"Emmerich de Vattels’ 1758 Law of Nations was on George Washington’s desk on the first day of his presidency. Law of Nations was also used and quoted from extensively by the Founders and Framers of the United States Constitution, including Benjamin Franklin. Law of Nations was cited more frequently than other Treatises on International Law in early American Court Cases, and historically was the primary textbook used by American Universities on matters of Natural Law, and Natural Rights."
