Genealogy

Genealogy is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography.

The record of genealogical work may be presented as a "genealogy", a "family history", or a "family tree". In the narrow sense, a "genealogy" or a "family tree" traces the descendants of one person, whereas a "family history" traces the ancestors of one person,  but the terms are often used interchangeably. A family history may include additional biographical information, family traditions, and the like.

The pursuit of family history and origins tends to be shaped by several motives, including the desire to carve out a place for one's family in the larger historical picture, a sense of responsibility to preserve the past for future generations, and self-satisfaction in accurate storytelling. Genealogy research is also performed for scholarly or forensic purposes, or to trace legal next of kin to inherit under intestacy laws.

Overview

Amateur genealogists typically pursue their own ancestry and that of their spouses. Professional genealogists may also conduct research for others, publish books on genealogical methods, teach, or produce their own databases. They may work for companies that provide software or produce materials of use to other professionals and to amateurs. Both try to understand not just where and when people lived but also their lifestyles, biographies, and motivations. This often requires—or leads to—knowledge of antiquated laws, old political boundaries, migration trends, and historical socioeconomic or religious conditions.

Genealogists sometimes specialize in a particular group, e.g., a Scottish clan; a particular surname, such as in a one-name study; a small community, e.g., a single village or parish, such as in a one-place study; or a particular, often famous, person. Bloodlines of Salem is an example of a specialized family-history group. It welcomes members who can prove descent from a participant of the Salem Witch Trials or who simply choose to support the group.

Genealogists and family historians often join family history societies, where novices can learn from more experienced researchers. Such societies generally serve a specific geographical area. Their members may also index records to make them more accessible or engage in advocacy and other efforts to preserve public records and cemeteries. Some schools engage students in such projects as a means to reinforce lessons regarding immigration and history. Other benefits include family medical histories for families with serious medical conditions that are hereditary.

The terms "genealogy" and "family history" are often used synonymously, but some entities offer a slight difference in definition. The Society of Genealogists, while also using the terms interchangeably, describes genealogy as the "establishment of a pedigree by extracting evidence, from valid sources, of how one generation is connected to the next" and family history as "a biographical study of a genealogically proven family and of the community and country in which they lived".

Motivation
Individuals conduct genealogical research for a number of reasons.

Personal or medical interest
Private individuals research genealogy out of curiosity about their heritage. This curiosity can be particularly strong among those whose family histories were lost or unknown due to, for example, adoption or separation from family through divorce, death, or other situations. In addition to simply wanting to know more about who they are and where they came from, individuals may research their genealogy to learn about any hereditary diseases in their family history.

There is a growing interest in family history in the media as a result of advertising and television shows sponsored by large genealogy companies, such as Ancestry.com. This, coupled with easier access to online records and the affordability of DNA tests, has both inspired curiosity and allowed those who are curious to easily start investigating their ancestry.

Community or religious obligation
In communitarian societies, one's identity is defined as much by one's kin network as by individual achievement, and the question "Who are you?" would be answered by a description of father, mother, and tribe. New Zealand Māori, for example, learn whakapapa (genealogies) to discover who they are.

Family history plays a part in the practice of some religious belief systems. For example, The Church of Jesus Christ of Latter-day Saints (LDS Church) has a doctrine of baptism for the dead, which necessitates that members of that faith engage in family history research.

In East Asian countries that were historically shaped by Confucianism, many people follow a practice of ancestor worship as well as genealogical record-keeping. Ancestors' names are inscribed on tablets and placed in shrines, where rituals are performed. Genealogies are also recorded in genealogy books. This practice is rooted in the belief that respect for one's family is a foundation for a healthy society.

Establishing identity
Royal families, both historically and in modern times, keep records of their genealogies in order to establish their right to rule and determine who will be the next sovereign. For centuries in various cultures, one's genealogy has been a source of political and social status.

Some countries and indigenous tribes allow individuals to obtain citizenship based on their genealogy. In Ireland and in Greece, for example, an individual can become a citizen if one of their grandparents was born in that country, regardless of their own or their parents' birthplace. In societies such as Australia or the United States, by the 20th century, there was growing pride in the pioneers and nation-builders. Establishing descent from these was, and is, important to lineage societies, such as the Daughters of the American Revolution and The General Society of Mayflower Descendants. Modern family history explores new sources of status, such as celebrating the resilience of families that survived generations of poverty or slavery, or the success of families in integrating across racial or national boundaries. Some family histories even emphasize links to celebrity criminals, such as the bushranger Ned Kelly in Australia.

Legal and forensic research
Lawyers involved in probate cases do genealogy to locate heirs of property.

Detectives may perform genealogical research using DNA evidence to identify victims of homicides or perpetrators of crimes.

Scholarly research
Historians and geneticists may carry out genealogical research to gain a greater understanding of specific topics in their respective fields, and some may employ professional genealogists in connection with specific aspects of their research. They also publish their research in peer-reviewed journals.

The introduction of postgraduate courses in genealogy in recent years has given genealogy more of an academic focus, with the emergence of peer-reviewed journals in this area. Scholarly genealogy is beginning to emerge as a discipline in its own right, with an increasing number of individuals who have obtained genealogical qualifications carrying out research on a diverse range of topics related to genealogy, both within academic institutions and independently.

Discrimination and persecution
In the US, the "one-drop rule" asserted that any person with even one ancestor of black ancestry ("one drop" of "black blood") was considered black. It was codified into the law of some States (e.g. the Racial Integrity Act of 1924) to reinforce racial segregation.

Genealogy was also used in Nazi Germany to determine whether a person was considered a "Jew" or a "Mischling" (Mischling Test), and whether a person was considered as "Aryan" (Ahnenpass).

Pre-modern genealogy
Hereditary emperors, kings and chiefs in several areas have long claimed descent from gods (thus establishing divine legitimacy). Court genealogists have preserved or invented appropriate genealogical pretensions - for example) in Japan, Polynesia, and the Indo-European world from from Scandinavia through ancient Greece to India.

Historically, in Western societies, genealogy focused on the kinship and descent of rulers and nobles, often arguing or demonstrating the legitimacy of claims to wealth and power. Genealogy often overlapped with heraldry, which reflected the ancestry of noble houses in their coats of arms. Modern scholars regard many claimed noble ancestries as fabrications, such as the Anglo-Saxon Chronicle's tracing of the ancestry of several English kings to the god Woden. With the coming of Christianity to northern Europe, Anglo-Saxon royal genealogies extended the kings' lines of ancestry from Woden back to reach the line of Biblical patriarchs: Noah and Adam. (This extension offered the side-benefit of connecting pretentious rulers with the prestigious genealogy of Jesus.)

Modern historians and genealogists may regard manufactured pseudo-genealogies with a degree of scepticism. However, the desire to find ancestral links with prominent figures from a legendary or distant past has persisted. In the United States, for example, it does no harm to establish one's links to ancestors who boarded the Mayflower. And the popularity of the genealogical hypothesis of The Holy Blood and the Holy Grail (1982) demonstrates popular interest in ancient bloodlines, however dubious.

Some family trees have been maintained for considerable periods. The family tree of Confucius has been maintained for over 2,500 years and is listed in the Guinness Book of World Records as the largest extant family tree. The fifth edition of the Confucius Genealogy was printed in 2009 by the Confucius Genealogy Compilation Committee (CGCC).

Modern times
In modern times, genealogy has become more widespread, with commoners as well as nobility researching and maintaining their family trees. Genealogy received a boost in the late 1970s with the television broadcast of Roots: The Saga of an American Family by Alex Haley. His account of his family's descent from the African tribesman Kunta Kinte inspired many others to study their own lines.

With the advent of the Internet, the number of resources readily accessible to genealogists has vastly increased, fostering an explosion of interest in the topic. Genealogy on the internet became increasingly popular starting in the early 2000s. The Internet has become a major source not only of data for genealogists but also of education and communication.

India
Some notable places where traditional genealogy records are kept include Hindu genealogy registers at Haridwar (Uttarakhand), Varanasi and Allahabad (Uttar Pradesh), Kurukshetra (Haryana), Trimbakeshwar (Maharashtra), and Chintpurni (Himachal Pradesh).

