Despite the extreme nationalism of Naumann and his colleagues, the Nazi regime did not accept the Association of German National Jews as a legitimate intermediary. Following the passage of the Nuremberg Laws, the VnJ was declared illegal and dissolved on 18 November 1935. Naumann was arrested by the Gestapo the same day, and imprisoned at the Columbia concentration camp. He was released after a few weeks, and died of cancer in May 1939. Most other members and their families were murdered in the Holocaust.
Always worth a read whenever I see these stories.
