Henry's conciliatory measures were not taken a moment too soon. He had but just time to announce his good intentions, and to give some earnest of his desire to carry them out, when he found himself involved in a desperate civil war. The barons had broken loose, headed by Robert of Belesme, the turbulent Earl of Shrewsbury, and they were set on making Duke Robert King of England. Robert, indeed, had just returned from Palestine, and had retaken possession of his duchy shortly after his brother's death. He planned an invasion of England to assist his partisans, and began to collect an army. But the new king was too much for his shiftless brother. When Robert landed at Portsmouth, he bought him off for a moment by offering him a tribute of £3000, an irresistible bribe to the impecunious duke, and then used his opportunity to crush the rebellious barons. The fate of the rising was settled by the next summer. Gathering together the English shire levies and those of the baronage who were faithful to him, the king marched against Robert of Belesme and his associates. The successful sieges of Arundel and Bridgenorth decided the war: Robert was forced to surrender, and granted his life on condition of forfeiting his estates and leaving the realm. "Rejoice, King Henry, for now may you truly say that you are lord of England," cried the English levies to their monarch, "since you have put down Robert of Belesme, and driven him out of the bounds of your kingdom" (1101). [Sidenote: =Marriage of Henry to Matilda of Scotland.=] So Henry retained the crown that he had seized, and set to work to strengthen his position in the land. He did his best to conciliate the native English by marrying, five months after his accession, a princess of the old royal house of King Alfred. The lady was Eadgyth, or Matilda as the Normans re-named her, the daughter of Malcolm, the King of Scotland and of Margaret, the sister of Eadgar the Etheling. So the issue of King Henry, and all his descendants who sat on the English throne, had the blood of the ancient kings of Wessex in their veins. Some of the Normans mocked at this marriage, and at the anxiety which Henry showed to please his native-born subjects, and nicknamed him "Godric," an English name which sounded uncouth to their own ears. But the king heeded not, when he got so much solid advantage from his conduct, and the prosperity of his reign justified his wisdom. [Sidenote: =Fusion of English and Norman races.=]