United States
Genealogical research in the United States was first systematized in the early 19th century, especially by John Farmer (1789–1838). Before Farmer's efforts, tracing one's genealogy was seen as an attempt by the American colonists to secure a measure of social standing, an aim that was counter to the new republic's egalitarian, future-oriented ideals (as outlined in the Constitution). As Fourth of July celebrations commemorating the Founding Fathers and the heroes of the Revolutionary War became increasingly popular, however, the pursuit of "antiquarianism", which focused on local history, became acceptable as a way to honor the achievements of early Americans. Farmer capitalized on the acceptability of antiquarianism to frame genealogy within the early republic's ideological framework of pride in one's American ancestors. He corresponded with other antiquarians in New England, where antiquarianism and genealogy were well established, and became a coordinator, booster, and contributor to the growing movement. In the 1820s, he and fellow antiquarians began to produce genealogical and antiquarian tracts in earnest, slowly gaining a devoted audience among the American people. Though Farmer died in 1838, his efforts led to the founding in 1845 of the New England Historic Genealogical Society (NEHGS), one of New England's oldest and most prominent organizations dedicated to the preservation of public records. NEHGS publishes the New England Historical and Genealogical Register.

The Genealogical Society of Utah, founded in 1894, later became the Family History Department of the Church of Jesus Christ of Latter-day Saints. The department's research facility, the Family History Library, which Utah.com claims as "the largest genealogical library in the world", was established to assist in tracing family lineages for special religious ceremonies which Latter-day Saints believe will seal family units together for eternity. Latter-day Saints believe that this fulfilled a biblical prophecy stating that the prophet Elijah would return to "turn the heart of the fathers to the children, and the heart of the children to their fathers." There is a network of church-operated Family History Centers all over the United States and around the world, where volunteers assist the public with tracing their ancestors. Brigham Young University offers bachelor's degree, minor, and concentration programs in Family History and is the only school in North America to offer this.

The American Society of Genealogists is the scholarly honorary society of the U.S. genealogical field. Founded by John Insley Coddington, Arthur Adams, and Meredith B. Colket, Jr., in December 1940, its membership is limited to 50 living fellows. ASG has semi-annually published The Genealogist, a scholarly journal of genealogical research, since 1980. Fellows of the American Society of Genealogists, who bear the post-nominal acronym "FASG", have written some of the most notable genealogical materials of the last half-century.

Some of the most notable scholarly American genealogical journals include The American Genealogist, National Genealogical Society Quarterly, The New England Historical and Genealogical Register, The New York Genealogical and Biographical Record, and The Genealogist.

Research process
Genealogical research is a complex process that uses historical records and sometimes genetic analysis to demonstrate kinship. Reliable conclusions are based on the quality of sources (ideally, original records), the information within those sources, (ideally, primary or firsthand information), and the evidence that can be drawn (directly or indirectly), from that information. In many instances, genealogists must skillfully assemble indirect or circumstantial evidence to build a case for identity and kinship. All evidence and conclusions, together with the documentation that supports them, is then assembled to create a cohesive genealogy or family history.

Genealogists begin their research by collecting family documents and stories. This creates a foundation for documentary research, which involves examining and evaluating historical records for evidence about ancestors and other relatives, their kinship ties, and the events that occurred in their lives. As a rule, genealogists begin with the present and work backwards in time. Historical, social, and family context is essential to achieving correct identification of individuals and relationships. Source citation is also important when conducting genealogical research. To keep track of collected material, family group sheets and pedigree charts are used. Formerly handwritten, these can now be generated by genealogical software.

Genetic analysis
Because a person's DNA contains information that has been passed down relatively unchanged from early ancestors, analysis of DNA is sometimes used for genealogical research. Three DNA types are of particular interest. Mitochondrial DNA (mtDNA) is contained in the mitochondria of the egg cell and is passed down from a mother to all of her children, both male and female; however, only females pass it on to their children. Y-DNA is present only in males and is passed down from a father to his sons (direct male line) with only minor mutations occurring over time. Autosomal DNA (atDNA), is found in the 22 non-sex chromosomes (autosomes) and is inherited from both parents; thus, it can uncover relatives from any branch of the family. A genealogical DNA test allows two individuals to find the probability that they are, or are not, related within an estimated number of generations. Individual genetic test results are collected in databases to match people descended from a relatively recent common ancestor. See, for example, the Molecular Genealogy Research Project. Some tests are limited to either the patrilineal or the matrilineal line.

Collaboration
Most genealogy software programs can export information about persons and their relationships in a standardized format called a GEDCOM. In that format, it can be shared with other genealogists, added to databases, or converted into family web sites. Social networking service (SNS) websites allow genealogists to share data and build their family trees online. Members can upload their family trees and contact other family historians to fill in gaps in their research. In addition to the (SNS) websites, there are other resources that encourage genealogists to connect and share information, such as rootsweb.ancestry.com and rsl.rootsweb.ancestry.com.

Volunteerism
Volunteer efforts figure prominently in genealogy. These range from the extremely informal to the highly organized.

On the informal side are the many popular and useful message boards such as Rootschat and mailing lists on particular surnames, regions, and other topics. These forums can be used to try to find relatives, request record lookups, obtain research advice, and much more. Many genealogists participate in loosely organized projects, both online and off. These collaborations take numerous forms. Some projects prepare name indexes for records, such as probate cases, and publish the indexes, either online or off. These indexes can be used as finding aids to locate original records. Other projects transcribe or abstract records. Offering record lookups for particular geographic areas is another common service. Volunteers do record lookups or take photos in their home areas for researchers who are unable to travel.

Those looking for a structured volunteer environment can join one of thousands of genealogical societies worldwide. Most societies have a unique area of focus, such as a particular surname, ethnicity, geographic area, or descendancy from participants in a given historical event. Genealogical societies are almost exclusively staffed by volunteers and may offer a broad range of services, including maintaining libraries for members' use, publishing newsletters, providing research assistance to the public, offering classes or seminars, and organizing record preservation or transcription projects.

Software

Genealogy software is used to collect, store, sort, and display genealogical data. At a minimum, genealogy software accommodates basic information about individuals, including births, marriages, and deaths. Many programs allow for additional biographical information, including occupation, residence, and notes, and most also offer a method for keeping track of the sources for each piece of evidence. Most programs can generate basic kinship charts and reports, allow for the import of digital photographs and the export of data in the GEDCOM format (short for GEnealogical Data COMmunication) so that data can be shared with those using other genealogy software. More advanced features include the ability to restrict the information that is shared, usually by removing information about living people out of privacy concerns; the import of sound files; the generation of family history books, web pages and other publications; the ability to handle same-sex marriages and children born out of wedlock; searching the Internet for data; and the provision of research guidance. Programs may be geared toward a specific religion, with fields relevant to that religion, or to specific nationalities or ethnic groups, with source types relevant for those groups. Online resources involve complex programming and large data bases, such as censuses.

Records and documentation

Genealogists use a wide variety of records in their research. To effectively conduct genealogical research, it is important to understand how the records were created, what information is included in them, and how and where to access them.

List of record types
Records that are used in genealogy research include:
 * Vital records
 * Birth records
 * Death records
 * Marriage and divorce records
 * Adoption records
 * Biographies and biographical profiles (e.g. Who's Who)
 * Cemetery lists
 * Census records
 * Church and Religious records
 * Baptism or christening
 * Brit milah or Baby naming certificates
 * Confirmation
 * Bar or bat mitzvah
 * Marriage
 * Funeral or death
 * Membership
 * City directories and telephone directories
 * Coroner's reports
 * Court records
 * Criminal records
 * Civil records
 * Diaries, personal letters and family Bibles
 * DNA tests
 * Emigration, immigration and naturalization records
 * Hereditary & lineage organization records, e.g. Daughters of the American Revolution records
 * Land and property records, deeds
 * Medical records
 * Military and conscription records
 * Newspaper articles
 * Obituaries
 * Occupational records
 * Oral histories
 * Passports
 * Photographs
 * Poorhouse, workhouse, almshouse, and asylum records
 * School and alumni association records
 * Ship passenger lists
 * Social Security (within the US) and pension records
 * Tax records
 * Tombstones, cemetery records, and funeral home records
 * Voter registration records
 * Wills and probate records

To keep track of their citizens, governments began keeping records of persons who were neither royalty nor nobility. In England and Germany, for example, such record keeping started with parish registers in the 16th century. As more of the population was recorded, there were sufficient records to follow a family. Major life events, such as births, marriages, and deaths, were often documented with a license, permit, or report. Genealogists locate these records in local, regional or national offices or archives and extract information about family relationships and recreate timelines of persons' lives.

In China, India and other Asian countries, genealogy books are used to record the names, occupations, and other information about family members, with some books dating back hundreds or even thousands of years. In the eastern Indian state of Bihar, there is a written tradition of genealogical records among Maithil Brahmins and Karna Kayasthas called "Panjis", dating to the 12th century CE. Even today these records are consulted prior to marriages.

In Ireland, genealogical records were recorded by professional families of senchaidh (historians) until as late as the mid-17th century. Perhaps the most outstanding example of this genre is Leabhar na nGenealach/The Great Book of Irish Genealogies, by Dubhaltach MacFhirbhisigh (d. 1671), published in 2004.

