After the Europeans landed on the shore of the Americans, there was a spread of some European diseases which were hitherto unheard of among the Americans. Since the Native Americans have very little immunity against many of these diseases, many of them became victims and not a few lives were lost to these European diseases such as: smallpox, yellow fever, measles and cholera. The effect of these diseases where so severe that at times a whole village could be totally wiped off.
The Europeans on the other hand have developed immunity to these diseases because many of the diseases were from the domesticated animals; and because the Europeans due to their higher level of development social order, had domesticated many of these animal and thereby have high immunity against these diseases.
Difference In Beliefs
The wipe gap in the beliefs of the Native Americans and the Europeans visitors created another avenue of the Europeans to exploit and take advantage of the Americans. The belief about nature among others was one area where there was a huge difference between these two groups. The Americans see nature as something to be admired and cherished as against the belief of the European that nature was just another obstruction. The Europeans became exceedingly greedy and disrespected items such as land that the Native American valued greatly. To add to this, the arrogance displayed by the Europeans made it explicitly clear to the Americans that they cannot co-exist with the Europeans. It is the combination of these factors and some other ones that made the Native Americans vulnerable to the Europeans who came to their land.
