had little political knowledge, but shared a great interest in the diplomacy and economic affairs of the country. Throughout Casimir's youth, Bishop Zbigniew Oleśnicki was his mentor and tutor, however, the cleric felt a strong reluctance towards him, believing that he would be an unsuccessful monarch following Władysław's death.

Grand Duke of Lithuania

The sudden death of Sigismund Kęstutaitis left the office of the Grand Duchy of Lithuania empty. The Voivode of Trakai, Jonas Goštautas, and other magnates of Lithuania, supported Casimir as a candidate to the throne. However many Polish noblemen hoped that the thirteen-year-old boy would become a Vice-regent for the Polish King in Lithuania. Casimir was invited by the Lithuanian magnates to Lithuania, and when he arrived in Vilnius in 1440, he was proclaimed as the Grand Duke of Lithuania on 29 June 1440 by the Council of Lords, contrary to the wishes of the Polish noble lords — an act supported and coordinated by Jonas Goštautas. When the news arrived in the Kingdom of Poland concerning the proclamation of Casimir as the Grand Duke of Lithuania, it was met with hostility, even to the point of military threats against Lithuania. Since the young Grand Duke was underage, the supreme control over the Grand Duchy of Lithuania was in the hands of the Lithuanian Council of Lords, presided by Jonas Goštautas. Casimir was taught Lithuanian language and the customs of Lithuania by appointed court officials.

During Casimir's rule the rights of the Lithuanian nobility — dukes, magnates, and boyars (lesser nobles), irrespective of their religion and ethnicity — were put on an equal footing to those of the Polish szlachta. Additionally, Casimir promised to protect the Grand Duchy's borders and not to appoint persons from the Polish Kingdom to the offices of the Grand Duchy. He accepted that decisions on matters concerning the Grand Duchy would not be made without the Council of Lords' consent. He also granted the subject region of Samogitia the right to elect its own elder. Casimir was the first ruler of Lithuania baptized at birth, becoming the first native Roman Catholic Grand Duke.

King of Poland
In 1427, the Polish nobility initiated an anti-Jagiellonian opposition and attempted to have Władysław II Jagiełło's sons Władysław III and Casimir IV Jagiellon declared illegitimate to the Polish throne as they, being sons of a Lithuanian noblewoman Sophia of Halshany, had no blood link to the previous ruling Polish dynasty, the Piasts, however Casimir's father ensured the succession for his sons.

Casimir succeeded his brother Władysław III (killed at the Battle of Varna in 1444) as King of Poland after a three-year interregnum on 25 June 1447. In 1454, he married Elisabeth of Austria, daughter of King Albert II of Germany and Elizabeth of Luxembourg, a descendant of King Casimir III of Poland. Her distant relative was Frederick III, Holy Roman Emperor. The marriage strengthened the ties between the house of Jagiellon and the sovereigns of Hungary-Bohemia and put Casimir at odds with the emperor through internal Habsburg rivalry.

That same year, Casimir was approached by the Prussian Confederation for aid against the Teutonic Order, which he promised, by making the separatist Prussian regions a protectorate of the Polish Kingdom. However, when the insurgent cities rebelled against the Order, it resisted and the Thirteen Years' War (1454–1466) ensued. After a long and expensive war, Casimir and the Prussian Confederation defeated the Teutonic Order. In the Second Peace of Thorn (1466), the Order recognized Polish sovereignty over the seceded western Prussian regions, Royal Prussia, and the Polish crown's overlordship over the remaining Teutonic Monastic State, transformed in 1525 into a duchy, Ducal Prussia.

Elisabeth's only brother Ladislaus, king of Bohemia and Hungary, died in 1457, and after that Casimir and Elisabeth's dynastic interests were directed also towards her brother's kingdoms.

King Casimir IV died on 7 June 1492 in the Old Grodno Castle in the Grand Duchy of Lithuania, which was in a personal union with Poland.

Foreign policy

The intervention of the Roman curia, which hitherto had been hostile to Casimir, was due to the permutations of European politics. The pope was anxious to get rid of the Hussite King of Bohemia, George Podebrad, as the first step towards the formation of a league against the Ottoman Turks. Casimir was to be a leading factor in this combination, and he took advantage of it to procure the election of his son Vladislaus II as the King of Bohemia. But he would not commit himself too far, and his ulterior plans were frustrated by the rivalry of Matthias Corvinus, King of Hungary, who even went so far as to stimulate the Teutonic Order to rise against Casimir. The death of Matthias in 1490 was a great relief to Poland, and Casimir employed the two remaining years of his reign in consolidating his position still further.

In 1490, Casimir's son John Albert was elected the King of Hungary by a party among the Hungarian nobles. He was, however, defeated by his older brother, King Vladislaus II of Bohemia. Casimir, who wanted to secure a separate realm for his sons, proposed John Albert. Most Hungarian barons and prelates preferred Vladislaus because his rule in Bohemia had indicated that he would respect their liberties. Vladislaus was crowned King of Hungary on 18 September 1490 in Székesfehérvár.

Around 1480 Casimir was allied with the Great Horde against Muscovy and Crimea. His failure to support Khan Akhmed at the Great stand on the Ugra River contributed to Russia's gaining its independence from the steppe nomads.

Tomb
Casimir was interred at Wawel Cathedral in Kraków, in a red marble tomb sculpted by Veit Stoss. In 1973 a research team of 12 experts opened the tomb. Shortly afterward, 10 of the team died prematurely. It was subsequently found that the deaths were caused by toxins originating from fungus present in the tomb.
