This South Carolina history timeline traces the state’s role as a center of colonial wealth built on slavery, its decision to lead Southern secession, and its experience as the flashpoint for the American Civil War.
Colonial Prosperity and Slavery’s Expansion
South Carolina was founded in 1670 as an English colony, with Charleston rapidly becoming a major commercial center. The colony’s initial economy relied on trade in deerskins and other exports, but by the 1690s, large-scale rice cultivation emerged as the dominant enterprise. Rice plantations required enormous labor inputs, and planters imported enslaved African people by the thousands to work the fields. South Carolina became the most slave-dependent colony in North America, with enslaved people eventually outnumbering free settlers. The wealth generated by rice exports funded the construction of grand mansions, churches, and civic institutions in Charleston, creating an elite planter class whose power extended into state and national politics. This economic foundation was built entirely on human slavery and the exploitation of African peoples.

Revolution and Early National Period
South Carolina played a significant role in the American Revolution, hosting major battles and producing leaders like Francis Marion, the “Swamp Fox.” After independence, South Carolina ratified the U.S. Constitution on May 23, 1788, as the eighth state. In the early 19th century, as the cotton gin revolutionized the profitability of cotton cultivation, South Carolina deepened its dependence on slavery. The state’s political leaders, including John C. Calhoun, became vocal advocates for slavery and states’ rights, viewing federal regulation of slavery as an unconstitutional intrusion on state sovereignty.
Secession and the Civil War
The election of Abraham Lincoln in November 1860 triggered South Carolina’s decisive action. On December 20, 1860, the state became the first to secede from the Union, formally withdrawing over disputes regarding slavery and states’ rights. South Carolina’s secession set off a chain reaction, as other Southern states followed. The crisis escalated when Confederate forces, seeking to take over federal property in South Carolina, attacked Fort Sumter in Charleston Harbor on April 12, 1861. This bombardment marked the opening military engagement of the American Civil War. The war lasted four years, resulted in Confederate defeat, and left South Carolina devastated. The subsequent Reconstruction period imposed federal oversight and attempted to reshape Southern society, though many of the promised reforms were not sustained.
