The Atlantic slave trade or transatlantic slave trade took place across the Atlantic Ocean from the 15th through the 19th centuries. The vast majority of those who were enslaved and transported to the New World, mainly on the triangular trade route and its Middle Passage, were Africans from the central and western parts of the continent who had been sold by other West Africans to Western European slave traders. The Atlantic Slave Trade was the result of, among other things, labor shortage. The first slaves to arrive as part of a labor force in the New World reached the island of Hispaniola (now Haiti and the Dominican Republic) in 1502. Cuba received its first four slaves in 1513. Jamaica received its first shipment of 4000 slaves in 1518.[97] Slave exports to Honduras and Guatemala started in 1526.