FamilySearch collections
The LDS Church has engaged in large-scale microfilming of records of genealogical value. Its Family History Library in Salt Lake City, Utah, houses over 2 million microfiche and microfilms of genealogically relevant material, which are also available for on-site research at over 4,500 Family History Centers worldwide.

FamilySearch's website includes many resources for genealogists: a FamilyTree database, historical records, digitized family history books, resources and indexing for African American genealogy such as slave and bank records, and a Family History Research Wiki containing research guidance articles.

Indexing ancestral information
Indexing is the process of transcribing parish records, city vital records, and other reports, to a digital database for searching. Volunteers and professionals participate in the indexing process. Since 2006, the microfilm in the FamilySearch granite mountain vault is in the process of being digitally scanned, available online, and eventually indexed.

For example, after the 72-year legal limit for releasing personal information for the United States Census was reached in 2012, genealogical groups cooperated to index the 132 million residents registered in the 1940 United States Census.

Between 2006 and 2012, the FamilySearch indexing effort produced more than 1 billion searchable records.

In 2022, FamilySearch and Ancestry partnered to use Artificial Intelligence (AI) technology to help the process of indexing more records. The process first began with the public release of the 1950 United States Census. The index of the census would at first be created by an AI trained on handwriting in old documents and then reviewed by thousands of volunteers using FamilySearch.

Record loss and preservation
Sometimes genealogical records are destroyed, whether accidentally or on purpose. In order to do thorough research, genealogists keep track of which records have been destroyed so they know when information they need may be missing. Of particular note for North American genealogy is the 1890 United States Census, which was destroyed in a fire in 1921. Although fragments survive, most of the 1890 census no longer exists. Those looking for genealogical information for families that lived in the United States in 1890 must rely on other information to fill that gap.

War is another cause of record destruction. During World War II, many European records were destroyed. Communists in China during the Cultural Revolution and in Korea during the Korean War destroyed genealogy books kept by families.

Often records are destroyed due to accident or neglect. Since genealogical records are often kept on paper and stacked in high-density storage, they are prone to fire, mold, insect damage, and eventual disintegration. Sometimes records of genealogical value are deliberately destroyed by governments or organizations because the records are considered to be unimportant or a privacy risk. Because of this, genealogists often organize efforts to preserve records that are at risk of destruction. FamilySearch has an ongoing program that assesses what useful genealogical records have the most risk of being destroyed, and sends volunteers to digitize such records. In 2017, the government of Sierra Leone asked FamilySearch for help preserving their rapidly deteriorating vital records. FamilySearch has begun digitizing the records and making them available online. The Federation of Genealogical Societies also organized an effort to preserve and digitize United States War of 1812 pension records. In 2010, they began raising funds, which were contribute by genealogists around the United States and matched by Ancestry.com. Their goal was achieved and the process of digitization was able to begin. The digitized records are available for free online.

Types of information
Genealogists who seek to reconstruct the lives of each ancestor consider all historical information to be "genealogical" information. Traditionally, the basic information needed to ensure correct identification of each person are place names, occupations, family names, first names, and dates. However, modern genealogists greatly expand this list, recognizing the need to place this information in its historical context in order to properly evaluate genealogical evidence and distinguish between same-name individuals. A great deal of information is available for British ancestry with growing resources for other ethnic groups.

Family names

Family names are simultaneously one of the most important pieces of genealogical information, and a source of significant confusion for researchers.

In many cultures, the name of a person refers to the family to which they belongs. This is called the family name, surname, or last name. Patronymics are names that identify an individual based on the father's name. For example, Marga Olafsdottir is Marga, daughter of Olaf, and Olaf Thorsson is Olaf, son of Thor. Many cultures used patronymics before surnames were adopted or came into use. The Dutch in New York, for example, used the patronymic system of names until 1687 when the advent of English rule mandated surname usage. In Iceland, patronymics are used by a majority of the population. In Denmark and Norway patronymics and farm names were generally in use through the 19th century and beyond, though surnames began to come into fashion toward the end of the 19th century in some parts of the country. Not until 1856 in Denmark and 1923 in Norway were there laws requiring surnames.

The transmission of names across generations, marriages and other relationships, and immigration may cause difficulty in genealogical research. For instance, women in many cultures have routinely used their spouse's surnames. When a woman remarried, she may have changed her name and the names of her children; only her name; or changed no names. Her birth name (maiden name) may be reflected in her children's middle names; her own middle name; or dropped entirely. Children may sometimes assume stepparent, foster parent, or adoptive parent names. Because official records may reflect many kinds of surname change, without explaining the underlying reason for the change, the correct identification of a person recorded identified with more than one name is challenging. Immigrants to America often Americanized their names.

Surname data may be found in trade directories, census returns, birth, death, and marriage records.

Given names
Genealogical data regarding given names (first names) is subject to many of the same problems as are family names and place names. Additionally, the use of nicknames is very common. For example, Beth, Lizzie or Betty are all common for Elizabeth, and Jack, John and Jonathan may be interchanged.

Middle names provide additional information. Middle names may be inherited, follow naming customs, or be treated as part of the family name. For instance, in some Latin cultures, both the mother's family name and the father's family name are used by the children.

Historically, naming traditions existed in some places and cultures. Even in areas that tended to use naming conventions, however, they were by no means universal. Families may have used them some of the time, among some of their children, or not at all. A pattern might also be broken to name a newborn after a recently deceased sibling, aunt or uncle.

An example of a naming tradition from England, Scotland and Ireland:

Another example is in some areas of Germany, where siblings were given the same first name, often of a favourite saint or local nobility, but different second names by which they were known (Rufname). If a child died, the next child of the same gender that was born may have been given the same name. It is not uncommon that a list of a particular couple's children will show one or two names repeated.

Personal names have periods of popularity, so it is not uncommon to find many similarly named people in a generation, and even similarly named families; e.g., "William and Mary and their children David, Mary, and John".

Many names may be identified strongly with a particular gender; e.g., William for boys, and Mary for girls. Others may be ambiguous, e.g., Lee, or have only slightly variant spellings based on gender, e.g., Frances (usually female) and Francis (usually male).

Place names
While the locations of ancestors' residences and life events are core elements of the genealogist's quest, they can often be confusing. Place names may be subject to variant spellings by partially literate scribes. Locations may have identical or very similar names. For example, the village name Brockton occurs six times in the border area between the English counties of Shropshire and Staffordshire. Shifts in political borders must also be understood. Parish, county, and national borders have frequently been modified. Old records may contain references to farms and villages that have ceased to exist. When working with older records from Poland, where borders and place names have changed frequently in past centuries, a source with maps and sample records such as A Translation Guide to 19th-Century Polish-Language Civil-Registration Documents can be invaluable.

Available sources may include vital records (civil or church registration), censuses, and tax assessments. Oral tradition is also an important source, although it must be used with caution. When no source information is available for a location, circumstantial evidence may provide a probable answer based on a person's or a family's place of residence at the time of the event.

Maps and gazetteers are important sources for understanding the places researched. They show the relationship of an area to neighboring communities and may be of help in understanding migration patterns. Family tree mapping using online mapping tools such as Google Earth (particularly when used with Historical Map overlays such as those from the David Rumsey Historical Map Collection) assist in the process of understanding the significance of geographical locations.

Dates
It is wise to exercise extreme caution with dates. Dates are more difficult to recall years after an event, and are more easily mistranscribed than other types of genealogical data. Therefore, one should determine whether the date was recorded at the time of the event or at a later date. Dates of birth in vital records or civil registrations and in church records at baptism are generally accurate because they were usually recorded near the time of the event. Family Bibles are often a source for dates, but can be written from memory long after the event. When the same ink and handwriting is used for all entries, the dates were probably written at the same time and therefore will be less reliable since the earlier dates were probably recorded well after the event. The publication date of the Bible also provides a clue about when the dates were recorded since they could not have been recorded at any earlier date.

People sometimes reduce their age on marriage, and those under "full age" may increase their age in order to marry or to join the armed forces. Census returns are notoriously unreliable for ages or for assuming an approximate death date. Ages over 15 in the 1841 census in the UK are rounded down to the next lower multiple of five years.

Although baptismal dates are often used to approximate birth dates, some families waited years before baptizing children, and adult baptisms are the norm in some religions. Both birth and marriage dates may have been adjusted to cover for pre-wedding pregnancies.

Calendar changes must also be considered. In 1752, England and her American colonies changed from the Julian to the Gregorian calendar. In the same year, the date the new year began was changed. Prior to 1752 it was 25 March; this was changed to 1 January. Many other European countries had already made the calendar changes before England had, sometimes centuries earlier. By 1751 there was an 11-day discrepancy between the date in England and the date in other European countries.

