The 1920s in America saw a period of social and economic change following World War I. Republicans dominated politics under Presidents Harding and Coolidge, pursuing pro-business policies like tax cuts and deregulation. This led to rapid economic growth and widespread consumerism as new industries like automobiles flourished. However, corruption scandals tainted Harding's administration. Socially, immigration restrictions increased due to nativism, while the Ku Klux Klan saw a resurgence targeting Catholics, Jews and immigrants. Overall the decade was marked by economic prosperity, mass consumerism, and social tensions.
