Spanish: Enslaved Africans in Mexico, 1537 (PDF) Europeans' enslavement of Native Americans began with Columbus. As the governor of Hispaniola, he forced the Taino Indians to labor in the Spanish fields and mines, and he brought Taino slaves to Spain on his return journeys.
Columbus spearheaded the transatlantic slave trade and has been accused by several historians of initiating the genocide of the Hispaniola natives. Columbus himself saw his accomplishments primarily in the light of spreading the Christian religion. Never admitting that he had reached a continent previously unknown to Europeans rather than the East Indies he had set out for, Columbus called the inhabitants of the lands he visited indios (Spanish for Indians).
