1. On June 11, 1776, the Third Provincial Congress of South Carolina ratified the Constitution of South Carolina, making it the first of the original thirteen states to adopt a new constitution after the Declaration of Independence was signed the previous year.

2. In 1832, President Andrew Jackson signed the Nullification Proclamation, which declared that the federal government had the authority to enforce federal law in South Carolina and other states that opposed the Tariff of 1828. This proclamation was a response to South Carolina's attempts to nullify the tariff and threatened secession from the Union.

3. On June 11, 1864, General William T. Sherman's Union forces attacked Confederate troops in the Battle of Trevilian Station, one of the largest cavalry engagements of the Civil War. The battle was fought in central Virginia, but many soldiers from both sides were from South Carolina.

4. In 1963, Governor George Wallace of Alabama gave his infamous "Segregation now, segregation tomorrow, segregation forever" speech at the Statehouse in Montgomery. This speech was a rallying cry for opponents of civil rights, including many white South Carolinians who resisted the desegregation of schools, housing, and public spaces.

5. On June 11, 1991, the South Carolina General Assembly voted to remove the Confederate battle flag from atop the Statehouse dome in Columbia and install it at a Confederate monument on the Statehouse grounds. This compromise solution was intended to defuse tensions between those who saw the flag as a symbol of heritage and those who saw it as a symbol of racism and oppression. The flag remained on the Statehouse grounds until it was removed entirely in 2015, following the Charleston church shooting.
