We are talking about the Spanish priest Antonio de Montesinos (1475-1540). He was a Dominican friar who had been sent to Hispaniola Island, modern-day Dominican Republic, and realized the way native Indians had been treated. So what he did next was to denounce the horrible ways in which Europeans treated the Indians.
