The European colonization of America forever changed the lives and cultures of the Native Americans. The huge number of European settlers brought not only some helpful tools to the New World, but also carried new germs.
In the 15th century, Spaniards and other Europeans brought horses to America. Some of these animals escaped and began to breed and increase their numbers in the wild. Ironicallly, the horse had originally evolved in America, but the last American horses were game for early hunters and went extinct about 9000 years ago, just after the end of the last ice age. The re-introduction of the horse had a profound impact on Native American culture in the Treat Plains of North America. This new mode of travel made it possible for some tribes to greatly expand their territories, exchange goods with neighboring tribes, and more easily capture game.
Europeans also brought diseaes against which the Native Americans had no immunity. Chicken pox and measles, though common and rarely fatal among Europeans, often proved lethal to Native Americans, and more dangerous diseases such as smallpox were especially deadly. It is difficult to estimate the total percentage of the Native American population killed by these diseases. Epidemics often immediately followed European exploration, sometimes destroying entire villages. Some historians believe that up to 80 percent of some Native populations may have died due to European diseases.
