Umwalla said that strangers took him away in ropes to be sold when he was 10, and he never saw his family again. The Trans-Atlantic Slave Trade was the largest forced migration of people in world history. For 350 years, slave traders raided African villages, capturing millions of men, women, and children. Many were taken to America and sold to plantation owners in the American South. In 1807, it became illegal to import enslaved Africans into the United States, but many Americans continued to profit from the Trans-Atlantic Slave Trade. In 1858, the owners of the yacht Wanderer changed it into a slave ship and sent it to the coast of Africa to buy captives to sell in Georgia.
