Definition
The transatlantic slave trade was the forced capture, sale, and shipment of African people across the Atlantic Ocean to be enslaved in the Americas. It operated from the 16th century into the 19th, and during that span an estimated twelve million or more Africans were carried into bondage.
It was one of the largest forced migrations in human history. The people taken were not commodities or cargo; they were human beings — families, communities, and individuals — violently torn from their homelands.
Why it matters
How it works
The trade followed a triangular pattern. European ships carried manufactured goods to the African coast, exchanged them for captured people, transported those people across the Atlantic, and returned to Europe with plantation produce. Each leg generated profit, and the system's brutality was treated by traders as a cost of doing business.
Capture itself relied on raiding, warfare, and coercion in Africa. Once enslaved, people were branded, sold, and worked under the threat of violence — a system designed to deny them freedom, family, and humanity.
