It was in 1173, the year after his return from Ireland and his submission to the papal legates at Avranches, that King Henry became involved in the first of a series of troubles which were to pursue him for the rest of his life--the rebellions of his graceless sons. His wife Eleanor of Aquitaine had borne him many children. Henry, the eldest surviving son, had already been crowned in 1170 as his father's colleague and successor; not only he, but Richard the second, and Geoffrey the third son, were now old enough to chafe against the restraints imposed upon them by an imperious and strong-willed father. The old king very naturally preferred to keep his dominions united under his own immediate government, but he had designated his eldest son as his successor in England and Normandy, while Richard was to have his mother's heritage of Aquitaine, and Geoffrey's wife's dowry, the duchy of Brittany, was due to him, now that he had reached the verge of manhood. The princes were shamelessly eager to enter on their inheritance, the king was loath to understand that by conferring a titular sovereignty on his sons he had given them a sort of right to expect some share of real power. Their grudge against their father was sedulously fostered by their mother Eleanor, a clever and revengeful woman, who could never forgive her husband for keeping her in the background in political matters and insulting her by his frequent amours. Her old subjects in Aquitaine were secretly encouraged by her to follow her son Richard against his father, whom the barons of the south always regarded as an alien and an intruder. The Bretons were equally willing to rise in the name of Geoffrey and Constance against the guardian who was keeping their prince too long waiting for his inheritance. In England the younger Henry had built himself up a party among the more turbulent section of the baronage, who remembered with regret and longing the carnival of licence which their fathers had enjoyed under King Stephen. Secret agreements had also been made with the kings of France and Scotland, who were eager to take advantage of the troubles which were about to break out.
