Charleston was a central hub in the domestic slave trade, which in the wake of a fifty-year-old federal ban on international trading now thrived and accounted for much of the city’s wealth. The “Slave Schedule” of the 1860 U.S. Census listed 440 South Carolina planters who each held one hundred or more enslaved Blacks within a single district, this when the average number owned per slaveholding household nationwide was 10.2. In 1860, the South as a whole had 3.95 million slaves.
