The Topeka Constitutional Convention met from October 23 to November 11, 1855, in Topeka, Kansas Territory, in a building afterwards called Constitution Hall. It drafted the Topeka Constitution, which banned slavery in Kansas, though it would also have prevented free blacks from living in Kansas. The convention was organized by Free-Staters to counter the pro-slavery Territorial Legislature elected March 5, 1855, in polling tainted significantly by electoral fraud and the intimidation of Free State voters.
