What was at the core of Hitlers ideas?

At the core of Hitler's ideas was a belief in the superiority of the Aryan race, particularly the Germanic peoples, which he viewed as destined to dominate other races. This ideology fueled his virulent anti-Semitism, which blamed Jews for many of Germany's social and economic issues. Additionally, Hitler promoted nationalism and militarism, advocating for the expansion of German territory to provide "living space" (Lebensraum) for the Aryan population. His ideas ultimately led to the horrors of the Holocaust and World War II.
