Answer: According to Mein Kampf, Adolf Hitler's reasoning for incorporating Austria into the German Reich was based on his belief in the concept of a greater German nation, which included all German-speaking people.
Explanation: Hitler saw Austria as an essential part of this larger German nation and believed that it should be united with Germany. The larger plan that Hitler suggests the Anschluss (the annexation of Austria) is part of is the creation of a "Third Reich" or a "Greater Germany." Hitler envisioned a unified German-speaking empire that would include Austria, Germany, and other German-speaking territories. This expansionist plan aimed to consolidate all German-speaking people under one political entity, with Hitler as the leader. Hitler believed that the Anschluss would not only strengthen Germany's military and economic power but also provide a sense of unity and cultural identity to all German-speaking people. By incorporating Austria into the German Reich, Hitler sought to fulfill his vision of a dominant German nation, expand territorial control, and further his nationalist and racial ideologies. Overall, Hitler's reasoning for incorporating Austria into the German Reich was driven by his desire to create a unified German-speaking empire, known as the Third Reich, and to extend his influence and control over Europe.
