The following announcement on the acquisition of Grotius’ De iure Belli ac Pacis was posted today on the website of the Peace Palace Library:

The Peace Palace Library has acquired a unique first print of the first edition of “De iure belli ac pacis libri tres” by Hugo Grotius […] at an auction in Hamburg yesterday evening. It is a very valuable addition to the famous Grotius-Collection of the Library.

Grotius wrote this book in 1625 during his exile in Paris. In this work, based on natural law, he investigated and explained his theory of “just war” (when war is justified, what are the causes of war and what are the rules of war). It is widely regarded as the “Foundation of Modern International Law”. The book was finished in great haste to be in time for the Frankfurt Bookfair. As a result there had not been enough time to correct all pages and page numbering. This print also lacks indices and a table of content. For specialists it will be most interesting to compare this print with later corrected versions.

The only other known copy of this print is in the Bodleian Library in Oxford.

After 385 years Grotius’ masterpiece has come to The Hague, the “Legal Capital of the World”. The acquisition of this book by the Library will stimulate further Grotius-research and the study of modern international law.

The acquisition of this great work has been made possible with the support of:

• Dorus Rijkers Fonds;
• Samenwerkende Maritieme Fondsen;
• Dr. Hendrik Muller’s Vaderlandsch Fonds;
• M.A.O.C. Gravin van Bylandt Stichting;
• BRILL Publishers;
• Prof. Mr. Laurens Winkel;
• and the Carnegie-Foundation.