For further detail on the changes involved in moving from the Julian to the Gregorian calendar, see: Gregorian calendar.

The French Republican Calendar or French Revolutionary Calendar was a calendar proposed during the French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days in 1871 in Paris. Dates in official records at this time use the revolutionary calendar and need "translating" into the Gregorian calendar for calculating ages etc. There are various websites which do this.

Occupations
Occupational information may be important to understanding an ancestor's life and for distinguishing two people with the same name. A person's occupation may have been related to his or her social status, political interest, and migration pattern. Since skilled trades are often passed from father to son, occupation may also be indirect evidence of a family relationship.

It is important to remember that a person may change occupations, and that titles change over time as well. Some workers no longer fit for their primary trade often took less prestigious jobs later in life, while others moved upwards in prestige. Many unskilled ancestors had a variety of jobs depending on the season and local trade requirements. Census returns may contain some embellishment; e.g., from labourer to mason, or from journeyman to master craftsman. Names for old or unfamiliar local occupations may cause confusion if poorly legible. For example, an ostler (a keeper of horses) and a hostler (an innkeeper) could easily be confused for one another. Likewise, descriptions of such occupations may also be problematic. The perplexing description "ironer of rabbit burrows" may turn out to describe an ironer (profession) in the Bristol district named Rabbit Burrows. Several trades have regionally preferred terms. For example, "shoemaker" and "cordwainer" have the same meaning. Finally, many apparently obscure jobs are part of a larger trade community, such as watchmaking, framework knitting or gunmaking.

Occupational data may be reported in occupational licences, tax assessments, membership records of professional organizations, trade directories, census returns, and vital records (civil registration). Occupational dictionaries are available to explain many obscure and archaic trades.

Reliability of sources
Information found in historical or genealogical sources can be unreliable and it is good practice to evaluate all sources with a critical eye. Factors influencing the reliability of genealogical information include: the knowledge of the informant (or writer); the bias and mental state of the informant (or writer); the passage of time and the potential for copying and compiling errors.

The quality of census data has been of special interest to historians, who have investigated reliability issues.

Knowledge of the informant
The informant is the individual who provided the recorded information. Genealogists must carefully consider who provided the information and what they knew. In many cases the informant is identified in the record itself. For example, a death certificate usually has two informants: a physician who provides information about the time and cause of death and a family member who provides the birth date, names of parents, etc.

When the informant is not identified, one can sometimes deduce information about the identity of the person by careful examination of the source. One should first consider who was alive (and nearby) when the record was created. When the informant is also the person recording the information, the handwriting can be compared to other handwriting samples.

When a source does not provide clues about the informant, genealogists should treat the source with caution. These sources can be useful if they can be compared with independent sources. For example, a census record by itself cannot be given much weight because the informant is unknown. However, when censuses for several years concur on a piece of information that would not likely be guessed by a neighbor, it is likely that the information in these censuses was provided by a family member or other informed person. On the other hand, information in a single census cannot be confirmed by information in an undocumented compiled genealogy since the genealogy may have used the census record as its source and might therefore be dependent on the same misinformed individual.

Motivation of the informant
Even individuals who had knowledge of the fact, sometimes intentionally or unintentionally provided false or misleading information. A person may have lied in order to obtain a government benefit (such as a military pension), avoid taxation, or cover up an embarrassing situation (such as the existence of a non-marital child). A person with a distressed state of mind may not be able to accurately recall information. Many genealogical records were recorded at the time of a loved one's death, and so genealogists should consider the effect that grief may have had on the informant of these records.

The effect of time
The passage of time often affects a person's ability to recall information. Therefore, as a general rule, data recorded soon after the event are usually more reliable than data recorded many years later. However, some types of data are more difficult to recall after many years than others. One type especially prone to recollection errors is dates. Also the ability to recall is affected by the significance that the event had to the individual. These values may have been affected by cultural or individual preferences.

Copying and compiling errors
Genealogists must consider the effects that copying and compiling errors may have had on the information in a source. For this reason, sources are generally categorized in two categories: original and derivative. An original source is one that is not based on another source. A derivative source is information taken from another source. This distinction is important because each time a source is copied, information about the record may be lost and errors may result from the copyist misreading, mistyping, or miswriting the information. Genealogists should consider the number of times information has been copied and the types of derivation a piece of information has undergone. The types of derivatives include: photocopies, transcriptions, abstracts, translations, extractions, and compilations.

In addition to copying errors, compiled sources (such as published genealogies and online pedigree databases) are susceptible to misidentification errors and incorrect conclusions based on circumstantial evidence. Identity errors usually occur when two or more individuals are assumed to be the same person. Circumstantial or indirect evidence does not explicitly answer a genealogical question, but either may be used with other sources to answer the question, suggest a probable answer, or eliminate certain possibilities. Compilers sometimes draw hasty conclusions from circumstantial evidence without sufficiently examining all available sources, without properly understanding the evidence, and without appropriately indicating the level of uncertainty.

Primary and secondary sources
In genealogical research, information can be obtained from primary or secondary sources. Primary sources are records that were made at the time of the event, for example a death certificate would be a primary source for a person's death date and place. Secondary sources are records that are made days, weeks, months, or even years after an event.

Standards and ethics
Organizations that educate and certify genealogists have established standards and ethical guidelines they instruct genealogists to follow.

Research standards
Genealogy research requires analyzing documents and drawing conclusions based on the evidence provided in the available documents. Genealogists need standards to determine whether or not their evaluation of the evidence is accurate. In the past, genealogists in the United States borrowed terms from judicial law to examine evidence found in documents and how they relate to the researcher's conclusions. However, the differences between the two disciplines created a need for genealogists to develop their own standards. In 2000, the Board for Certification of Genealogists published their first manual of standards. The Genealogical Proof Standard created by the Board for Certification of Genealogists is widely distributed in seminars, workshops, and educational materials for genealogists in the United States. Other genealogical organizations around the world have created similar standards they invite genealogists to follow. Such standards provide guidelines for genealogists to evaluate their own research as well as the research of others.

Standards for genealogical research include:
 * Clearly document and organize findings.
 * Cite all sources in a specific manner so that others can locate them and properly evaluate them.
 * Locate all available sources that may contain information relevant to the research question.
 * Analyze findings thoroughly, without ignoring conflicts in records or negative evidence.
 * Rely on original, rather than derivative sources, wherever possible.
 * Use logical reasoning based on reliable sources to reach conclusions.
 * Acknowledge when a specific conclusion is only "possible" or "probable" rather than "proven".
 * Acknowledge that other records that have not yet been discovered may overturn a conclusion.

Ethical guidelines
Genealogists often handle sensitive information and share and publish such information. Because of this, there is a need for ethical standards and boundaries for when information is too sensitive to be published. Historically, some genealogists have fabricated information or have otherwise been untrustworthy. Genealogical organizations around the world have outlined ethical standards as an attempt to eliminate such problems. Ethical standards adopted by various genealogical organizations include: In 2015, a committee presented standards for genetic genealogy at the Salt Lake Institute of Genealogy. The standards emphasize that genealogists and testing companies should respect the privacy of clients and recognize the limits of DNA tests. It also discusses how genealogists should thoroughly document conclusions made using DNA evidence. In 2019, the Board for the Certification of Genealogists officially updated their standards and code of ethics to include standards for genetic genealogy.
 * Respect copyright laws
 * Acknowledge where one consulted another's work and do not plagiarize the work of other researchers.
 * Treat original records with respect and avoid causing damage to them or removing them from repositories.
 * Treat archives and archive staff with respect.
 * Protect the privacy of living individuals by not publishing or otherwise disclosing information about them without their permission.
 * Disclose any conflicts of interest to clients.
 * When doing paid research, be clear with the client about scope of research and fees involved.
 * Do not fabricate information or publish false or unproven information as proven.
 * Be sensitive about information found through genealogical research that may make the client or family members uncomfortable.

Gabon

Gabon, officially the Gabonese Republic (République gabonaise), is a country on the Atlantic coast of Central Africa, on the equator, bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of 270000 sqkm and a population of million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Libreville is the country's capital and largest city.

Gabon's original inhabitants were the pygmy peoples. Beginning in the 14th century, Bantu migrants began settling in the area as well. Since its independence from France in 1960, Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. Despite this, the Gabonese Democratic Party (PDG) remained the dominant party until its removal from the 2023 Gabonese coup d'état.

Gabon is a developing country, ranking 112th in the Human Development Index. It is one of the wealthiest countries in Africa in terms of per capita income; however, large parts of the population are very poor. Omar Bongo came to office in 1967 and created a dynasty, which stabilized its power through a clientist network, Françafrique.

