The Detroit Lions won the National Football League championship in 1935. The Detroit Tigers won the American League pennant in 1934 and again in 1935, subsequently winning the World Series in 1935. The Detroit Red Wings won the National Hockey League's Stanley Cup in 1936 and 1937. This meant Detroit featured the defending champions in the NFL, NHL and MLB simultaneously from April 11, 1936 through October 5, 1936. Detroit remains the only city to win three major professional sports championships in the same year and the only city to win NHL and NFL titles in the same year (a feat it repeated in 1952).
