FA Red Boys Differdange

Red Boys was founded as SC Differdange in 1907, the year after Luxembourg's first club, Fola Esch, had been set up. Despite the clubs provenance, its first appearance in Luxembourg's league as Red Boys Differdange came only in 1919 (and, then, only in the second division). Soon, though, Red Boys would embark upon the greatest runs of success in Luxembourgish football. During the 1920s and 1930s, Red Boys competed with Spora Luxembourg for dominance of Luxembourgish football. Red Boys was the more successful of the two, and won thirteen trophies in as many years between 1923 and 1936. Despite the staunch competition (Spora won 8 trophies in the same period), this record has never been matched. Despite fading after the Second World War, Red Boys remained one of the largest and most successful teams in Luxembourgish football. Differdange's record was most impressive in the Luxembourg Cup, which the club won more times than any other team (15). In 2003, the club merged with city rivals AS Differdange to become FC Differdange 03.
