Missouri secession

During the lead-up to the American Civil War, the proposed secession of Missouri from the Union was controversial because of the state's disputed status. The Missouri state convention voted in March 1861, by 98-1, against secession, and was a border state until abolishing slavery in January 1865. Missouri was claimed by both the Union and the Confederacy, had two rival state governments,, and sent representatives to both the United States Congress and the Confederate Congress.
