Deposition of The Bishops
In 849 at a place called Coitlouh, Nominoe held a synod whereat he deposed the five Breton bishops of Alet, Saint-Pol, Vannes, Quimper, and Dol. The charges he levelled against them are unknown. Pope Leo IV sent a letter to Nominoe and the bishops (whether before or after the deposition is unknown) informing him that the depositions could only be enacted by a panel of twelve bishops with seventy-two witnesses. The later popes Benedict II and Nicholas I believed that Nominoe had forced the bishops to admit to crimes they had not committed and that their depositions were thus invalid. A Frankish synod of 850 held at either Angers or Tours accused Nominoe of simony by unlawfully removing bishops and replacing them with mercenarii (mercenaries of his own). These mercenarii were excommunicated, as indicated by an epistle of the synod of Savonnières in 859 sent to what remained of the Breton church in communion with the Archdiocese of Tours. Nominoe sacked Rennes and Nantes, replacing the new Frankish bishop of the latter with his own nominee.
Susannus was deposed in Vannes and replaced by Courantgen. Salocon was deposed in Dol, but his replacement is unknown. At Quimper, Felix was replaced by Anaweten and at Saint-Pol, Clutwoion replaced Garnobrius. The two bishops of Alet, first Rethwalatr and then Mahen are very obscure figures. The bishop of Nantes whom Nominoe succeeded in removing for about a year was Actard. His replacement was the obscure Gislard. In the end the synod of Coitlouh and the bringing of the bishoprics of Rennes and Nantes into the Breton fold meant that the church of Brittany was an actively independent ecclesiastic polity from its nominal metropolitan, the Metropolitan of Tours.
