Albany County, New York

Albany County is a county in the state of New York, United States. Its northern border is formed by the Mohawk River, at its confluence with the Hudson River, which is to the east. As of the 2020 United States Census, the population was 314,848. The county seat and largest city is Albany, which is also the state capital of New York. As originally established by the English government in the colonial era, Albany County had an indefinite amount of land, but has had an area of 530 sqmi since March 3, 1888. The county is named for the Duke of York and of Albany, who became James II of England (James VII of Scotland). The county is part of the Capital District region of the state.

Colonial
After England took control of the colony of New Netherland from the Dutch, Albany County was created on November 1, 1683, by New York Governor Thomas Dongan, and confirmed on October 1, 1691. The act creating the county vaguely defined its territory "to containe the Towns of Albany, the Collony Rensselaerwyck, Schonecteda, and all the villages, neighborhoods, and Christian Plantaçons on the east side of Hudson River from Roelef's Creek, and on the west side from Sawyer's Creek (Saugerties) to the Sarraghtoga." The confirmation declared in 1691 was similar but omitted the Town of Albany, substituted "Mannor of Ranselaerswyck" for "Collony Rensselaerwyck", and stated "to the uttermost end of Sarraghtoga" instead of just "to Sarraghtoga". Livingston Manor was annexed to Albany County from Dutchess County in 1717.

Albany's boundaries were defined more closely as state statutes would add land to the county, or more commonly subtract land for the formation of new counties. In 1772 with the creation of Tryon and Charlotte counties, Albany gained definitive boundaries and included what are now Albany, Columbia, Rensselaer, Saratoga, and Schenectady counties; large parts of Greene and Washington counties; and the disputed southwest corner of Vermont.

The city of Albany was the first municipality within this large county, founded as the village (dorp in Dutch) of Beverwyck by the Director-General of New Amsterdam, Pieter Stuyvesant, who also established the first court in Albany. Albany was established as a city in 1686 by Governor Dongan through the Dongan Charter after the English took over the colony. Schenectady to the west was given a patent with some municipal rights in 1684 and became a borough in 1765.

The Manor of Rensselaerswyck was created as a district within the county in 1772, and later divided into two districts, one on each side of the Hudson River in 1779. The west district included all of what is now Albany County other than lands were in the city of Albany at the time. Though the Manor of Rensselaerswyck was the only district (along with the city of Albany) in what is today Albany County, it was not the only district in what was Albany County at the time. Pittstown in 1761, and Duanesburgh in 1764, were created as townships. But when districts were created in 1772, those townships were incorporated into new districts, Pittstown in Schaghticoke and Duanesburgh into the United Districts of Duanesburgh and Schoharie. Schenectady was also made from a borough to a district in 1772. Other districts established in 1772 were Hoosick, Coxsackie, Cambridge, Saratoga, Halfmoon, Kinderhook, Kings, Claverack, Great Imboght, and the Manor of Livingston.

In a census of 1697, there were 1,452 individuals living in Albany County; two years later it would be counted as 2,016 at the beginning of King William's War. By the end of the war in 1698, the population had dropped to 1,482, but rebounded quickly and was at 2,273 by 1703. By 1723, it had increased to 6,501 and in 1731 to 8,573, which was slightly less than the population of the city of New York in the same year. In 1737, the inhabitants of Albany County would outnumber those of New York County by 17 people. In 1774, Albany County, with 42,706 people, was the largest county in colonial New York. According to the first Federal Census in 1790, Albany County reached 75,921 inhabitants and was still the state's largest county.

Formation of towns
On March 7, 1788, the state of New York divided the entire state into towns eliminating districts as administrative units by passing New York Laws of 1788, Chapters 63 and 64.

Timeline of boundary changes
Albany County was one of the original twelve counties created by the Province of New York on November 1, 1683. At the time, it included all of New York state north of Dutchess and Ulster counties, all of what is now Bennington County in Vermont, and theoretically west to the Pacific Ocean.

On May 27, 1717, Albany County was adjusted to gain an indefinite amount of land from Dutchess County and other non-county lands.

On October 7, 1763, King George III, as part of his Proclamation of 1763, created the new province of Quebec, implicitly setting the northern limit of New York at the parallel of 45 degrees north latitude from the Atlantic-St. Lawrence watershed westward to the St. Lawrence River, implicitly setting the northern limit of Albany County, but it was never mapped.

On July 20, 1764, King George III established the boundary between New Hampshire and New York along the west bank of the Connecticut River, north of Massachusetts and south of the parallel of 45 degrees north latitude. Albany County implicitly gained present-day Vermont. Although disputes occasionally broke out later, this line became the boundary between New Hampshire and Vermont, and has remained unchanged to the present. When New York refused to recognize land titles through the New Hampshire Grants (towns created earlier by New Hampshire in present Vermont), dissatisfied colonists organized in opposition, which led to the creation of independent Vermont in 1777.

On July 3, 1766, Cumberland County was partitioned from Albany County to cover all territory to the northern and eastern limits of the colony, including Windsor County, most of Windham County, and parts of Bennington and Rutland counties in present-day Vermont.

On June 26, 1767, Albany County regained all of Cumberland County.

On March 19, 1768, Albany County was re-partitioned, and Cumberland County restored.

On March 16, 1770, Albany County was again partitioned. Gloucester County was created to include all of Orange, Caledonia and Essex counties, most of Washington County, and parts of Orleans, Lamoille, Addison and Chittenden counties in present-day Vermont.

On March 12, 1772, Albany County was partitioned again, this time into the counties of Albany, Tryon (now Montgomery), and Charlotte (now Washington). This established a definite area for Albany County of 5,470 sqmi.

On March 24, 1772, Albany County was partitioned again, with an additional 50 sqmi handed over to Cumberland County.

On March 9, 1774, Albany County was partitioned again, this time passing 1090 sqmi to Ulster County.

On April 1, 1775, Albany was again partitioned, this time giving up 60 sqmi to Charlotte County, who then exchanged this land with a like parcel in Cumberland County.

On January 15, 1777, Albany County was again partitioned, this time on account of the independence of Vermont from New York, reducing Albany County by an additional 300 sqmi.

On June 26, 1781, Bennington County, Vermont, attempted to annex a portion of Albany County that today includes portions of Washington and Rensselaer counties to form what they called "The West Union". The fledgling United States – under the Articles of Confederation – arbitrated this annexation, and condemned it, resulting in Vermont ceasing the annexation on 1782-02-23.

On April 4, 1786, Columbia County was created from 650 sqmi of Albany County land.

On March 7, 1788, New York, refusing to recognize the independence of Vermont, and the attendant elimination of Cumberland County, attempted to adjust the line that separated Cumberland from Albany County in present-day Vermont, but to no effect.

On February 7, 1791, Albany County was partitioned again, this time to form Rensselaer and Saratoga counties. Rensselaer received 660 sqmi, while Saratoga received 850 sqmi. Also the town of Cambridge was transferred to Washington County. A total of 1680 sqmi changed hands.

On June 1, 1795, Albany County was once again partitioned, this time losing 460 sqmi to Schoharie County.

On April 5, 1798, another partition took place, with 90 sqmi passing to Ulster County.

On March 25, 1800, once again Albany County was partitioned, with 360 sqmi being used to create Greene County.

On April 3, 1801, all New York counties were redefined, with Albany County gaining 10 sqmi.

On March 7, 1809, Schenectady County was created from 230 sqmi of Albany County land, reducing Albany County to its current size.

On March 3, 1888, Albany County ceded Havre Island to Saratoga County.

Geography

According to the U.S. Census Bureau, the county has a total area of 533 sqmi, of which 523 sqmi is land and 10 sqmi (2.0%) is water.

Albany County is in the east central part of New York, extending southward and westward from the point where the Mohawk River joins the Hudson River. Its eastern boundary is the Hudson; a portion of its northern boundary is the Mohawk.

The terrain of the county ranges from flat near the Hudson and Mohawk Rivers to high and hilly to the southwest, of the Helderberg Escarpment and the Helderberg Mountains. The highest point is one of several summits near Henry Hill at approximately 2,160 ft above sea level; The lowest point is 62 ft above sea level at the Hudson River's southernmost extent in the county.

