Middle Passage

The Middle Passage was the stage of the triangular trade in which millions of people from Africa were shipped to the New World, as part of the Atlantic slave trade. Ships departed Europe for African markets with manufactured goods, which were traded for purchased or kidnapped Africans, who were transported across the Atlantic as slaves; the slaves were then sold or traded for raw materials, which would be transported back to Europe to complete the voyage. Voyages on the Middle Passage were a large financial undertaking, and they were generally organized by companies or groups of investors rather than individuals.

Traders from the Americas and Caribbean received the enslaved Africans. European powers such as Portugal, England, Spain, France, the Netherlands, Denmark, Sweden, and Brandenburg, as well as traders from Brazil and North America, took part in this trade. The enslaved Africans came mostly from eight regions: Senegambia, Upper Guinea, Windward Coast, Gold Coast, Bight of Benin, Bight of Biafra, West Central Africa and Southeastern Africa.

An estimated 15% of the Africans died at sea, with mortality rates considerably higher in Africa itself in the process of capturing and transporting indigenous peoples to the ships. The total number of African deaths directly attributable to the Middle Passage voyage is estimated at up to two million; a broader look at African deaths directly attributable to the institution of slavery from 1500 to 1900 suggests up to four million African deaths.

For two hundred years, 1440–1640, Portuguese slavers had a near monopoly on the export of slaves from Africa. During the eighteenth century, when the slave trade transported about 6 million Africans, British slavers carried almost 2.5 million.
