22. Young Henry's Coronation and the Revolt of the Barons. 1172—1174.—In the spring of 1172 Henry was back in Normandy. The English barons were longing to take advantage of his quarrel with the Church, and his only chance of resisting them was to propitiate the Church. He met the Papal legates at Avranches, swore that he was innocent of the death of Thomas, and renounced the Constitutions of Clarendon. He then proceeded to pacify Louis VII., whose daughter was married to the younger Henry, by having the boy recrowned in due form. Young Henry was a foolish lad, and took it into his head that because he had been crowned his father's reign was at an end. In 1173 he fled for support to his father-in-law and persuaded him to take up his cause. "Your master," said Louis to the ambassadors of the father, "is king no longer. Here stands the king of the English." These words were the signal for a general attack on the elder king. Headed by Louis, his neighbours and discontented subjects took arms against him, and it was not till September that he prevailed over them. In July the great English barons of the north and centre rose in insurrection, and William the Lion, king of the Scots, joined them. De Lucy, the Justiciar, stood up for Henry; but, though he gained ground, the war was still raging in the following year, 1174. In the spring of that year the rebels were gaining the upper hand, and the younger Henry was preparing to come to their help. In July the elder Henry landed in England. For the first and only time in his life he brought to England the mercenaries who were paid with the scutage money. At Canterbury he visited the tomb of Thomas, now acknowledged as a martyr, spent the whole night in prayer and tears, and on the next morning was, at his own request, scourged by the monks as a token of his penitence. That night he was awakened by a messenger with good news. Ranulf de Glanvile had won for him a great victory at Alnwick, had dispersed the barons' host, and had taken prisoner the Scottish king. About the same time the fleet which was to bring his son over was dispersed by a storm. Within a few weeks the whole rebellion was at an end. It was the last time that the barons ventured to strive with the king till the time came when they had the people and the Church on their side. William the Lion was carried to Normandy, where, by the treaty of Falaise, he acknowledged himself the vassal of the king of England for the whole of Scotland.

23. The Assize of Arms. 1181.—In September 1174 there was a general peace. In 1181 Henry issued the Assize of Arms, organising the old fyrd in a more serviceable way. Every English freeman was bound by it to find arms of a kind suitable to his property, that he might be ready to defend the realm against rebels or invaders. The Assize of Arms is the strongest possible evidence as to the real nature of Henry's government. He had long ago sent back to the Continent the mercenaries whom he had brought with him in the peril of 1174, and he now entrusted himself not to a paid standing army, but to the whole body of English freemen. He was, in truth, king of the English not merely because he ruled over them, but because they were ready to rally round him in arms against those barons whose ancestors had worked such evil in the days of Stephen. England was not to be given over either to baronial anarchy or to military despotism.
