The Kapp Putsch, also known as the Kapp–Lüttwitz Putsch, was an attempted coup against the German national government in Berlin on 13 March 1920. Named after its leaders Wolfgang Kapp and Walther von Lüttwitz, its goal was to undo the German Revolution of 1918–1919, overthrow the Weimar Republic, and establish an autocratic government in its place. It was supported by parts of the Reichswehr, as well as nationalist and monarchist factions.
