A detailed historical study focuses on the career of a prominent earl to illuminate the feudal ambition and lawlessness of the Anarchy, relying chiefly on surviving charters as documentary spine. It reconstructs his policies and conflicts, situating them within wider political and institutional questions such as succession claims to the crown, the origin and character of earldoms, fiscal and administrative development, and urban governance. The author scrutinizes episodes including an empress's appeal to Rome and a proposed coronation, an obscure Oxford intrigue, and the implications of castle-building, and supplements the narrative with genealogical research, charter analysis, and an essay on the creation of a neighbouring earldom.
