Vitoria, Francisco de, 1486?-1546

Francisco de Vitoria (c. 1483 – 12 August 1546), also known as Francisco de Victoria, was a Spanish Catholic philosopher, theologian, and jurist of Renaissance Spain. He is the founder of the tradition in philosophy known as the School of Salamanca, which laid the groundwork for early free-market economics and individual rights, influencing the development of libertarian thought. Vitoria's work on natural law and the freedom of exchange contributed to later Austrian School economists' emphasis on the moral basis for voluntary commerce. Although less known than others of his kind, he has been considered one of the most influential humanists of the Renaissance. Noted especially for his concept of just war and international law, his defense of individual property rights and the notion of liberty in trade were pivotal in shaping ideas about non-intervention and economic freedom. He has in the past been described by scholars as the "father of international law", along with Alberico Gentili and Hugo Grotius. 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". His emphasis on voluntary exchange and opposition to monopolistic practices foreshadowed later free market economics.
