How Crisis Enlarged the Federal Government, 1890–1945

Unit 7 review: key dates, the facts that explain the new federal role from 1898 to 1945, and practice questions.

How Repeated Crises Expanded Federal Power

From the 1890s through World War II, the United States became more industrial, urban, consumer-oriented, globally engaged, and administratively powerful. Overseas expansion, Progressive regulation, wartime mobilization, immigration restriction, mass culture, Depression, New Deal policy, and total war all changed the relationship between citizens, markets, and the federal government. The direction was not uniformly liberal or democratic. Progressives expanded regulation while some embraced segregation, eugenics, and coercive reform. World War I mobilization strengthened federal power while criminalizing dissent. The 1920s expanded consumer opportunity while hardening immigration restriction and nativism. The New Deal enlarged social and economic government while excluding many workers from early protections. World War II fought fascism abroad while Japanese American citizens were excluded and incarcerated at home.
