The stab-in-the-back myth was an antisemitic conspiracy theory that was widely believed and promulgated in Germany after 1918. It maintained that the Imperial German Army did not lose World War I on the battlefield, but was instead betrayed by certain citizens on the home front – especially Jews, revolutionary socialists who fomented strikes and labour unrest, and republican politicians who had overthrown the House of Hohenzollern in the German Revolution of 1918–1919. Advocates of the myth denounced the German government leaders who had signed the Armistice of 11 November 1918 as the "November criminals".

The German Revolution of 1918–1919, also known as the November Revolution, was an uprising started by workers and soldiers in the final days of World War I. It quickly and almost bloodlessly brought down the German Empire, then in its more violent second stage, the supporters of a parliamentary republic were victorious over those who wanted a soviet-style council republic. The defeat of the forces of the far Left cleared the way for the establishment of the Weimar Republic.
