Concept note-1: -Under the Treaty of Versailles, the highly industrialized Saar Basin, including the Saar Coal District (German: Saarrevier), was to be occupied and governed by the United Kingdom and France under a League of Nations mandate for a period of fifteen years. Its coalfields were also to be ceded to France.
Concept note-2: -At the end of 15 years, a plebiscite was to be held to determine the final status of the Saar. This vote took place on January 13, 1935. More than 90 percent of the voters favored the immediate reintegration of the Saar into Germany, which duly took effect on March 1, 1935.
Concept note-3: -Complete answer: The Alsace-Lorraine region was the genuine prize for France. Even after Germany’s deceptions, the local community was always eager to be associated with France. For the next 15 years, France will have complete ownership of the coalfields in the SAAR basin.
Concept note-4: -Following World War II, the French military administration in Allied-occupied Germany organized the territory as the Saar Protectorate on 16 February 1946. After the 1955 Saar Statute referendum, it joined the Federal Republic of Germany as a state on 1 January 1957.
