Free State of Saxe-Altenburg
German state (1918–1920)
The Free State of Saxe-Altenburg was a small, short-lived (1918–1920) central German state during the early years of the Weimar Republic. It was formed following the dissolution of the Duchy of Saxe-Altenburg during the German revolution of 1918–1919. After Duke Ernst II abdicated, Saxe-Altenburg transitioned peacefully into a republic. It became part of Thuringia when the state was created on 1 May 1920.
