The Feuillants were a Catholic congregation originating in the 1570s as a reform group within the Cistercians in its namesake Les Feuillants Abbey in France, which declared itself an independent order.
In 1630 it separated into a French branch (the Congregation of Our Lady of the Feuillants) and an Italian branch (the Reformed Bernardines or Bernardoni).
The French order was suppressed in 1791 during the French Revolution, but gave its name to the Club des Feuillants. The Italian order later rejoined the Cistercians.
