This suggested an intention to destroy Russia as a political entity, as the Nazis organised the areas adjacent to Greater Germany's eastern provinces in accordance with the geopolitical Lebensraum idea (Drang nach Osten), to benefit future "Aryan" generations. When German forces entered Soviet territory, they immediately implemented this administrative plan instating the Reichskommissariat of "Ostland" in the Baltic lands and "Ukraine" in Ukraine, headed by Hinrich Lohse and Erich Koch respectively. These administrators put in practice the intended measures during the whole of their administrative period, until 1943–44, when the Germans after the Battle of Kursk were gradually driven out by force.
