The document summarizes the conquest and settlement of the western United States and Canada. It describes how the U.S. Cavalry fought Native American tribes to secure land for white settlers through treaties that reduced tribal lands and movement. In contrast, the Canadian government was more reluctant to intervene in western affairs and did so mostly due to fears of U.S. takeover rather than Native uprisings. Western towns in both nations came to have a similar gridded layout that was practical for land speculators and displaced semi-nomadic Native peoples.
