What were two ways that South Carolina participated in the events leading to the war?

South Carolina played a pivotal role in the events leading to the Civil War by becoming the first state to secede from the Union on December 20, 1860, following the election of Abraham Lincoln. Additionally, the state was the site of the first military conflict of the war when Confederate forces fired on Fort Sumter on April 12, 1861, marking the official start of hostilities between the North and South. These actions highlighted South Carolina's commitment to the secessionist cause and its leadership in the movement against federal authority.
