Missouri and Kentucky were represented by partisan factions adopting the forms of state governments without control of substantial territory or population in either case. The antebellum state governments in both maintained their representation in the Union. Also fighting for the Confederacy were two of the "Five Civilized Tribes" – the Choctaw and the Chickasaw – in Indian Territory and a new, but uncontrolled, Confederate Territory of Arizona. Efforts by certain factions in Maryland to secede were halted by federal imposition of martial law; Delaware, though of divided loyalty, did not attempt it. A Unionist government was formed in opposition to the secessionist state government in Richmond and administered the western parts of Virginia that had been occupied by Federal troops. The Restored Government of Virginia later recognized the new state of West Virginia, which was admitted to the Union during the war on June 20, 1863, and relocated to Alexandria for the rest of the war.
