There is a contemporary tract, Altercatio inter Urbanum et Clementum, arguing the two popes claims should be adjudicated by a council. In March 1095 Conrad attended the Council of Piacenza and confirmed his stepmother Eupraxia's accusations that Henry IV was a member of a Nicolaitan sect, participated in orgies and had offered Eupraxia to **Conrad**, stating that this was the reason for _ turning against his father.
