Oswego County, located in the state of New York, has a rich history that spans over centuries. The region was originally inhabited by Native American tribes, such as the Iroquois and the Algonquin people, who relied on the area's abundant natural resources for their sustenance and trade.

The arrival of Europeans in the 17th century brought significant changes to the area. French explorers were the first to discover the region, followed by Dutch and English settlers. The site where the city of Oswego now stands became an important trading post, attracting fur traders and leading to the establishment of Fort Oswego in 1727. The fort played a crucial role in the French and Indian War, as well as the American Revolution.

During the early 19th century, the construction of the Erie Canal brought economic prosperity to Oswego County. The canal connected the Great Lakes to the Hudson River, making Oswego a vital transportation hub for goods and people. The development of the canal also fueled the growth of industry in the county, particularly in the city of Oswego, which became a major center for shipping, manufacturing, and commerce.

In the 20th century, Oswego County's economy shifted towards manufacturing, particularly in the steel and automotive industries. The construction of power plants along the Oswego River, including the James A. FitzPatrick Nuclear Power Plant, brought new job opportunities and bolstered the county's energy sector.
