mother's inheritance of Ponthieu, had left directions with the vassals of Bellême for its defence, but the campaign was a short one. Henry, assisted by his new vassal, the Count of Anjou, and by his nephew, Theobald of Blois, speedily reduced city and lordship to submission. Orderic Vitalis, who was living in Normandy at this time, in the monastery of St. Evroul, declares that following this peace, made in the spring of 1113, for five years, Henry governed his kingdom and his duchy on the two sides of the sea with great tranquillity. These years, to the great insurrection of the Norman barons in 1118, were not entirely undisturbed, but as compared with the period which goes before, or with that which follows, they deserve the historian's description. One great army was led into Wales in 1114, and the Welsh princes were forced to renew their submission. Henry was apparently interested in the slow incorporation of Wales in England which was going forward, but prudently recognized the difficulties of attempting to hasten the process by violence. He was ready to use the Church, that frequent medieval engine of conquest, and attempted with success, both before this date and later, to introduce English bishops into old Welsh sees. From the early part of this reign also dates the great Flemish settlement in Pembrokeshire, which was of momentous influence on all that part of Wales. These years were also fully occupied with controversies in the Church, whose importance for the state Henry clearly recognized. Out of the conflict over investitures, regarded from the practical side, the Norman monarchy had emerged, as we have seen, in triumph, making but one slight concession, and that largely a matter of form. From the struggle with the empire on the same issue, which was at this date still unsettled, the Church was destined to gain but little more, perhaps an added point of form, depending for its real value on the spirit with which the final agreement was administered. In the matter of investitures, the Church could claim but little more than a drawn battle on any field; and yet, in that great conflict with the monarchies of Europe into which the papacy had been led by the genius of Hildebrand, it had gained a real and great victory in all that was of the most vital importance. The pope was no longer the creature and servant of the emperor; he was not even a bishop of the empire. In the estimation of all Christendom, he occupied an equal throne, exercised a co-ordinate power, and appeared even more directly as the representative of the divine government of the world. Under his rule was an empire far more extensive than that which the emperor controlled, coming now to be closely centralized with all the machinery of government, legal, judicial, and administrative, highly organized and pervaded from the highest to the lowest ranks with a uniform theory of the absolute right of the ruler and of the duty of unquestioning
