A reformed Cistercian order instituted by Jean de la Barrière
in 1586. So called from the convent of Feuillans, in Languedoc, where
they were established in 1577.
The club of the Feuillants,
in the French Revolution, composed of moderate Jacobins. So called
because the convent of the Feuillants, near the Tuileries, was their
original club-room (1791-2).
