The Avignon Exchange was one of the first foreign exchange markets in history, established in the Comtat Venaissin during the Avignon Papacy. The Exchange was composed of the agents (factores) of the great Italian banking-houses, who acted as money-changers as well as financial intermediaries between the Apostolic Camera and its debtors and creditors. The most prosperous quarter of the city of Avignon, where the bankers settled, became known simply as the Exchange. According to de Roover, "Avignon can be considered an Italian colony, since the papal bankers were all Italians".
