which new state was formed at the beginning of the civil war
Confederate States of America 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 later recognized the new state of West Virginia, which was admitted to the Union during the war on June 20, 1863, and re-located to Alexandria for the rest of the war.[9]
Mississippi in the American Civil War Mississippi was the second southern state to declare its secession from the United States of America, on January 9, 1861. It joined with six other southern slave-holding states to form the Confederacy on February 4, 1861. Mississippi's location along the lengthy Mississippi River made it strategically important to both the Union and the Confederacy; dozens of battles were fought in the state as armies repeatedly clashed near key towns and transportation nodes.
