The Law of Nations is the supreme work on international law throughout the Revolutionary and Napoleonic eras. I thoroughly enjoy reading Vattel in a greater way than I enjoy others from his time period. I want to read this again during my college years, because I think it sets up some good guard-rails for thinking about natural and positive law in general.
A masterpiece of rights. Examines the nation, state and individual as a society member. Effects of 7 Years War benefited this work. Secular religious ideas and just theories about international relations.
