Chapter -3 Nazism and the Rise of Hitler The Nazi World Wide According to Nazi ideology, there was no equality between people, but only racial hierarchy. The Nazis quickly began to implement their dream of creating an exclusive racial community of pure Germans by physically eliminating all those who were considered undesirable.

The other aspect of Hitler’s ideology related to the geopolitical concept of Lebensraum, or living space. Jews were the worst sufferers in Nazi Germany. Hitler believed in pseudoscientific theories of a race which said that conversion was no solution to the Jewish problem. It had to be solved through their total elimination.
