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.
Haiti
At the time of European conquest, the island of Hispaniola, of which Haiti occupies the western three-eighths, was one of many Caribbean islands inhabited by the Taíno Native Americans, speakers of an Arawakan language called Taino, which has been preserved in the Haitian Creole language. The Taíno name for the entire island was "Haiti". The people had migrated over centuries into the Caribbean islands from South America. Genetic studies show they were related to the Yanomami of the Amazon Basin. They also originated in Central and South America. After migrating to Caribbean islands, in the 15th century, the Taíno were pushed into the northeast Caribbean islands by the Caribs.
