Jean Balue was a French cardinal and minister of Louis XI. Born without resources, he managed to climb the political ladder by exploiting connections, to whom he often did not remain loyal, and by making himself an indispensable agent of the king's purposes in a time of political disorder in France. His services were as much military as ecclesiastical, bringing him the critical task of defending the city of Paris against the King's enemies. His work as a diplomat in dealing with Duke Francis of Brittany and with Charles de France brought him the office of first minister to the King. Balue overreached himself in negotiating a treaty between the King and Charles the Bold, who had become Duke of Burgundy and was trying to recover all his family inheritance. Secret correspondence revealed that he might have been playing both sides in the negotiation, and he was arrested, and held on charges of treason from 1469 to 1481, while King and Pope argued over jurisdiction. After the death of King Louis and Pope Sixtus, the new French king, Charles VIII, appointed Balue his ambassador in Rome.

Louis XI, called "Louis the Prudent", was King of France from 1461 to 1483. He succeeded his father, Charles VII. Louis entered into open rebellion against his father in a short-lived revolt known as the Praguerie in 1440. The king forgave his rebellious vassals, including Louis, to whom he entrusted the management of the Dauphiné, then a province in southeastern France. Louis's ceaseless intrigues, however, led his father to banish him from court. From the Dauphiné, Louis led his own political establishment and married Charlotte of Savoy, daughter of Louis, Duke of Savoy, against the will of his father. Charles VII sent an army to compel his son to his will, but Louis fled to Burgundy, where he was hosted by Philip the Good, the Duke of Burgundy, Charles' greatest enemy.
