Bernard of Vienne was a ninth-century Benedictine monk who served as the archbishop of Vienne starting in 810. Originally a soldier serving under Charlemagne, the loss of his parents influenced him to dedicate his wealth to charitable causes, including support for the church and the poor. After purchasing the monastery at Ambronay, where he acted as abbot, he eventually rose to his episcopal position. He remained a supporter of Frankish imperial unity throughout his career, even aligning with Lothair I during political tensions with Louis the Pious.
Life and career

Following his military service, Bernard transitioned to monastic life by acquiring the monastery in Ambronay. His political involvement led to a confrontation at the Synod of Thionville, where he was deposed for supporting Lothair I against Louis the Pious, though this removal was never executed. He spent his final years living near the Isère river in the area now known as Romans-sur-Isère.
Veneration
Recognized as a saint within the Catholic Church, Bernard is commemorated on January 22. His legacy is tied to his early commitment to charity and his leadership within the Benedictine order and the archdiocese.
