Hugo Grotius' treatise on The Law of War and Peace (1625) was a pioneering work in framing a comprehensive system of international relations and the law of nations. Though he drew extensively from biblical texts for his analysis, he also quoted extensively from classical Roman and Greek philosophers, poets and jurists. In a break from the Calvinists of his day, he believed the laws of nature and of nations were able to be derived from mankind's experience as well as from revelation. He wrote this treatise, in part, as a response to the common practice of waging war "without any reference of law, Divine or human." Click here to view this book in its entirety.

"In giving to our treatise the title 'The Law of War,' we mean . . . to inquire whether any war can be just, and then, what is just in war. For law in our use of the term here means nothing else than what is just . . .. [T]here is no controversy which may not give rise to war. In undertaking to treat the law of war, therefore, it will be in order to treat such controversies, of any and every kind, as are likely to arise. War itself will finally conduct us to peace as its ultimate goal." Hugo Grotius, from The Law of War and Peace (1625).
