The answer is: to uphold the rights of property owners
On December 20, 1860, the Assembly of Representatives of South Carolina approved the secession of the Federal Union.
In that declaration it was stated that the state of South Carolina would fight for the rights of the slaves, that is, in that state, slavery would continue.
This Declaration in favor of slavery was given in this state a month and a half after Abraham Lincoln's victory in the presidential election of 1860 because southern slavers were panicked with the election of Lincoln.
