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.

Germany rose again in world power status during the Third Reich (or Nazi Germany) under the dictatorship of Adolf Hitler between 1933 and 1945. It seized Austria and Czechoslovakia, and invaded Poland which launched World War II in Europe. In alliance with Italy and smaller Axis powers, Germany conquered most of Europe by 1940. Following the German invasion of the Soviet Union in 1941, the tide turned against the Third Reich as it suffered major military defeats in 1943; Germany was fully defeated by 1945.The Ottoman Empire during the 19th century was still a considerable power, with a great extension of territories over Europe, Asia and Africa; but the empire was in a condition of decline and during this period lost progressively its influence, and the majority of his territories were conquered by other powers. The empire ended during the First World War in 1918 when the Republic of Turkey was proclaimed.The Russian Empire as a state, existed from 1721 until it was declared a republic 1 September 1917.
