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.
North German Confederation
The North German Confederation () was the German federal state which existed from July 1867 to December 1870. Some historians also use the name for the alliance of 22 German states formed on 18 August 1866 (""). In 1870–1871, the south German states of Baden, Hesse-Darmstadt, Württemberg and Bavaria joined the country. On 1 January 1871, the country adopted a new constitution, which was written under the title of a new "German Confederation" but already gave it the name "German Empire" in the preamble and article 11. As the state system largely remained the same in the German Empire, the North German Confederation continues as the German nation state which still exists.
