American Imperialism

 

                 American imperialism is a term referring to the economic, military, and cultural influence of the United States on other countries. The concept of an American Empire was first popularized during the presidency of James K. Polk who led the United States into the Mexican–American War of 1846, and the eventual annexation of California and other western territories via the Treaty of Guadalupe Hidalgo and the Gadsden purchase. The imperial behavior for the United States dates at least to the Louisiana Purchase, which he describes as an "imperial acquisition – imperial in the sense of the aggressive encroachment of one people upon the territory of another, resulting in the subjugation of that people to alien rule." The U.S. policies towards the Native Americans he said were "designed to remold them into a people more appropriately conformed to imperial desires".
^{The United states was seen as the ultimate powerful country of all, and in a way it was for the reason that it had the strongest military and navy and they had the money to attack when being attacked.}
