Les Trente Glorieuses ("The Glorious Thirty") refers to the thirty years from 1945-1975 following the end of the Second World War in France. The name was first used by the French demographer Jean Fourastié. Fourastié coined the term in 1979 with the publication of his book Les Trente Glorieuses, ou la révolution invisible de 1946 à 1975 ("The Glorious Thirty, or the Invisible Revolution from 1946-1975"). The term is derived from Les Trois Glorieuses ("Three Glorious Days"), the three days of revolution on 27–29 July 1830 in France.
