mississippi was the first state to secede from the union
Mississippi was the second southern state to declare its secession from the United States of America, on January 9, 1861. It joined with six other southern slave-holding states to form the Confederacy on February 4, 1861. Mississippi's location along the lengthy Mississippi River made it strategically important to both the Union and the Confederacy; dozens of battles were fought in the state as armies repeatedly clashed near key towns and transportation nodes.
