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.
Hispania
The Iberian peninsula has long been inhabited, first by early hominids such as "Homo erectus", "Homo heidelbergensis" and "Homo antecessor". In the Paleolithic period, the Neanderthals entered Iberia and eventually took refuge from the advancing migrations of modern humans. In the 40th millennium BC, during the Upper Paleolithic and the last ice age, the first large settlement of Europe by modern humans occurred. These were nomadic hunter-gatherers originating on the steppes of Central Asia. When the last Ice Age reached its maximum extent, during the 30th millennium BC, these modern humans took refuge in Southern Europe, namely in Iberia, after retreating through Southern France. In the millennia that followed, the Neanderthals became extinct and local modern human cultures thrived, producing pre-historic art such as that found in L'Arbreda Cave and in the Côa Valley.