Climate
The Capital District has a humid continental climate, with cold, snowy winters, and hot, wet summers. Albany receives around 36.2 in of rain per year, with 135 days of at least 0.01 in of precipitation. Snowfall is significant, totaling about 63 in annually, but with less accumulation than the lake-effect areas to the north and west, being far enough from Lake Ontario. Albany County is however, close enough to the coast to receive heavy snow from Nor'easters, and the region gets the bulk of its yearly snowfall from these types of storms. The county also occasionally receives Alberta clippers. Winters are often very cold with fluctuating conditions, temperatures often drop to below 0 °F at night. Summers in the Albany can contain stretches of excessive heat and humidity, with temperatures above 90 °F and dew points near 70. Severe thunderstorms are common but tornadoes are rare. Albany receives on average per year 69 sunny days, 111 partly cloudy days, and 185 cloudy days; and an average, over the course of a year, of less than four hours of sunshine per day, with just over an average of 2.5 hours per day over the course of the winter. The chance during daylight hours of sunshine is 53%, with the highest percentage of sunny daylight hours being in July with 64%, and the lowest month is November with 37%.

Adjacent counties
Albany County is bordered by six counties. Listed clockwise, they are:
 * Schenectady County – northwest
 * Saratoga County – north
 * Rensselaer County – east
 * Columbia County – southeast
 * Greene County – south
 * Schoharie County – west

Architecture
Albany County has myriad different architectural styles spanning centuries of development. Within the city of Albany alone there is Dutch Colonial (the Quackenbush House), French Renaissance (the New York State Capitol), Federal style (the original Albany Academy in Academy Park), Romanesque Revival (Albany City Hall), Art deco (the Alfred E. Smith Building), and Modern (Empire State Plaza). The cities of Albany, Cohoes, and Watervliet and the village of Green Island are more urban in architecture; while the towns of Colonie, Guilderland, New Scotland, and Bethlehem more suburban and the remaining Hilltowns (Berne, Knox, Westerlo, and Rensselaerville) very rural.

Parks
Albany County is home to the Emma Treadwell Thacher Nature Center, which opened in July 2001 and is near the shore of Thompson's Lake between the two state parks that are in Albany County- Thompson's Lake State Park and John Boyd Thacher State Park. There are also state-owned nature preserves with interactive educational programs such as the Five Rivers Environmental Education Center and the Albany Pine Bush. The cities, towns, and villages of Albany County have many municipal parks, playgrounds, and protected green areas. Washington Park in the city of Albany and The Crossing in the town of Colonie are two of the largest. There are many small hiking and biking trails and longer distance bike-hike trails such the Mohawk-Hudson Bike-Hike Trail which goes from the city of Albany north to Cohoes and then west along the Mohawk River to Schenectady County.

Festivals
One of the largest events in Albany County is the Tulip Fest held in the city of Albany every spring at Washington Park. The tradition stems from when Mayor Erastus Corning 2nd had a city ordinance passed declaring the tulip as Albany's official flower on July 1, 1948. The African-American tradition of Pinksterfest, whose origins are traced back even further to Dutch festivities, was later incorporated into the Tulip Fest. The Albany LatinFest has been held since 1996 and drew 10,000 to Washington Park in 2008. PolishFest is a three-day celebration of Polish culture in the Capital District, held in the town of Colonie for the past eight years.

Amusement

Albany County has two shopping malls classified as super-regional malls (malls with over 800,000 sq ft), Crossgates Mall in Guilderland and Colonie Center in Colonie with over one million square feet of rentable space in each. Huck Finn's Playland is a children's amusement park open during the summer, which started operations in the Summer of 2015—after purchasing the rides from the former Hoffman's Playland in Newtonville, which was in operation from 1951 to the Fall of 2014. During the winter there are over 18 mi of official trails for snowshoeing at the Albany Pine Bush Preserve, in the city of Albany and towns of Colonie and Guilderland.

Museums
Albany County has many historical sites and museums covering a wide range of topics and time periods. The Albany Institute of History and Art founded in 1791 is one of the oldest museums in the United States, and the New York State Museum is the oldest and largest state museum in the country. Many of the museums are historical sites themselves, such as Cherry Hill, the Ten Broeck Mansion, and the Schuyler Mansion in the city of Albany and the Pruyn House in Colonie. The Quackenbush House is the second oldest house in the city of Albany and is part of the Albany Heritage Area Visitors Center, which includes a planetarium. The Albany Pine Bush Discovery Center in the city of Albany includes hands-on activities to learn about the unique Pine Bush Barrens of the city of Albany and towns of Guilderland and Colonie. Covering the history of pharmacy is the Throop Drug Store Museum at the Albany College of Pharmacy. The USS Slater, DE-766 is a World War II Destroyer Escort, the last floating Destroyer Escort, owned by the Destroyer Escort Historical Museum is moored from Spring to Fall at the foot of Quay Street in the Hudson River. The ship is open for tours each week and contains an excellent and well-maintained collection of World War II US Naval artifacts.

There are several art museums in Albany County; including the Albany Center Gallery, in downtown Albany, which exhibits works by local artists within a 100 mi radius of that city; the University Art Museum, at the University at Albany, SUNY; and the Opalka Gallery, at the Sage College of Albany. The Empire State Plaza in Albany has one of the most important state collections of modern art in the U.S.

Performing arts
Albany County itself owns the largest venue for performing arts in the county, the Times Union Center, which was originally built as the Knickerbocker Arena; it opened on January 30, 1990, with a performance by Frank Sinatra. In 1996, The Grateful Dead released a concert album from their March 1990 performances titled Dozin' at the Knick.

Sports
Many athletes and coaches in major sports have begun their careers in Albany County. Phil Jackson, former NBA head coach of the Chicago Bulls and Los Angeles Lakers won his first championship ring as a coach when he guided the Albany Patroons to the 1984 CBA championship. Three years later, the Patroons completed a 50–6 regular season, including winning all 28 of their home games; at that time, Sacramento Kings head coach George Karl was the Patroons' head coach. Future NBA stars Mario Elie and Vincent Askew were part of that season's squad. Mike Tyson received his early training in the Capital District and his first professional fight was in Albany in 1985 and Tyson's first televised fight was in Troy in 1986. He fought professionally four times in Albany and twice each in Troy and Glens Falls between 1985 and 1986.

Since 1988, the Siena College men's basketball team (the Siena Saints) have appeared in six NCAA Tournaments (1989, 1999, 2002, 2008, 2009, and 2010).

Religious life
Albany County was originally settled primarily by Protestants from northern Europe: the Netherlands, British Isles, and Germany. In the 19th century it was a destination for many Catholic immigrants, first from Ireland – fleeing the Great Famine, and later from southern Germany, central and southern Europe. Late 19th and early 20th century immigrants included Jews from eastern Europe. In addition to other Jewish congregations, the county has one of the few Karaite Jewish communities outside Israel. This community is active and has its own synagogue. The Albany Metro Area has consistently been found to be among the highest ranking postchristian cities in the US.

Demographics
As of the 2020 US Census, there were 314,848 people in 126,540 households residing in the county. The population density was 563 PD/sqmi. There were 134,072 housing units at an average density of 248 /mi2.

Tech Valley
Since the 2000s, the economy of Albany County and the surrounding Capital District has been redirected toward high technology. Tech Valley is a marketing name for the eastern part of New York State, encompassing Albany County, the Capital District, and the Hudson Valley. Originated in 1998 to promote the greater Albany area as a high-tech competitor to regions such as Silicon Valley and Boston, it has since grown to represent the counties in the Capital District and extending to IBM's Westchester County plants in the south and the Canada–US border to the north. The area's high technology ecosystem is supported by technologically focused academic institutions including Rensselaer Polytechnic Institute and the State University of New York Polytechnic Institute. Tech Valley encompasses 19 counties straddling both sides of the Adirondack Northway and the New York Thruway, and with heavy state taxpayer subsidy, has experienced significant growth in the computer hardware side of the high-technology industry, with great strides in the nanotechnology sector, digital electronics design, and water- and electricity-dependent integrated microchip circuit manufacturing.

Government and politics
For most of its history, Albany County has predominantly backed Democratic Party presidential candidates. In only three elections since 1924 has a Republican Party candidate carried the county in a presidential election, the most recent being Richard Nixon in 1972. The Democratic Party dominance has become more pronounced in recent years, with George H. W. Bush in 1988 the most recent Republican candidate to win even forty percent of the county's vote.

