There were a number of factors that contributed to the United States emerging as a world power in the early 1900's.  Industrialism and manufacturing are very important to American international prestige and power. The United States had a vast variety and quantity of natural resources that allowed successful industry to take root in the Northeast.  Due to a relaxed immigration policy, the fulfilling the labor needs of a growing industrial and urban economy was not an issue.  Industrialism created wealth and allowed for the establishment of a technologically sound military instrument. 

The United States was also establishing itself as a world power because of its expansion.  Having reached the West coast through expansion, America looked outside of the continental United States to exert its power and utilize resources of foreign peoples.  The victory in the Spanish-American War, and later in the Philippine-American War allowed the United States to expand into the Pacific and the Caribbean.  This was achieved through a powerful military and a strong desire to use that powerful military.
