Hincmar of Rheims

Hincmar (/ˈhɪŋkmɑːr/; 806 – 21 December 882), archbishop of Reims, was the friend, advisor and propagandist of Charles the Bald. He belonged to a noble family of northern Francia.

Hincmar was born in 806 to a distinguished family of the West Franks. Destined to the monastic life, he was brought up at Saint-Denis under the direction of the abbot Hilduin (died 844), who, went appointed court chaplain in 822, brought him to the court of the emperor Louis the Pious. There he became acquainted with the political as well as the ecclesiastical administration of the empire. When Hilduin was disgraced in 830 for having joined the party of Lothair I, Hincmar accompanied him into exile at Corvey in Saxony. Hincmar used his influence with the emperor on behalf of the banished abbot, and not without success: for he stood in high favour with Louis the Pious, having always been a faithful and loyal adherent. He returned with Hilduin to Saint-Denis when the abbot was reconciled with the emperor and remained faithful to the Louis during his struggle with his sons.

After the death of Louis the Pious (840) Hincmar supported Charles the Bald (see Capitularies of Charles the Bald), and received from him the abbacies of Nôtre-Dame at Compiègne and Saint-Germer-de-Fly.

Archbishop Ebbo had been deposed in 835 at the synod of Thionville (Diedenhofen) for having broken his oath of fidelity to the emperor Louis, whom he had deserted to join the party of Lothair. After the death of Louis, Ebbo succeeded in regaining possession of his see for some years (840-844), but in 844 Pope Sergius II confirmed his deposition. In 845 Hincmar obtained through the king's support the archbishopric of Reims, and this choice was confirmed at the Synod of Beauvais (April 845). He was consecrated archbishop on 3 May 845; in 847 Pope Leo IV sent him the pallium.
