The document summarizes the triangular slave trade route between Europe, Africa, and the Americas. Raw materials from the colonies were traded for slaves in Africa, who were then transported in inhumane conditions on the Middle Passage to the colonies, where they were sold and the ships were loaded with goods like sugar, tobacco, and rum to complete the triangle by returning to Europe. Over 1.5 million Africans died during the grueling Middle Passage voyages due to disease, malnutrition, and cruelty from captains and crews.
