The National Football League was formed on August 20, 1920, as the American Professional Football Conference. The league changed its name to the American Professional Football Association (APFA) on September 17, 1920, and changed its name to the National Football League on June 24, 1922, after spending the 1920 and 1921 seasons as the APFA.
