The U.S. government’s policies towards Native Americans in the second half of the nineteenth century were influenced by the desire to expand westward into territories occupied by these Native American tribes. By the 1850s nearly all Native American tribes, roughly 360,000 in number, lived to the west of the Mississippi River. These American Indians, some from the Northwestern and Southeastern territories, were confined to Indian Territory located in present day Oklahoma, while the Kiowa and Comanche Native American tribes shared the land of the Southern Plains.
It took 60 years as the westward expansion took place from 1801-1861.
American imperialism refers to the policy of extending the control of the United States over areas that do not belong to its territory. This can sometimes include military action, diplomacy or economic intervention.
There are some arguments for imperialism. Some people argue that imperialism can bring political stability and economic success to countries that are under the control of the United States. As the U. S. is one of the most developed countries in the world, it can also bring development to controlled countries.
The arguments against imperialism usually focus on the right of self-determination. People who suscribe to this view argue that all people deserve to have control over their political life, and to be free of foreign intervention. Many also argue that imperialism is a selfish doctrine that often benefits the colonizer while damaging the native population.
