Saint Gerard of Clairvaux (died 1138) was the older brother of Bernard of Clairvaux. He was the son of Tescelin le Roux and Aleth de Montbard. When Bernard entered Cîteaux with a group of young relatives and friends in 1112, Gerard did not join him. Instead, he participated in the military life, but was injured during a siege of Grancy and was also imprisoned. During his imprisonment, he decided to enter the monastic life and went to Citeaux after his release.
His brother appointed him cellarer and Gerard managed the domestic affairs of abbey. He is said to have become so skillful in manual occupations that builders, smiths, shoemakers, and weavers went to him for advice and instruction. On his way to Rome in 1137 he fell ill at Viterbo. However, he recovered and returned to France but died the next year.
Alberic of Cîteaux, O.Cist. (died January 26, 1109), sometimes known as Aubrey of Cîteaux, was a French monk and abbot, one of the founders of the Cistercian Order. He is now honored as a saint.
Saint Nivard (Nivo) was bishop of Reims before 657 and until 673. He was brother-in-law of Childeric II. He restored Hautvilliers Abbey and was later buried there.
Bernard of Clairvaux (Latin: Bernardus Claraevallensis), O.Cist (1090 – 20 August 1153) was a French abbot and the primary reformer of the Cistercian order.
After the death of his mother, Bernard sought admission into the Cistercian order. “Three years later, he was sent to found a new abbey at an isolated clearing in a glen known as the Val d’Absinthe, about 15 kilometres (9.3 mi) southeast of Bar-sur-Aube. According to tradition, Bernard founded the monastery on 25 June 1115, naming it Claire Vallée, which evolved into Clairvaux. There Bernard would preach an immediate faith, in which the intercessor was the Virgin Mary.” In the year 1128, Bernard attended the Council of Troyes, at which he traced the outlines of the Rule of the Knights Templar, which soon became the ideal of Christian nobility.
Elected to the papacy in 1254, Rinaldo, the count of Segni, took the name Alexander IV. A native of Anagni, he was born in 1199 and became a cardinal deacon in 1227. In 1231, he was made cardinal bishop of Ostia, and he served under Innocent IV as cardinal protector of the Franciscans. Alexander inherited Innocent’s quarrel with Manfred, the illegitimate son of Frederick II. In a struggle over the crown of Sicily, Alexander excommunicated Manfred in 1255. The two waged war for the rest of Alexander’s reign, which ended with his death in 1261. The energy and resources spent against Manfred kept Alexander from realizing his dream of crusading against the Mongols. Alexander did, however, bless the Augustinian hermits and canonize Clare of Assisi.
