The Law of Nations: Or, Principles of the Law of Nature, Applied to the Conduct and Affairs of Nations and Sovereigns

This enormously influential work by Swiss diplomat and jurist Emmerich de Vattel (1714–76) was first published in 1758, and is credited with shaping modern international law by applying natural law to international relations. Its argument for liberty and equality proved influential upon the American Declaration of Independence, with Benjamin Franklin commenting on its usefulness to the drafters. The book was translated into English in 1760, 1787, and 1797: the latter version was revised by Joseph Chitty the elder (1775–1841), a barrister and one of the most prolific legal writers of his day, who published more than twenty books on law in his lifetime, and also served as tutor or mentor to some of the most influential lawyers of nineteenth-century England. First published in 1834, Chitty's version amends the errors of the anonymous 1797 translation, as well as revising and expanding the explanatory notes.
