Club sportif des Terreaux was founded in 1911 by a group of young people who love sports, most of whom were currently mobilized.
[1] CS Terreaux quickly established itself in the region's sporting circles, and in 1912, the club won a third-series football championship for teams with one or two years of existence, mainly thanks to the camaraderie that united all of its members.
[1] In the following year, in 1913, the club won the second-series after defeating AFC de Saint-Étienne in a promotion match, thus becoming one of the six first-series teams of the Lyon committee.
In order to give some activity back to these football clubs, the USFSA created the Coupe des Alliés (1915–18), and CS Terreaux reached the final of the 1915–16 edition, after defeating the likes of AS Lyonnaise (3–1), FC Lyon (4–2), Olympique de Marseille (4–2), and International FC Nice (2–1).
[7] In the 1919 USFSA Football Championship, the last of its kind, CS Terreaux reached the semifinals, where they once again faced Olympique de Marseille, and once again lost, this time by a score of 6–1.
