It is interesting to notice, in view of the conflict on investitures which was before long to begin in England, and which had already been for years so bitterly fought upon the continent, that all these events happened without the slightest questioning on the part of any one of the king's sole right to dispose of the highest see of the realm as he pleased. There was no suggestion of the right of election, no objection to lay investiture, no protest from any one. Anselm accepted investiture with the staff from the hand of the king without remark. He acknowledged his feudal relation to him, swore fealty to him as a vassal,[15] and was ready to perform his obligations of feudal service, at least upon his own interpretation of their extent. A little later, in 1095, after the first serious conflict between himself and the king, when the papal legate in England took of him his oath of fealty to the pope, the oath contained the usual Norman clause reserving his fealty to the king. A clause in the bishop's oath to the pope so unusual as this could not have passed in that age without notice. It occasioned instant criticism from strict ecclesiastics on the continent, and it must have been consciously inserted by Anselm and consciously accepted by the legate. Such facts as these, combined with the uncompromising character of Anselm, are more striking evidence of the absolutism of the Norman monarchy than anything which occurred in the political world during this period. Within a few days after his consecration, Anselm set out from Canterbury to attend the Christmas meeting of the king's court at Gloucester. There he was well received by the king, but the most important business before the court was destined to lead to the first breach between them. Robert of Normandy had grown tired of his brother's long delay in keeping the promises which he had made in the treaty of Caen. Now there appeared at Gloucester a formal embassy from him, authorized to declare William forsworn and faithless, and to renounce all peace and agreement with him unless he held to the treaty or exculpated himself in due form. There could be no hesitation about an answer to this demand. It is more than likely that William himself, within a short time, would have sought for some excuse to begin again his conquest of Normandy, if Robert had not furnished him this one. War was at once resolved upon, and preparations made for an immediate campaign. The most important preliminary question, both for William and for England, was that of money, and on this question the scruples of Anselm and the will of the king first came into collision. Voluntary aids, donations of money for the special undertakings or necessities of the king, were a feature of William's financial management, though their voluntary character seems often to have been more a matter of theory than of reality. If the sum offered was not so large as the king expected, he refused to accept it and withdrew
