History of Germany during World War I
In November 1918, with internal revolution, a stalemated war, Bulgaria and the Ottoman Empire suing for peace, Austria-Hungary falling apart from multiple ethnic tensions, and pressure from the German high command, the Kaiser and all German ruling princes abdicated. On 9 November 1918, the Social Democrat Philipp Scheidemann proclaimed a Republic, in cooperation with the business and middle classes, not the revolting workers. The new government led by the German Social Democrats called for and received an armistice on 11 November 1918; in practice it was a surrender, and the Allies kept up the food blockade to guarantee an upper hand. The war was over; the history books closed on the German Empire. It was succeeded by the democratic, yet flawed, Weimar Republic.
Germanic Heroic Age
The period corresponds to the Germanic Wars in terms of historiography, and to the Germanic Iron Age in terms of archaeology, spanning the early centuries of the 1st millennium, in particular the 4th and 5th centuries, the period of the final collapse of the Western Roman Empire and the establishment of stable "barbarian kingdoms" larger than at the tribal level (the kingdoms of the Visigoths, the Franks and the Burgundians, and the Anglo-Saxon invasion of Britain). The Germanic peoples at the time lived mostly in tribal societies.
