1712 edition of Hugo Grotius' (1583-1645) groundbreaking work "De Jure Belli ac Pacis Libri Tres" (Three Books on the Law of War and Peace). It is considered his magnum opus. Hugo Grotius' De Jure Belli ac Pacis is widely regarded as the founding work of modern international law and a milestone in the history of civilisation. Written in 1625, it was influenced by the turmoil of the Thirty Years' War (1618–1648) and aimed to systematically describe and regulate the behaviour of nations. This edition also includes Grotius' treatise Differtatio de Mari Libero (Treatise on the Free Sea) as well as notes by the author and Joannes Fridericus Gronovius.
