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. The pretender was crowned at Westminster on the 22nd of December 1135--less than a month after his uncle's death. No one yet openly withstood him, but he was well aware that his position was precarious, and that the claims of Matilda would be brought forward ere long by the section of the baronage which had not yet got from him all they desired. Meanwhile, however, he was encouraged to persevere by the fact that his brother Theobald had withdrawn his claim to the duchy of Normandy, and retired in his favour. For a space he was to be duke as well as king; but this meant merely that he would have two wars, not one, in hand ere long. Matilda's adherents were already in the field in Normandy; in England their rising was only delayed for a few months. Civil war.
