franc, originally a French coin but now the monetary unit of a number of countries, notably Switzerland, most French and former Belgian overseas territories, and some African states; at one time it was also the currency of France, Belgium, and Luxembourg. The name was first applied to a gold coin minted by King John II of France in 1360, which bore on one face the Latin legend Johannes Dei gratia Francorum rex (âJohn, by the grace of God, king of the Franksâ). Because this coin also carried the figure of the king on horseback, it was known as the franc Ă cheval to distinguish it from another coin of the same value later issued by Charles V of France. This latter coin was called the franc Ă pied because it showed the monarch on foot standing under a canopy. During the 17th century the minting of gold francs ceased, but the name was freely applied by the French public to the new unit of exchangeâthe livre tournois, a gold coin subdivided into 20 sols. In 1795, to symbolize the political changes that followed the French Revolution, the republican government introduced a new franc currency. The first coin was a five-franc silver piece; gold coins worth 20 francs (napoleons) were coined in quantity later. The livre tournois, which was exchangeable into the new currency at a rate of 81 livres to 80 francs, continued to circulate in France until 1834.
The franc was formally established as the monetary unit of France in 1799 and made divisible into 10 decimos and 100 centimes. The Swiss franc was adopted by Franceâs client state, the Helvetic Republic (made up of cantons of Switzerland), in 1799. The Belgian franc was adopted by Belgium in 1832, after independence. The Luxembourg franc was adopted in 1848 in place of the Dutch guilder. In 2002 the franc ceased to be legal tender in France, Belgium, and Luxembourg after the euro, the monetary unit of the European Union, became those countriesâ sole currency.
Most of Franceâs foreign colonies attained independence in the 1950s and early â60s, and many of the resulting Saharan and sub-Saharan African nations retained the name franc for their own basic monetary units. These countries, most of which formerly constituted French West Africa and French Equatorial Africa, became members of the Franc Zone; their currencies were linked to the French franc at a fixed rate of exchange and were freely convertible into that franc. In 1999, however, as France began to phase out the French franc, the currencies became linked to the euro.
