Slavery began in the British colonies in 1619 when 20 Africans arrived in Jamestown, Virginia. Originally, Africans had similar social status as indentured servants and could gain freedom. However, by the 1660s slavery evolved as a social and economic institution to meet the labor demands of cash crops. Africans were captured in Africa and subjected to the horrific Middle Passage to the Americas, where they were branded and shackled in cramped spaces, resulting in many deaths. Slavery was justified through racism and Africans were deemed better suited than Native Americans for the permanent, cheap labor of plantations. The triangular trade route profited immensely from this exploitation.
