"Some scholars consider the initial period of the Spanish conquest—from Columbus’s irst landing in the Bahamas until the middle of the sixteenth century— as marking the most egregious case of genocide in the history of mankind. The death toll may have reached some 70 million indigenous people (out of 80 million) in this period. Millions of natives died of disease— smallpox, measles, influenza, and typhus, in particular— brought to the Americas by the conquest. Alien microbes traveled more quickly than did the European conquerors themselves, by the highest estimates killing an estimated 95 percent of the pre-Columbian Native American population, by the lowest estimates about a half. There is no evidence that the Spanish purposely infected the indigenous peoples. Yet the Spanish imposed conditions upon the Indians that made them more susceptible to the imported diseases. They were exploited as forced laborers and were concentrated in work camps, especially as the search for gold and silver brought a frenetic Spanish interest in mining for precious ores. The Indians were forcibly deported from their homes to alien locations for the purpose of replacing local labor of natives who had died out. The newcomers were deprived of food and water and housed, if at all, in unsanitary, makeshift dwellings. They were separated from their families and normal support systems. They were beaten, brutalized, and deprived of freedom."
