Hitler believed that Aryans were the superior race, while he thought Jewish people were the cause of Germany's problems and held very high prejudice against them.
Adolf Hitler believed that Aryan citizens were the superior race and planned to pretty much take over the world with Aryan soldiers. Aryan people were classified as German citizens with blonde hair and blue eyes, even though Hitler himself did not meet this criteria. Hitler supported this "master race" and wanted Aryan people to produce Aryan children for war purposes.
On the other hand, Hitler believed that Jews were the root cause of Germany's problems and the reason why they lost World War I. It is also believed that Hitler was raised with anti-Semitic views that stayed with him through adulthood and became progressively more powerful.
