A map showing the secession of the Confederate States from the Union, from the secession of South Carolina (December 20, 1860) to the secession of Tennessee (June 8, 1861). The map is color-coded to show the Federal States and territory (including the Union slave-holding States of Missouri, Kentucky, West Virginia, Maryland, and Delaware), and the Confederate States and territories. The map indicated those States and Indian Territory that seceded before April 15, 1861, and those that seceded after the outbreak of the war (Arkansas, Tennessee, Virginia, and North Carolina).
