HINCMAR (c. 805-882), archbishop of Reims, one of the most remarkable figures in the ecclesiastical history of France, belonged to a noble family of the north or north-east of Gaul. Destined, doubtless, to the monastic life, he was brought up at St Denis under the direction of the abbot Hilduin (d. 844), who brought him in 822 to the court of the emperor Louis the Pious. When Hilduin was disgraced in 830 for having joined the party of Lothair, Hincmar accompanied him into exile at Corvey in Saxony, but returned with him to St Denis when the abbot was reconciled with the emperor, and remained faithful to the emperor during his struggle with his sons. After the death of Louis the Pious (840) Hincmar supported Charles the Bald, and received from him the abbacies of Notre-Dame at Compiegne and St Germer de Fly. In 845 he obtained through the king's support the archbishopric of Reims, and this choice was confirmed at the synod of Beauvais (April 845). Archbishop Ebbo, whom he replaced, had been deposed in 835 at the synod of Thionville ( D iedenhof en) for having broken his oath of fideli ty 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. It was in these circumstances that Hincmar succeeded, and in 847 Pope Leo IV. sent him the pallium.
One of the first cares of the new prelate was the restitution to his metropolitan see of the domains that had been alienated under Ebbo and given as benefices to laymen. From the beginning of his episcopate Hincmar was in constant conflict with the clerks who had been ordained by Ebbo during his reappearance. These clerks, whose ordination was regarded as invalid by Hincmar and his adherents, were condemned in 853 at the council of Soissons, and the decisions of that council were confirmed in 855 by Pope Benedict III. This conflict, however, bred an antagonism of which Hincmar was later to feel the effects. During the next thirty years the archbishop of Reims played a very prominent part in church and state. His authoritative and energetic will inspired, and in great measure directed, the policy of the west Prankish kingdom until his death. He took an active part in all the great political and religious affairs of his time, and was especially energetic in defending and extending the rights of the church and of the metropolitans in general, and of the metropolitan of the church of Reims in particular. In the resulting conflicts, in which his personal interest was in question, he displayed great activity and a wide knowledge of canon law, but did not scruple to resort to disingenuous interpretation of texts. His first encounter was with the heresiarch Gottschalk, whose predestinarian doctrines claimed to be modelled on those of St Augustine. Hincmar placed himself at the head of the party that regarded Gottschalk's doctrines as heretical, and succeeded in procuring the arrest and imprisonment of his adversary (849). For a part at least of his doctrines Gottschalk found ardent defenders, such as Lupus of Ferrieres, the deacon Florus and Amolo of Lyons. Through the energy and activity of Hincmar the theories of Gottschalk were condemned at Quierzy (853) and Valence (855), and the decisions of these two synods were confirmed at the synods of Langres and Savonnieres, near Toul (859). To refute the predestinarian heresy Hincmar composed his De praedeslinalione Dei el libero arbilrio, and against certain propositions advanced by Gottschalk on the Trinity he wrote a treatise called De una el non trina deflate. Gottschalk died in prison in 868. The question of the divorce of Lothair II., king of Lorraine, who had repudiated his wife Theutberga to marry his concubine Waldrada, engaged Hincmar's literary activities in another direction. At the request of a number of great personages in Lorraine he composed in 860 his De diwrlio Lotharii et Teutbergae, in which he vigorously attacked, both from the moral and the legal standpoints, the condemnation pronounced against the queen by the synod of Aix-la-Chapelle (February 860). Hincmar energetically supported the policy of Charles the Bald in Lorraine, less perhaps from devotion to the king's interests than from a desire to see the whole of the ecclesiastical province of Reims united under the authority of a single sovereign, and in 869 it was he who consecrated Charles at Metz as king of Lorraine.
