Anti-Semitism was Central to Nazi Propaganda
Some Austrians and Germans equated Jewish secularization with modernity and the rise of technology and this bred anxiety and fears of being "declassed" and "overwhelmed." Hitler himself spoke hysterically of "being overwhelmed by alien races, by fear of the 'locust-like immigration of Russian and Polish Jews'" and even "by fear that Germans would be 'exterminated'" (Fest 101).
Many historians have pointed out that, while European anti-Semitism had a long history going back centuries, it was in the 19th century that anti-Semitism took on a "racial" overtones in the pseudosciences of phrenology, physiognomy, and supposed biological "nature" (Fest, Arendt).
Nazi propaganda ultimately came to be based on idea of Volksgemeinschaft (equality of the people of the German “race”) and the persecution and attempted eradication of the Jewish “race” (Arendt 360).