 * }

Albany County was governed by a board of supervisors until 1968. The board consisted of the town supervisors of each town in the county, as well as county supervisors elected from the wards of each city in the county. In the later years of its existence, the board used a system of weighted voting to comply with recently enacted federal and state proportional representation requirements. On January 1, 1976, Albany County government was changed by a new charter establishing a county executive elected at-large, in addition to the 39-seat county legislature. Each of the 39 legislators are elected from single-member districts. As of 2023, the county legislature has 29 Democrats, 10 Republicans.

The County Executive is Daniel P. McCoy (D). Other officials elected countywide include District Attorney David Soares, Clerk Bruce A. Hidley, Comptroller Susan A. Rizzo, and Sheriff Craig D. Apple. Other elected officials with districts in the county include:
 * State Assembly
 * Christopher Tague, Republican, 102nd District
 * John McDonald, Democratic, 108th District
 * Pat Fahy, Democratic, 109th District
 * Phillip Steck, Democratic, 110th District
 * Angelo Santabarbara, Democratic, 111th District
 * State Senate
 * Neil Breslin, Democratic, 44th District
 * Michelle Hinchey, Democratic, 46th District
 * United States House of Representatives
 * Paul Tonko, Democratic, 20th District

Law enforcement
The Albany County Sheriff's Department is one of the oldest law enforcement agencies in the United States, having been established in the 1660s. Sheriff Craig Apple was first elected in 2011.

The sheriff is also responsible for the county jail, which was built in 1931, and renamed from the Albany County Correctional Facility to the Albany County Corrections and Rehabilitative Services Center in 2019. This jail has a contract with New York City to accept prisoners from their facilities. The New York Times has reported that juveniles sent to Albany were beaten and placed in isolation, which is forbidden in New York City.

The department investigated a criminal complaint against Governor Andrew Cuomo during the Andrew Cuomo sexual harassment allegations, and filed a misdemeanor criminal complaint on its own authority to bring charges.

Transportation
Albany County has long been at the forefront of transportation technology from the days of turnpikes and plank roads to the Erie Canal, from the first passenger railroad in the state to the oldest municipal airport in the United States. Today, Interstates, Amtrak, and the Albany International Airport continue to make the Albany County a major crossroads of the Northeastern United States.

The Capital District Transportation Committee (CDTC) is the Metropolitan Planning Organization (MPO) for the Albany-Schenectady-Troy Metropolitan Statistical Area (MSA). Every metropolitan area in the United States with a population of over 50,000 must have a MPO in order to get any federal transportation funding. The US Department of Transportation (USDOT) uses an MPO to make decisions on what projects are most important to a metro area for immediate versus long term funding. The USDOT will not approve federal funds for transportation projects unless they are on an MPO's list.

Interstate and other major highways
Albany County is situated at a major crossroads of the Northeastern United States, first formed by the Mohawk and Hudson rivers. Even before the Interstate Highway System and the U.S. Highway system, Albany County was the hub of many turnpikes and plank roads that connected the region, as well as the Erie Canal reaching the Great Lakes.

Today, Interstate 87 and Interstate 90 meet in Albany County. The Thomas E. Dewey New York State Thruway is a toll-road that from Exit 24 in the city of Albany is I-87 and travels south to connect the county with downstate New York. West from Exit 24, the Thruway is I-90 and connects the county with Schenectady, Utica, Syracuse, Rochester, and Buffalo.

North of Exit 24, I-87 is the Adirondack Northway and connects the city and county of Albany with their suburbs in Saratoga County and provides long-distance travel to Montreal. East of Exit 24, I-90 travels along the northern boundary of the city of Albany and exits the county on the Patroon Island Bridge into Rensselaer County to access Albany's eastern suburbs. Interstate 787 connects the Thruway (I-87) to Downtown Albany, Menands, Watervliet, and Cohoes. U.S. Route 9 enters the county on the Dunn Memorial Bridge and travels through the city of Albany north, connecting it with the suburbs in the Colonie and Saratoga County. U.S. Route 20 also enters the county on the Dunn Memorial Bridge and travels west through Albany (city) and the Town of Guilderland. New York State Route 5 and New York State Route 7 are two important highways that bisect the county and are developed as important shopping strips.

Mass transit
Albany County is served by the Capital District Transportation Authority, a five-county bus service that also serves Rensselaer, Schenectady, Montgomery and Saratoga counties. Greyhound Lines, Trailways, and Peter Pan Bus Lines buses all serve a downtown terminal. Chinatown bus lines leaves from Central Avenue and provide service to Chinatown, Manhattan.

Airports
Albany International Airport is the only commercial airport in the county. Destinations for flights out of Albany include Atlanta; Las Vegas; Chicago; Charlotte, North Carolina; and Orlando, Florida, among many others.

Rail
Since 1968 when Union Station in the city of Albany was abandoned for a new station across the Hudson in the city of Rensselaer, Albany County has been without a train station. Amtrak has several routes serving the Albany-Rensselaer Station. The Adirondack (north to Montreal, Quebec and south to the city of New York), Empire Service (west to Buffalo and Niagara Falls, south to New York), Ethan Allen Express (northeast to Rutland, Vermont and south to New York), Maple Leaf (west to Toronto and south to New York), and the Lake Shore Limited (at Albany-Rensselaer separate routes from Boston and New York merge to one train west to Chicago, on way east one train splits to two, one east to Boston and another south to New York).

Lemures

The lemures were shades or spirits of the restless or malignant dead in Roman religion, and are probably cognate with an extended sense of larvae  (from Latin larva, 'mask') as disturbing or frightening. Lemures is the more common literary term but even this is rare: it is used by the Augustan poets Horace and Ovid, the latter in his Fasti, the six-book calendar poem on Roman holidays and religious customs.

The word lemures can be traced to the PIE stem *, which also appears in the name of the Greek monster Lamia.

Description
Lemures may represent the wandering and vengeful spirits of those not afforded proper burial, funeral rites or affectionate cult by the living: they are thus not attested by tomb or votive inscriptions. Ovid interprets them as vagrant, unsatiated and potentially vengeful di manes or di parentes, ancestral gods or spirits of the underworld. To him, the rites of their cult suggest an incomprehensibly archaic, quasi-magical and probably very ancient rural tradition.

Lemures were formless and liminal, associated with darkness and its dread. In Republican and Imperial Rome, May 9, 11, and 13 were dedicated to their placation in the household practices of Lemuralia or Lemuria. The head of household (paterfamilias) would rise at midnight and cast black beans behind him with averted gaze; the Lemures were presumed to feast on them. Black was the appropriate colour for offerings to chthonic deities. William Warde Fowler interprets the gift of beans as an offer of life, and points out that they were a ritual pollution for priests of Jupiter. The lemures themselves were both fearsome and fearful: any malevolent shades dissatisfied with the offering of the paterfamilias could be startled into flight by the loud banging of bronze pots.

In scientific Latin
The lemures inspired Linnaeus's Modern Latin backformation lemur (denoting a type of primates). According to Linnaeus' own explanation, the name was selected because of the nocturnal activity and slow movements of the slender loris. Being familiar with the works of Virgil and Ovid and seeing an analogy that fit with his naming scheme, Linnaeus adapted the term lemur for these nocturnal primates. However, it has been commonly and falsely assumed that Linnaeus was referring to the ghost-like appearance, reflective eyes, and ghostly cries of lemurs. In Goethe's Faust, a chorus of Lemurs who serve Mephistopheles dig Faustus' grave.

