Les Trente Glorieuses (, "The Glorious Thirty") refers to the thirty years from 1945 to 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 to 1975"). The term is derived from
Les Trois Glorieuses ("The Glorious Three"), the three days of revolution on 27–29 July 1830 in France.
