Customary law governed most European societies during the Middle Ages and early modern period. To better understand the roots of legal customs and their implications for long-run development, we introduce an atlas of customary regions of Ancien Régime France. We also describe the historical origins of French customs, their role as a source of law, and their legal content. We then offer some insights into the research possibilities opened by this database.
