All the accusations with regard to Gregory that Candidus could come up with were well received by the assembly, which committed itself to the resolution that Gregory had forfeited the papacy. In one document full of accusations, the bishops renounced their allegiance to Gregory. In another, Henry pronounced him deposed, and the Romans were required to choose a new pope. The council sent two bishops to Italy, and they procured a similar act of deposition from the Lombard bishops at the synod of Piacenza. Roland of Parma informed the pope of these decisions, and he was fortunate enough to gain an opportunity for speech in the synod, which had just assembled in the Lateran Basilica, to deliver his message there announcing the dethronement. For the moment the members were frightened, but soon such a storm of indignation was aroused that it was only due to the moderation of Gregory himself that the envoy was not murdered. On the following day, 22 February 1076, Pope Gregory VII pronounced a sentence of excommunication against Henry IV with all due solemnity, divested him of his royal dignity and absolved his subjects from the oaths they had sworn to him. This sentence purported to eject a ruler from the Church and to strip him of his crown. Whether it would produce this effect, or would be an idle threat, depended not so much on Gregory VII as on Henry's subjects, and, above all, on the German princes. Contemporary evidence suggests that the excommunication of Henry made a profound impression both in Germany and Italy. Thirty years before, Henry III had deposed three claimants to the papacy, and thereby rendered an acknowledged service to the Church. When Henry IV tried to copy this procedure he was less successful, as he lacked the support of the people. In Germany there was a rapid and general feeling in favor of Gregory, and the princes took the opportunity to carry out their anti-regal policy under the cloak of respect for the papal decision. When at Whitsun the king proposed to discuss the measures to be taken against Gregory VII in a council of his nobles, only a few made their appearance; the Saxons snatched at the golden opportunity for renewing their rebellion, and the anti-royalist party grew in strength from month to month. The situation now became extremely critical for Henry. As a result of the agitation, which was zealously fostered by the papal legate Bishop Altmann of Passau, the princes met in October at Trebur to elect a new German ruler.
