After the election of Abraham Lincoln in 1860, the state of Florida seceded from the United States, and within a month had become a one of the founding members of the Confederate States of America. Throughout the Civil War, Florida played an important role as the main supplier of food and other goods for the Confederate soldiers, as it's vast coastline made it difficult for the Union troops to block movements. The state saw only one major battle, the Battle of Olustee, though there were a few minor skirmishes throughout the war. On May 20th, 1865, the Emancipation Proclamation was read during a ceremony in Tallahassee - thus ending slavery in the state. It was re-admitted to the Union on July 25, 1868.
