Cistercians, a monastic order founded by Abbot Robert in 1098 at Citeaux, near Dijon; they followed the rule of St. Benedict, who reformed the Order after it had lapsed; became an ecclesiastical republic, and were exempt from ecclesiastical control; contributed considerably to the progress of the arts, if little to the sciences.
