In addition to voting for seccession, what else did south carolina propose at its state convention held following the election of 1860?

The force of events moved very quickly upon the election of Lincoln. South Carolina acted first, calling for a convention to SECEDE from the Union. State by state, conventions were held, and the CONFEDERACY was formed.

Within three months of Lincoln's election, seven states had seceded from the Union. Just as Springfield, Illinois celebrated the election of its favorite son to the Presidency on November 7, so did Charleston, South Carolina, which did not cast a single vote for him. It knew that the election meant the formation of a new nation. The Charleston Mercury said, "The tea has been thrown overboard, the revolution of 1860 has been initiated."

definitely a for sure. ill see and update if i get the answer
