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.
History of Costa Rica
During the time of conquest, as many as twenty distinct indigenous societies, numbering in the hundreds of thousands and speaking many different languages, inhabited the area The Spanish conquest of Costa Rica lasted more than half a century after it started 1510. The genocidal enslavement of the indigenous societies of Nicoya on the Pacific North coast was the conquest’s first stage. Its second phase began with fruitless attempts to consolidate a Spanish settlement on the country’s Caribbean side. In the process, Spaniards reduced the indigenous population to the point of extinction through disease, war, reprisals, relocation and brutal exploitation. The Native American population stood at about 120,000 in 1569 and had fallen to 10,000 by 1611.
