Explanation:

When Abraham Lincoln is elected president in 1860, South Carolina is the first state to secede.  The main concern of the southern states was the issue of slavery, and Lincoln was opposed to it.  There were many other causes that led to the secession, such as the rise of the Abolitionist Movement and the Compromise of 1850, but Lincoln's victory was the immediate cause.  After South Carolina, six other states followed and began forming the Confederacy.  The Civil War officially breaks out with the attack on Fort Sumter on April 12, 1861.
