Foreign Affairs from Imperialism to Post-World War I (1898-1930)

The industrial and territorial growth of the United States fostered expansion overseas. Greater involvement in the world set the stage for American participation in World War I and attempts to preserve post-war peace.

Content Statement

15. As a result of overseas expansion, the Spanish-American War and World War I, the United States emerged as a world power.

Content Elaborations

With the closing of the western frontier, Americans developed favorable attitudes toward foreign expansion. Pushed along by global competition for markets and prestige, an expanded navy and a sense of cultural superiority, the United States engaged in a series of overseas actions which fostered its move to global power status. The annexation of Hawaii followed by a successful conclusion to the Spanish-American War allowed the United States to join other nations in imperialist ventures.

With its entry into World War I, the United States mobilized a large army and navy to help the Allies achieve victory. After the war, European countries were forced to concentrate their resources on rebuilding their countries. However, the United States enjoyed a brief period of economic prosperity and was able to exert authority as a world power.
