Istanbul Lig or originally Constantinople Football Association League was founded by James La Fontaine and Henry Pears and started with the 1904-05 season with only four teams as "Istanbul Sunday League". The matches between the four teams, Moda FC, HMS Imogene FC, Elpis FC, and Cadi-Keuy FC were played on Sundays, leading to the name of the Istanbul Sunday League.
