But Pope Innocent III.

had lately released King John from his oath in respect of Magna Charta, and had excommunicated the insurgent barons; and he now instructed his legate to oppose the projected design, with a threat of excommunicating the King of France.

Philip Augustus, who in his youth had dreamed of resuscitating the empire of Charlemagne, was strongly tempted to seize the opportunity of doing over again the work of William the Conqueror; but he hesitated to endanger his power and his kingdom in such a war against King John and the pope.

The prince was urgent in entreating his father: "Sir," said he, "I am your liegeman for the fief you have given me on this side of the sea; but it pertains not to you to decide aught as to the kingdom of England; I do beseech you to place no obstacle in the way of my departure." The king, "seeing his son's firm resolution and anxiety," says the historian Matthew Paris, "was one with him in feeling and desire; but, foreseeing the dangers of events to come, he did not give his public consent, and, without any expression of wish or counsel, permitted him to go, with the gift of his blessing." It was the young and ambitious Princess Blanche of Castille, wife of Prince Louis, and destined to be the mother of St.Louis, who, after her husband's departure for England, made it her business to raise troops for him and to send him means of sustaining the war.

Events justified the discreet reserve of Philip Augustus; for John Lackland, after having suffered one reverse previously, died on the 19th of October, 1216; his death broke up the party of the insurgent barons; and his son, Henry III., who was crowned on the 28th of October, in Gloucester cathedral, immediately confirmed the Great Charter.
