Abstract

The jurisprudence of the law of nature and nations of the Early-Modern Age holds pride of place in the modern historiography of international law. Whereas the classical writers of that age undeniably exercised a significant influence on 19th-century international law, their utility as a historical source for the study of the law of nations from their own period has been far overrated. The development of the law of nations between 1500 and 1800 was much more informed by State practice than historians have commonly credited.

Moreover, historiography overestimates the novelty of the contribution of early-modern jurisprudence and has almost negated its major historic source of inspiration: the late-medieval jurisprudence of canon and Roman law. It is important to restore medieval jurisprudence to its rightful place in the grand narrative of the evolution of international law in Europe. Doing this renders a deeper insight into the dynamics of the jurisprudence of the Early-Modern Age. It shows that natural law acted as a vessel to recycle many of the doctrines of medieval jurisprudence into the language of the early-modern law of nations. But it also shows how it was an altogether feeble attempt at replacing the restrictive authority of scholastic jurisprudence with that of natural justice. As long as the fear of God gave teeth to the precepts of natural justice, it retained some real impact. But one this was lost and 19th-century international lawyers cut the historic bonds between natural law and religion, they pushed it to the wayside and ostracised it altogether from their world.