In the English Daemonologie
In the book by King James I of England, Daemonologie, In Forme of a Dialogie, Divided into three Bookes, it is written: "Nowe I returne to my purpose: As to the first kinde of these spirites, that were called by the auncients by diuers names, according as their actions were. For if they were spirites that haunted some houses, by appearing in diuers and horrible formes, and making greate dinne: they were called Lemures or Spectra. If they appeared in likenesse of anie defunct to some friends of his, they wer called vmbræ mortuorum: And so innumerable stiles they got, according to their actiones, as I haue said alreadie. As we see by experience, how manie stiles they haue given them in our language in the like maner: Of the appearing of these spirites, wee are certified by the Scriptures, [marginal note - Esay. 13. Iere. 50] where the Prophet ESAY 13. and 34. cap. threatening the destruction of Babell and Edom: declares, that it shal not onlie be wracked, but shall become so greate a solitude, as it shall be the habitackle of Howlettes, and of ZIIM and IIM, which are the proper Hebrewe names for these Spirites. The cause whie they haunte solitarie places, it is by reason, that they may affraie and brangle the more the faith of suche as them alone hauntes such places. For our nature is such, as in companies wee are not so soone mooued to anie such kinde of feare, as being solitare, which the Deuill knowing well inough, hee will not therefore assaile vs but when we are weake: And besides that, GOD will not permit him so to dishonour the societies and companies of Christians, as in publicke times and places to walke visiblie amongst them. On the other parte, when he troubles certaine houses that are dwelt in, it is a sure token either of grosse ignorance, or of some grosse and slanderous sinnes amongst the inhabitantes thereof: which God by that extraordinarie rod punishes."

Smyrna

Smyrna (Σμύρνη, or Σμύρνα, ) was an Ancient Greek city located at a strategic point on the Aegean coast of Anatolia. Due to its advantageous port conditions, its ease of defence, and its good inland connections, Smyrna rose to prominence. Since about 1930, the city's name has been İzmir.

Two sites of the ancient city are today within İzmir's boundaries. The first, probably founded by indigenous peoples, rose to prominence during the Archaic Period as one of the principal ancient Greek settlements in western Anatolia. The second, whose foundation is associated with Alexander the Great, reached metropolitan proportions during the period of the Roman Empire. Most of the ancient city's present-day remains date to the Roman era, the majority from after a 2nd-century AD earthquake. In practical terms, a distinction is often made between these. Old Smyrna was the initial settlement founded around the 11th century BC, first as an Aeolian settlement, and later taken over and developed during the Archaic Period by the Ionians. Smyrna proper was the new city to which residents moved as of the 4th century BC and whose foundation was inspired by Alexander the Great.

Localization
Old Smyrna was on a small peninsula connected to the mainland by a narrow isthmus at the northeastern corner of the inner Gulf of İzmir, at the edge of a fertile plain and at the foot of Mount Yamanlar. This Anatolian settlement commanded the gulf. Today, the archaeological site, named Bayraklı Höyüğü, is approximately 700 m inland, in the Tepekule neighbourhood of Bayraklı. New Smyrna developed simultaneously on the slopes of the Mount Pagos (Kadifekale today) and alongside the coastal strait, immediately below where a small bay existed until the 18th century.

The core of the late Hellenistic and early Roman Smyrna is preserved in the large area of İzmir Agora Open Air Museum at this site. Research is being pursued at the sites of both the old and the new cities. This has been conducted since 1997 for Old Smyrna and since 2002 for the Classical Period city, in collaboration between the İzmir Archaeology Museum and the Metropolitan Municipality of İzmir.

Smyrna was at the mouth of the small river Hermus and at the head of a deep arm of the sea (Smyrnaeus Sinus) that reached far inland. This enabled Greek trading ships to sail into the heart of Lydia, making the city part of an essential trade route between Anatolia and the Aegean. During the 7th century BC, Smyrna rose to power and splendor. One of the great trade routes that cross Anatolia descends the Hermus valley past Sardis, and then, diverging from the valley, passes south of Mount Sipylus and crosses a low pass into the little valley where Smyrna lies between the mountains and the sea. Miletus and later Ephesus were at the sea end of the other great trade route across Anatolia; for a time they successfully competed with Smyrna, but after both cities' harbors silted up, Smyrna was without a rival.

The Meles River, which flowed by Smyrna, is famous in literature and was worshipped in the valley. A common and consistent tradition connects Homer with the valley of Smyrna and the banks of the Meles; his figure was one of the stock types on coins of Smyrna, one class of which numismatists call "Homerian." The epithet Melesigenes was applied to him; the cave where he was wont to compose his poems was shown near the source of the river; his temple, the Homereum, stood on its banks. The steady, equable flow of the Meles, alike in summer and winter, and its short course, beginning and ending near the city, are celebrated by Aristides and Himerius. The stream rises from abundant springs east of the city and flows into the southeast extremity of the gulf.

Hellenistic period
Alexander the Great conceived the idea of restoring the Greek city in a scheme that was, according to Strabo, actually carried out under Antigonus (316–301 BC) and Lysimachus (301 BC—281 BC), who enlarged and fortified the city. The ruined acropolis of the ancient city, the "crown of Smyrna", had been on a steep peak about 1250 ft high, which overhangs the northeast extremity of the gulf. Modern İzmir was constructed atop the later Hellenistic city, partly on the slopes of a rounded hill the Greeks called Pagos near the southeast end of the gulf, and partly on the low ground between the hill and the sea. The beauty of the Hellenistic city, clustering on the low ground and rising tier over tier on the hillside, was frequently praised by the ancients and is celebrated on its coins.

Smyrna is shut in on the west by a hill now called Deirmen Tepe, with the ruins of a temple on the summit. The walls of Lysimachus crossed the summit of this hill, and the acropolis occupied the top of Pagus. Between the two the road from Ephesus entered the city by the Ephesian gate, near which was a gymnasium. Closer to the acropolis the outline of the stadium is still visible, and the theatre was on Pagus's north slopes. Smyrna possessed two harbours. The outer harbour was simply the open roadstead of the gulf, and the inner was a small basin with a narrow entrance partially filled up by Tamerlane in 1402.

The streets were broad, well paved and laid out at right angles; many were named after temples: the main street, called the Golden, ran across the city from west to east, beginning probably from the temple of Zeus Akraios on the west slope of Pagus, and running round the lower slopes of Pagus (like a necklace on the statue, to use the favorite terms of Aristides the orator) towards Tepecik outside the city on the east, where probably stood the temple of Cybele, worshipped under the name of Meter Sipylene, the city's patroness. The name is from nearby Mount Sipylus, which bounds the valley of the city's backlands. The plain towards the sea was too low to be properly drained, and in rainy weather, the lower town's streets were deep with mud and water.

At the end of the Hellenistic period, in 197 BC, the city suddenly cut its ties with King Eumenes of Pergamum and appealed to Rome for help. Because Rome and Smyrna had no ties until then, Smyrna created a cult of Rome to establish a bond, and the cult eventually became widespread throughout the Roman Empire. As of 195 BC, the city of Rome started to be deified, in the cult to the goddess Roma. In this sense, the Smyrneans can be considered as the creators of the goddess Roma.

In 133 BC, when the last Attalid king, Attalus III, died without an heir, his will conferred his entire kingdom, including Smyrna, to the Romans. They organized it into the Roman province of Asia, making Pergamum the capital. As a major seaport, Smyrna became a leading city in the newly constituted province.

Roman and Byzantine period
As one of the principal cities of Roman Asia, Smyrna vied with Ephesus and Pergamum for the title "First City of Asia."

A Christian church and a bishopric existed there from earliest times, probably originating in the considerable Jewish colony. It was one of the seven churches addressed in the Book of Revelation. Saint Ignatius of Antioch visited Smyrna and later wrote letters to its bishop, Polycarp. A mob of Jews and pagans abetted the martyrdom of Polycarp in AD 153. Saint Irenaeus, who heard Polycarp as a boy, was probably a native of Smyrna. Another famous resident of the same period was Aelius Aristides.

After a destructive earthquake in 178 AD, Smyrna was rebuilt in the Roman period (2nd century AD) under the emperor Marcus Aurelius. Aelius Aristides wrote a letter to Marcus Aurelius and his son Commodus, inviting them to become the new founders of the city. The bust of the emperor's wife Faustina on the second arch of the western stoa confirms this fact.

Polycrates reports a succession of bishops including Polycarp of Smyrna, as well as others in nearby cities such as Melito of Sardis. Of that time, the German historian W. Bauer wrote:

"Asian Jewish Christianity received in turn the knowledge that henceforth the 'church' would be open without hesitation to the Jewish influence mediated by Christians, coming not only from the apocalyptic traditions, but also from the synagogue with its practices concerning worship, which led to the appropriation of the Jewish passover observance. Even the observance of the sabbath by Christians appears to have found some favor in Asia...we find that in post-apostolic times, in the period of the formation of ecclesiastical structure, the Jewish Christians in these regions come into prominence."

