Odo of Cluny was a 10th-century Benedictine monk who served as the second abbot of Cluny. Born in Le Mans around 878, he was raised in noble circles and served as a page before becoming a canon in Tours. Disillusioned by the laxity of the clergy, he transitioned to monastic life at Baume. Following the death of Abbot Berno in 927, Odo took leadership of Cluny, where he spearheaded a significant reform movement aimed at restoring strict adherence to the Rule of Saint Benedict throughout Western Europe.
