In this new approach to the history of medieval kings, Andrew W. Lewis views French royal succession not within the traditional “constitutional” framework, but in terms of family strategy and the relation of the family to the tenure of office and lands. For the succession involved not only the devolution of the crown to the eldest son, but the fate of the entire family group and its possessions. Thus Lewis takes into account the family's view of itself, the provisions made for cadet sons and for daughters, the nature of their property rights, the bonds and obligations within the family group, and contemporary notions of kingship and kingdom. Within this context, motives and behavior that previously seemed idiosyncratic are now clear. The cumulative effect significantly alters the traditional conception of the Capetian monarchy and thus illuminates a central aspect of medieval French history.