The official language of Gabon is French, and Bantu ethnic groups constitute around 95% of the country's population. Christianity is the nation's predominant religion, practised by about 80% of the population. With petroleum and foreign private investment, it has the fourth highest HDI (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita (PPP) (after Seychelles, Mauritius, Equatorial Guinea and Botswana) of any African nation. Gabon's nominal GDP per capita is $10,149 in 2023 according to OPEC.

Pre-colonisation
Pygmy peoples in the area were largely replaced and absorbed by Bantu tribes as they migrated. By the 18th century, a Myeni-speaking kingdom known as the Kingdom of Orungu formed as a trading centre with the ability to purchase and sell slaves, and fell with the demise of the slave trade in the 1870s.

French rule and independence
Explorer Pierre Savorgnan de Brazza led his first mission to the Gabon-Congo area in 1875. He founded the town of Franceville and was later colonial governor. Some Bantu groups lived in the area when France officially occupied it in 1885.

In 1910, Gabon became a territory of French Equatorial Africa, a federation that survived until 1958. In World War II, the Allies invaded Gabon in order to overthrow the pro-Vichy France colonial administration. On 28 November 1958, Gabon became an autonomous republic within the French Community, and on 17 August 1960, it became fully independent.

M'ba rule
The first president of Gabon, elected in 1961, was Léon M'ba, with Omar Bongo Ondimba as his vice president. After M'ba's accession to power, the press was suppressed, political demonstrations suppressed, freedom of expression curtailed, other political parties gradually excluded from power, and the Constitution changed along French lines to vest power in the Presidency, a post that M'ba assumed himself. When M'ba dissolved the National Assembly in January 1964 to institute one-party rule, an army coup sought to oust him from power and restore parliamentary democracy. French paratroopers flew in within 24 hours to restore M'ba to power. After days of fighting, the coup ended and the opposition was imprisoned, with protests and riots.

Bongo rule and PDG
When M'Ba died in 1967, Bongo replaced him as president. In March 1968, Bongo declared Gabon a 1-party state by dissolving BDG and establishing a new party – the Parti Démocratique Gabonais (PDG). He invited all Gabonese, regardless of previous political affiliation, to participate. Bongo sought to forge a single national movement in support of the government's development policies, using PDG as a tool to submerge the regional and tribal rivalries that had divided Gabonese politics in the past. Bongo was elected president in February 1975; in April 1975, the position of vice president was abolished and replaced by the position of prime minister, who had no right to automatic succession. Bongo was re-elected President in December 1979 and November 1986 to 7-year terms.

In 1990, economic discontent and a desire for political liberalization provoked demonstrations and strikes by students and workers. In response to grievances by workers, Bongo negotiated with them on a sector-by-sector basis, making wage concessions. He promised to open up PDG and to organize a national political conference in March–April 1990 to discuss Gabon's future political system. PDG and 74 political organizations attended the conference. Participants essentially divided into 2 "loose" coalitions, ruling PDG and its allies, and the United Front of Opposition Associations and Parties, consisting of the breakaway Morena Fundamental and the Gabonese Progress Party.

Transitional government and RSDG
The April 1990 conference approved political reforms, including creation of a national Senate, decentralization of the budgetary process, freedom of assembly and press, and cancellation of an exit visa requirement. In an attempt to guide the political system's transformation to multiparty democracy, Bongo resigned as PDG chairman and created a transitional government headed by a new Prime Minister, Casimir Oye-Mba. The Gabonese Social Democratic Grouping (RSDG), as the resulting government was called, was smaller than the previous government and included representatives from some opposition parties in its cabinet. RSDG drafted a provisional constitution in May 1990 that provided a basic bill of rights and an independent judiciary and retained "strong" executive powers for the president. After further review by a constitutional committee and the National Assembly, this document came into force in March 1991.

Opposition to PDG continued after the April 1990 conference, and in September 1990, two coup d'état attempts were uncovered and aborted. With demonstrations after the death of an opposition leader, the first multiparty National Assembly elections in almost 30 years took place in September–October 1990, with PDG garnering a majority.

Bongo's re-election and rule

Following President Omar Bongo's re-election in December 1993 with 51% of the vote, opposition candidates refused to validate the election results. Civil disturbances and violent repression led to an agreement between the government and opposition factions to work toward a political settlement. These talks led to the Paris Accords in November 1994, under which some opposition figures were included in a government of national unity. This arrangement broke down and the 1996 and 1997 legislative and municipal elections provided the background for renewed partisan politics. PDG won in the legislative election, and some cities, including Libreville, elected opposition mayors during the 1997 local election.

Boycott of elections and crisis
Facing a divided opposition, President Omar Bongo coasted to re-election in December 1998. While some of Bongo's opponents rejected the outcome as fraudulent, some international observers characterized the results as representative "despite many perceived irregularities". Legislative elections held in 2001–2002 were boycotted by a number of smaller opposition parties and were criticized for their administrative weaknesses, produced a National Assembly dominated by PDG and allied independents. In November 2005 President Omar Bongo was elected for his sixth term. He won re-election, and opponents claim that the balloting process was marred by irregularities. There were some instances of violence following the announcement of his win. National Assembly elections were held in December 2006. Some seats contested because of voting irregularities were overturned by the Constitutional Court, and the subsequent run-off elections in 2007 yielded a PDG-controlled National Assembly.

Death of Bongo and succession

Following the passing of President Omar Bongo on 8 June 2009 due to cardiac arrest at a Spanish hospital in Barcelona, Gabon entered a period of political transition. Per the amended constitution, Rose Francine Rogombé, the President of the Senate, assumed the role of Interim President on 10 June 2009. The subsequent presidential elections, held on 30 August 2009, marked a historic moment as they were the first in Gabon's history not to feature Omar Bongo as a candidate. With a crowded field of 18 contenders, including Omar Bongo's son and ruling party leader, Ali Bongo, the elections were closely watched both domestically and internationally.

After a rigorous three-week review by the Constitutional Court, Ali Bongo was officially declared the winner, leading to his inauguration on 16 October 2009. However, the announcement of his victory was met with skepticism by some opposition candidates, sparking sporadic protests across the country. Nowhere was this discontent more pronounced than in Port-Gentil, where allegations of electoral fraud resulted in violent demonstrations. The unrest claimed four lives and led to significant property damage, including attacks on the French Consulate and a local prison. Subsequently, security forces were deployed, and a curfew remained in effect for over three months.

In June 2010, a partial legislative by-election was held, marking the emergence of the Union Nationale (UN) coalition, primarily comprising defectors from the ruling PDG party following Omar Bongo's passing. The contest for the five available seats saw both the PDG and UN claiming victory, underscoring the political tensions that persisted in the aftermath of the presidential transition.

The political landscape was further disrupted in January 2019 when a group of soldiers attempted a coup against President Ali Bongo. Despite initial unrest, the coup ultimately failed, but it highlighted the ongoing challenges facing Gabon's political stability.

Against this backdrop of political volatility, Gabon achieved significant milestones on the international stage. In June 2021, it became the first country to receive payments for reducing emissions resulting from deforestation and forest degradation. Additionally, in June 2022, Gabon, along with Togo, joined the Commonwealth of Nations, signalling its commitment to multilateral engagement and cooperation.

2023 coup d'état
In August 2023, following the announcement that Ali Bongo had won a third term in the general election, military officers announced that they had taken power in a coup d'état and cancelled the election results. They also dissolved state institutions including the Judiciary, Parliament and the constitutional assembly. On 31 August 2023, army officers who seized power, ending the Bongo family's 55-year hold on power, named Gen Brice Oligui Nguema as the country's transitional leader. On 4 September 2023, General Nguema was sworn in as interim president of Gabon.

Politics
The presidential republic form of government is stated under the 1961 constitution (revised in 1975, rewritten in 1991, and revised in 2003). The president is elected by universal suffrage for a seven-year term; a 2003 constitutional amendment removed presidential term limits. The president can appoint and dismiss the prime minister, the cabinet, and judges of the independent Supreme Court. The president has other powers such as authority to dissolve the National Assembly, declare a state of siege, delay legislation, and conduct referendums. Gabon has a bicameral legislature with a National Assembly and Senate. The National Assembly has 120 deputies who are popularly elected for a five-year term. The Senate is composed of 102 members who are elected by municipal councils and regional assemblies and serve for six years. The Senate was created in the 1990–1991 constitutional revision, and was not brought into being until after the 1997 local elections. The President of the Senate is next in succession to the President.

