The United States and World War I
- Ross A. KennedyRoss A. KennedyDepartment of History, Illinois State University
World War I profoundly affected the United States. It led to an expansion of America’s permanent military establishment, a foreign policy focused on reforming world politics, and American preeminence in international finance. In domestic affairs, America’s involvement in the war exacerbated class, racial, and ethnic conflict. It also heightened both the ethos of voluntarism in progressive ideology and the progressive desire to step up state intervention in the economy and society. These dual impulses had a coercive thrust that sometimes advanced progressive goals of a more equal, democratic society and sometimes repressed any perceived threat to a unified war effort. Ultimately the combination of progressive and repressive coercion undermined support for the Democratic Party, shifting the nation’s politics in a conservative direction as it entered the 1920s.
