I believe disease was a key factor if not the primary factor in the depopulation of Native Americans in the Americas. Throughout time, there has always been inequality during the evolution of humanity. Over the course of evolution, different cultures as well as races have progressed more rapidly and at a stronger rate than others have. The depopulation of Native Americans happened because Europeans had better and more efficient supplies as well as immunities to the diseases that they brought over with them.
While the Europeans were traveling to the New World, they often brought domesticated animals with them for sources of food and livestock. When animals and humans are living in close quarters together, it is very likely for exposure to germs to occur. New diseases were brought over by foreigners looking for fame and gold that killed off many of the natives in the new lands. The natives did not stand a chance against these new threats because of a lack of knowledge and supplies to cure themselves. Once the Europeans established diseases as they made land in the New World, their journey had only become easier as their competition were being wiped out from the rapid spread.
Microbes from Europe introduced new diseases and produced devastating epidemics that swept through the native populations (Nichols 2008). The result from the diseases brought over, such as smallpox, was a demographic catastrophe that killed millions of people, weakened existing societies, and greatly aided the Spanish and Portuguese in their rapid and devastating conquest of the existing American empires (Brinkley 2014). Interaction took place with the arrival of whites and foreigners. The first and perhaps most profound result of this exchange was the importation of European diseases to the New World (Brinkley 2014). Natives were exposed to such illnesses as measles, influenza, and typhus. Although, Europeans did have better and more powerful weapons, Native Americans held their own in battle.
In some areas, native populations were virtually wiped out within a few decades of their first contact with whites (Brinkley 2014). Native populations decimated in the southern regions of the Americas because of exposure to infection that they had never seen before. Tribes had been decimated by European plagues not long after the arrival of Columbus (Brinkley 2013). Before the arrival of Europeans, natives had been remarkably healthy and free of any disease. American Indians became much less healthy because of Old World pathogens, and untold numbers died early in the sixteenth century as a result (Thornton 1987).
Furthermore, the European contact with the African continent and the importation of large numbers of slaves from there to this hemisphere brought new diseases to the Europeans in North America (Thornton 1987). Old World diseases easily wiped through a great proportion of American Indians. Once European disease had made contact with ground in the Americas, natives were...