In 1990, the government made changes to Gabon's political system. A transitional constitution was drafted in May 1990 as an outgrowth of the national political conference in March–April and later revised by a constitutional committee. Among its provisions were a Western-style bill of rights, creation of a National Council of Democracy to oversee the guarantee of those rights, a governmental advisory board on economic and social issues, and an independent judiciary. After approval by the National Assembly, PDG Central Committee, and the President, the Assembly unanimously adopted the constitution in March 1991. Multiparty legislative elections were held in 1990–1991 when opposition parties had not been declared formally legal. In January 1991, the Assembly passed by unanimous vote a law governing the legalization of opposition parties.

After President Omar Bongo was re-elected in 1993, in a disputed election where only 51% of votes were cast, social and political disturbances led to the 1994 Paris Conference and Accords. These provided a framework for the next elections. Local and legislative elections were delayed until 1996–1997. In 1997, constitutional amendments put forward years earlier were adopted to create the Senate and the position of Vice President, and to extend the President's term to seven years.

In October 2009, President Ali Bongo Ondimba began efforts to streamline the government. In an effort to reduce corruption and government bloat, he eliminated 17 minister-level positions, abolished the Vice Presidency and reorganized the portfolios of some ministries, bureaus and directorates. In November 2009, President Bongo Ondimba announced a new vision for the modernization of Gabon, called "Gabon Emergent". This program contains three pillars: Green Gabon, Service Gabon, and Industrial Gabon. The goals of Gabon Emergent are to diversify the economy so that Gabon becomes less reliant on petroleum, to eliminate corruption, and to modernize the workforce. Under this program, exports of raw timber have been banned, a government-wide census was held, the work day was changed to eliminate a long midday break, and a national oil company was created.

On 25 January 2011, opposition leader André Mba Obame claimed the presidency, saying the country should be run by someone the people really wanted. He selected 19 ministers for his government, and the entire group, along with hundreds of others, spent the night at the United Nations headquarters. On January 26, the government dissolved Mba Obame's party. AU chairman Jean Ping said that Mba Obame's action "hurts the integrity of legitimate institutions and also endangers the peace, the security and the stability of Gabon." Interior Minister Jean-François Ndongou accused Mba Obame and his supporters of treason. The UN Secretary-General, Ban Ki-moon, said that he recognized Ondimba as the only official Gabonese president.

The 2016 presidential election was disputed, with "very close" official results reported. Protests broke out in the capital and met a repression which culminated in the alleged bombing of opposition party headquarters by the presidential guard. Between 50 and 100 citizens were killed by security forces and 1,000 arrested. International observers criticized irregularities, including unnaturally high turnout reported for some districts. The country's supreme court threw out some suspect precincts, and the ballots have been destroyed. The election was declared in favour of the incumbent Ondimba. The European Parliament issued two resolutions denouncing the unclear results of the election and calling for an investigation on the human rights violations.

A few days after the controversial presidential election in August 2023, a group of military officials declared a military coup and that they had overthrown the government and deposed Ali Bongo Ondimba. The announcement came hours after Ali Bongo was officially re-elected for a third term. General Brice Oligui Nguema was appointed as the transitional leader. This event marked the eighth instance of military intervention in the region since 2020, raising concerns about democratic stability.

Foreign relations
Since independence, Gabon has followed a nonaligned policy, advocating dialogue in international affairs and recognizing each side of divided countries. In intra-African affairs, it espouses development by evolution rather than revolution and favours regulated private enterprise as the system most likely to promote rapid economic growth. It involved itself in mediation efforts in Chad, the Central African Republic, Angola, the Republic of the Congo, the Democratic Republic of the Congo (D.R.C.), and Burundi. In December 1999, through the mediation efforts of President Bongo, a peace accord was signed in the Republic of the Congo (Brazzaville) between the government and most leaders of an armed rebellion. President Bongo was involved in the continuing D.R.C. peace process, and played a role in mediating the crisis in Ivory Coast.

Gabon is a member of the United Nations (UN) and some of its specialized and related agencies, and of the World Bank; the IMF; the African Union (AU); the Central African Customs Union/Central African Economic and Monetary Community (UDEAC/CEMAC); EU/ACP association under the Lomé Convention; the Communaute Financiere Africaine (CFA); the Organization of the Islamic Conference (OIC); the Nonaligned Movement; and the Economic Community of Central African States (ECCAS/CEEAC). In 1995, Gabon withdrew from the Organization of the Petroleum Exporting Countries (OPEC), rejoining in 2016. Gabon was elected to a non-permanent seat on the United Nations Security Council for January 2010 through December 2011 and held the rotating presidency in March 2010. In 2022, Gabon joined the Commonwealth of Nations. In 2024, ruling junta leader Brice Oligui Nguema assured American and French leaders that Gabon would be an ally of the West moving forward, as a part of his broader plan to solve the ongoing debt crisis.

Military
It has a professional military of about 5,000 personnel, divided into army, navy, air force, gendarmerie, and police force. A 1,800-member guard provides security for the president.

Administrative divisions
It is divided into 9 provinces which are subdivided into 50 departments. The president appoints the provincial governors, the prefects, and the subprefects.

The provinces are (capitals in parentheses):
 * 1) Estuaire (Libreville)
 * 2) Haut-Ogooué (Franceville)
 * 3) Moyen-Ogooué (Lambaréné)
 * 4) Ngounié (Mouila)
 * 5) Nyanga (Tchibanga)
 * 6) Ogooué-Ivindo (Makokou)
 * 7) Ogooué-Lolo (Koulamoutou)
 * 8) Ogooué-Maritime (Port-Gentil)
 * 9) Woleu-Ntem (Oyem)

Geography
Gabon is located on the Atlantic coast of central Africa on the equator, between latitudes 3°N and 4°S, and longitudes 8° and 15°E. Gabon has an equatorial climate with a system of rainforests, with 89.3% of its land area forested.

There are coastal plains (ranging between 20 and 300 km from the ocean's shore), the mountains (the Cristal Mountains to the northeast of Libreville, the Chaillu Massif in the centre), and the savanna in the east. The coastal plains form a section of the World Wildlife Fund's Atlantic Equatorial coastal forests ecoregion and contain patches of Central African mangroves including on the Muni River estuary on the border with Equatorial Guinea.

Geologically, Gabon is primarily Archaean and Palaeoproterozoic igneous and metamorphic basement rock, belonging to the stable continental crust of the Congo Craton. Some formations are more than 2 billion years old. Some rock units are overlain by marine carbonate, lacustrine and continental sedimentary rocks, and unconsolidated sediments and soils that formed in the last 2.5 million years of the Quaternary. The rifting apart of the supercontinent Pangaea created rift basins that filled with sediments and formed the hydrocarbons. There are Oklo reactor zones, a natural nuclear fission reactor on Earth which was active 2 billion years ago. The site was discovered during uranium mining in the 1970s to supply the French nuclear power industry.

Its largest river is the Ogooué which is 1200 km long. It has 3 karst areas where there are hundreds of caves located in the dolomite and limestone rocks. A National Geographic Expedition visited some caves in the summer of 2008 to document them.

In 2002, President Omar Bongo Ondimba designated roughly 10% of the nation's territory to be part of its national park system (with 13 parks in total). The National Agency for National Parks manages Gabon's national park system. Gabon had a 2018 Forest Landscape Integrity Index mean score of 9.07/10, ranking it 9th globally out of 172 countries.

Wildlife
Gabon has a large number of protected animal and plant species. The country's biodiversity is one of the most varied on the planet.

Fauna of Gabon
Gabon is home of 604 species of birds, 98 species of amphibians, between 95 and 160 species of reptiles and 198 different species of mammals. In Gabon there are rare species, such as the Gabon pangolin and the grey-necked rockfowl, or endemics, such as the Gabon guenon.

The country is one of the most varied and important fauna reserves in Africa: it is an important refuge for chimpanzees (whose number, in 2003, was estimated between 27,000 and 64,000) and gorillas (28,000-42,000 estimated in 1983). The "Gorilla and Chimpanzee Study Station" inside the Lopé National Park is dedicated to their study.

It is also home to more than half the population of African forest elephants, mostly in Minkébé National Park. Gabon's national symbol is the black panther.

Flora of Gabon
More than 10,000 species of plants, and 400 species of trees form the flora of Gabon. Gabon's rainforest is considered the densest and most virgin in Africa. However, the country's enormous population growth is causing heavy deforestation that threatens this valuable ecosystem. Likewise, poaching endangers wildlife. Gabon's national flower is Delonix Regia.

Economy
Oil revenues constitute roughly 46% of the government's budget, 43% of the gross domestic product (GDP), and 81% of exports. Oil production declined from its higher point of 370,000 barrels per day in 1997. Some estimates suggest that Gabonese oil will be expended by 2025. Planning is beginning for an after-oil scenario. The Grondin Oil Field was discovered in 50 m water depths 40 km offshore, in 1971 and produces from the Batanga sandstones of Maastrichtian age forming an anticline salt structural trap which is about 2 km deep.

