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 colonial empire
The German colonial empire () constituted the overseas colonies, dependencies and territories of Imperial Germany. The chancellor of this time period was Otto von Bismarck. Short-lived attempts of colonization by individual German states had occurred in preceding centuries, but crucial colonial efforts only began in 1884 with the Scramble for Africa. Claiming much of the left-over colonies that were yet unclaimed in the Scramble of Africa, Germany managed to build the third largest colonial empire after the British and the French, at the time. Germany lost control when World War I began in 1914 and its colonies were seized by its enemies in the first weeks of the war. However some military units held out for a while longer: German South West Africa surrendered in 1915, Kamerun in 1916 and German East Africa only in 1918 at the end of the war. Germany's colonial empire was officially confiscated with the Treaty of Versailles after Germany's defeat in the war and the various units became League of Nations mandates under the supervision (but not ownership) of one of the victorious powers.
