The Free State of Oldenburg (German: Freistaat Oldenburg) was a federated state that existed during the Weimar Republic and Nazi Germany. It was established in 1918 following the abdication of the Grand Duke Frederick Augustus II of the Grand Duchy of Oldenburg after the German Revolution and was abolished by the Allies following the Second World War.
