1955 Saar Statute referendum
A referendum on the Saar statute was held in the Saar Protectorate on 23 October 1955. The statute would make the territory independent under the auspices of a European Commissioner to be appointed by the Council of Ministers of the Western European Union, while remaining in the economic union with France.
Its rejection by voters was taken as an indication that they would rather reunite with West Germany. So on 27 October 1956 France and West Germany concluded the Saar Treaty establishing that Saarland should be allowed to join West Germany, as provided by its Grundgesetz constitution article 23 and so Saarland did as a state of Germany with effect of 1 January 1957.
