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.
History of Germany
By September 1945, Nazi Germany and its Axis partners (Italy and Japan) had all been defeated, chiefly by the forces of the Soviet Union, the United States, and Great Britain. Much of Europe lay in ruins, over 60 million people worldwide had been killed (most of them civilians), including approximately 6 million Jews and 5 million non-Jews in what became known as the Holocaust. World War II resulted in the destruction of Germany's political and economic infrastructure and led directly to its partition, considerable loss of territory (especially in the East), and historical legacy of guilt and shame.
