Prejudice toward Jews had existed in Germany for hundreds of years, resulting in exile, loss of life, property and hatred. Hitler blamed Jews for his own personal failures and also for Germany's problems. These false accusations became persuasive parts of Nazi propaganda, especially when they were blended with Hitler's master race theories. He believed that Aryans were a master race who should rule people like Jews and Slavs because they weren't like them. . He believed that the ideal Aryan was German, not Jewish, blonde, blue eyed, and tall. Therefore, most Nazi leaders, including Hitler, saw the Jews as a terrible race not just a religious group.
