Our system of international law has been developed over a period of more than three centuries. It is distinctly Western and European in origin. In tracing its growth, we usually refer to the Spanish jurist-theologians of the sixteenth century, but we ascribe first place to Hugo Grotius whose great book on "The Law of War and Peace" was first published in 1625.
