This statement is completely true, the native peoples to the Americas were introduced to diseases such as smallpox which wiped out a majority of the populations. While battles and such took place this was a huge cause of change because of the effectiveness. Positively, however, the natives were also introduced to the trading of European goods such as foods, guns, and livestock, and particularly horses.
They wanted to trap and then trade furs with the Native American groups in that area.
