Territorial evolution of the Confederate States

The Confederate States of America was created on February 8, 1861, by representatives from six states that had recently declared their secession from the United States of America, starting with South Carolina on December 20, 1860. After the start of the American Civil War on April 12, 1861, between the two countries, five additional states would secede, and representatives of two others would gain admittance to the Confederacy.
