European Colonization of The Americas - Disease and Indigenous Population Loss

Disease and Indigenous Population Loss

The European and Asian lifestyle included a long history of sharing close quarters with domesticated animals such as cows, pigs, sheep, goats, horses, and various domesticated fowl, which had resulted in epidemic diseases unknown in the Americas. Thus the large-scale contact with Europeans after 1492 introduced novel germs to the indigenous people of the Americas. Epidemics of smallpox (1518, 1521, 1525, 1558, 1589), typhus (1546), influenza (1558), diphtheria (1614) and measles (1618) swept ahead of initial European contact, killing between 10 million and 20 million people, up to 95% of the indigenous population of the Americas. The cultural and political instability attending these losses appears to have been of substantial aid in the efforts of various colonists to seize the great wealth in land and resources of which indigenous societies had customarily made use.

Such diseases yielded human mortality of an unquestionably enormous gravity and scale – and this has profoundly confused efforts to determine its full extent with any true precision. Estimates of the pre-Columbian population of the Americas vary tremendously.

Others have argued that significant variations in population size over pre-Columbian history are reason to view higher-end estimates with caution. Such estimates may reflect historical population maxima, while indigenous populations may have been at a level somewhat below these maxima or in a moment of decline in the period just prior to contact with Europeans. Indigenous populations hit their ultimate lows in most areas of the Americas in the early twentieth century; in a number of cases, growth has returned.
