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.
List of current pretenders
The German Empire was a federation of a score of smaller monarchies, all of which are now abolished under modern republican Germany although a handful never abdicated their titles. As a result, there are a large number of claimants to various German thrones. Since the dissolution of the empire, however, a number of former royal households have become extinct in the male line, and are therefore not represented in the list below. Mecklenburg–Schwerin became extinct in 2001, Saxe-Altenburg in 1991, and Schwarzburg-Rudolstadt and Schwarzburg-Sondershausen in 1971.
