Thus the quarrel had come to a head. Church and State were at open war. Henry soon found that Becket's threats had more effect than he liked. Many of the English clergy were naturally on the side of the primate in a dispute which touched their loyalty to the Church and their class feeling. Several bishops declared to the king that, since his ministers had been duly excommunicated, they did not see how they could avoid regarding them as men placed outside the pale of Christendom. Fortunately the pope interfered for a moment to lighten the friction; being threatened with a new invasion by the emperor Frederick, he suspended the sentences and sent legates to patch up a peace. They failed, for neither the king nor the archbishop would give way. At this juncture Henry was desirous of getting his eldest son and namesake crowned as his colleague, the best mode that he could devise for avoiding the dangers of a disputed succession at his death. He induced the archbishop of York, assisted by the bishops of London and Salisbury, to perform the ceremony. This was a clear invasion of the ancient rights of the primate, and Becket took it more to heart than any other of his grievances. Yet the next move in the struggle was a hollow reconciliation between the combatants--a most inexplicable act on both sides. The king offered to allow Becket to return from exile, and to restore him to his possessions, without exacting from him any promise of submission, or even a pledge that he would not reopen the dispute on his return. Apparently he had made a wrong interpretation of the primate's mental attitude, and thought him desirous of a truce, if not ready for a compromise. He had wholly misjudged the situation; Becket made neither promises nor threats, but three weeks after he reached Canterbury publicly excommunicated the bishops of London and Salisbury for the part that they had taken in the coronation of the young king, and suspended from their functions the other prelates who had been present at the ceremony. He then proceeded to excommunicate a number of his minor lay enemies. Becket's murder.
