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.
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.
Spanish Colonization of the Americas
Following Columbus's 1492 voyage, Spain conquered and colonized vast territories in the Americas, destroying the Aztec and Inca empires, subjugating indigenous populations, and extracting enormous mineral wealth.
Age of Exploration
European maritime nations launched expeditions that mapped the globe, connected continents, and transformed world trade, culture, and power dynamics between 1400–1600.
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.
