This document outlines several theories on the rise of the Nazis in Germany: 1) A crisis of capitalism theory that links the 1929 economic crash to business support for the Nazis. 2) Anti-German determinism theories that portray Nazism as the inevitable result of German history and culture. 3) A "moral crisis" theory arguing that World War 1 destabilized European society and enabled the rise of Nazism. 4) Structuralist theories emphasize preexisting authoritarian tendencies in German society and institutions that facilitated Hitler's rise to power.
