: : I don't think anyone can point to a certain reason for the Nazi's rise to power, and it is very unlikely it was beacause of the German people "humiliation" in the Treaty of Versai. After all- the Fascist party also rose to power in Italy, and Italy was on the winners side in WWI (and still felt underpaied).
: Keep in mind that Germany was not the agressor in the begining of WWI. It was the smaller countries and all the secret treaties that led to Germany's, England's and France's ultimate involvement in the war. At the end, Germany was forced to take the blame for the war, and forced to make reparations and aquiences that were rather extreme. The Treat of Versailles was a very big slap in the face of the Germans, and when the details of the treaty were announced the German army very nearly went back to war.
:: The Treaty of Versailles was actually a great deal milder than many people realise. The reparations that were levied on Germany worked out at a great deal less per year than those which Germany levied on France in 1871. Germany's territorial losses were slight and still left her as a great power in Central Europe. By contrast, when Russia surrendered to Germany in 1918, her territorial losses amounted to about a quarter of the country.
