Ohio became a state in 1803, but it was not until 1953 that Congress formally admitted it into the Union, retroactive to March 1, 1803. After the state capital shifted from Chillicothe to Zanesville and back again, the Ohio General Assembly eventually designated the new city of Columbus as the seat of government in 1816. A free state, Ohio remained loyal to the Union during the Civil War.
