Antoine Marini (known in Latin as Anthonius Marini de Gratianopoli) was a 15th-century humanist, theologian and political thinker who, among other things, contemplated the establishing of a European Court of Justice and a pan-European parliament. He was born in Grenoble, France.
Marini served as adviser to King George Podiebrad of Bohemia, and in this office was mainly concerned with curtailing the political power of the Papacy and the growth of the Ottoman Empire after in conquered Constantinople in 1453. In 1461 he published a treatise calling for the establishment of a federal union of all Christian states in Europe for the purpose of deciding on political matters out of considerations for the common interests of Europe, while establishing counterweight to Papal authority, and blocking the advance of the Turkish Empire.[1]
