Francisco de Vitoria

Francisco de Vitoria was a Spanish Roman Catholic philosopher, theologian, and jurist of Renaissance Spain. He is the founder of the tradition in philosophy known as the School of Salamanca, noted especially for his contributions to the theory of just war and international law. He has in the past been described by some scholars as one of the "fathers of international law", along with Alberico Gentili and Hugo Grotius, though contemporary academics have suggested that such a description is anachronistic, since the concept of international law did not truly develop until much later. American jurist Arthur Nussbaum noted that Vitoria was "the first to set forth the notions of freedom of commerce and freedom of the seas."
