Synod of Ingelheim
The Universal Synod of Ingelheim began on June 7, 948 in the then church of Saint Remigius in Ingelheim. Being summoned by Pope Agapetus II its primary goal was to resolve a long running Schism concerning the archiepiscopal see of Reims. The synod was presided by Marinus of Bomarzo, then the Roman Church's librarian. In the run up to the convocation there were two earlier synods, in Verdun in November 947 and in Mouzon in the beginning of 948, both considering the same problem but unable to resolve it.
