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.
White Jamaicans
The proportion of white people among the overall population in Jamaica has varied considerably since the establishment of a permanent Spanish settlement in 1509 by Juan de Esquivel. The native Taíno people were virtually extinct by 1600, and the island's population of about 3,000 was then overwhelmingly European. However, over the next century a significant numbers of African slaves were brought to the island. Jamaica became a colony of England in 1655, and a census in 1662 recorded 3,653 whites (87% of the population) and 552 blacks (13% of the population). However, by 1673 there were 7,768 whites (45% of the population) and 9,504 blacks (55% of the population). By the end of the century only about 7,000 out of a total population of 47,000 (or 15%) were white. Most white immigrants were British, many coming voluntarily from other North American colonies or as refugees from colonies like Montserrat and Suriname which were captured by other European powers. There were also thousands of Irish people sent to Jamaica involuntarily in the early years of the colony.
