In order to present a general outline of the wars of Charles, we have been compelled more than once to pass beyond the crucial and culminating event of his career, his coronation as Emperor at Rome in the year 800, thirty-two years after he had become King of the Franks. All of his conquests are closely related with this elevation to a dignity revered for its venerable traditions, and yet the conquests alone were not in themselves sufficient to secure such an elevation. The acquisition of the imperial title was the result of a revolution, a change of policy, due as much to the intangible forces that move society as to the concrete details of the career of the Conqueror. Master of Italy as he was after the downfall of Lombard powers, this territorial control simply gave Charles the position once held by another great German prince, Theodoric the Ostrogoth. But Theodoric was not an orthodox churchman as Charles was. It was, therefore, the combination of the orthodox religion, which Charles inherited as the successor of the first Frankish kings, and his sway over the Italian peninsula which prepared the way for the great event of Christmas Day, 800, when he took his place in the line of rulers marked by the names of Augustus, Constantine, and Justinian. Although close relations subsisted between the Papal territories in Italy and the Frankish overlord across the Alps, there was, nevertheless, in Rome a considerable degree of autonomy. Charles had no thought of exercising the rights of a sovereign on the basis of the title of Patrician, which he had inherited from his father, and on which he had acted when it came to a question of putting an end finally to Lombard autonomy. But it was only at such crises that the need of intervention was felt, and, as we have seen in the case of Pope Stephen, it was the policy of the Holy See to make use of the Frankish King when questions involving the dignity of the Pope could be settled in no other way. This policy was maintained by Stephen’s successors, but it was not easy to induce Charles to undertake to handle thorny problems which involved the position of the Pope in his own city. There was no Frankish occupation of Rome, foreshadowing the condition of affairs there when another Emperor of the Franks protected the Pope from being overthrown by his unwilling subjects through the use of French bayonets. Rome, like other Italian cities, was often in a state of turbulence owing to factional divisions among its citizens. There was already a beginning of that rivalry among Roman families to secure the Papal throne to one of its members that so often brought degradation to the Papacy during the course of the Middle Ages. Upon the death of Pope Hadrian in 795, after a long pontificate of twenty-three years, Leo III became his successor, but it seems that the succession was not altogether satisfactory to the kinsmen of the dead Pope, for they soon proceeded to extreme measures against his
