The document summarizes the triangular trade route that developed between Europe, Africa, and the Americas in the 16th-18th centuries. It describes how the demand for slaves in European colonies led to the establishment of the slave trade, with goods being shipped from Europe to Africa, enslaved people from Africa to the Americas, and raw materials from the Americas back to Europe. The slave trade was driven by the growth of sugar plantations in Brazil and the Caribbean, which required large amounts of forced labor and led to millions of Africans being captured and sold into the system of slavery.
