Racing Fussball Club Union Luxembourg (), usually abbreviated to Racing-Union, is a football club based in Luxembourg City in southern Luxembourg. The etymology of the name originates from Racing Club Luxembourg and Union Sportive Luxembourg, two successful historic clubs of the many that merged to create it. Other clubs that were merged throughout history to form the current club include CA Spora Luxembourg, Sporting Club Luxembourg, CS Alliance 01, FC Aris Bonnevoie, US Hollerich Bonnevoie and Jeunesse Sportive Verlorenkost. History Glorious Early Days Racing Club Luxembourg was founded in 1907 and became the first official Champion of Luxembourg by winning the title in 1909–10. RC Luxembourg also won the first Cup in 1922. Along with Sporting Club Luxembourg and Union Sportive Hollerich, the three clubs of the capital dominated Luxembourgish football in its early days. The supremacy of the capital city's footballers was such that, for the first official match of Luxembourg's national team against France on 29 October 1911, the starting lineup was entirely composed of Racing, Sporting and Union players. The match finished 4–1 in France's favour. First Mergers The domination of the capital city's football clubs drew to a close at the end of the 1920s with the emergence of teams from the south of the country, such as CS Fola Esch and Red Boys Differdange. The decline of sporting success thus led to a phenomenon that was to have a profound impact on the footballing community in the commune, namely the propensity of clubs to engage in mergers. The first big merger occurred in 1923 with the union of the two first Champions of Luxembourg: Racing & Sporting. The origins of Racing were on the Limpertsberg, where they had their pitch on what is today the location of the "Schueberfouer" before moving to the route d'Esch in 1912. It won the first Luxembourg Cup, beating Jeunesse Esch 2–0 in the final. Sporting, the club of the centre of Luxembourg City, had found a pitch on what is today the Winston Churchill Square in 1910 and had also signed off in glory by bringing home the 1919 Championship. In 1923, the two clubs united under the new name of CA Spora Luxembourg. The name "Spora" came from the first three letters of SPOrting and the first two of RAcing. This club would not only become one of the most successful, but also one of the largest sports
