The question of the succession was the main thing which occupied the mind of the king and the whole nation in Henry's later years. It had a real interest for every man in an age when any doubt as to the heir meant the outbreak of civil war such as had occurred at the death of the Conqueror and of Rufus. There was now a problem of some difficulty to be solved. Henry's only son William had been drowned at sea in 1120. He had no other child born in wedlock save a daughter, Matilda, who married the emperor Henry V., but had no issue by him. On the emperor's decease she wedded as her second husband Geoffrey of Anjou (1127), to whom during her father's last years she bore two sons. But the succession of a woman to the crown was as unfamiliar to English as to Norman ideas, nor did it seem natural to either to place a young child on the throne. Moreover, Matilda's husband Geoffrey was unpopular among the Normans; the Angevins had been the chief enemies of the duchy for several generations, and the idea that one of them might become its practical ruler was deeply resented. The old king, as was but natural, had determined that his daughter should be his successor; he made the great council do homage to her in 1126, and always kept her before the eyes of his people as his destined heir. But though he had forced or cajoled every leading man in England and Normandy to take his oath to serve her, he must have been conscious that there was a large chance that such pledges would be forgotten at his death. The prejudice against a female heir was strong, and there were too many turbulent magnates to whom the anarchy that would follow a disputed succession presented temptations which could not be resisted.
Henry died suddenly on the 25th of November 1135, while he was on a visit to his duchy of Normandy. The moment that his death was reported the futility of oaths became apparent. A majority of the Norman barons appealed to Theobald, count of Blois, son of the Conqueror's daughter Adela, to be their duke, and to save them from the yoke of the hated Angevin. His supporters and those of Matilda were soon at blows all along the frontier of Normandy. Meanwhile in England another pretender had appeared. Stephen, count of Boulogne, the younger brother of Theobald, had landed at Dover within a few days of Henry's death, determined to make a snatch at the crown, though he had been one of the first who had taken the oath to his cousin a few years before. The citizens of London welcomed him, but he was not secure of his success till by a swift swoop on Winchester he obtained possession of the royal treasure--an all-important factor in a crisis, as Henry I. had shown in 1100. At Winchester he was acknowledged as king by the bishop, his own brother Henry of Blois, and by the great justiciar, Roger, bishop of Salisbury, and the archbishop, William of Corbeil. The allegiance of these prelates was bought by an unwise promise to grant all the demands of the church party, which his predecessor had denied, or conceded only in part. He would permit free election to all benefices, and free legislation by ecclesiastical synods, and would surrender any claims of the royal courts to have jurisdiction over clerks or the property of clerks. It then remained necessary to buy the baronage, of which only a few members had as yet committed themselves to his side. It was done by grants of lands and privileges, the first instalment of a never-ending crop of ruinous concessions which Stephen continued to make from the day of his accession down to the day of his death.
