The Hussards was a literary movement the 'members' of which never recognised the term itself, and not did they see themselves as part of a movement. The expression was originally used in 1952 by the writer and journalist Bernard Frank in Les Temps Modernes to describe a group of strongly right-wing writers who were anti-Sartrean and anti-Gaullist. Under this umbrella come Roger Nimier (who published Le Hussard bleu in 1950 and of course inadvertently gave the name to the group of writers), Jacques Laurent, Antoine Blondin, Michel Déon, Jacques Chardonne, Paul Morand, and so on.
