Christopher Columbus
Since the late 20th century, historians have criticized Columbus for initiating colonization and for abuse of natives. Among reasons for this criticism is the poor treatment of the native Taíno people of Hispaniola, whose population declined rapidly after contact with the Spanish. Columbus required the natives to pay tribute in gold and cotton. Modern estimates for the pre-Columbian population of Hispaniola are around 250,000–300,000. According to the historian Gonzalo Fernandez de Oviedo y Valdes, by 1548, 56 years after Columbus landed, and 42 years after he died, fewer than 500 Taíno were living on the island. The indigenous population declined rapidly, due primarily to the first pandemic of European endemic diseases, which struck Hispaniola after 1519. The natives had no acquired immunity to these new diseases and suffered high fatalities. There is also documentation that they were overworked.
Catholic Church in Latin America
On December 1511, the Dominican friar Antonio de Montesinos openly rebuked the Spanish authorities governing Hispaniola for their mistreatment of the American natives, telling them "... you are in mortal sin ... for the cruelty and tyranny you use in dealing with these innocent people". King Ferdinand enacted the "Laws of Burgos" and "Valladolid" in response. Enforcement was lax, and while some blame the Church for not doing enough to liberate the Indians, others point to the Church as the only voice raised on behalf of indigenous peoples.
