Passage: Around 4 November, delegations of the sailors dispersed to all of the major cities in Germany. By 7 November, the revolution had seized all large coastal cities as well as Hanover, Brunswick, Frankfurt on Main, and Munich. In Munich, a "Workers' and Soldiers' Council" forced the last King of Bavaria, Ludwig III, to abdicate. Bavaria was the first member state of the German Empire to be declared a Volksstaat, the People's State of Bavaria, by Kurt Eisner of the USPD. In the following days, the dynastic rulers of all the other German states abdicated; the last was Günther Victor, Prince of Schwarzburg, on 23 November.
