The Treaty of Brétigny in 1360 exchanged John for 83 other hostages while waiting for cash payments totaling three million écus. Edward would renounce his claim to the French throne, and France would allow him to hold several areas without owing allegiance to the French throne. John also gave over to England two of his sons: Louis I the Duke of Anjou, and John, Duke of Berry; they were held in Calais, under English control.
In 1362, Louis of Anjou decided he had enough and escaped captivity, against the terms of the treaty. King John was appalled, and felt honor-bound to return to captivity in England. He ultimately was hosted at the Tower of London, where he died in 1364.
Every account of John's captivity and freedom and return mentions that he minted the franc when he first was released in order to stabilize the French economy. Since I've been talking about currency recently, I suppose it's fair to give the franc its moment in the spotlight. See you next time.
