AP US History
America as a World Power refers to the United States' emergence and establishment as a dominant global influence in political, economic, and military affairs, particularly during the late 19th and early 20th centuries. This period marked a shift from isolationism to active involvement in international relations, characterized by imperialistic endeavors, participation in major conflicts, and efforts to shape global policy. The U.S. sought to expand its influence through both soft power and military intervention, fundamentally altering its role on the world stage.
