Calvin Coolidge's tenure as the 30th president of the United States began on August 2, 1923, when Coolidge became president upon Warren G. Harding's death, and ended on March 4, 1929. A Republican from Massachusetts, Coolidge had been vice president for 2 years, 151 days when he succeeded to the presidency upon the sudden death of Harding. Elected to a full four–year term in 1924, Coolidge gained a reputation as a small-government conservative. Coolidge was succeeded by former Secretary of Commerce Herbert Hoover after the 1928 presidential election.
