When did the German Empire fall?
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.
German Empire
Several of these states had gained sovereignty following the dissolution of the Holy Roman Empire, and had been de facto sovereign from the mid-1600s onward. Others were created as sovereign states after the Congress of Vienna in 1815. Territories were not necessarily contiguous—many existed in several parts, as a result of historical acquisitions, or, in several cases, divisions of the ruling families. Some of the initially existing states, in particular Hanover, were abolished and annexed by Prussia as a result of the war of 1866.
