Calvin Coolidge, a Republican, served as the 30th president of the United States from August 2, 1923, to March 4, 1929 after succeeding Warren G. Harding. He was known for his quiet demeanor, frugality, and advocacy of limited government and pro‑business policies.
Coolidge presided over much of the Roaring Twenties, a period of economic growth; his administration pursued tax cuts, reduced federal spending, and favored business-friendly policies that many credit with sustaining short-term prosperity.
Historians debate his legacy: supporters praise his integrity, fiscal restraint, and restoration of public trust after earlier scandals, while critics argue his laissez-faire approach and limited regulation contributed to conditions that preceded the Great Depression. He also signed the Indian Citizenship Act (1924), supported the Dawes Plan for European reparations, and approved the Kellogg–Briand Pact.