As of 2023, Gabon produces about 200,000 barrels a day (bpd) of crude oil.

"Overspending" on the Trans-Gabon Railway, the CFA franc devaluation of 1994, and periods of lower oil prices caused debt problems.

Successive International Monetary Fund (IMF) missions have criticized the Gabonaise government for overspending on off-budget items (in good years and bad), over-borrowing from the central bank, and slipping on the schedule for privatization and administrative reform. In September 2005 Gabon successfully concluded a 15-month Stand-By Arrangement with the IMF. A three-year Stand-By Arrangement with IMF was approved in May 2007. Because of the financial crisis and social developments surrounding the death of President Omar Bongo and the elections, Gabon was unable to meet its economic goals under the Stand-By Arrangement in 2009.

Gabon's oil revenues have given it a per capita GDP of $8,600. A "skewed income distribution" and "poor social indicators" are "evident". The richest 20% of the population earn over 90% of the income while about a third of the Gabonese population lives in poverty.

The economy is dependent on extraction. Before the discovery of oil, logging was the "pillar" of the Gabonese economy. Then, logging and manganese mining are the "next-most-important" income generators. Some explorations suggest the presence of the world's largest unexploited iron ore deposit. For some who live in rural areas without access to employment opportunity in extractive industries, remittances from family members in urban areas or subsistence activities provide income.

Foreign and local observers have lamented the lack of diversity in the Gabonese economy. Factors that have "limited the development of new industries" were listed as follows:
 * the market is "small", about a million
 * dependent on imports from France
 * unable to capitalize on regional markets
 * entrepreneurial zeal not always present among the Gabonese
 * a "fairly regular" stream of oil "rent", even if it is diminishing

Further investment in the agricultural or tourism sectors is "complicated by poor infrastructure". Some processing and service sectors are "largely dominated by a few prominent local investors".

At World Bank and IMF insistence, the government embarked in the 1990s on a program of privatization of its state-owned companies and administrative reform, including reducing public sector employment and salary growth. A government has voiced a commitment to work toward an economic transformation of the country.

Demographics
It has a population of approximately million. Historical and environmental factors caused its population to decline between 1900 and 1940. It has one of the lowest population densities of any country in Africa, and the fourth highest Human Development Index in Sub-Saharan Africa.

Ethnic groups
Gabon has at least 40 ethnic groups, including Fang, Myènè, Punu-Échira, Nzebi-Adouma, Teke-Mbete, Mèmbè, Kota, Akélé. There are indigenous Pygmy peoples: the Bongo, and Baka. The latter speak the only non-Bantu language in Gabon. More than 10,000 native French live in Gabon, including an estimated 2,000 dual nationals.

Some ethnicities are spread throughout Gabon, leading to contact, interaction among the groups, and intermarriage.

Languages
French is the sole official language. It is estimated that 80% of the population can speak French, and that 30% of Libreville residents are native speakers of the language.

Nationally, a majority of the Gabonese people speak indigenous languages, according to their ethnic group, while this proportion is lower than in most other Sub-Saharan African countries. The 2013 census found that 63.7% of Gabon's population could speak a Gabonese language, broken down by 86.3% in rural areas and 60.5% in urban areas speaking at least one national language.

Religion
Religions practised in Gabon include Christianity (Roman Catholicism and Protestantism), Islam, and traditional indigenous religious beliefs. Some people practise elements of both Christianity and indigenous religious beliefs. Approximately 79% of the population (53% Catholic) practise one of the denominations of Christianity; 10% practise Islam (mainly Sunni); the remainder practise other religions.

Health
A private hospital was established in 1913 in Lambaréné by Albert Schweitzer. By 1985 there were 28 hospitals, 87 medical centres, and 312 infirmaries and dispensaries. , there were an estimated 29 physicians per 100,000 people, and "approximately 90% of the population had access to health care services".

In 2000, 70% of the population had access to "safe drinking water" and 21% had "adequate sanitation". A government health program treats such diseases as leprosy, sleeping sickness, malaria, filariasis, intestinal worms, and tuberculosis. Rates for immunization of children under the age of 1 were 97% for tuberculosis and 65% for polio. Immunization rates for DPT and measles were 37% and 56% respectively. Gabon has a domestic supply of pharmaceuticals from a factory in Libreville.

The total fertility rate has decreased from 5.8 in 1960 to 4.2 children per mother during childbearing years in 2000. 10% of all births were "low birth weight". The maternal mortality rate was 520 per 100,000 live births as of 1998. In 2005, the infant mortality rate was 55.35 per 1,000 live births and life expectancy was 55.02 years. As of 2002, the overall mortality rate was estimated at 17.6 per 1,000 inhabitants.

The HIV/AIDS prevalence is estimated to be 5.2% of the adult population (ages 15–49). , approximately 46,000 people were living with HIV/AIDS. There were an estimated 2,400 deaths from AIDS in 2009 – down from 3,000 deaths in 2003.

Education
Its education system is regulated by two ministries: the Ministry of Education, in charge of pre-kindergarten through the last high school grade, and the Ministry of Higher Education and Innovative Technologies, in charge of universities, higher education, and professional schools.

Education is compulsory for children ages 6 to 16 under the Education Act. Some children in Gabon start their school lives by attending nurseries or "Crèche", then kindergarten known as "Jardins d'Enfants". At age 6, they are enrolled in primary school, "École Primaire" which is made up of 6 grades. The next level is "École Secondaire", which is made up of 7 grades. The planned graduation age is 19 years old. Those who graduate can apply for admission at institutions of higher learning, including engineering schools or business schools. As of 2012, the literacy rate of a population ages 15 and above was 82%.

The government has used oil revenue for school construction, paying teachers' salaries, and promoting education, including in rural areas. Maintenance of school structures, and teachers' salaries, has been declining. In 2002 the gross primary enrollment rate was 132%, and in 2000 the net primary enrollment rate was 78%. Gross and net enrollment ratios are based on the number of students formally registered in primary school. As of 2001, 69% of children who started primary school were "likely" to reach grade 5. Problems in the education system include "poor management and planning, lack of oversight, poorly qualified teachers", and "overcrowded classrooms". There are various universities in Gabon which are being chartered, licensed or accredited by the appropriate Gabonese higher education-related organization.

Culture

Gabon's cultural heritage, rooted in an oral tradition for much of its history, began to flourish with the spread of literacy in the 21st century. Rich in folklore and mythology, the country is home to a tapestry of traditions that have been preserved and passed down through generations. Custodians of these traditions, known as "raconteurs," diligently work to ensure their continuity, nurturing practices like the mvett among the Fangs and the Ingwala among the Nzebis.

Central to Gabonese culture are its iconic masks, each imbued with unique significance and craftsmanship. Among these are the renowned n'goltang masks of the Fang people and the intricate reliquary figures of the Kota. These masks hold crucial roles in various ceremonies, including those marking significant life events such as marriage, birth, and funerals. Crafted by traditionalists using rare local woods and other precious materials, these masks serve as artistic expressions and vessels of cultural heritage.

Music
It has an array of folk styles. Imported rock and hip hop from the US and UK are in Gabon, as are rumba, makossa and soukous. Some folk instruments include the obala, the ngombi, the balafon and drums.

Media
Radio-Diffusion Télévision Gabonaise (RTG) which is owned and operated by the government broadcasts in French and indigenous languages. Colour television broadcasts have been introduced in some cities. In 1981, a commercial radio station, Africa No. 1, began operations. It has participation from the French and Gabonese governments and private European media.

In 2004, the government operated 2 radio stations and another 7 were privately owned. There were 2 government television stations and 4 privately owned.

History of Gabon

Little is known of the history of Gabon before European contact. Bantu migrants settled the area beginning in the 14th century. Portuguese explorers and traders arrived in the area in the late 15th century. The coast subsequently became a centre of the transatlantic slave trade with European slave traders arriving to the region in the 16th century. In 1839 and 1841, France established a protectorate over the coast. In 1849, captives released from a captured slave ship founded Libreville. In 1862–1887, France expanded its control including the interior of the state, and took full sovereignty. In 1910 Gabon became part of French Equatorial Africa and in 1960, Gabon became independent.

