Rome, who had set her foot on the neck of a king, was destined under one of the sons of Henry II to set it on the neck of England. John being unwilling to acknowledge an archbishop of Canterbury illegally nominated by Pope Innocent III, the latter, more daring than Hildebrand, laid the kingdom under an interdict. Upon this John ordered all the prelates and abbots to leave England, and sent a monk to Spain as ambassador to Mahomet-el-Nasir, offering to turn Mahometan and to become his vassal. But as Philip Augustus was preparing to dethrone him, John made up his mind to become a vassal of Innocent, and not of Mahomet--which was about the same thing to him. On the 15th May 1213, he laid his crown at the legate's feet, declared that he surrendered his kingdom of England to the pope, and made oath to him as to his lord paramount.[132] [132] Resignavit coronam suam in manus domini papæ. Matth. Paris, 198 et 207. A national protest then boldly claimed the ancient liberties of the people. Forty-five barons armed in complete mail, and mounted on their noble war-horses, surrounded by their knights and servants and about two thousand soldiers, met at Brackley during the festival of Easter in 1215, and sent a deputation to Oxford, where the court then resided. "Here," said they to the king, "is the charter which consecrates the liberties confirmed by Henry II, and which you also have solemnly sworn to observe."... "Why do they not demand my crown also?" said the king in a furious passion, and then with an oath,[133] he added: "I will not grant them liberties which will make me a slave." This is the usual language of weak and absolute kings. Neither would the nation submit to be enslaved. The barons occupied London, and on the 15th June 1215, the king signed the famous _Magna Charta_ at Runnymede. The political protestantism of the thirteenth century would have done but little, however, for the greatness of the nation, without the religious protestantism of the sixteenth. [133] Cum juramento furibunds. Ibid. 213. [Sidenote: POPERY AND LIBERTY IN COLLISION.] This was the first time that the papacy came into collision with modern liberty. It shuddered in alarm, and the shock was violent. Innocent swore (as was his custom), and then declared the Great Charter null and void, forbade the king under pain of anathema to respect the liberties which he had confirmed,[134] ascribed the conduct of the barons to the instigation of Satan, and ordered them to make apology to the king, and to send a deputation to Rome to learn from the mouth of the pope himself what should be the government of England. This was the way in which the papacy welcomed the first manifestations of liberty among the nations, and made known the model system under which it claimed to govern the whole world. [134] Sub intimatione anathematis prohibentes ne dictus rex eam observare præsumat. Matth. Paris, 224.
