This book explores Africa's involvement in the Atlantic world from the fifteenth through the eighteenth centuries. It focuses especially on the causes and consequences of the slave trade, in Africa, in Europe, and in the New World. Prior to 1680, Africa's economic and military strength enabled African elites to determine how trade with Europe developed. Thornton examines the dynamics which made slaves so necessary to European colonizers.

This edition contains a new chapter extending the story into the eighteenth century.
