Charleston and the Slave Trade: Why the Port Mattered

Charleston is remembered today for its pastel houses, church steeples, and cobblestone streets. It was also one of the most important ports in the history of American slavery. Roughly four in ten enslaved Africans brought to North America arrived through Charleston, and after the international trade was outlawed, the city became a major center of the domestic trade that sold enslaved people to the expanding cotton lands of the South. This article explains that history and points to the places in Charleston where you can learn more.

Charleston’s role in the Atlantic slave trade

Eighteenth-century South Carolina was the continent’s leading importer of enslaved people, receiving approximately 100,000 Africans over the course of the century, according to the South Carolina Encyclopedia. The International African American Museum states that more than 40 percent of the Africans forced to North America arrived in Charleston. Other commonly cited estimates run a little lower, in the range of 35 to 40 percent, depending on the records and methods used. Every version of the figure points to the same conclusion: Charleston was the single most important point of arrival for enslaved Africans in North America.

Gadsden’s Wharf

In the final stages of the Atlantic trade to Charleston, slave ships docked at Gadsden’s Wharf on the Cooper River waterfront. The site is now home to the International African American Museum at 14 Wharfside Street, which opened there so that the story of arrival could be told at the place where so many people first set foot on American soil.

The 1808 deadline and the final surge of imports

At the 1787 Constitutional Convention, delegates reached a compromise that guaranteed the international slave trade could continue for twenty years. Federal prohibition took effect in 1808. South Carolina had reopened its own international trade in 1803, and in the five years before the federal ban, almost forty thousand Africans entered the port of Charleston. The approaching deadline produced a surge of imports rather than a slowdown.

The domestic slave trade after 1808

Ending the international trade did not end the buying and selling of human beings. It turned the trade inward. Enslaved people were sold within the United States and moved, often over great distances and often away from their families, to work on the cotton and sugar lands that were opening in the Deep South and Texas. By the 1820s, South Carolina had become a net exporter of enslaved people.

Charleston became one of the major collecting and selling centers of this domestic trade. For decades, enslaved people were sold publicly around the Old Exchange building on the waterfront. In 1856 the city banned public auctions there, and the business moved into enclosed marts on Chalmers, State, and Queen streets. Ryan’s Mart, whose last surviving building is now the Old Slave Mart Museum, is the best-known of them. Conservative estimates suggest that around 10,000 people were sold through Ryan’s Mart, and that some were sent as far as Texas. Read more in our history of the Old Slave Mart and Ryan’s Mart.

What this history means for visitors today

Many visitors arrive in Charleston expecting architecture, food, and beaches, and they find them. They also walk streets where this history happened, often without knowing it. Learning about the slave trade does not require giving up the rest of the trip; it deepens it. The Old Slave Mart Museum places the domestic trade inside a real building. The International African American Museum tells the story of arrival and of the descendants who built lives, culture, and communities in Charleston and the surrounding Lowcountry. The College of Charleston’s Avery Research Center preserves and interprets African American history in the region.
