This poster is an advertisement for a sale of captive people, held in 1760 in Charleston, South Carolina, United States. The poster would have been displayed weeks before the sale, on public bulletin boards, in the windows of local businesses, and in newspapers and pamphlets.

Enslaved people from this ship (the Bance-Island) would have been of particular interest to South Carolina plantation owners, because they hailed from the "Windward and Rice Coasts." The Windward and Rice Coasts lie along Africa's central Atlantic shoreline, and include the present-day nations of Sierra Leone, Liberia, Cote d'Ivoire, Ghana, Togo, and Benin.

Africans from the Rice Coast were valuable to South Carolina farmers because they were familiar with growing and harvesting the colony's cash crops, rice and indigo. Human traders who saw African farmers cultivate rice along the Rice Coast immediately recognized the potential for growing the crop in the "Low Country" of South Carolina, which shares a similar geography and climate: flat, tidal streams and flood plains; barrier islands; humid summers; and forested inland areas.

African captives brought to colonial America helped establish the rice-based economy of South Carolina. They knew how to regulate irrigation with levees, flood gates, and drains. Their knowledge contributed to the shift of rice cultivation from inland swamps to tidal flood plains. By the time of the American Revolution, the crop was second only to tobacco in terms of economic value to the new nation.

Enslaved people were also instrumental in indigo production. Indigo is native to tropical Africa, and communities along the Windward and Rice Coasts had hundreds of years' experience cultivating the plant and producing its valuable dye. In particular, Africans knew the complex chemical process needed to transfer the blue color to fabric—the dye is not water-soluble. In 1744, Eliza Pickney, a white woman, and unnamed African captives cultivated a new strain of indigo that flourished in South Carolina. It soon became the colony's other cash crop.

Captives sold at Charleston auctions like this one were immediately put to work, mostly in indigo and rice plantations. The work was exhausting—backbreaking labor in flooded fields susceptible to harmful microbes and mosquitoes. More than a third of enslaved children died before their first birthday, mostly due to malaria and malnutrition.

Colonial travelers to South Carolina's plantations called the rice and indigo fields "charnel houses."


  • More slaves were imported to colonies in the American South (such as South Carolina) than the North. Why?

    The South had a much larger agricultural economy. Slaves were in much higher demand in rural plantation communities in the South than urban or industrial centers in the North.

  • In the 1760s, South Carolina plantation owners were, on average, wealthier than landowners in other American colonies. What were the other 12 colonies?

    The British colonies that eventually became the United States were:
    • New Hampshire
    • Massachusetts Bay (later, Massachusetts and Maine)
    • Rhode Island
    • Connecticut
    • New York
    • New Jersey
    • Pennsylvania
    • Delaware
    • Maryland
    • Virginia (later, Virginia, Kentucky, and West Virginia)
    • North Carolina (later, North Carolina and Tennessee)
    • South Carolina
    • Georgia (later, Georgia, Alabama, and Mississippi)

  • Busy as Charleston's slave market was, it was dwarfed by the slave trade in the Caribbean. In what industry do you think Caribbean slaves worked?

    Like slaves in mainland North America, slaves usually worked in agriculture, mostly on sugar cane plantations.

  • The journey from Africa to the Americas is known as the Middle Passage of the Atlantic slave trade, often called the "Triangle Trade." Where were the other two "passages," and what was their primary cargo?

    The first leg of the Triangle Trade brought ships and supplies to West Africa from Europe. Loaded with slaves, these ships crossed the Atlantic "Middle Passage." The last leg of the Triangle Trade brought goods and raw materials from the Americas (such as rice from the Carolinas, sugar from the Caribbean, or ore from South America) to Europe.

  • Geographer Bob Janiskee calls Charleston's Sullivan's Island a "macabre Ellis Island." Why?

    Ellis Island, in New York Harbor near the Statue of Liberty, was the gateway to the United States for millions of European immigrants. Ellis Island is a symbol of the American Dream of freedom, independence, and opportunity. Although thousands of Africans became African-Americans on Sullivan's Island, their journeys were a nightmarish parody of freedom, independence, and opportunity.