In the late second century, Irenaeus also noted:

"Polycarp also was not only instructed by apostles, and conversed with many who had seen Christ, but was also, by apostles in Asia, appointed bishop of the Church in Smyrna…always taught the things which he had learned from the apostles, and which the Church has handed down, and which alone are true. To these things all the Asiatic Churches testify, as do also those men who have succeeded Polycarp."

Tertullian wrote c. 208 AD:

"Anyhow the heresies are at best novelties, and have no continuity with the teaching of Christ. Perhaps some heretics may claim Apostolic antiquity: we reply: Let them publish the origins of their churches and unroll the catalogue of their bishops till now from the Apostles or from some bishop appointed by the Apostles, as the Smyrnaeans count from Polycarp and John, and the Romans from Clement and Peter; let heretics invent something to match this."

Hence, the church in Smyrna was apparently one of the churches that Tertullian felt had real apostolic succession.

During the mid-3rd century, most became affiliated with the Greco-Roman churches.

When Constantinople became the seat of government, the trade between Anatolia and the West diminished in importance, and Smyrna declined.

The Seljuq commander Tzachas seized Smyrna in 1084 and used it as a base for naval raids, but the city was recovered by the general John Doukas.

The city was several times ravaged by the Turks, and had become quite ruinous when the Nicaean emperor John III Doukas Vatatzes rebuilt it about 1222.

Ottoman period

Ibn Batuta found Smyrna still in great part a ruin when the homonymous chieftain of the Beylik of Aydın had conquered it about 1330 and made his son, Umur, governor. It became the port of the emirate.

During the Smyrniote Crusade in 1344, on October 28, the combined forces of the Knights Hospitaliers of Rhodes, the Republic of Venice, the Papal States, and the Kingdom of Cyprus captured both the harbor and city from the Turks, which they held for nearly 60 years; the citadel fell in 1348, with the death of the governor Umur Baha ad-Din Ghazi.

In 1402, Tamerlane stormed the town and massacred almost all the inhabitants. His conquest was only temporary, but Smyrna was recovered by the Turks under the Aydın dynasty, after which it became Ottoman, when the Ottomans took over the lands of Aydın after 1425.

Greek influence was so strong in the area that the Turks called it "Smyrna of the infidels" (Gavur İzmir). Turkish sources track the term's emergence to the 14th century, when two separate parts of the city were controlled by two different powers, the upper İzmir being Muslim and the lower part of the city Christian.

The Armenians, alongside the Greeks, played a significant role in the city's development, most notably during the age of exploration, where Armenians became a crucial player in the trade sector. The Armenians had trade routes stretching from the far east to Europe. One most notable good the Armenians traded was Iranian silk, which the Shah Abbas of Iran gave them a monopoly over in the 17th century.

The Armenians traded Iranian silk with European and Greek merchants in Smyrna; this trade made the Armenians very rich. Besides trade, the Armenians were involved in manufacturing, banking, and other highly productive professions.

During the late 19th and early 20th centuries, Smyrna was an important financial and cultural center of the Greek world. Of its 391 factories, 322 belonged to local Greeks, while 3 of its 9 banks were backed by Greek capital. Education was also dominated by the local Greek communities, with 67 male and 4 female schools. The Ottomans continued to control the area, with the exception of the 1919–1922 period, when the city was assigned to Greece by the Treaty of Sèvres.

The region's most important Greek educational institution was the Evangelical School, which operated from 1733 to 1922.

Post-World War I

After the end of the First World War, Greece occupied Smyrna from 15 May 1919 and put in place a military administration. The Greek premier Venizelos had plans to annex Smyrna and he seemed to be realizing his objective in the Treaty of Sèvres, signed 10 August 1920. (However, this treaty was not ratified by the parties; the Treaty of Peace of Lausanne replaced it.)

The occupation of Smyrna came to an end when the Turkish army of Kemal Atatürk entered the city on September 9, 1922, at the end of the Greco-Turkish War (1919–1922). In the immediate aftermath, a fire broke out in the Greek and Armenian quarters of the city on September 13, 1922, known as the Great Fire of Smyrna. The death toll is estimated to range from 10,000 to 100,000.

Agora
The remains of the ancient agora of Smyrna constitute today the space of İzmir Agora Museum in İzmir's Namazgah quarter, although its area is commonly referred to as "Agora" by the city's inhabitants.

Situated on the northern slopes of the Pagos hills, it was the commercial, judicial and political nucleus of the ancient city, its center for artistic activities and for teaching.

İzmir Agora Open Air Museum consists of five parts, including the agora area, the base of the northern basilica gate, the stoa and the ancient shopping centre.

The agora of Smyrna was built during the Hellenistic era.

Excavations
Although Smyrna was explored by Charles Texier in the 19th century and the German consul in İzmir had purchased the land around the ancient theater in 1917 to start excavations, the first scientific digs can be said to have started in 1927. Most of the discoveries were made by archaeological exploration carried as an extension during the period between 1931 and 1942 by the German archaeologist Rudolf Naumann and Selâhattin Kantar, the director of İzmir and Ephesus museums. They uncovered a three-floor, rectangular compound with stairs in the front, built on columns and arches around a large courtyard in the middle of the building.

New excavations in the agora began in 1996. They have continued since 2002 under the sponsorship of the Metropolitan Municipality of İzmir. A primary school adjacent to the agora that had burned in 1980 was not reconstructed. Instead, its space was incorporated into the historical site. The area of the agora was increased to 16590 m2. This permitted the evacuation of a previously unexplored zone. The archaeologists and the local authorities, means permitting, are also keenly eyeing a neighbouring multi-storey car park, which is known to cover an important part of the ancient settlement. During the present renovations the old restorations in concrete are gradually being replaced by marble.

The new excavation has uncovered the agora's northern gate. It has been concluded that embossed figures of the goddess Hestia found in these digs were a continuation of the Zeus altar uncovered during the first digs. Statues of the gods Hermes, Dionysos, Eros and Heracles have also been found, as well as many statues, heads, embossments, figurines and monuments of people and animals, made of marble, stone, bone, glass, metal and terracotta. Inscriptions found here list the people who provided aid to Smyrna after the earthquake of 178 AD.

Economy
In the early 20th-century, Smyrna had a number of mills spinning thread. As of 1920, there were two factories in Smyrna dyeing yarn, which were owned by British companies. These companies employed over 60,000 people. During this time, there was also a French owned cotton spinning mill. The city also produced soap made of refuse olive oil. An ironworks, also owned by the British, produced tools and equipment. Those tools were used to extract tannin from valonia oak. As of 1920, the ironwork was exporting 5,000 tons of product a year. The city also produced wooden boxes, which were used for fig and raisin storage. The wood for the boxes was imported from Austria and Romania.

Toponyms
Several American cities have been named after Smyrna, including Smyrna, Georgia; Smyrna, Tennessee; Smyrna, North Carolina; Smyrna, South Carolina; Smyrna, Delaware; Smyrna, Michigan; Smyrna, Maine and New Smyrna Beach, Florida.

Sucrose

Sucrose, a disaccharide, is a sugar composed of glucose and fructose subunits. It is produced naturally in plants and is the main constituent of white sugar. It has the molecular formula.

For human consumption, sucrose is extracted and refined from either sugarcane or sugar beet. Sugar mills – typically located in tropical regions near where sugarcane is grown – crush the cane and produce raw sugar which is shipped to other factories for refining into pure sucrose. Sugar beet factories are located in temperate climates where the beet is grown, and process the beets directly into refined sugar. The sugar-refining process involves washing the raw sugar crystals before dissolving them into a sugar syrup which is filtered and then passed over carbon to remove any residual colour. The sugar syrup is then concentrated by boiling under a vacuum and crystallized as the final purification process to produce crystals of pure sucrose that are clear, odorless, and sweet.

Sugar is often an added ingredient in food production and recipes. About 185 million tonnes of sugar were produced worldwide in 2017.

Sucrose is particularly dangerous as a risk factor for tooth decay because Streptococcus mutans bacteria convert it into a sticky, extracellular, dextran-based polysaccharide that allows them to cohere, forming plaque. Sucrose is the only sugar that bacteria can use to form this sticky polysaccharide.

Etymology
The word sucrose was coined in 1857, by the English chemist William Miller from the French sucre ("sugar") and the generic chemical suffix for sugars -ose. The abbreviated term Suc is often used for sucrose in scientific literature.

