The team was founded in 1912 as a merger between Minerva Dudelange and Jeunesse de la Frontière 1908 Dudelange. Under German occupation in World War II, its name was changed between 1941 and 1944 to SV Düdelingen as part of the Germanisation program.[1]
The team was strongest in the late 1930s and 1940s. They won the Luxembourg Cup in 1939 and came runners-up in the Luxembourg National Division four times, reaching another cup final in 1958.[2][3]
