The 1920s in America saw significant social and cultural changes following World War I. The Republican administrations of Warren G. Harding and Calvin Coolidge promoted business interests and a return to "normalcy." However, the Teapot Dome Scandal tarnished Harding's presidency. Women gained new freedoms in the 1920s as flappers challenged traditional gender norms, but still faced workplace discrimination. Prohibition sparked growth in organized crime as gangsters profited from bootlegging alcohol, despite government failure to enforce the law which was later repealed. Urbanization and the Great Migration of African Americans to northern cities also transformed American society in the 1920s.
