美國經濟大蕭條  (1865年十一月2日～1923年八月2日)

開端 終結 在位 1921年 1923年 

　　沃倫·蓋瑪利爾·哈定（Warren Gamaliel Harding，1865年11月2日－1923年8月2日） 共和黨籍美國總統(1921年3月4日 – 1923年8月2日)，任內因為錯誤的任命導致腐敗，為此在歷史上多受非議。他由於突發心髒病於1923年8月2日去世。他的副總統，卡爾文·柯立芝於當日繼任了總統。

　　Warren Gamaliel Harding (November 2, 1865 – August 2, 1923) was the 29th President of the United States, serving from 1921 until his death from a heart attack or stroke in 1923. A Republican from Ohio, Harding was an influential newspaper publisher. He served in the Ohio Senate (1899–1903) and later as Lieutenant Governor of Ohio (1903–1905) and as a U.S. Senator (1915–1921).
　　
　　His conservative stance on issues such as taxes, affable manner, and campaign manager Harry Daugherty's 'make no enemies' strategy enabled Harding to become the compromise choice at the 1920 Republican National Convention. During his presidential campaign, in the aftermath of World War I, he promised a return to "normalcy". In the 1920 election, he and his running-mate, Calvin Coolidge, defeated Democrat and fellow Ohioan James M. Cox, in the largest presidential popular vote landslide in American history since the popular vote tally began to be recorded in 1824: 60.36% to 34.19%.
　　
　　Harding headed a cabinet of notable men such as Charles Evans Hughes, Andrew Mellon, future president Herbert Hoover and Secretary of the Interior Albert B. Fall, who was jailed for his involvement in the Teapot Dome scandal. In foreign affairs, Harding signed peace treaties that built on the Treaty of Versailles (which formally ended World War I). He also led the way to world Naval disarmament at the Washington Naval Conference of 1921–22.
