The truth of this was soon apparent. Innocent demanded the restoration of all Frederick's conquests in the States of the Church in return for peace; and although nothing was said about the time of the removal of the excommunication, Frederick accepted the terms. But when Frederick saw that there was no intention of absolving him, he refused to surrender the papal cities and thereby technically broke the treaty. Innocent intended to get a treaty which would carry an acknowledgment of the Emperor's failure, and then to reduce him to submission by a council held outside Italy. Negotiations continued until Innocent fled to Lyons, a practically independent city. France, England and Aragon, however, declined to receive him, and Innocent exclaimed that he must come to terms with the Emperor, "for when the dragon has been crushed or pacified, the little serpents will be quickly trodden underfoot."
[Sidenote: First Council of Lyons.]
At Lyons there met in 1245 the General Council to which Frederick had appealed, and which is reckoned by the Romans as the thirteenth of the OEcumenical Assemblies of the Church; 140 archbishops and bishops, besides numerous lesser clergy, were present. Frederick was represented by a celebrated jurist, Thaddeus of Suessa, who pleaded the Emperor's cause. Several points were proposed for settlement; but all other matters were brushed aside, and Innocent hurried on the third and last session of the Council in which Frederick was declared deposed, his subjects were released from their allegiance, the German princes told to elect another King, and Sicily kept for disposal by the Pope in consultation with the Cardinals. All remonstrances were unavailing; even Louis IX quite failed to move the Pope. Frederick realised that it was a fight to a finish, and in a protest he called upon the other princes of the West to help him in depriving the clergy of the wealth which had choked their spiritual power. But this was interpreted as a design for the destruction of the Church, and despite the testimonies to Frederick's orthodoxy published by the Archbishop of Palermo, the papal charge of heresy against him gained wide belief. Innocent in his reply asserted among other things that the Pope was the Legate of Christ who had entrusted him with full powers to act as judge over the earth, and that the Emperor should take an oath of subjection to the Pope who, as overlord, gave him his title and crown. Thus the claims now made on behalf of the Papacy left no room for a belief in the balance of spiritual and secular authority.

Both sides resorted to every kind of expedient. Frederick, aiming especially at the friars, ordered that any who spread or even received the papal letters of condemnation against him should be burnt! Innocent declared an actual crusade against Frederick, stirred up revolt in Sicily, and at length succeeded in raising a rival King in Germany. Henry Raspe, Landgrave of Thuringia, owed his election (1246) almost exclusively to the great prelates of the Rhine; but he died the next year and, although another King was put forward in the person of William Count of Holland, a young man of twenty, he made no progress so long as Frederick lived. Moreover, in Italy Frederick's cause was gaining ground, until the revolt of Parma and the failure of his efforts to retake it ended in the complete rout of his forces (1248). In 1250 Frederick himself died directing by his will that all the rights of the Church should be restored in so far as they did not conflict with the claims of the Empire, provided that the Church herself should recognise the imperial rights. Almost to the last Frederick had been quite willing to be reconciled to the Church, and he died unsubdued. But the Papacy was fighting for that supremacy which experience had shown to be the condition of its existence. Not that any Emperor ever cherished the thought of destroying the Papacy any more than the Pope dreamed of annihilating the Empire. Many passages have been cited to prove that Frederick contemplated the establishment of a Church of his own in Sicily. Here perhaps he did not aim at anything more than Henry VIII afterwards accomplished in England or the barons under Louis IX, as we have seen, threatened on one occasion in France. The language used by his followers was extravagant, even blasphemous, and he did not discourage it. How far he ever aimed as setting himself up as Pope is more doubtful. But in any case, and however much we may be inclined to sympathise with him, it must be allowed that there was abundant reason for the hostility of the Pope.

And the reasons which caused the Papacy to hound Frederick to death, also determined it not to rest until it had exterminated the whole "viper's brood." Innocent IV expressed the most indecent joy at Frederick's death, and refused all offers of peace from his son and successor, Conrad IV. But being too weak to wrest Sicily from the Hohenstaufen he sought for some prince who would accept it as a papal fief. It was refused on behalf of Louis IX's brother, Charles of Anjou, and also by Henry III's brother, Richard Earl of Cornwall, who said that the Pope might as well offer him the moon. Henry III, however, accepted it for his second son Edmund, Earl of Lancaster, a boy of eight, promising to pay the expenses of the conquest. The Pope's action was utterly unscrupulous. In May, 1254, Conrad died in the twenty-sixth year of his age, and the only legitimate Hohenstaufen representative who remained, was his son, distinguished as Conradin, who was under the guardianship of Berthold Marquis of Hohenburg. Conrad's Regent in Italy had been his half-brother Manfred, the son of Frederick by an Italian lady, and the most brilliant of all Frederick's children. Berthold, alarmed at the difficulties, made way for Manfred, who found Innocent ready to come to terms. To Manfred was confirmed the principality of Tarento originally the gift of his father, and he was recognised as Papal Vicar for the greater part of the Sicilian kingdom. But the grant of Sicily was confirmed to Edmund of Lancaster, and the Pope determined to take possession of the kingdom in person. Manfred, now a vassal of the Church, held the bridle of the Pope's horse as he entered his new dominions. But Manfred soon found that the Pope's object was to reduce him to harmlessness and then to get rid of him. He therefore raised the standard of revolt and defeated the papal forces (December, 1254).
[Sidenote: Alexander IV (1254-61).]
At this juncture Innocent IV died at Naples. Matthew Paris relates the dream of a Cardinal who saw the Church accusing the Pope before the throne of God because he had enslaved the Church, had made her a table of money-changers and had shaken faith, abolished justice, and obscured truth. However necessary to the independence of the Papacy was this strenuous struggle, the utterly unscrupulous means employed and the almost complete identification of its spiritual power with its temporal interests is impossible to justify or even to excuse. The new Pope, Alexander IV, a nephew of Gregory IX, without Innocent's ability tried to follow the policy of his predecessor. In 1255 he ratified the grant of Sicily to the young English prince on severe conditions. Indeed, he surpassed his predecessors in the demands made on Henry III and the English Church; until in 1258 his claim for the repayment of the money which he alleged to have been expended in the prosecution of Edmund's cause, brought on a grave constitutional crisis in England and reduced Henry III to impotence.
