History of Missouri Timeline

European exploration began with the French in the late 1600s, and the region became part of the Louisiana Purchase in 1803. Missouri joined the Union as the 24th state in 1821 under the Missouri Compromise and later served as a contested border state during the Civil War. Today, Missouri is known for its role as the Gateway to the West and its rich cultural and economic heritage. More Less
