The Atlantic slave trade, also known as the transatlantic slave trade, was the trade of African people supplied to the colonies of the "New World" that occurred in and around the Atlantic Ocean. It lasted from the 16th century to the 19th century. Most slaves were shipped from West Africa and Central Africa and taken to the New World (primarily Brazil). Generally slaves were obtained through coastal trading with Africans, though some were captured by European slave traders through raids and kidnapping. Most contemporary historians estimate that between 9.4 and 12 million Africans arrived in the New World, although the number of people taken from their homestead is considerably higher. The slave-trade is sometimes called the Maafa by African and African-American scholars, meaning "holocaust" or "great disaster" in Swahili. The slaves were one element of a three-part economic cycle—the Triangular Trade and its Middle Passage—which ultimately involved four continents, four centuries and millions of people.
Slavery was practiced in Africa before the beginning of the Atlantic slave trade. The African slave trade provided a large number of slaves to Europeans and their African agents.
