Some Southerners had threatened secession at the prospect of Lincoln's election. Now the moment of decision had arrived. On December 20, 1860, a South Carolina convention voted unanimously for secession; in short order Alabama, Mississippi, Florida, Georgia, Louisiana, and Texas followed. On February 4, delegates from these seven states met in Montgomery, Alabama, and established the Confederate States of America.
