Before the results of the election of 1860, a special session of the south carolina was called in the event that abraham lincoln won the presidential election.

An official secession convention met in South Carolina following the November 1860 election of Abraham Lincoln as President of the United States, on a platform opposing the expansion of slavery into U.S. territories

Explanation:

The population of all of South Carolina, who saw the election of Lincoln as an attack on the ‘guarded’ institution of slavery, was completely not interested in an alliance with those who intended to rid them of it. They regarded their slaves as property and believed that they had the same constitutional right to take this property to common territories, as the northern settlers did, who drive horses and mules with them. Lincoln, becoming president, intended to strip them of this privilege; in other words, he was going to deny them equal rights. In his speeches, he condemned slavery; considering it evil, he had to fight it where it existed, and unconditionally limit its distribution.  

In the wake of tremendous enthusiasm, the people of South Carolina almost unanimously demanded the separation of their state from the Federal Union. Its authorities reacted immediately. A convention was convened, a secession decree was adopted, and the South Carolina Declaration of Independence was proclaimed.
