How were the social structures of Africa altered as a result of the forced migration of Africans destined for slavery in the Americas?

This African chant mourns the loss of Olaudah Equiano, an eleven-year-old boy who, in 1755, was kidnapped from his home in what is now Nigeria. He was purchased by a captain in the British Royal Navy, was later sold to a Quaker merchant in the Caribbean, and in 1766 bought his freedom. He wrote his autobiography in 1789, giving readers a rare glimpse of how it felt to be kidnapped from home in Africa and to survive onboard a slave trader's ship. In his autobiography, Equiano wrote, "There are few events in my life that have not happened to many." By this, he referred to the kidnapping of millions of free West Africans by slave traders, who then sold them to wealthy merchants and plantation owners.
