In what way was the failure of Weimar Republic responsible for the introduction of Nazism?

Germans looked down upon the Weimar Republic which had signed such a disgraceful treaty of Versailles. The Germans could not reconcile with the democratic parliamentary system prevailing in their country. They preferred prestige and glory to liberty and freedom. They felt that only a strong man could restore the past prestige of Germany and check the rising popularity of Communism. When Hitler promised them all glory, they welcomed him with open arms.
