The presidency of Warren G. Harding began on March 4, 1921, when Warren G. Harding was inaugurated as President of the United States, and ended when he died on August 2, 1923, a span of 881 days. He also signed into law several bills designed to address the farm crisis and, along with Secretary of Commerce Herbert Hoover, promoted new technologies like the radio and aviation. Daugherty's strategy focused on making Harding liked by or at least acceptable to all wings of the party, so that Harding could emerge as a compromise candidate in the likely event of a convention deadlock. In the first two decades of the 20th century, immigration to the United States had increased, with many of the immigrants coming from Southern Europe and Eastern Europe rather than Western Europe.
