Conflict is defined here broadly and inclusively as an element of social life and social relations. Its study encompasses the law, not just disputes concerning property, but wider issues of criminality, coercion and violence, status, sex, sexuality and gender, as well as the phases and manifestations of conflict and the behaviors brought to bear on it. It engages, too, with the nature of the transformation spanning the Carolingian period, and its implications for the meanings of power, violence, and peace. Conflict in Medieval Europe represents the 'American school' of the study of medieval conflict and social order. Framed by two substantial historiographical and conceptual surveys of the field, it brings together two generations of scholars: the pioneers, who continue to expand the research agenda; and younger colleagues, who represent the best emerging work on this subject. The book therefore both marks the trajectory of conflict studies in the United States and presents a set of original, highly individual contributions across a shifting conceptual range, indicative of a major transition in the field.
