In what way did the American Revolution affect the slave trade in South Carolina? The slave trade increased immediately afterward. The slave trade was prohibited for six years. The slave trade was burdened by growing debt. The slave trade decreased and eventually disappeared.
The slaves that were in America were convinced by the British to join the British so they could help in war. Mostly they were put as nurse and other slave jobs. The slaves were offered freedom from the British, that is why they joined the British.
