December 22, 1915
The Federal League, an upstart third major league, is dissolved. The league began play in 1913 and was considered a "major league" in 1914 and 1915. Eight teams made up the Federal League in 1914-15, with franchises located in Baltimore, Brooklyn, Buffalo, Chicago, Indianapolis (1914), Kansas City, Newark (1915) Pittsburgh, and St. Louis.
The Chicago team didn't have a nickname in 1914 - they were the Chicago Federals. In 1915, they won the league championship as the Chicago Whales. The Whales played at Weeghman Park, named for owner Charles Weeghman. When the Federal League folded, Weeghman and a group of investors including William Wrigley Jr. went together to buy the National League's Cubs. The Cubs moved to Weeghman Park in 1916, which continues as the Federal League's living legacy, Wrigley Field. (Photos - Wikimedia, listed as public domain.)
