What was hitler's master plan for creating an aryan racial empire?

Hitler wanted the Germans to control over the whole world. He was of the opinion that the German's were the actual descendants of the Aryans. His master plan was to eliminate the Jews, as they were not Aryans and this was his master plan for creating an Aryan racial empire. For Hitler, Jews were the main obstacle for his master plan.

Hitler wanted to extend the Lebensraum of the German nation which he considered to be an Aryan nation of white people of the best quality, while Slavs, Gypsies, and Jews were all inferior for example. He didn't want for any of them to be part of his new empire.
