Madison County, Ohio is a county located in the U.S. state of Ohio with administrative center at London, Ohio. Established during the era of westward expansion following the War of 1812, the county sits within the Columbus metropolitan area and participates in regional networks linking Franklin County, Ohio, Pickaway County, Ohio, Champaign County, Ohio, and Union County, Ohio.

History

Madison County was formed from portions of Franklin County, Ohio and Fayette County, Ohio during the early national period and named in honor of James Madison. Early settlement involved migrants from Pennsylvania, Virginia, and Kentucky who established farms and towns along stagecoach routes connecting Cincinnati, Columbus, Ohio, and Cleveland, Ohio. The county experienced antebellum tensions tied to issues raised by the Missouri Compromise and national debates culminating in the American Civil War, with local volunteers serving in regiments such as those engaged at the Battle of Gettysburg and Battle of Antietam. Postbellum growth tracked the expansion of the Pennsylvania Railroad and the arrival of manufacturing linked to markets in Pittsburgh, Detroit, and Toledo. Twentieth-century developments included participation in New Deal programs like the Works Progress Administration and economic shifts during the Great Depression (United States), world conflicts such as World War I and World War II, and suburbanization influenced by the Interstate Highway System and the growth of Columbus, Ohio.

The county’s topography is modestly rolling, with land use dominated by Corn Belt agriculture and patches of oak-hickory woodland similar to those in Wayne National Forest. Madison County’s climate falls within the Humid continental climate zone, influenced by air masses associated with the Gulf of Mexico and the Laurentian Shield.
