High Middle Ages (11th century)
Feast: April 17
He kept founding monasteries, watching them grow lax, and leaving to start over. His last attempt — Citeaux — changed Western monasticism forever.
Robert was an abbot who couldn't stop starting over. He entered monastic life young and rose quickly, but every community he led eventually settled into comfort, and Robert couldn't stand it. He wanted the Benedictine Rule followed literally — real poverty, real manual labor, real silence. At Molesme, the abbey he founded in 1075, the early fervor gave way to the usual drift toward ease. Donations poured in, the monks hired servants, and the manual labor disappeared. Robert gathered a small group of monks who shared his frustration — Alberic and Stephen Harding among them — and in 1098, they walked out. They settled at Citeaux, a swampy, miserable piece of land south of Dijon that nobody else wanted. That was the point. They called themselves 'the new monastery' and committed to Benedict's Rule without shortcuts: no tithes, no feudal income, just what they could grow with their own hands. It nearly killed them. Recruits were few. Disease was common. Then, in a twist Robert didn't see coming, the monks of Molesme petitioned Rome to get their abbot back. The Pope agreed, and Robert returned to Molesme in 1099. He spent the remaining twelve years of his life there. Citeaux, meanwhile, survived under Alberic and Stephen Harding, and when a young Burgundian nobleman named Bernard showed up in 1113 with thirty friends, the Cistercian movement exploded. Robert had planted the seed. Others harvested it.
