In 1854, Luxembourg began issuing its own franc, at par with the Belgian franc. The Luxembourg franc followed the Belgian franc into the Latin Monetary Union in 1865. In 1926, Belgium withdrew from the Latin Monetary Union. However, the 1921 monetary union of Belgium and Luxembourg survived, forming the basis for the full Belgium-Luxembourg Economic Union in 1932.
