Map of Western Reserve, Ohio 1826

Ohio, often referred to as the “Buckeye State,” occupies a pivotal position in the nation’s development, from the prehistoric mound-building societies that first inhabited the region to its role as an industrial powerhouse in the modern United States. Bordered by the Great Lakes to the north and the Ohio River to the south, Ohio has long served as a crossroads of culture, commerce, and politics. The state’s storied past includes influential Native American civilizations, a central part in westward expansion under the Northwest Ordinance, key participation in the Civil War and Underground Railroad, and ongoing contributions to America’s economic and political life.
