Historical associations with the Atlantic slave trade led to the region becoming known as the Slave Coast. As in many other regions across Africa, powerful indigenous kingdoms along the Bight of Benin relied heavily on a long-established slave trade that expanded greatly after the arrival of European powers and became a global trade with the colonization of the Americas. Estimates from the 1640s suggest that Benin took in 1200 slaves a year. Restrictions made it hard for slave volume to grow until new states and different routes began to make an increase in slave trade possible.
