Hitler decreed the creation of the Nazi Party organization "Arbeitsbereich Osten der NSDAP" for the new eastern occupied territories on April 1, 1942. This move had been bitterly resisted by both Rosenberg, who rightly feared that the transformation of the administration of the eastern territories from a state to a party bureaucracy would spell the effective end of the authority of his ministry (which was a state organ), and Heinrich Himmler, who rightly feared that an arbeitsbereich's establishment would be accompanied by the commissars becoming RVKs (commissars for war) and thus enormously empowered at the expense of the SS, which had already been steadily losing ground since late September the previous year, when the commissariat government began establishing itself with local commissars asserting control over the police in their territories, hitherto controlled by the SS. Himmler and Rosenberg's rearguard resistance soon collapsed in the face of pressure from Martin Bormann in Berlin, and Koch and Lohse in the field. Rosenberg at least managed to be appointed Reichsleiter ("Reich leader") of the new arbeitsbereich. Rosenberg later attempted to take such political power into the political section of the ministry to keep all party issues in his control, and prohibited the creation of organizations and any political activity in the East without his express authorization. Needless to say, he was entirely disobeyed.
