In 1865, France, Belgium, Italy, and Switzerland formed the Latin Monetary Union, in which they agreed to value their national currencies to a standard of 4.5 grams of fine silver or 0.290322 grams fine gold until 1934. Even after the monetary union faded away in the 1920s and officially ended in 1927, the Swiss franc remained on that standard until 27 September 1936, when it suffered its sole devaluation during the Great Depression. Following the devaluations of the British pound, U.S. dollar and French franc, the Swiss franc was devalued 30% to 0.20322 grams fine gold. In 1945, Switzerland joined the Bretton Woods system with its exchange rate to the dollar fixed until 1970.
