In Nazi propaganda the slogan was repeatedly used to at least justify or legitimize the German conquest of Poland and the Soviet Union and for the massive territorial expansion into Eastern Europe to ensure Germanic Aryan Herrenvolk ("Aryan master race") rule over Poles and Russians who the Nazis considered "non Aryan" and subhuman. Slavs as non-Aryans were to be ethnically cleansed and exterminated, and their territories settled by Germans. From the very early days of the Nazi party, the notion that the Germans were people without living space and had a right to expand was widespread among German nationalists and right-wing organisations.
