Hugo Grotius’s De iure belli ac pacis: A Report on the Worldwide Census of the Third Edition (1631)

Abstract

Hugo Grotius’s best-known work, De iure belli ac pacis, appeared in 1625 in Paris with the author’s approval. A second unauthorised version was published in 1626 in Frankfurt. In 1631 the Amsterdam publisher, Willem Janszoon Blaeu (1571–1638), issued the third edition, this one authorised by the author – and this edition featured nearly a thousand revisions by Grotius. The purpose of this report is to analyse the context behind the publication of this third edition and the copies’ provenance records. Using online and card catalogues, we have located 154 copies. We examined 52 copies in person, and another three fully digitised copies online. We hope that this research note on preliminary results will generate greater interest in this unduly neglected edition, and that readers will kindly bring further copies to our attention.
