The franchise that became the Bears was founded by businessman A.E. Staley in 1920 and was first known as the Decatur (Illinois) Staleys. George Halas became player-coach of the new team, which he relocated to Chicago in 1921 after Staley handed the young franchise over to him. (Halas, affectionately known as “Papa Bear,” prowled the sidelines as head coach until 1968.) The team won the American Professional Football Association (APFA) championship in its first season in Chicago, and it was renamed the Bears in 1922, the same year the APFA became the NFL. The early Chicago teams established a rivalry with the Green Bay Packers, which became one of the sport’s most storied feuds. Led by a dominant rushing attack that featured future Hall of Fame backs Red Grange and Bronko Nagurski, the Bears captured NFL championships in 1932 and 1933, the former of which was won in the first play-off game in league history, a 9–0 victory over the Portsmouth (Ohio) Spartans.
