Historians have uncovered evidence leading to the estimation that the Nazis’ wartime confiscation of wealth from Europe’s Jews financed about 30 percent of the expenditure of the German armed forces during WWII. The official study of the German Finance Ministry under the Nazis from 1933 to 1945 was conducted by historian Hans-Peter Ullmann. Ullmann, a Cologne history professor, said the German Finance Ministry under the Nazis actively worked to “destroy Jews financially” and to loot wealth in the nations the Germans occupied.
