Union County, Ohio

Union County, Ohio is a county in the U.S. state of Ohio with its county seat at Marysville. The county lies within the Columbus metropolitan area and is intersected by transportation corridors linking Columbus, Ohio, Cincinnati, Cleveland, Ohio, Dayton, Ohio, and Toledo, Ohio. Historically agricultural and increasingly industrial and suburban, the county has connections to national developments such as the National Road (United States), the Great Black Swamp, the Ohio and Erie Canal, and midwestern migration routes.

History

The area now comprising the county was originally inhabited by Indigenous peoples including the Shawnee, Miami, and Wyandot before European-American settlement associated with the Northwest Territory and the Treaty of Greenville. Following the Louisiana Purchase era migrations and settlement patterns tied to the American Revolutionary War land grants, the county was established in 1820 during a period of Ohio county formations alongside neighbors formed from land redistributed after the Treaty of Fort Industry. Early town development reflects influences from pioneers who traveled along routes related to the Great Wagon Road, the National Road (United States), and later the expansion of the Amtrak corridors. Agricultural production in the 19th century connected to markets via the Ohio and Erie Canal and the National Road, while Civil War enlistments tied local communities to units such as those at the Battle of Gettysburg, the Siege of Vicksburg, and the Battle of Antietam. Industrialization in the 20th century brought manufacturing related to companies with headquarters near Columbus, Ohio and supply chains linked to the Interstate Highway System, especially Interstate 71.