The name saccharose was coined in 1860 by the French chemist Marcellin Berthelot. Saccharose is an obsolete name for sugars in general, especially sucrose.

Structural O-α- D -glucopyranosyl-(1→2)-β- D -fructofuranoside
In sucrose, the monomers glucose and fructose are linked via an ether bond between C1 on the glucosyl subunit and C2 on the fructosyl unit. The bond is called a glycosidic linkage. Glucose exists predominantly as a mixture of α and β "pyranose" anomers, but sucrose has only the α form. Fructose exists as a mixture of five tautomers but sucrose has only the β- D -fructofuranose form. Unlike most disaccharides, the glycosidic bond in sucrose is formed between the reducing ends of both glucose and fructose, and not between the reducing end of one and the non-reducing end of the other. This linkage inhibits further bonding to other saccharide units, and prevents sucrose from spontaneously reacting with cellular and circulatory macromolecules in the manner that glucose and other reducing sugars do. Since sucrose contains no anomeric hydroxyl groups, it is classified as a non-reducing sugar.

Sucrose crystallizes in the monoclinic space group P21 with room-temperature lattice parameters a = 1.08631 nm, b = 0.87044 nm, c = 0.77624 nm, β = 102.938°.

The purity of sucrose is measured by polarimetry, through the rotation of plane-polarized light by a sugar solution. The specific rotation at 20 °C using yellow "sodium-D" light (589 nm) is +66.47°. Commercial samples of sugar are assayed using this parameter. Sucrose does not deteriorate at ambient conditions.

Thermal and oxidative degradation
Sucrose does not melt at high temperatures. Instead, it decomposes at 186 °C to form caramel. Like other carbohydrates, it combusts to carbon dioxide and water by the simplified equation:

C12H22O11 + 12 O2 → 12 CO2 + 11 H2O

Mixing sucrose with the oxidizer potassium nitrate produces the fuel known as rocket candy that is used to propel amateur rocket motors.

C12H22O11 + 6 KNO3 -> 9 CO + 3 N2 + 11 H2O + 3 K2CO3

This reaction is somewhat simplified though. Some of the carbon does get fully oxidized to carbon dioxide, and other reactions, such as the water-gas shift reaction also take place. A more accurate theoretical equation is:

C12H22O11 + 6.288 KNO3 -> 3.796 CO2 + 5.205 CO + 7.794 H2O + 3.065 H2 + 3.143 N2 + 2.988 K2CO3 + 0.274 KOH

Sucrose burns with chloric acid, formed by the reaction of hydrochloric acid and potassium chlorate:

8 HClO3 + C12H22O11 -> 11 H2O + 12 CO2 + 8 HCl

Sucrose can be dehydrated with sulfuric acid to form a black, carbon-rich solid, as indicated in the following idealized equation:

H2SO4 (catalyst) + C12H22O11 -> 12 C + 11 H2O + heat (and some H2O + SO3 as a result of the heat).

The formula for sucrose's decomposition can be represented as a two-step reaction: the first simplified reaction is dehydration of sucrose to pure carbon and water, and then carbon oxidises to CO2 with O2 from air.

C12H22O11 + heat -> 12 C + 11 H2O

12 C + 12 O2 -> 12 CO2

Hydrolysis
Hydrolysis breaks the glycosidic bond converting sucrose into glucose and fructose. Hydrolysis is, however, so slow that solutions of sucrose can sit for years with negligible change. If the enzyme sucrase is added, however, the reaction will proceed rapidly. Hydrolysis can also be accelerated with acids, such as cream of tartar or lemon juice, both weak acids. Likewise, gastric acidity converts sucrose to glucose and fructose during digestion, the bond between them being an acetal bond which can be broken by an acid.

Given (higher) heats of combustion of 1349.6 kcal/mol for sucrose, 673.0 for glucose, and 675.6 for fructose, hydrolysis releases about 1.0 kcal per mole of sucrose, or about 3 small calories per gram of product.

Synthesis and biosynthesis of sucrose
The biosynthesis of sucrose proceeds via the precursors UDP-glucose and fructose 6-phosphate, catalyzed by the enzyme sucrose-6-phosphate synthase. The energy for the reaction is gained by the cleavage of uridine diphosphate (UDP). Sucrose is formed by plants, algae and cyanobacteria but not by other organisms. Sucrose is the end product of photosynthesis and is found naturally in many food plants along with the monosaccharide fructose. In many fruits, such as pineapple and apricot, sucrose is the main sugar. In others, such as grapes and pears, fructose is the main sugar.

Chemical synthesis
After numerous unsuccessful attempts by others, Raymond Lemieux and George Huber succeeded in synthesizing sucrose from acetylated glucose and fructose in 1953.

History of sucrose refinement

The production of table sugar has a long history. Some scholars claim Indians discovered how to crystallize sugar during the Gupta dynasty, around CE 350.

Other scholars point to the ancient manuscripts of China, dated to the 8th century BCE, where one of the earliest historical mentions of sugar cane is included along with the fact that their knowledge of sugar cane was derived from India. By about 500 BCE, residents of modern-day India began making sugar syrup, cooling it in large flat bowls to produce raw sugar crystals that were easier to store and transport. In the local Indian language, these crystals were called (खण्ड), which is the source of the word candy.

The army of Alexander the Great was halted on the banks of river Indus by the refusal of his troops to go further east. They saw people in the Indian subcontinent growing sugarcane and making "granulated, salt-like sweet powder", locally called (साखर), (شکر), pronounced as  (ζακχαρον) in Greek (Modern Greek,, ζάχαρη). On their return journey, the Greek soldiers carried back some of the "honey-bearing reeds". Sugarcane remained a limited crop for over a millennium. Sugar was a rare commodity and traders of sugar became wealthy. Venice, at the height of its financial power, was the chief sugar-distributing center of Europe. Moors started producing it in Sicily and Spain. Only after the Crusades did it begin to rival honey as a sweetener in Europe. The Spanish began cultivating sugarcane in the West Indies in 1506 (Cuba in 1523). The Portuguese first cultivated sugarcane in Brazil in 1532.

Sugar remained a luxury in much of the world until the 18th century. Only the wealthy could afford it. In the 18th century, the demand for table sugar boomed in Europe and by the 19th century it had become regarded as a human necessity. The use of sugar grew from use in tea, to cakes, confectionery and chocolates. Suppliers marketed sugar in novel forms, such as solid cones, which required consumers to use a sugar nip, a pliers-like tool, in order to break off pieces.

The demand for cheaper table sugar drove, in part, colonization of tropical islands and nations where labor-intensive sugarcane plantations and table sugar manufacturing could thrive. Growing sugar cane crop in hot humid climates, and producing table sugar in high temperature sugar mills was harsh, inhumane work. The demand for cheap labor for this work, in part, first drove slave trade from Africa (in particular West Africa), followed by indentured labor trade from South Asia (in particular India). Millions of slaves, followed by millions of indentured laborers were brought into the Caribbean, Indian Ocean, Pacific Islands, East Africa, Natal, north and eastern parts of South America, and southeast Asia. The modern ethnic mix of many nations, settled in the last two centuries, has been influenced by table sugar.

Beginning in the late 18th century, the production of sugar became increasingly mechanized. The steam engine first powered a sugar mill in Jamaica in 1768, and, soon after, steam replaced direct firing as the source of process heat. During the same century, Europeans began experimenting with sugar production from other crops. Andreas Marggraf identified sucrose in beet root and his student Franz Achard built a sugar beet processing factory in Silesia (Prussia). The beet-sugar industry took off during the Napoleonic Wars, when France and the continent were cut off from Caribbean sugar. In 2009, about 20 percent of the world's sugar was produced from beets.

Today, a large beet refinery producing around 1,500 tonnes of sugar a day needs a permanent workforce of about 150 for 24-hour production.

Trends

Table sugar (sucrose) comes from plant sources. Two important sugar crops predominate: sugarcane (Saccharum spp.) and sugar beets (Beta vulgaris), in which sugar can account for 12% to 20% of the plant's dry weight. Minor commercial sugar crops include the date palm (Phoenix dactylifera), sorghum (Sorghum vulgare), and the sugar maple (Acer saccharum). Sucrose is obtained by extraction of these crops with hot water; concentration of the extract gives syrups, from which solid sucrose can be crystallized. In 2017, worldwide production of table sugar amounted to 185 million tonnes.

