An Allied Control Council was established on 30 August 1945 to execute supreme governmental power over Allied-occupied Germany , which now did not include the German eastern territories . In its initial proceedings , the Allied Control Council assumed itself to be the sole repository of German state sovereignty especially in respect of external relations , but largely left each of the Allied Powers to administer their own occupation zones as they saw fit . The functioning of the Allied Control Council proved however , to be severely compromised by obstruction from one or another of the Allied Powers represented on it ; initially France ( who had not been invited to the Potsdam Conference and refused to be bound by the Potsdam Agreement ) , and latterly by the Soviet Union - who in 1948 walked out of the Control Council , preventing it from meeting again until 1991
