After the liberation, Germany was provisionally ruled by military governments that were officially subordinate to the Allied Control Council, which was established in the summer of 1945. The American, British, French and Soviet occupation zones each had their own military governor. On the American side, the Military Government of Germany – known from October 1945 as the Office of Military Government for Germany, U.S. (OMGUS) – was supposed to dissolve Nazi organizations, appoint unincriminated Germans to political office and pass new legislation during a transitional phase. The occupying officers in the different parts of the US occupation zone were also responsible for denazification. This meant that Germans who had previously held positions in Nazi organizations were supposed to be barred from administration, politics, culture and business. To this end, the Military Government questioned the German civilian population using questionnaires that were more detailed than those for the liberated concentration camp prisoners.
