As the campaign against the Soviet Union advanced eastward, the occupied territories would gradually be transferred from military to civilian administration. Hitler's final decision on its administration entailed the new eastern territories being divided into four "Reichskommissariats" in order to destroy Russia as a geographical entity by dividing it into as many different parts as possible. These new institutions were to be under the nominal supervision of Reichsleiter Alfred Rosenberg as head of the Reich Ministry for the Occupied Eastern Territories. The leaders of these provinces, the Reichskommissars, would however be direct subordinates of Hitler himself, and answerable only to him. Conquered territories of most of Russia proper were initially to become a "Reichskommissariat Russland" (Reich Commissariat of Russia) according to Rosenberg's plans, although this was later changed to "Moskowien" (Muscovy) informally also known as "Moskau" (Moscow). These eastern districts were thought to be the most sensitive to administer of the conquered territories. As a consequence, they would be managed from the regional capitals and directly by the German government in Berlin.
