Moreover, this anger was directed towards those who were not considered "German," including other Europeans and minorities living in German territory. Finally, Germans felt that the reparations that were placed on them by the Allies were too harsh, and that they were designed to lead Germany to ruin. All of these factors were significant in the rise of the Nazi Party.
