Hugo Grotius’s De iure belli ac pacis: A Report on the Worldwide Census of the 1650 Edition

This note studies the 1650 edition of Hugo Grotius’s De iure belli ac pacis. Using online and card catalogues, we have located eighty-nine copies, thirty-seven of which we examined in person, with an additional six fully digitised copies online. We hope that this research note on the preliminary results will generate greater interest in this unduly neglected edition. The note shows how, despite the connection established in the history of seventeenth-century politics that emphasized the ties between Grotius and the Peace of Westphalia, the reception of Grotius’s 1650 edition bore no relation to the debates at Osnabrück and Münster. However, this is an influential edition, cherished by collectors and authors. According to our findings, it would be reproduced in a number of later reprints.
