Militarism in Germany continued after World War I and the fall of the German monarchy in the German Revolution of 1918–19, in spite of Allied attempts to crush German militarism by means of the Treaty of Versailles, as the Allies saw Prussian and German militarism as one of the major causes of the Great War. During the period of the Weimar Republic (1918–1933), the 1920 Kapp Putsch, an attempted coup d'état against the republican government, was launched by disaffected members of the armed forces. After this event, some of the more radical militarists and nationalists were submerged in grief and despair into the NSDAP party of Adolf Hitler, while more moderate elements of militarism declined and remained affiliated with the German National People's Party (DNVP) instead.
