Descendants of enslaved Africans brought to Charleston in the Middle Passage dance to honor their relatives lost during a remembrance ceremony along the saltwater marsh June 10, 2017 in Sullivan's Island, South Carolina. The Middle Passage refers to the triangular trade in which millions of Africans were shipped to the New World as part of the Atlantic slave trade. An estimated 15 of the Africans died at sea and considerably more in the process of capturing and transporting. The total number of African deaths directly attributable to the Middle Passage voyage is estimated at up to two million African deaths.
