Chautauqua County History

Long part of the homeland of the Seneca Nation, one of the six nations of the Iroquois Confederacy, Chautauqua County was organized by the state legislature during the development of western New York after the American Revolutionary War. It was officially separated from Genesee County on March 11, 1808. This partition was performed under the same terms that produced Cattaraugus and Niagara counties. The partition was done for political purposes, but the counties were not properly organized for self-government, so they were all administered as part of Niagara County.

On February 9, 1811, Chautauqua was completely organized, and its separate government was launched. This established Chautauqua as a county of 1,100 square miles (2,850 square km) of land. Chautauqua has not been altered since.
