The indigenous populations of the Americas sharply plummeted following the arrival of Europeans from 1492 onward. Not all the mortality was consciously inflicted: disease, hardship, and the severing of social ties all took their toll, although diseases were also sometimes introduced for the purpose, amounting to biological warfare. The native tribes of the Caribbean were eliminated like the Guanches in the Canary Islands the previous century (Crosby 1986). Central Mexico, with an estimated pre-Conquest population of 25 million, was reduced to a residual population of a million in the 17th century. In 1790, when the first U.S. census was executed, there were 300 Native Americans left in Pennsylvania, 1500 each in New York and Massachusetts, and still some 10,000 in the Carolinas (Braudel 1984 p 393). See cultural genocide.
The population reduction, sometimes by government policy and sometimes not, of the Natives of South and North America by Europeans is estimated to be one of the largest and longest in history.[5]
Various estimates of the pre-contact Native population of the continental U.S. and Canada range from 1.8 to over 12 million. Over the next four centuries, their numbers were reduced to a low of 237,000 by 1900. It has been estimated that the Native population of what is now Mexico was reduced from 30 million to only 3 million over the first four decades of Spanish rule.
European persecution of Natives started with Christopher Columbus’ arrival in San Salvador Island in 1492. Native population dropped dramatically over the next few decades. Some were directly exterminated by Europeans. Others died indirectly as a result of contact with introduced diseases for which they had no resistance.
Over the next four centuries, European settlers would systematically displace Native American peoples, from the Arctic to South America. This was accomplished through varying combinations of warfare, the signing of treaties (of which the Natives may not have fully understood the consequences at times), forced relocations to barren lands, destruction of their main food supply — such as the bison (also the central element of many native religions) — and the spread of European disease, notably smallpox.
