The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people, mainly to the Americas. The slave trade regularly used the triangular trade route and its Middle Passage, and existed from the 16th to the 19th centuries. The vast majority of those who were enslaved and transported in the transatlantic slave trade were people from Central and West Africa, who had been sold by other West Africans to Western European slave traders, who brought them to the Americas. The South Atlantic and Caribbean economies were particularly dependent on labour for the production of sugarcane and other commodities. This was viewed as crucial by those Western European states which, in the late 17th and 18th centuries, were vying with each other to create overseas empires.
The Portuguese, in the 16th century, were the first to engage in the Atlantic slave trade. In 1526, they completed the first transatlantic slave voyage to Brazil, and other Europeans soon followed. Shipowners regarded the slaves as cargo to be transported to the Americas as quickly and cheaply as possible, These slaves were managed by a factor, who was established on or near the coast to expedite the shipping of slaves to the New World. Slaves were imprisoned in a factory while awaiting shipment. Current estimates are that about 12 million to 12.8 million Africans were shipped across the Atlantic over a span of 400 years, Near the beginning of the 19th century, various governments acted to ban the trade, although illegal smuggling still occurred. In the early 21st century, several governments issued apologies for the transatlantic slave trade.
Background Â
Atlantic travel  Â
The Atlantic slave trade developed after trade contacts were established between the "Old World" Â and the "New World" . For centuries, tidal currents had made ocean travel particularly difficult and risky for the ships that were then available, and as such there had been very little, if any, maritime contact between the peoples living in these continents. In the 15th century, however, new European developments in seafaring technologies resulted in ships being better equipped to deal with the tidal currents, and could begin traversing the Atlantic Ocean; the Portuguese set up a Navigator's School . Between 1600 and 1800, approximately 300,000 sailors engaged in the slave trade visited West Africa. In doing so, they came into contact with societies living along the west African coast and in the Americas which they had never previously encountered. Historian Pierre Chaunu termed the consequences of European navigation "disenclavement", with it marking an end of isolation for some societies and an increase in inter-societal contact for most others.
African slavery  Â
Slavery was prevalent in many parts of Africa for many centuries before the beginning of the Atlantic slave trade. There is evidence that enslaved people from some parts of Africa were exported to states in Africa, Europe, and Asia prior to the European colonization of the Americas.
The Atlantic slave trade was not the only slave trade from Africa, although it was the largest in volume and intensity. As Elikia M'bokolo wrote in Le Monde diplomatique:
European colonization and slavery in West Africa  Â
Upon discovering new lands through their naval explorations, European colonisers soon began to migrate to and settle in lands outside their native continent. Off the coast of Africa, European migrants, under the directions of the Kingdom of Castile, invaded and colonised the Canary Islands during the 15th century, where they converted much of the land to the production of wine and sugar. Along with this, they also captured native Canary Islanders, the Guanches, to use as slaves both on the Islands and across the Christian Mediterranean.
The Second Atlantic system was the trade of enslaved Africans by mostly English, Portuguese, French and Dutch traders. The main destinations of this phase were the Caribbean colonies and Brazil, as European nations built up economically slave-dependent colonies in the New World.
It is estimated that more than half of the entire slave trade took place during the 18th century, with the British, Portuguese and French being the main carriers of nine out of ten slaves abducted in Africa. By the 1690s, the English were shipping the most slaves from West Africa. They maintained this position during the 18th century, becoming the biggest shippers of slaves across the Atlantic. By the 18th century, Angola had become one of the principal sources of the Atlantic slave trade.
