German Empire
The high command under Paul von Hindenburg and Erich Ludendorff increasingly controlled the country, but in October after the failed offensive in spring 1918, the German armies were in retreat, allies Austria-Hungary and the Ottoman Empire had collapsed, and Bulgaria had surrendered. The Empire collapsed in the November 1918 Revolution with the abdications of its monarchs. This left a postwar federal republic and a devastated and unsatisfied populace, which later led to the rise of Adolf Hitler and Nazism.

In the face of the increasingly violent conflicts between the communists and Nazis, the growing polarisation of the German population and a multitude of other factors, mainly the drastic economic sinking, extreme hyperinflation and corruption of the republic, the Weimar Republic collapsed in 1933 with the Nazi seizure of power () and the appointment of Adolf Hitler as German chancellor.
