Think back to the question you considered at the beginning of the lesson. based on what you learned, do you think the united states was justified in its decision to go to war with plains tribes?
justifications for going to war:
to acquire new territory
to try to improve the lives of people in another country
to defeat a potential enemy who may be planning to attack
to defend against an invading enemy

The correct answer is A) to acquire new territory.

The United States' justification to go to war with Plains tribes was to gain more territory.

Under the idea of Manifested Destiny, President Jefferson allowed the occupation of the new territories of the West. The Clark and Lewis expedition had shown that the territory was vast and in need of occupation by white settlers to make the land productive. So conflicts were permanent between Native American Indian tribes and white settlers since the colonial times. Things got worse with decisions such as the Dewes Act of 1887, that ended the reservation system. Among the Plain tribes affected were the Kiowa, Comanche, and Cheyenne.
