Abdication of Wilhelm II
The abdication of Wilhelm II as German Emperor and King of Prussia was declared by Chancellor Maximilian of Baden on 9 November 1918; it was formally affirmed by a written statement of Wilhelm on 28 November, made while in exile in Amerongen, the Netherlands. The abdication caused the German Empire to dissolve and concluded the House of Hohenzollern's 500-year rule over Prussia and its predecessor state, Brandenburg. Wilhelm reigned from 15 June 1888 to 9 November 1918. As a result of the abdication and the German Revolution of 1918–19, the nobility as a legally-defined class was abolished. Following the proclamation of the Weimar Constitution on 11 August 1919, all Germans were declared equal before the law. The rulers of the twenty-two constituent states of the Empire also had to relinquish their monarchical titles and domains.
