dec 20, 1860 - South Carolina secedes from Union

Description:

The South regarded slavery as crucial to its plantation economy, society and traditions. As early as 1835, when the postmaster in Charleston, South Carolina, found abolitionist material in the mail, he refused to deliver it and it was burned in public on a bonfire.
