This document provides a brief history of Negro slavery, outlining its origins and spread. It began in 1442 when Portuguese explorer Prince Henry had African prisoners exchanged for 10 African slaves. It then spread to Spanish colonies in the early 1500s as native Indians died out and African slaves were imported. Englishman Sir John Hawkins was the first to engage in the slave trade, transporting 300 Africans to Hispaniola against their will in the 1560s. Over the following centuries, slavery took hold in British, French and other colonies in the Americas. The document argues slavery has had disastrous effects on Africa by fueling warfare, private kidnapping, and leaders' sale of their own people for goods from European ships. It
