Florida participated in the American Civil War as a member of the Confederate States of America. It had been admitted to the United States as a slave state in 1845. In January 1861, Florida became the third Southern state to secede from the Union after the November 1860 presidential election victory of Abraham Lincoln. It was one of the initial seven slave states which formed the Confederacy on February 8, 1861, in advance of the American Civil War.
Florida had by far the smallest population of the Confederate states with about 140,000 residents, nearly half of them enslaved people. Florida sent around 15,000 troops to the Confederate army, the vast majority of which were deployed elsewhere during the war. The state's chief importance was as a source of cattle and other food supplies for the Confederacy, and as an entry and exit location for blockade-runners who used its many bays and small inlets to evade the Union Navy. One thousand and forty-four African Americans from Florida served in the Union Army.
