An income suitable for his position had now certainly been secured for the king's youngest son, for in addition to the Gloucester inheritance that of another of the sons of Henry I, Reginald, Earl of Cornwall who had died in 1175, leaving only daughters, was held by Henry for his use, and still earlier the earldom of Nottingham had been assigned him. At this time, however, or very soon after, a new plan suggested itself to his father for conferring upon him a rank and authority proportionate to his brothers'. Ireland was giving more and more promise of shaping itself before long into a fairly well-organized feudal state. If it seems to us a turbulent realm, where a central authority was likely to secure little obedience, we must remember that this was still the twelfth century, the height of the feudal age, and that to the ruler of Aquitaine Ireland might seem to be progressing more rapidly to a condition of what passed as settled order than to us. Since his visit to the island, Henry had kept a close watch on the doings of his Norman vassals there and had held them under a firm hand. During the rebellion of 1173 he had had no trouble from them. Indeed, they had served him faithfully in that struggle and had been rewarded for their fidelity. In the interval since the close of the war some advance in the Norman occupation had been made. There seemed to be a prospect that both the south-west and the north-east--the southern coast of Munster and the eastern coast of Ulster--might be acquired. Limerick had been temporarily occupied, and it was hoped to gain it permanently. Even Connaught had been successfully invaded. Possibly it was the hope of securing himself against attacks of this sort which he may have foreseen that led Roderick of Connaught to acknowledge himself Henry's vassal by formal treaty. If he had any expectation of this sort, he was disappointed; for the invaders of Ireland paid no attention to the new relationship, nor did Henry himself any longer than suited his purpose.
