The Treaty of Versailles helped pave the way for the Nazi party to gain control of Germany by creating resentment and anger among the German people. Many German people were very resentful of their government (the Weimar Government) for having signed the peace Treaty in June 1919, since the terms of the Treaty were indeed very harmful to Germany: it took territory from the country, it forced it to pay reparations, and (and this term really caused indignation about the Germans) it blamed it and her allies for having started the war.
