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.
Indigenous peoples in Colombia
Colombia's indigenous culture evolved from three main groups—the Quimbaya, who inhabited the western slopes of the Cordillera Central; the Chibchas; and the Kalina (Caribs). When the Spanish arrived in 1509, they found a flourishing and heterogeneous Amerindian population that numbered between 1.5 million and 2 million, belonged to several hundred tribes, and largely spoke mutually unintelligible dialects. The two most advanced cultures of Amerindian peoples at the time were the Muisca and Taironas, who belonged to the Chibcha group and were skilled in farming, mining, and metalcraft. The Muisca lived mainly in the present departments of Cundinamarca and Boyacá, where they had fled centuries earlier after raids by the warlike Caribs, some of whom eventually migrated to Caribbean islands near the end of the first millennium A.D. The Taironas, who were divided into two subgroups, lived in the Caribbean lowlands and the highlands of the Sierra Nevada de Santa Marta. The Muisca civilization was well organized into distinct provinces governed by communal land laws and powerful caciques, who reported to one of the two supreme leaders.
