For the first seventeen years of existence, Spora would battle with FA Red Boys Differdange for ultimate ascendancy in Luxembourgish football.

Although Red Boys won more trophies in this period, Spora picked up almost every piece of silverware that Red Boys didn't, with seven league titles and three Luxembourg Cups in just fifteen years.

After the Second World War, Spora continued to win titles (albeit less frequently than before).

To its pre-war haul, the club added four more championships and won the Luxembourg Cup another five times.

In 1956, Spora recorded one of the most celebrated European club results in Luxembourgish history, as it beat the West German champions, Borussia Dortmund.
