(Catholic Association of French Youth) Organization founded, 1886, by Robert de Roquefeuil and six other students, at the suggestion of Albert de Mun, in order to unite Catholic youth of France in cooperative effort for the reestablishment of Christian social order. Non-political and without social distinctions, its program is formulated in its motto, "Piety, Study, Action." In 1914 it counted 4000 groups with 150,000 members, and, despite heavy war casualties, it still flourishes.
