At the coronation of Innocent III the officiating priest had used these words: ‘Take the tiara and know that thou art the father of princes and kings, the ruler of the world, the Vicar on earth of our Saviour Jesus Christ.’ To Lothario di Conti this utterance was but the confirmation of his own beliefs, as unshakable as those of Hildebrand, as wide in their scope as the imperialism of Frederick Barbarossa or Henry VI. ‘The Lord Jesus Christ,’ he declared, ‘has set up one ruler over all things as His Universal Vicar, and as all things in Heaven, Earth, and Hell bow the knee to Christ, so should all obey Christ’s Vicar that there be one flock and one shepherd.’ Again: ‘Princes have power on earth, priests have also power in Heaven.’
In illustration of these views he likened the Papacy to the sun, the Empire to the lesser light of the moon, and recalled how Christ in the Garden of Gethsemane gave to St. Peter two swords. By these, he explained, were meant temporal and spiritual power, and emperors who claimed to exercise the former could only do so by the gracious consent of St. Peter’s successors, since ‘the Lord gave Peter the rule not only of the universal Church but also the rule of the whole world’.
Gregory VII had made men wonder in the triumph of Canossa whether such an ideal of the Papacy could ever be realized; but as if in proof he had been hunted from Rome and died in exile. It was left to Innocent III to exhibit the partial fulfilment, at any rate, of all that his predecessor had dreamed. In character no saintly Bernard of Clairvaux, but a clear-brained practical statesman, he set before himself the vision of a kingdom of God on earth after the pattern of earthly kingdoms; and to this end, that he sincerely believed carried with it the blessing of God for the perfecting of mankind, he used every weapon in his armoury.
Sometimes his ambitions failed, as when, in a real glow of enthusiasm, he preached the Fourth Crusade—an expedition that ended in Venice, who had promised the necessary ships, diverting the crusaders to storm her a coveted port on the Dalmatian coast, and afterwards to sack and burn Constantinople in the mingled interests of commerce and pillage. His anger at the news that the remonstrances of his legates had been ignored could hardly at first be extinguished. Not thus had been his plan of winning Eastern Christendom to the Catholic Faith and of destroying the infidel; for the Latin Empire of Constantinople, set up by the victorious crusaders, was obviously too weak to maintain for long its tyranny over hostile Greeks, or to serve as an effective barrier against the Turks. Statesmanship, however, prompted him to reap what immediate harvest he could from the blunders of his faithless sons; and he accepted the submission of the Church in Constantinople as a debt long owing to the Holy See.
The Fourth Crusade, in spite of the extension of Rome’s ecclesiastical influence, must be reckoned as one of Innocent’s failures. In the West, on the other hand, the atmosphere created by his personality and statecraft made the name of ‘The Lord Innocent’ one of weight and fear to his enemies, of rejoicing to his friends. When upholding Queen Ingeborg he had stood as a moral force, bending Philip Augustus to his will by his convinced determination; and this same tenacity of belief and purpose, added to the purity of his personal life and the charm of his manner, won him the affection of the Roman populace, usually so hostile to its Vicars.
Mediaeval popes were, as a rule, respected less in Italy than beyond the Alps, and least of all in their own capital, where too many spiritual gifts had been seen debased for material ends, and papal acts were often at variance with pious professions. During the pontificate of Innocent III, however, we find the ‘Prefect’, the imperial representative at Rome, accept investiture at his hands, the ‘Senator’, chief magistrate of the municipality, do him homage; and through this double influence his control became paramount over the city government.
In Naples and Sicily he was able to continue the policy of Constance, drive out rebellious German barons, struggle against the Saracens in Sicily, and develop the education of his ward, the young King of Naples, as the spiritual son who should one day do battle for his ideals. ‘God has not spared the rod,’ he wrote to Frederick II. ‘He has taken away your father and mother: yet he has given you a worthier father, His Vicar; and a better mother, the Church.’
In Lombardy, where the Guelfs naturally turned to him as their champion, the papal way was comparatively smooth, for the cruelty of Barbarossa and his son Henry VI had aroused hatred and suspicion on all sides. Thus Innocent found himself more nearly the master of Italy than any Pope before his time, and from Italy his patronage and alliances extended like a web all over Europe.
Philip Augustus of France, trying to ignore and defy him, found in the end the anger he aroused worth placating: John of England changed his petulant defiance into submission and an oath of homage: Portugal accepted him as her suzerain: rival kings of Hungary sought his arbitration: even distant Armenia sent ambassadors to ask his protection. His most impressive triumph, however, was secured in his dealings with the Empire.
Henry VI had wished, we have seen, to make the imperial crown hereditary; but no German prince would have been willing to accept the child he left as heir to his troubled fortunes. The choice of the electors therefore wavered between another Hohenstaufen, Philip of Suabia, brother of the late Emperor, and the Welf Otto, son of Henry the Lion. The votes were divided, and each claimant afterwards declared himself the legally elected emperor, one with the title Philip II, the other with that of Otto IV.