At the time of Gabon's independence, two principal political parties existed: the Gabonese Democratic Bloc (BDG), led by Léon M'Ba, and the Gabonese Democratic and Social Union (UDSG), led by Jean-Hilaire Aubame. In the first post-independence election, held under a parliamentary system, neither party was able to win a majority; the leaders subsequently agreed against a two-party system and ran with a single list of candidates. In the February 1961 election, held under the new presidential system, M'Ba became president and Aubame became foreign minister. The single-party solution disintegrated in 1963, and there was a single-day bloodless coup in 1964. In March 1967, Leon M'Ba and Omar Bongo were elected president and vice president. M'Ba died later that year. Bongo declared Gabon a one-party state, dissolved the BDG and established the Gabonese Democratic Party (PDG). Sweeping political reforms in 1990 led to a new constitution, and the PDG garnered a large majority in the country's first multi-party elections in 30 years. Despite discontent from opposition parties, Bongo remained president until his death in 2009.

Early history
The societies of the indigenous Pygmies were largely displaced from about AD 1000 onwards by migrating Bantu peoples from the north, such as the Fang. Little is known of tribal life before European contact, but tribal art suggests a rich cultural heritage.

Gabon's first confirmed European visitors were Portuguese explorers and traders who arrived in the late 15th century. At this time, the southern coast was controlled by the Kingdom of Loango. The Portuguese settled on the offshore islands of São Tomé, Príncipe, and Fernando Pó, but were regular visitors to the coast.

They named the Gabon region after the Portuguese word gabão — a coat with sleeve and hood resembling the shape of the Komo River estuary. More European merchants came to the region in the 16th century, trading for slaves, ivory and tropical woods.

French colonial period

In 1838 and 1841, France established a protectorate over the coastal regions of Gabon by treaties with Gabonese coastal chiefs.

American missionaries from New England established a mission at the mouth of the Komo River in 1842. In 1849, the French authorities captured an illegal slave ship and freed the captives on board. The captives were released near the mission station, where they founded a settlement which was called Libreville (French for "free town")

French explorers penetrated Gabon's dense jungles between 1862 and 1887. The most famous, Pierre Savorgnan de Brazza, used Gabonese bearers and guides in his search for the headwaters of the Congo River. France occupied Gabon in 1885, but did not administer it until 1903. Gabon's first political party, the Jeunesse Gabonais, was founded around 1922.

In 1910 Gabon became one of the four territories of French Equatorial Africa. On 15 July 1960 France agreed to Gabon becoming fully independent. On 17 August 1960 Gabon became an independent country.

Independence
At the time of Gabon's independence in 1960, two principal political parties existed: the Gabonese Democratic Bloc (BDG), led by Léon M'Ba, and the Gabonese Democratic and Social Union (UDSG), led by Jean-Hilaire Aubame. In the first post-independence election, held under a parliamentary system, neither party was able to win a majority. The BDG obtained support from three of the four independent legislative deputies, and M'Ba was named Prime Minister. Soon after concluding that Gabon had an insufficient number of people for a two-party system, the two party leaders agreed on a single list of candidates. In the February 1961 election, held under the new presidential system, M'Ba became president and Aubame became foreign minister.

This one-party system appeared to work until February 1963, when the larger BDG element forced the UDSG members to choose between a merger of the parties or resignation. The UDSG cabinet ministers resigned, and M'Ba called an election for February 1964 and a reduced number of National Assembly deputies (from 67 to 47). The UDSG failed to muster a list of candidates able to meet the requirements of the electoral decrees. When the BDG appeared likely to win the election by default, the Gabonese military toppled M'Ba in a bloodless coup on 18 February 1964. French troops re-established his government the next day. Elections were held in April 1964 with many opposition participants. BDG-supported candidates won 31 seats and the opposition 16. Late in 1966, the constitution was revised to provide for automatic succession of the vice president should the president die in office. In March 1967, Leon M'Ba and Omar Bongo (then known as Albert Bongo) were elected President and Vice President, with the BDG winning all 47 seats in the National Assembly. M'Ba died later that year, and Omar Bongo became president.

In March 1968 Bongo declared Gabon a one-party state by dissolving the BDG and establishing a new party: the Gabonese Democratic Party (Parti Démocratique Gabonais) (PDG). He invited all Gabonese, regardless of previous political affiliation, to participate. Bongo was elected President in February 1973; in April 1975, the office of vice president was abolished and replaced by the office of prime minister, who had no right to automatic succession. Bongo was re-elected president in December 1979 and November 1986 to 7-year terms. Using the PDG as a tool to submerge the regional and tribal rivalries that divided Gabonese politics in the past, Bongo sought to forge a single national movement in support of the government's development policies.

Economic discontent and a desire for political liberalization provoked violent demonstrations and strikes by students and workers in early 1990. In response to worker grievances, Bongo negotiated on a sector-by-sector basis, making significant wage concessions. In addition, he promised to open up the PDG and to organize a national political conference in March–April 1990 to discuss Gabon's future political system. The PDG and 74 political organizations attended the conference. Participants essentially divided into two loose coalitions, the ruling PDG and its allies, and the United Front of Opposition Associations and Parties, consisting of the breakaway Morena Fundamental and the Gabonese Progress Party.

The April 1990 conference approved sweeping political reforms, including creation of a national Senate, decentralization of the budgetary process, freedom of assembly and press, and cancellation of the exit visa requirement. In an attempt to guide the political system's transformation to multiparty democracy, Bongo resigned as PDG chairman and created a transitional government headed by a new Prime Minister, Casimir Oyé-Mba. The Gabonese Social Democratic Grouping (RSDG), as the resulting government was called, was smaller than the previous government and included representatives from several opposition parties in its cabinet. The RSDG drafted a provisional constitution in May 1990 that provided a basic bill of rights and an independent judiciary but retained strong executive powers for the president. After further review by a constitutional committee and the National Assembly, this document came into force in March 1991. Under the 1991 constitution, in the event of the president's death, the Prime Minister, the National Assembly president, and the defence minister were to share power until a new election could be held.

Opposition to the PDG continued, however, and in September 1990, two coup d'état attempts were uncovered and aborted. Despite anti-government demonstrations after the untimely death of an opposition leader, the first multiparty National Assembly elections in almost 30 years took place in September–October 1990, with the PDG garnering a large majority.

Following President Bongo's re-election in December 1993 with 51% of the vote, opposition candidates refused to validate the election results. Serious civil disturbances led to an agreement between the government and opposition factions to work toward a political settlement. These talks led to the Paris Accords in November 1994, under which several opposition figures were included in a government of national unity, and constitutional reforms were approved in a referendum in 1995. This arrangement soon broke down, however, and the 1996 and 1997 legislative and municipal elections provided the background for renewed partisan politics. The PDG won a landslide victory in the legislative election, but several major cities, including Libreville, elected opposition mayors during the 1997 local election.

Modern times
President Bongo coasted to easy re-elections in December 1998 and November 2005, with large majorities of the vote against a divided opposition. While Bongo's major opponents rejected the outcome as fraudulent, some international observers characterized the results as representative despite any perceived irregularities. Legislative elections held in 2001–2002, which were boycotted by a number of smaller opposition parties and were widely criticized for their administrative weaknesses, produced a National Assembly almost completely dominated by the PDG and allied independents.

Omar Bongo died at a Spanish hospital on 8 June 2009.

His son Ali Bongo Ondimba was elected president in the August 2009 presidential election. He was re-elected in August 2016, in elections marred by numerous irregularities, arrests, human rights violations and post-election violence.

On 24 October 2018, Ali Bongo Ondimbao was hospitalized in Riyadh for an undisclosed illness. On 29 November 2018 Bongo was transferred to a military hospital in Rabat to continue recovery. On 9 December 2018 it was reported by Gabon's Vice President Moussavou that Bongo suffered a stroke in Riyadh and has since left the hospital in Rabat and is currently recovering at a private residence in Rabat. Since 24 October 2018 Bongo has not been seen in public and due to lack of evidence that he is either alive or dead many have speculated if he is truly alive or not. On 1 January 2019 Bongo gave his first public address via a video posted to social media since falling ill in October 2018 putting to rest any rumours he was dead.

On 7 January 2019, soldiers in Gabon launched an unsuccessful coup d’etat attempt.

On May 11, 2021, a Commonwealth delegation visited Gabon as Ali Bongo visited London to meet with the secretary general of the organization, which brings together 54 English-speaking countries. President Bongo expressed Gabon's willingness to join the Commonwealth. In June 2022, Gabon joined the Commonwealth as its 55th member.

In August 2023, following the announcement that Ali Bongo had won a third term in the general election, military officers announced that they had taken power in a coup d'état and cancelled the election results. They also dissolved state institutions including the Judiciary, Parliament and the constitutional assembly. On 31 August 2023, army officers who seized power, ending the Bongo family's 55-year hold on power, named Gen Brice Oligui Nguema as the country's transitional leader. On 4 September 2023, General Nguema was sworn in as interim president of Gabon.
