What states seceded after the civil war When did they secede?

After the Civil War, no states seceded; the states that had previously seceded did so before the war began, primarily from 1861 to 1865. The eleven Confederate states that seceded were South Carolina (December 20, 1860), Mississippi (January 9, 1861), Florida (January 10, 1861), Alabama (January 11, 1861), Georgia (January 19, 1861), Louisiana (January 26, 1861), Texas (February 1, 1861), Virginia (April 17, 1861), Arkansas (May 6, 1861), Tennessee (June 8, 1861), and North Carolina (May 20, 1861). After the war ended in 1865, these states were gradually readmitted to the Union during the Reconstruction era.