In the middle of the 9th century there appeared in Gaul the collection of false decretals commonly known as the PseudoIsidorian Decretals. The exact date and the circumstances of the composition of the collection are still an open question, but it is certain that Hincmar was one of the first to know of their existence, and apparently he was not aware that the documents were forged. The importance assigned by these decretals to the bishops and the provincial councils, as well as to the direct intervention of the Holy See, tended to curtail the rights of the metropolitans, of which Hincmar was so jealous. Rothad, bishop of Soissons, one of the most active members of the party in favour of the pseudoIsidorian theories, immediately came into collision with his archbishop. Deposed in 863 at the council of Soissons, presided over by Hincmar, Rothad appealed to Rome. Pope Nicholas I. supported him zealously, and in 865, in spite of the protests of the archbishop of Reims, Arsenius, bishop of Orta and legate of the Holy See, was instructed to restore Rothad to his episcopal see. Hincmar experienced another check when he endeavoured to prevent Wulfad, one of the clerks deposed by Ebbo, from obtaining the archbishopric of Bourges with the support of Charles the Bald. After a synod held at Soissons, Nicholas I. pronounced himself in favour of the deposed clerks, and Hincmar was constrained to make submission (866). He was more successful in his contest with his nephew Hincmar, bishop of Laon, who was at first supported both by the king and by his uncle, the archbishop of Reims, but soon quarrelled with both. Hincmar of Laon refused to recognize the authority of his metropolitan, and entered into an open struggle with his uncle, who exposed his errors in a treatise called Opusculum LV. capilulorum, and procured his condemnation and deposition at the synod of Douzy (871). The bishop of Laon was sent into exile, probably to Aquitaine, where his eyes were put out by order of Count Boso. Pope Adrian protested against his deposition, but it was confirmed in 876 by Pope John VIII., and it was not until 878, at the council of Troyes, that the unfortunate prelate was reconciled with the Church. A serious conflict arose between Hincmar on the one side and Charles and the pope on the other in 876, when Pope John VIII., at the king's request, entrusted Ansegisus, archbishop of Sens, with the primacy of the Gauls and of Germany, and created him vicar apostolic. In Hincmar's eyes this was an encroachment on the jurisdiction of the archbishops, and it was against this primacy that he directed his treatise Dejure metropolitanorum. At the same time he wrote a life of St Remigius, in which he endeavoured by audacious falsifications to prove the supremacy of the church of Reims over the other churches. Charles the Bald, however, upheld the rights of Ansegisus at the synod of Ponthion. Although Hincmar had been very hostile to Charles's expedition into Italy, he figured among his testamentary executors and helped to secure the submission of the nobles to Louis the Stammerer, whom he crowned at Compiegne (8th of December 877).
During the reign of Louis, Hincmar played an obscure part. He supported the accession of Louis III. and Carloman, but had a dispute with Louis, who wished to instal a candidate in the episcopal see of Beauvais without the archbishop's assent. To Carloman, on his accession in 882, Hincmar addressed his De ordine palatii, partly based on a treatise (now lost) by Adalard, abbot of Corbie (c. 814), in which he set forth his system of government and his opinion of the duties of a sovereign, a subject he had already touched in his De regis persona et regio ministerio, dedicated to Charles the Bald at an unknown date, and in his Instructio ad Ludovicum regent, addressed to Louis the Stammerer on his accession in 877. In the autumn of 882 an irruption of the Normans forced the old archbishop to take refuge at Epernay, where he died on the 21st of December 882. Hincmar was a prolific writer. Besides the works already mentioned, he was the author of several theological tracts; of the De villa Noviliaco, concerning the claiming of a domain of his church; and he continued from 86 1 the Annales Bertiniani, of which the first part was written by Prudentius, bishop of Troyes, the best source for the history of Charles the Bald. He also wrote a great number of letters, some of which are extant, and others embodied in the chronicles of Flodoard.
Hincmar's works, which are the principal source for the history of his life, were collected by Jacques Sirmond (Paris, 1645), and reprinted by Migne, Patrol. Latina, vol. cxxy. and cxxvi.
