From 1920 to 1935, as a result of World War I, the region was under the control of the League of Nations as the Territory of the Saar Basin. The Saar Protectorate (German: Saarprotektorat; French: Protectorat de Sarre) was a short-lived protectorate (1947–1956) partitioned from Germany after its defeat in World War II; it was administered by the French Fourth Republic. On rejoining West Germany in 1957, it became the smallest "area state" of the Federal Republic of Germany.
The Saar franc was the currency of the Saar Protectorate and, later, the state of Saarland in the Federal Republic of Germany between 20 November 1947 and 6 July 1959. It was valued at par with the French franc, and French coins and banknotes circulated alongside local issues. Saar franc refers to the French franc (German: Franken) used as the official currency of the Saar during the two times that the Saar territory was economically split off from Germany, i.e. 1920–1935 as the Territory of the Saar Basin; and 1947–1957 as the Saar Protectorate and 1957–1959 as the state of Saarland in West Germany. Although local notes and coins were issued during both periods, legally the Saar franc was never an independent currency. It was not before 1954 when the government of the Protectorate issued new coins denominated in 10, 20, 50 and 100 francs. But the coins resembled the coins of the French franc and were officially and legally not a currency of their own, but only local issues of the French franc.
