The Confederate States Army was the army of the Confederate States of America (or "Confederacy") while the Confederacy existed during the American Civil War. On February 8, 1861, delegates from the seven Deep South states which had already declared their secession from the United States of America adopted the Provisional Constitution of the Confederate States of America. On February 28, 1861, the Provisional Confederate Congress established a provisional volunteer army and gave control over military operations and authority for mustering state forces and volunteers to the President of the Confederate States of America. On March 1, 1861, Provisional Confederate President Jefferson Davis, on behalf of the Confederate States government, assumed control of the military situation at Charleston, South Carolina where state militia were threatening to seize Fort Sumter from the small United States Army garrison. On March 6 and 9, 1861, the Provisional Confederate Congress passed additional military legislation and established a more permanent Confederate States Army (CSA).
