The Militant League for German Culture (German: Kampfbund für deutsche Kultur, KfdK), was a nationalistic anti-Semitic political society during the Weimar Republic and the Nazi era. It was founded in 1928 as the Nationalsozialistische Gesellschaft für deutsche Kultur (NGDK, National Socialist Society for German Culture) by Nazi ideologue Alfred Rosenberg and remained under his leadership until it was reorganized and renamed to the National Socialist Culture Community (Nationalsozialistische Kulturgemeinde) in 1934.
Its aim was to make a significant imprint on cultural life in Germany that was based on the aims and objectives of the inner circles of the Nazi Party. Upon its reorganization, it was merged with the Deutsche Bühne (German Stage), connected with the establishment of the official body for cultural surveillance, the "Dienstelle Rosenberg" (DRbg, Rosenberg Department), which was later known as the Amt Rosenberg (ARo, Rosenberg Office).
