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.
List of the Germanic Wars
This is a list of the Germanic Wars between various Germanic tribes, the Romans and their descendants between 113 BC and 600 AD. The nature of these wars varied through time between Roman and Byzantine conquest, Germanic uprisings and later Germanic invasions in the Roman Empire that started in the late 2nd century. The series of conflicts which began in the 5th century, under the Western Roman Emperor Honorius, led (along with internal strife) to the ultimate downfall of the Western Roman Empire.
