HIAG was a lobby group and a denialist veterans' organisation founded by former high-ranking Waffen-SS personnel in West Germany in 1951. Its main objective was to achieve legal, economic, and historical rehabilitation of the Waffen-SS.

Otto Kumm commanded two Waffen-SS divisions in the latter stages of World War II and was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves and Swords. At the post-war Nuremberg trials, the Waffen-SS – of which Kumm was a senior officer – was declared to be a criminal organisation due to its major involvement in war crimes and crimes against humanity. After the war, Kumm became one of the founders of HIAG, a lobby group and a revisionist organization of former Waffen-SS members.
