U.S. Congress splits the Mississippi Territory, creating the Alabama Territory

Federal statutes enacted on March 1 and 3, 1817, established the plan to divide the Mississippi Territory into the State of Mississippi and the Alabama Territory.

The U.S. Congress passed two interdependent acts on March 1 and 3, 1817, to split the Mississippi Territory. These acts designated the eastern half as the Alabama Territory and the western half for statehood. The legislation was contingent on the western part forming a constitution, delaying the effective date of the Alabama Territory's creation.
