On December of 1860, South Carolina voted, in a special state convention, to secede from the Union.

South Carolina approved the "Declaration of the Immediate Causes Which Induce and Justify the Secession of South Carolina from the Federal Union " on December 24, 1860. It affirmed that it would fight for the rights of the slaves' owners but denied the right of the Northern states to reject the Law of Fugitive Slaves, alleging that they did not comply with their federal obligations.

The declaration ends by stating South Carolina's secession from the United States.
