Henry II created the common law in the twelfth century, which resulted in revolutionary changes in the English legal system, chief among which were the action of debt, the assize of novel disseisin, and trial by jury.
The sources of these three institutions have long been ascribed to influences from other legal systems such as Roman law.
Professor Makdisi has uncovered new evidence which suggests that these institutions may trace their origins directly to Islamic legal institutions.
This Article explores the origins of these three institutions by tracing their unique characteristics to three analogous institutions in Islamic law.
The royal English contract protected by the action of debt is identified with the Islamic 'Aqd, the English assize of novel disseisin is identified with the Islamic Istihqaq, and the English jury is identified with the Islamic Lafif.
The evidence lies in the unique identity of characteristics of these three institutions with those of their Islamic counterparts, the similarity of function and structure between Islamic and common law, and the historic opportunity for transplants from Islam through Sicily.
The origins of the common law are shrouded in mystery. Created over seven centuries ago during the reign of King Henry II of England; to this day we do not know how some of its most distinctive institutions arose.1
For example, where did we get the idea that contract transfers property ownership by words and not by delivery or that possession is a form of property ownership? Even more importantly, where did we get the idea that every person is entitled to trial by jury?
Historians have suggested that the common law is a product of many different influences, the most important being the civil law tradition of Roman and canon law.2
Yet, as we shall see, the legal institutions of the common law fit within a structural and functional pattern that is unique among western legal systems and certainly different from that of the civil law. The coherence of this pattern strongly suggests the dominating influence of a single preexisting legal tradition rather than a patchwork of influences from multiple legal systems overlaid on a Roman fabric. The only problem is that no one preexisting legal tradition has yet been found to fit the picture.
This Article looks beyond the borders of Europe and proposes that the origins of the common law may be found in Islamic Law.