Most cane sugar comes from countries with warm climates, because sugarcane does not tolerate frost. Sugar beets, on the other hand, grow only in cooler temperate regions and do not tolerate extreme heat. About 80 percent of sucrose is derived from sugarcane, the rest almost all from sugar beets.

In mid-2018, India and Brazil had about the same production of sugar – 34 million tonnes – followed by the European Union, Thailand, and China as the major producers. India, the European Union, and China were the leading domestic consumers of sugar in 2018.

Beet sugar comes from regions with cooler climates: northwest and eastern Europe, northern Japan, plus some areas in the United States (including California). In the northern hemisphere, the beet-growing season ends with the start of harvesting around September. Harvesting and processing continues until March in some cases. The availability of processing plant capacity and the weather both influence the duration of harvesting and processing – the industry can store harvested beets until processed, but a frost-damaged beet becomes effectively unprocessable.

The United States sets high sugar prices to support its producers, with the effect that many former purchasers of sugar have switched to corn syrup (beverage manufacturers) or moved out of the country (candy manufacturers).

The low prices of glucose syrups produced from wheat and corn (maize) threaten the traditional sugar market. Used in combination with artificial sweeteners, they can allow drink manufacturers to produce very low-cost goods.

High-fructose corn syrup
High-fructose corn syrup (HFCS) is significantly cheaper as a sweetener for food and beverage manufacturing than refined sucrose. This has led to sucrose being partially displaced in U.S. industrial food production by HFCS and other non-sucrose natural sweeteners.

Reports in public media have regarded HFCS as less safe than sucrose. However, the most common forms of HFCS contain either 42 percent fructose, mainly used in processed foods, or 55 percent fructose, mainly used in soft drinks, as compared to sucrose, which is 50 percent fructose. Given approximately equal glucose and fructose content, there does not appear to be a significant difference in safety. Clinical dietitians, medical professionals, and the U.S. Food and Drug Administration (FDA) agree that dietary sugars are a source of empty calories associated with certain health problems, and recommend limiting the overall consumption of sugar-based sweeteners.

Cane
Since the 6th century BCE, cane sugar producers have crushed the harvested vegetable material from sugarcane in order to collect and filter the juice. They then treat the liquid, often with lime (calcium oxide), to remove impurities and then neutralize it. Boiling the juice then allows the sediment to settle to the bottom for dredging out, while the scum rises to the surface for skimming off. In cooling, the liquid crystallizes, usually in the process of stirring, to produce sugar crystals. Centrifuges usually remove the uncrystallized syrup. The producers can then either sell the sugar product for use as is, or process it further to produce lighter grades. The later processing may take place in another factory in another country.

Sugarcane is a major component of Brazilian agriculture; the country is the world's largest producer of sugarcane and its derivative products, such as crystallized sugar and ethanol (ethanol fuel).

Beet

Beet sugar producers slice the washed beets, then extract the sugar with hot water in a "diffuser". An alkaline solution ("milk of lime" and carbon dioxide from the lime kiln) then serves to precipitate impurities (see carbonatation). After filtration, evaporation concentrates the juice to a content of about 70% solids, and controlled crystallisation extracts the sugar. A centrifuge removes the sugar crystals from the liquid, which gets recycled in the crystalliser stages. When economic constraints prevent the removal of more sugar, the manufacturer discards the remaining liquid, now known as molasses, or sells it on to producers of animal feed.

Sieving the resultant white sugar produces different grades for selling.

Cane versus beet
It is difficult to distinguish between fully refined sugar produced from beet and cane. One way is by isotope analysis of carbon. Cane uses C4 carbon fixation, and beet uses C3 carbon fixation, resulting in a different ratio of 13C and 12C isotopes in the sucrose. Tests are used to detect fraudulent abuse of European Union subsidies or to aid in the detection of adulterated fruit juice.

Sugar cane tolerates hot climates better, but the production of sugar cane needs approximately four times as much water as the production of sugar beet. As a result, some countries that traditionally produced cane sugar (such as Egypt) have built new beet sugar factories since about 2008. Some sugar factories process both sugar cane and sugar beets and extend their processing period in that way.

The production of sugar leaves residues that differ substantially depending on the raw materials used and on the place of production. While cane molasses is often used in food preparation, humans find molasses from sugar beets unpalatable, and it consequently ends up mostly as industrial fermentation feedstock (for example in alcohol distilleries), or as animal feed. Once dried, either type of molasses can serve as fuel for burning.

Pure beet sugar is difficult to find, so labelled, in the marketplace. Although some makers label their product clearly as "pure cane sugar", beet sugar is almost always labeled simply as sugar or pure sugar. Interviews with the five major beet sugar-producing companies revealed that many store brands or "private label" sugar products are pure beet sugar. The lot code can be used to identify the company and the plant from which the sugar came, enabling beet sugar to be identified if the codes are known.

Mill white
Mill white, also called plantation white, crystal sugar or superior sugar is produced from raw sugar. It is exposed to sulfur dioxide during the production to reduce the concentration of color compounds and helps prevent further color development during the crystallization process. Although common to sugarcane-growing areas, this product does not store or ship well. After a few weeks, its impurities tend to promote discoloration and clumping; therefore this type of sugar is generally limited to local consumption.

Blanco directo
Blanco directo, a white sugar common in India and other south Asian countries, is produced by precipitating many impurities out of cane juice using phosphoric acid and calcium hydroxide, similar to the carbonatation technique used in beet sugar refining. Blanco directo is more pure than mill white sugar, but less pure than white refined.

White refined
White refined is the most common form of sugar in North America and Europe. Refined sugar is made by dissolving and purifying raw sugar using phosphoric acid similar to the method used for blanco directo, a carbonatation process involving calcium hydroxide and carbon dioxide, or by various filtration strategies. It is then further purified by filtration through a bed of activated carbon or bone char. Beet sugar refineries produce refined white sugar directly without an intermediate raw stage.

White refined sugar is typically sold as granulated sugar, which has been dried to prevent clumping and comes in various crystal sizes for home and industrial use:
 * Coarse-grain, such as sanding sugar (also called "pearl sugar", "decorating sugar", nibbed sugar or sugar nibs) is a coarse grain sugar used to add sparkle and flavor atop baked goods and candies. Its large reflective crystals will not dissolve when subjected to heat.
 * Granulated, familiar as table sugar, with a grain size about 0.5 mm across. "Sugar cubes" are lumps for convenient consumption produced by mixing granulated sugar with sugar syrup.
 * Caster (0.35 mm), a very fine sugar in Britain and other Commonwealth countries, so-named because the grains are small enough to fit through a sugar caster which is a small vessel with a perforated top, from which to sprinkle sugar at table. Commonly used in baking and mixed drinks, it is sold as "superfine" sugar in the United States. Because of its fineness, it dissolves faster than regular white sugar and is especially useful in meringues and cold liquids. Caster sugar can be prepared at home by grinding granulated sugar for a couple of minutes in a mortar or food processor.
 * Powdered, 10X sugar, confectioner's sugar (0.060 mm), or icing sugar (0.024 mm), produced by grinding sugar to a fine powder. The manufacturer may add a small amount of anticaking agent to prevent clumping — either corn starch (1% to 3%) or tri-calcium phosphate.

Brown sugar comes either from the late stages of cane sugar refining, when sugar forms fine crystals with significant molasses content, or from coating white refined sugar with a cane molasses syrup (blackstrap molasses). Brown sugar's color and taste become stronger with increasing molasses content, as do its moisture-retaining properties. Brown sugars also tend to harden if exposed to the atmosphere, although proper handling can reverse this.

Dissolved sugar content
Scientists and the sugar industry use degrees Brix (symbol °Bx), introduced by Adolf Brix, as units of measurement of the mass ratio of dissolved substance to water in a liquid. A 25 °Bx sucrose solution has 25 grams of sucrose per 100 grams of liquid; or, to put it another way, 25 grams of sucrose sugar and 75 grams of water exist in the 100 grams of solution.

