By 1190, King Richard I of England (1189-1199) had departed for the Third Crusade and had settled on William Longchamp, royal chancellor and bishop of Ely, as the chief justiciar, the king’s regent during the royal absence. But before Richard had even left the European continent, Longchamp’s justiciarship had provoked a powerful reaction from those subjected to it. The hue and cry lifted against the chief justiciar by leaders of the revolt that ousted him included accusations that Longchamp filled England and its offices with “foreigners and unknown men” and that he ruled without the appares, associates whom Richard had included in the regency to assist the chief justiciar. Recent research has shown that the latter charge is patently untrue but the former, utilizing foreigners and others unfamiliar with England and its government, was fundamentally true, at least with regard to justice and the shrievalties. Does Longchamp’s style of management repeat itself with castles and what were the implications for him, the kingdom, and the king? A cursory glance at events during his justiciarship shows that castles played a large role in the narrative, from the massacre of the Jews at York Castle to the arrest of Archbishop Geoffrey at Dover Castle. Though the evidence is of a more tentative nature than that for judicial activity and shrievalties, Longchamp employed in this critical position men close to him, both personal dependents and tested curial servants, a pattern of appointment markedly different from that of the king. Richard I’s practices benefited the baronage, but the chancellor’s determination to bring as many castles as possible under his direct control worked to alienate the chief justiciar from his subjects and disastrously eroded his power base.
