Deutsch-Vlämische Arbeitsgemeinschaft ("German-Flemish Working Group"), better known as DeVlag, was a pro-Nazi organization active in Flanders during the German occupation of Belgium. It was founded in 1936 by academics Jef Van de Wiele and Rolf Wilkening as a cultural association, with the purpose of strengthening the exchange of students and professors between the universities of Leuven and Cologne.
Its membership reached hundreds by the late 1930s. In May 1941, after the German invasion, DeVlag started receiving financial backing from the SS, and was reorganized into a National Socialist organization. This was first done in secrecy. German SS-Obergruppenführer Gottlob Berger was later appointed as DeVlag's president, and the bond between the two organizations was thus made official.
DeVlag's orientation towards the SS brought it into a dispute with the Flemish National Union (VNV), the main collaborative organization in occupied Flanders, which originally had supported the "cultural" activities of DeVlag. The VNV was a Flemish nationalist movement, which envisioned an independent Flanders, or perhaps Dietsland, in a German-dominated Europe, while Van de Wiele considered Dutch merely a German dialect and the Flemish people a part of the German race. DeVlag saw Dutch or Flemish nationalism as provincialism, and supported the outright annexation of Flanders into the Greater German Reich. The VNV also had partly clerical roots, while the SS ideology endorsed by DeVlag held anti-Christian notions. While DeVlag was supported by the SS, the VNV received support from the Wehrmacht military occupation (Militärverwaltung) and from the head of the military government, Alexander von Falkenhausen.
Both groups competed to recruit members to the Waffen-SS. In 1943, when the VNV started its youth wing De Nationaal-Socialistische Jeugd in Vlaanderen ("National-Socialist Youth in Flanders"), DeVlag responded by setting up the Flemish wing of the Hitler Youth.
DeVlag reached the peak of 50.000 members in 1943. In late 1944, the Nazi leadership answered the demands of DeVlag by annexing Flanders and Wallonia into the German Reich, but this was more theoretical than actual, as Belgium was soon liberated by the advancing Allied forces. Van de Wiele was, however, given the title "National Leader of the Flemish people" (Landsleider van het Vlaamsche volk) and DeVlag was deemed by the Germans as the sole party representing the national socialist unity in Flanders.
