Bernard was born near Dijon, in France, in 1090, of a noble family. In 1112 he joined the new monastery at Cîteaux. This had been founded fourteen years before, in a bid to reject the laxity and riches of the Benedictine Order (as exemplified by great monasteries such as Cluny) and to return to a primitive poverty and austerity of life.
Bernard was a man of great holiness and wisdom, and although he was often in very poor health, he was active in many of the great public debates of the time.
By the time of his death, the Cistercian Order had grown from one house to 343, of which 68 were daughter houses of Clairvaux itself.