The Brix degrees are measured using an infrared sensor. This measurement does not equate to Brix degrees from a density or refractive index measurement, because it will specifically measure dissolved sugar concentration instead of all dissolved solids. When using a refractometer, one should report the result as "refractometric dried substance" (RDS). One might speak of a liquid as having 20 °Bx RDS. This refers to a measure of percent by weight of total dried solids and, although not technically the same as Brix degrees determined through an infrared method, renders an accurate measurement of sucrose content, since sucrose in fact forms the majority of dried solids. The advent of in-line infrared Brix measurement sensors has made measuring the amount of dissolved sugar in products economical using a direct measurement.

Consumption
Refined sugar was a luxury before the 18th century. It became widely popular in the 18th century, then graduated to becoming a necessary food in the 19th century. This evolution of taste and demand for sugar as an essential food ingredient unleashed major economic and social changes. Eventually, table sugar became sufficiently cheap and common enough to influence standard cuisine and flavored drinks.

Sucrose forms a major element in confectionery and desserts. Cooks use it for sweetening. It can also act as a food preservative when used in sufficient concentrations. Sucrose is important to the structure of many foods, including biscuits and cookies, cakes and pies, candy, and ice cream and sorbets. It is a common ingredient in many processed and so-called "junk foods".

Nutritional information
Fully refined sugar is 99.9% sucrose, thus providing only carbohydrate as dietary nutrient and 390 kilocalories per 100 g serving (table). There are no micronutrients of significance in fully refined sugar (table).

Metabolism of sucrose
In humans and other mammals, sucrose is broken down into its constituent monosaccharides, glucose and fructose, by sucrase or isomaltase glycoside hydrolases, which are located in the membrane of the microvilli lining the duodenum. The resulting glucose and fructose molecules are then rapidly absorbed into the bloodstream. In bacteria and some animals, sucrose is digested by the enzyme invertase. Sucrose is an easily assimilated macronutrient that provides a quick source of energy, provoking a rapid rise in blood glucose upon ingestion. Sucrose, as a pure carbohydrate, has an energy content of 3.94 kilocalories per gram (or 17 kilojoules per gram).

If consumed excessively, sucrose may contribute to the development of metabolic syndrome, including increased risk for type 2 diabetes, insulin resistance, weight gain and obesity in adults and children.

Tooth decay
Tooth decay (dental caries) has become a pronounced health hazard associated with the consumption of sugars, especially sucrose. Oral bacteria such as Streptococcus mutans live in dental plaque and metabolize any free sugars (not just sucrose, but also glucose, lactose, fructose, and cooked starches) into lactic acid. The resultant lactic acid lowers the pH of the tooth's surface, stripping it of minerals in the process known as tooth decay.

All 6-carbon sugars and disaccharides based on 6-carbon sugars can be converted by dental plaque bacteria into acid that demineralizes teeth, but sucrose may be uniquely useful to Streptococcus sanguinis (formerly Streptococcus sanguis) and Streptococcus mutans. Sucrose is the only dietary sugar that can be converted to sticky glucans (dextran-like polysaccharides) by extracellular enzymes. These glucans allow the bacteria to adhere to the tooth surface and to build up thick layers of plaque. The anaerobic conditions deep in the plaque encourage the formation of acids, which leads to carious lesions. Thus, sucrose could enable S. mutans, S. sanguinis and many other species of bacteria to adhere strongly and resist natural removal, e.g. by flow of saliva, although they are easily removed by brushing. The glucans and levans (fructose polysaccharides) produced by the plaque bacteria also act as a reserve food supply for the bacteria. Such a special role of sucrose in the formation of tooth decay is much more significant in light of the almost universal use of sucrose as the most desirable sweetening agent. Widespread replacement of sucrose by high-fructose corn syrup (HFCS) has not diminished the danger from sucrose. If smaller amounts of sucrose are present in the diet, they will still be sufficient for the development of thick, anaerobic plaque and plaque bacteria will metabolise other sugars in the diet, such as the glucose and fructose in HFCS.

Glycemic index
Sucrose is a disaccharide made up of 50% glucose and 50% fructose and has a glycemic index of 65. Sucrose is digested rapidly, but has a relatively low glycemic index due to its content of fructose, which has a minimal effect on blood glucose.

As with other sugars, sucrose is digested into its components via the enzyme sucrase to glucose (blood sugar). The glucose component is transported into the blood where it serves immediate metabolic demands, or is converted and reserved in the liver as glycogen.

Gout
The occurrence of gout is connected with an excess production of uric acid. A diet rich in sucrose may lead to gout as it raises the level of insulin, which prevents excretion of uric acid from the body. As the concentration of uric acid in the body increases, so does the concentration of uric acid in the joint liquid and beyond a critical concentration, the uric acid begins to precipitate into crystals. Researchers have implicated sugary drinks high in fructose in a surge in cases of gout.

UN dietary recommendation
In 2015, the World Health Organization published a new guideline on sugars intake for adults and children, as a result of an extensive review of the available scientific evidence by a multidisciplinary group of experts. The guideline recommends that both adults and children ensure their intake of free sugars (monosaccharides and disaccharides added to foods and beverages by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates) is less than 10% of total energy intake. A level below 5% of total energy intake brings additional health benefits, especially with regards to dental caries.

Religious concerns
The sugar refining industry often uses bone char (calcinated animal bones) for decolorizing. About 25% of sugar produced in the U.S. is processed using bone char as a filter, the remainder being processed with activated carbon. As bone char does not seem to remain in finished sugar, Jewish religious leaders consider sugar filtered through it to be pareve, meaning that it is neither meat nor dairy and may be used with either type of food. However, the bone char must source to a kosher animal (e.g. cow, sheep) for the sugar to be kosher.

Trade and economics
One of the most widely traded commodities in the world throughout history, sugar accounts for around 2% of the global dry cargo market. International sugar prices show great volatility, ranging from around 3 cents to over 60 cents per pound in the 50 years. About 100 of the world's 180 countries produce sugar from beet or cane, a few more refine raw sugar to produce white sugar, and all countries consume sugar. Consumption of sugar ranges from around 3 kg per person per annum in Ethiopia to around 40 kg in Belgium. Consumption per capita rises with income per capita until it reaches a plateau of around 35 kg per person per year in middle income countries.

Many countries subsidize sugar production heavily. The European Union, the United States, Japan, and many developing countries subsidize domestic production and maintain high tariffs on imports. Sugar prices in these countries have often up to triple the prices on the international market;, with world market sugar futures prices strong, such prices were typically double world prices.

Within international trade bodies, especially in the World Trade Organization (WTO), the "G20" countries led by Brazil have long argued that, because these sugar markets in essence exclude cane sugar imports, the G20 sugar producers receive lower prices than they would under free trade. While both the European Union and United States maintain trade agreements whereby certain developing and least developed countries (LDCs) can sell certain quantities of sugar into their markets, free of the usual import tariffs, countries outside these preferred trade régimes have complained that these arrangements violate the "most favoured nation" principle of international trade. This has led to numerous tariffs and levies in the past.

In 2004, the WTO sided with a group of cane sugar exporting nations (led by Brazil and Australia) and ruled illegal the EU sugar-régime and the accompanying ACP-EU Sugar Protocol, that granted a group of African, Caribbean, and Pacific countries receive preferential access to the European sugar market. In response to this and to other rulings of the WTO, and owing to internal pressures against the EU sugar-régime, the European Commission proposed on 22 June 2005 a radical reform of the EU sugar-régime that cut prices by 39% and eliminated all EU sugar exports.

In 2007, it seemed that the U.S. Sugar Program could become the next target for reform. However, some commentators expected heavy lobbying from the U.S. sugar industry, which donated $2.7 million to U.S. House and Senate incumbents in the 2006 U.S. election, more than any other group of U.S. food-growers. Especially prominent among sugar lobbyists were the Fanjul Brothers, so-called "sugar barons" who made the single individual contributions of soft money to both the Democratic and Republican parties in the U.S. political system.

Small quantities of sugar, especially specialty grades of sugar, reach the market as 'fair trade' commodities; the fair trade system produces and sells these products with the understanding that a larger-than-usual fraction of the revenue will support small farmers in the developing world. However, whilst the Fairtrade Foundation offers a premium of $60.00 per tonne to small farmers for sugar branded as "Fairtrade", government schemes such as the U.S. Sugar Program and the ACP-EU Sugar Protocol offer premiums of around $400.00 per tonne above world market prices. However, the EU announced on 14 September 2007 that it had offered "to eliminate all duties and quotas on the import of sugar into the EU".
