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 concept of just war and international law. He has in the past been described by scholars as the "father of international law", along with Alberico Gentili and Hugo Grotius, though some contemporary academics have suggested that such a description is anachronistic, since the concept of postmodern international law did not truly develop until much later. American jurist Arthur Nussbaum noted Vitoria's influence on international law as it pertained to the right to trade overseas. Later this was interpreted as "freedom of commerce".
