Hugo Grotius (1583-1645) was a Dutch legal scholar. He is considered one of the key founders of international law.
Into the very midst of all this welter of evil, at a point in time to all appearance hopeless, at a point in space apparently defenseless, in a nation of which every man, woman, and child was under sentence of death from its sovereign, was born a man who wrought as no other has ever done for a redemption of civilization from the main cause of all that misery; who thought out for Europe the precepts of right reason in international law; who made them heard; who gave a noble change to the course of human affairs; whose thoughts, reasonings, suggestions, and appeals produced an environment in which came an evolution of humanity that still continues.
