Why did the Chicago Bears move to Chicago?

Answer 1

Why? Money shortage in 1920 because of a recession forced them to move from Decatur, IL:

George Halas was hired in 1920 by A. E. Staley of the Staley Manufacturing Co. (whose primary product was cornstarch) to form both a football and a Baseball team for the company. In order to find opponents, Halas pushed the football team into the new league that was being formed, the American Professional Football Association. A severe recession in early 1921 forced Staley to lay off the athletes he had hired; he suggested to Halas that the football team should move to Chicago, and said he would provide $5000 to assist in the move if the club would keep the name "Staleys" for one season. Thus, in 1921, Halas's men were called the Chicago Staleys when they became the first official league champion.
