Explanation:

The Atlantic slave trade, transatlantic slave trade, or Euro-American slave trade involved the transportation by slave traders of various 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.[1] The majority of those who were enslaved and transported in the transatlantic slave trade were people from Central and West Africa that had been sold by other West Africans to Western European slave traders,[2][3] while others had been captured directly by the slave traders in coastal raids;[4] Europeans gathered and imprisoned the enslaved at forts on the African coast and then brought them to the Americas.[5][6
