USA HISTORY

Detailed explanation-1: -Native American populations declined between 1492 and 1900 CE, instigated by the European colonization of the Americas. However, the magnitude, tempo, and ecological effects of this depopulation remain the source of enduring debates.

Detailed explanation-2: -Settlers killed off huge numbers of people in conflicts and also by spreading disease, which reduced the indigenous population by 90% in the century following Christopher Columbus’s initial journey to the Americas and Caribbean in 1492.

Detailed explanation-3: -American Indian populations plummeted after the arrival of Europeans in the New World, largely because of the spread of smallpox, typhus, measles, and other infectious diseases.

Detailed explanation-4: -Most scholars agree that diseases introduced from the Eastern Hemisphere, including smallpox, measles, and influenza, were the overwhelming cause of population decline (Cook, 1998). The relationship between epidemic disease and American Indian population decline is relatively well documented in the nineteenth century.

Detailed explanation-5: -Diseases like smallpox, measles, typhus, and cholera quickly spread and depleted Native American populations. The disease spread quickly because Native Americans were not immune to these diseases. As a result, up to 95% of the indigenous population in the Americas died.
