Hugo Grotius’s De iure belli ac pacis: a Report on the Worldwide Census of the First Edition (1625)

This article provides new information on the publication history of the first edition of the text that, according to many scholars, laid the ground for the growth of international law: Hugo Grotius’s De iure belli ac pacis. Drawing on the preliminary findings of the Grotius Census Project at the Max Planck Institute for Comparative Public Law and International Law, funded by the German Research Foundation (Deutsche Forschungsgemeinschaft), the following pages shed light on the first three states of the typescript, the sources that Grotius had access to in France while drafting the book, and the early circulation of the 1625 edition, published by Nicolas Buon in Paris. The goal of this publication is to disseminate updated information on the printing history of this key text in the history of legal and political thought, and to invite readers to come forward with more information about the location of the remaining copies of the text, in order to advance our understanding of the rise of international law around the world.
