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.
German Confederation
The German Confederation () was an association of 39 German-speaking states in Central Europe (adding the mainly non-German speaking Kingdom of Bohemia and Duchy of Carniola), created by the Congress of Vienna in 1815 to coordinate the economies of separate German-speaking countries and to replace the former Holy Roman Empire, which had been dissolved in 1806. The German Confederation excluded German-speaking lands in the eastern portion of the Kingdom of Prussia (East Prussia, West Prussia and Posen), the German cantons of Switzerland, and Alsace within France which was majority German speaking.
