The first state to secede from the Union in 1860 was South Carolina.

Explanation:

South Carolina was the first state to separate from the Union, on December 20, 1860, after the election of Abraham Lincoln, to found the Confederate States of America. The Civil War began in South Carolina on April 12, 1861, when Confederate troops invaded Fort Sumter. After the end of the war, the state would be reinstated again in the Union, on June 25, 1868.
