Istanbul Football League

The Istanbul Football League (İstanbul Futbol Ligi) was founded as a regional football league under the name Constantinople Football Association League by James La Fontaine and Henry Pears in Istanbul, the capital of the former Ottoman Empire, in 1904. The Istanbul League was the first football organization ever in the Ottoman Empire and later Turkey. In the inaugural 1904–05 season the matches between the four teams, Moda FC, HMS Imogene, Elpis FC, and Cadi-Keuy FC were played on Sundays, leading to the name of the league, Istanbul Sunday League. Henry Pears, an Englishman and one of the three founders, promised to ultimately award the shield to the club with the most championships won during the initial 10 years. The Istanbul Friday League was founded in 1915 and replaced the Istanbul Sunday League. Seven teams participated in its inaugural 1915–16 season. From 1923–24 to 1950–51 the league was called Istanbul League. The name was later changed and became Istanbul Professional League in the 1952 season, as professionalism was introduced by the Turkish Football Federation in 1951.

Fenerbahçe are the most successful club, having won the league a record 16 times in total.
