The Treaty of Picquigny was a peace treaty negotiated on 29 August 1475 between England and France. Louis XI of France paid Edward IV of England to return to England and not take up arms to pursue his claim to the French throne. Edward was provided with an immediate payment of 75,000 crowns and a yearly pension thereafter of 50,000 crowns. Also the King of France was to ransom Queen Margaret of Anjou with 50,000 crowns. It also included pensions to many of Edward's lords. A notable exception was Edward's brother Richard, Duke of Gloucester (later Richard III), who opposed the treaty and refused the pension Louis offered.
