The Middle Passage was the leg of the Atlantic slave trade that transported slaves from Africa to North America, South America, and the Caribbean. It was called the Middle Passage as the slave trade was a form of Triangular trade; boats left Europe, went to Africa, then to America, and then returned to Europe.

Slave traders acquired slaves from numerous ports in Africa. They were able to pack nearly 300 slaves and approximately 35 crew into most slave ships. The men were normally chained together in pairs to save space — right leg to the next man's left leg — while the women and children may have had somewhat more room. The captives were fed very small portions of corn, yams, rice, and palm oil, normally just enough to sustain them. Sometimes captives were allowed to move around during the day, but many ships kept the shackles on throughout the journey.

It is estimated that 15% of the captured slaves died on the journey.
