Historians regard the equation of National Socialism as 'Hitlerism' as too simplistic since the term was used prior to the rise of Hitler and the Nazis and the different ideologies incorporated into Nazism were already well established in certain parts of German society before World War I. The Nazis were strongly influenced by the post–World War I far-right in Germany, which held common beliefs such as anti-Marxism, anti-liberalism and antisemitism, along with nationalism, contempt for the Treaty of Versailles and condemnation of the Weimar Republic for signing the armistice in November 1918 which later led it to sign the Treaty of Versailles. A major inspiration for the Nazis were the far-right nationalist Freikorps, paramilitary organizations that engaged in political violence after World War I. Initially, the post–World War I German far-right was dominated by monarchists, but the younger generation, which was associated with Völkisch nationalism, was more radical and it did not express any emphasis on the restoration of the German monarchy. This younger generation desired to dismantle the Weimar Republic and create a new radical and strong state based upon a martial ruling ethic that could revive the "Spirit of 1914" which was associated with German national unity (Volksgemeinschaft).
