We have noted the way in which Henry used his children as his tools or as the counters of his game. He began with them very young. His eldest child, William, to whom we have seen homage done immediately after the coronation, died very soon after, and Henry, who was born in February, 1155, and had received conditional homage when he was two months old, now became the heir apparent. The next child was a daughter, Matilda, born in 1156; in 1157 Richard was born, at either Oxford or Woodstock; Geoffrey, the next brother, came in 1158; then Eleanor, in 1162; Johanna, in 1165; and last of all John, in 1167. On Henry’s attempts to provide for these children hangs nearly all the interest of his foreign wars; and the marriages of the daughters form a key to the history of the foreign policy of England and her alliances for many ages. [Sidenote: His projects of marriage for them. ] [Sidenote: Marriage of Henry and Margaret. ] The game may be considered to begin with Richard, who at the age of a year was betrothed to the daughter of Raymond of Barcelona and Queen Petronilla of Aragon. This was done, it appears, to bind the count and queen either to help or to stand neutral in the war of Toulouse. The betrothal came to nothing. Henry, the elder brother, was the next victim. The peace of 1160 assigned him, at the age of five, as husband to the little lady Margaret of France, Lewis’s daughter by his second wife, Constance of Castile. This marriage was not only to seal the peace but to secure to Henry a good frontier between Normandy and France. The castles of Gisors and Neafle, and the county of the Vexin, which lay between Normandy and Paris, were to be Margaret’s portion, not to be surrendered until the marriage could be formally celebrated, and until then to remain in the custody of the Templars. Henry, however, did not stick at trifles. The little Margaret had been put into his hands to learn English or Norman ways. He had the marriage celebrated between the two children, and then prevailed on the Templars to surrender the castles. Lewis never forgave that, and the Vexin quarrel remained an open sore during the rest of the reign; for after the death of the younger Henry his rights were transferred to Richard by another unhappy marriage contract with another of Lewis’s daughters. Practically the question was settled by the betrayal of Gisors to Philip, by Gilbert of Vacœuil, whilst Richard was in Palestine; but the struggle continued until John finally lost not only the Vexin but Normandy itself and all else that he had to lose. For the present, however, the outbreak of war, to which Henry’s sharp practice led, was only a brief one. Henry was successful, and peace was concluded in August, 1161. The year 1162 he spent in Normandy, holding councils and organizing the administration of the duchy, as he had done that of the kingdom in his first year.
