Custom in Late Medieval France
The idea of the dynamic movement of law—diffusion of legal institutions, rules, and culture—is deeply embedded in European legal history since antiquity. All the while, a potent spirit of local custom has sustained national history, forming an equally integral part of Europe’s legal tradition. This chapter examines the sources of law in late medieval France and the doctrine of custom. It also discusses the growth of royal justice and the relationship between private law and political power. An overview of major historiographical debates concerning the theory and nature of custom sheds light on the question as to whether the notion of common law (droit commun) emerged autonomously in France or only after custom was written down on the model of Roman law as jus commune.
