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.
Within only two years, 125,000 (half of the population) of the original natives on the island were dead. If I were a Native American, I would mark October 12, 1492, as a black day on my calendar. Shockingly, Columbus supervised the selling of native girls into sexual slavery. Young girls of the ages 9 to 10 were the most desired by his men. In 1500, Columbus casually wrote about it in his log.
