Rome, which he had not seen for nearly eleven years, would no longer shut her gates against the pope. Welcomed by senate and people, he made his public entrance into the Lateran in March A.D. 1178, where in the following year he gathered together 300 bishops in the =Third Lateran Council= (the 11th œcumenical), in order by their advice to heal the wounds which the schism of the church had made. Here also, in order to prevent double elections in time to come, it was resolved that for a valid papal election two-thirds of the whole college of cardinals must be agreed. The right of concurrence assigned by the decree of Nicholas II. in A.D. 1059 to the people and emperor was treated as antiquated and forgotten, and was not even alluded to. § 96.16. Even before his victory over the powerful Hohenstaufen, Alexander III. during his exile won a yet more brilliant success in England. King Henry II., A.D. 1154-1189, wished to establish again the supremacy of the state over church and clergy, and thought that he would have a pliant tool in carrying out his plans in =Thomas à Becket=, whom he made archbishop of Canterbury, in A.D. 1162. But as primate of the English church, Thomas proved a vigorous upholder of hierarchical principles. Instead of the accommodating courtier, the king found the archbishop immediately upon his consecration the bold asserter of the claims of the church. The jovial man of the world became at once the saintly ascetic. At a council at Tours in A.D. 1163, he returned into the pope’s own hand the pallium with which an English prince had invested him in name of the king, resigning also his archiepiscopal dignity, that he might receive these directly as a papal gift. Straightway began the conflict between the king and his former favourite. Henry summoned a diet at Clarendon, where he obtained the approval of the superior clergy for his anti-hierarchical propositions; Thomas also for a time withstood, promising at last, when urged on all sides, to assent to the constitutions, but refusing to sign the document when it was placed before him. The king now ordered a process of deposition to be executed against him, and Thomas then fled to France, where the pope was at that time residing. The pope released him from his promise, condemned the Constitutions of Clarendon, and threatened the king with anathema and interdict. At last, after protracted negotiations, in A.D. 1170 by means of a personal interview on the frontiers of Normandy, a reconciliation was effected; by which, however, neither the king nor the archbishop renounced their claims. Thomas now returned to England and threatened with excommunication all bishops who should agree to the Constitutions of Clarendon. Four knights seized upon an unguarded word of the king which he had uttered in passion, and murdered the archbishop at the altar in A.D. 1170. Alexander
