Majolus of Cluny was a tenth-century Benedictine monk who served as the fourth abbot of the Cluny Abbey in France. Born into a wealthy family near Avignon around 910, he initially served as a canon and archdeacon in Mâcon before joining the monastic community at Cluny. As an influential leader, he worked to reform various religious communities, often by affiliating them with the motherhouse at Cluny to ensure stability. He was a trusted advisor to the Holy Roman Emperors, helping to mediate political disputes and providing spiritual guidance to the imperial court.
