The Constitution of the Confederate States of America was the supreme law of the Confederate States of America, as adopted on March 11, 1861, and in effect de facto through the conclusion of the American Civil War. The Confederacy also operated under a Provisional Constitution from February 8, 1861 to March 11, 1861. The original Provisional Constitution is currently located at the Museum of the Confederacy in Richmond, Virginia, and differs slightly from the version later adopted. The final, hand-written document is currently located in the University of Georgia archives at Athens, Georgia.
