Conquered England argues that Duke William of Normandy's claim to succeed Edward the Confessor on the throne of England profoundly influenced not only the practice of royal succession, but also played a large part in creating a novel structure of land tenure, dependent on the king. In thesetwo fundamental respects, the attempt made in the aftermath of the Conquest to demonstrate seamless continuity with Anglo-Saxon England severed almost all continuity. A paradoxical result was a society in which instability in succession at the top exacerbated instability lower down. The firstserious attempt to address these problems began when arrangements were made, in 1153, for the succession to King Stephen. Henry II duly succeeded him, but claimed rather to have succeeded his grandfather, Henry I, Stephen's predecessor. Henry II's attempts to demonstrate continuity with hisgrandfather were modelled on William the Conqueror's treatment of Edward the Confessor. Just as William's fabricated history had been the foundation for the tenurial settlement recorded in the Domesday Book, so Henry II's, in a different way, underpinned the early common law procedures which beganto undermine aspects of that settlement. The official history of the Conquest played a crucial role not only in creating a new society, but in the development of that society.
