The Schieder Commission did not inform readers regarding the implementation of the earlier Lebensraum concept: from 1938/1939 Nazi Germany had expanded its territory far into the east, annexing parts of Czechoslovakia and Poland (Sudetenland, Warthegau). This was intended as only a first step towards establishing the so-called A-A line from Arkhangelsk to Astrakhan (both located in Russia) as Germany's new eastern border. Parts of Poland were "Germanized" by force, the local Polish majority population being subject to mass executions and murder as well as expelled into other parts of Poland.
