After the Russian Revolution of 1917, the Spartacus League began agitating for a similar course: a government based on local workers' councils, in Germany. After the abdication of the Kaiser in the German Revolution of November 1918, a period of instability began, which lasted until 1923. On 9 November 1918, from a balcony of the Kaiser's Berliner Stadtschloss, Liebknecht declared Germany a "Free Socialist Republic". However, earlier on the same night, Philipp Scheidemann of the SPD had declared a republic from the Reichstag.
