Hugo Grotius (/ ˈɡroʊʃiəs /; 10 April 1583 -- 28 August 1645), also known as Huig de Groot (Dutch: (ˈɦœyɣ də ɣroːt)) or Hugo de Groot (Dutch: (ˈɦyɣoː də ɣroːt)), was a Dutch jurist. Along with the earlier works of Francisco de Vitoria and Alberico Gentili, Grotius laid the foundations for international law, based on natural law. A teenage intellectual prodigy, he was imprisoned for his involvement in the intra-Calvinist disputes of the Dutch Republic, but escaped hidden in a chest of books. He wrote most of his major works in exile in France.
