The transatlantic slave trade involved the capture and transportation of millions of Africans across the Atlantic for a period of approximately four hundred years. European and New World merchants, traders, and ship captains were behind much of the organization of this huge forced migration. They also captured and loaded Africans onto slave ships themselves via raids, warfare, or trade. However, the traffic would not have evolved as it did had they failed to rely on a series of mechanisms of enslavement indigenous to Africa. Some of these mechanisms included judicial proceedings, debts, pawning, trickery, kidnapping, and, of course, warfare. Each of them had an impact on Africa and her children, both those who stayed behind and those scattered across the Atlantic. Nevertheless, these mechanisms helped sustain the traffic as a long-lasting and complex historical event.
