Charlemagne could not but acknowledge that he had been greatly indebted to the exertions of the churchmen for the pacification of his Saxon acquisitions; and in requital of this co-operation he was not inclined to deny to his spiritual allies an important share in the profits of victory. But the consciousness of present power shut out any sinister view to the future. The church was, after all, in his hands no more than an instrument for the accomplishment of his purposes; that she should ever become his mistress was remote from his contemplation; and it is not to be wondered at that he should have identified her interests with those of his government in that spirit of gratitude which might in the sequel be made to wear an aspect of homage very conducive to the progress of hierarchical pretension.
Both parties were in the main inclined to regard each other as the means and instruments for the promotion of their separate interests. But the absence of any real reciprocity in the terms of compact could not but very soon become apparent. No temporal benefit could be conferred by the pope commensurate with the sacrifices the monarch was incessantly called upon to make to the insatiate craving of the holy see for those substantial augmentations, that costly support, that burdensome protection, to which he was held to have pledged himself. Such an understanding could last no longer than while either or both parties were actuated rather by religious than by merely selfish motives. The views of Pope Adrian had nothing of a properly religious character in them; his correspondence is but an echo of the one shrill cry for “more.” “Give, grant, endow, restore, and the blessed Peter shall surely send you victory and prosperity.” This is the burden of the papal addresses from the birth to the consummation of the alliance. A certain coincidence of interests, supported upon the religious and loyal character of Charlemagne, had hitherto cemented the union; but, though the result might be overlooked, it is clear that as soon as those interests should diverge or cease to exist, there remained nothing behind to prevent them from falling into irreconcilable opposition. Even within this period of apparent concord and cordiality some symptoms of such a divergency may be detected.
[786-795 A.D.]
In the year 786 Charlemagne paid a fourth visit to Rome; and after performing the customary devotional exercises at the principal shrines and churches, he applied himself to the task of reducing the refractory duke of Benevento to obedience. An accommodation was easily accomplished; Charlemagne accepted the renewed oaths of allegiance of the duke and his vassals, and carried away with him Grimwald (Grimoald), the second son of Arichis (Arighis), as a pledge for the future obedience of the duke and his subjects. No notice was taken of the papal claim upon the territory of Benevento; and Pope Adrian once more saw his royal patron depart without obtaining the object nearest to his heart. During the remainder of his pontificate we trace no further attempt on the part of the pope to realise his favourite project of aggrandisement. The momentary coolness which had followed the defeat of the Calabrian Greeks produced no real estrangement between him and his great patron; and Adrian died (795) in the full enjoyment of the confidence and esteem of Charlemagne.
THE REALM OF THE POPES
At the close of the reign of Charlemagne the possessions of the church of Rome may thus be identified with existing geographical divisions: (1) In virtue of right, or pretension of right, originating prior to the donation of Pepin, the pontiffs exercised temporal jurisdiction over the city and duchy of Rome as it had existed under the Byzantine supremacy, comprehending, as nearly as may now be ascertained, the modern district emphatically known by the name of the “Patrimony Proper,” together with the greatest portion if not the whole of the Campagna di Roma as far south as Terracina. (2) By the donations of Pepin and Charlemagne the church of Rome had reduced into possession the city and exarchate of Ravenna, comprising the modern legations of Bologna, Romagna, Urbino, and Ferrara, with the duchies of Parma and Modena and a portion of the Venetian terra-firma on the mouths of the Po.
