The Middle Passage was the transporting of captured Africans to the Americas in the New World, where they would be sold into slavery.

The Middle Passage was one of the stages of the triangular trade, which contained three legs in its entirety. The first stage was the transporting of manufactured goods from Europe to Africa. These could be things like clothes, food, weapons, or other items. The second stage was the Middle Passage, as I stated above, it was the transporting of captured Africans to the Americas. The third and final stage was the transporting of materials from the colonies to Europe. These were things like indigo, cotton, sugar, rice, tobacco, or other materials.

The second stage, the Middle Passage, is known today for being terrible. The captives were forced onto ships with huge numbers, which made crowding inevitable. They had little space to move, which caused many people to get diseases and ultimately die. They often were given spoiled food and were beaten by the white men on the ship. When they reached the Americas they would then be sold into slavery.