  • Fast Facts

    • Until the early 1800s, many English-speaking areas used the "long s" in written communication. Long s letters were loosely based on ancient Roman writing, and often looked like lower-case fs. The long s was not always used. In this advertisement, "Tuesday" and "Ashley Ferry" look like "tuefday" and "Afhley-ferry." "Charles-Town," however, looks familiar.
    • Charleston, South Carolina, was named by British colonists in honor of their king, Charles II, in 1670. The city was officially known as Charles-Town until 1783, after the American Revolution. This slave sale took place in 1760, when South Carolina was still a British colony.
    • Charleston (or Charles-Town) was the busiest, most lucrative slaving port in colonial America. Between 1706 and 1775, about 98,000 slaves were imported to Charleston. By 1740, well before this sale, more than half of South Carolina's population was made up of African and West Indian slaves.
    • Charleston was an ideal port for international slave traders. Unlike ports in the shallow, winding Chesapeake Bay (such as Baltimore, Maryland, and Norfolk, Virginia), Charleston was a deep, natural harbor located directly on the Atlantic coast. In addition, Charleston was flanked by two broad rivers, the Ashley and the Cooper. Large ships could easily navigate and dock, and smaller boats could take purchased slaves to locations further inland. This slave sale, for instance, was scheduled at the large ferry on the Ashley River in Charleston Harbor.
    • This slave ship, the Bance-Island, was named for its place of origin in Sierra Leone. Bance (now called Bunce) was in many ways Charleston's twin on Africa's Rice Coast. It was a major slaving port, sitting in West Africa's largest natural harbor and at the mouth of a major river (the Sierra Leone). Unlike other African slaving ports (such as James Island, Gambia, or Accra, Ghana), Bunce did not supply many slaves to the thriving plantations in South America, the Caribbean, or the Chesapeake. Nearly all slaves shipped from Bunce went to Charleston.
    • Henry Laurens, one of the businessmen publicizing this sale, had a unique connection to Bunce. Richard Oswald, the British executive who managed the slave trade at Bunce, was his business partner. Three or four times a year, Oswald would send a shiploaded with ivory, camwood (an exotic lumber), and slavesto Laurens in Charleston. Laurens would sell the goods and reload the ship. If loaded with rice, South Carolina's leading cash crop, the ship would sail for London, England. If loaded with shipping supplies (masts and sails), it sailed directly back to Bunce.
    • Laurens was one of the wealthiest plantation owners and slave traders in South Carolina. South Carolina landowners were generally worth more than six times their fellow landowners in the other American colonies.
    • Laurens and other slave traders sold entire shiploads of slaves (about 250-300 people) within one or two days during the peak trading period between May and October. No deals were struck before the day of the sale, and discounts were not offered for bulk purchases. Discounts were offered for prompt payment, however. (Buyers, who usually had four to six months to pay for their human purchases, rarely paid cash up-front.)
    • Slaves sold for varied prices, depending on their health, age, and sex. Slave traders could sell healthy young mentheir most valuable commodityfor as much as 200 pounds sterling (about $25,000 in today's money). The local trader (Laurens, for instance) made about 10%-15% of that, and the rest went to the trading company (Oswald, back in Bunce).
    • As this poster advertises, slave traders took the "utmost care" to prevent smallpox from reaching their human cargo. Ships like the Bance-Island regularly quarantined slaves on Sullivan's Island in Charleston Harbor. Today, as many as 40% of African Americans trace their ancestry to Charleston, leading geographer Bob Janiskee to call Sullivan's Island a "macabre Ellis Island."
    • This poster actually documents South Carolina's "second wave" of slave trading. The "first wave" primarily imported slaves from Angola and Kongo (today, areas of the Republic of Congo, the Democratic Republic of Congo, Angola, and Gabon). These slaves were responsible for clearing land and tending to the livestock of "absentee landlord" owners in the "Wild West" of South Carolina. In fact, some historians say a racist, derisive term for these slaves created one of the most familiar, respected words for their responsibilities. They were "boys" who tended cattle: cowboys.
