Oswego /ɒsˈwiːɡoʊ/ is a city in Oswego County, New York, United States. The population was 18,142 at the 2010 census. Oswego is located on Lake Ontario in north-central New York and promotes itself as "The Port City of Central New York". It is the county seat of Oswego County.
The city of Oswego is bordered by the towns of Oswego, Minetto, and Scriba to the west, south, and east, respectively, and by Lake Ontario to the north. Oswego Speedway is a nationally known automobile racing facility. The State University of New York at Oswego is located just outside the city on the lake. Oswego is the namesake for communities in Montana, Oregon, Illinois, and Kansas.
The British established a trading post in the area in 1722 and fortified it with a log palisade later called Fort Oswego. The first fortification on the site of the current Fort Ontario was built by the British in 1755 and called the "Fort of the Six Nations."
Fort Ontario was destroyed by the French upon capturing it in the Battle of Fort Oswego, during the French and Indian War. Construction of a second British fort began on the same site in 1759, but Fort Oswego was only used as a cannon emplacement. During the American Revolution, the British abandoned the Fort, and in 1778, American troops destroyed it. In 1782, the British reoccupied Fort Ontario, and didn't forfeit it to the U.S. until 1796, thirteen years after the cessation of hostilities in the Revolution. During the War of 1812, a weaker American garrison at Fort Oswego was overwhelmed by superior British forces, in order to stem the flow of supplies from the interior of New York state. Throughout the 19th Century, the U.S. military maintained a presence at Fort Ontario.
