Atlantic Slave Trade

The forced transportation of an estimated 12.5 million Africans across the Atlantic to the Americas as enslaved labor over more than three centuries, one of history's greatest crimes against humanity.

Key Figures

Preceding Causes

European colonial plantation economies (sugar, tobacco, cotton) demanding massive labor, Portuguese exploration of the West African coast, catastrophic decline of indigenous American populations from Old World diseases, existing West African slave trading networks, and the profit motive of the triangular trade.

Historical Consequences

Devastated West and Central African societies through depopulation and political destabilization, built the plantation economies of the Americas (particularly the Caribbean, Brazil, and the US South), generated enormous wealth for European trading nations, and created the African diaspora whose cultural contributions transformed the Americas.
