The Kapp Putsch, also known as the Kapp-Lüttwitz Putsch after its leaders Wolfgang Kapp and Walther von Lüttwitz, was an attempted coup on 13 March 1920 which aimed to undo the German Revolution of 1918–1919, overthrow the Weimar Republic and establish a right-wing autocratic government in its place. It was supported by parts of the Reichswehr (military) and other conservative, nationalist and monarchist factions.
