Charles V signs the Peace of Crépy with Francis I without consulting his ally and military partner, Henry VIII. By the terms of the agreement, conquests since the Truce of Nice (1538) are restored. France surrenders its claims to Naples, Flanders, Artois, Gelderland and Zutphen, while in return Charles surrenders his claim to Burgundy, and the territories of Piedmont and Savoy are to be returned to their rulers. The Emperor also promises a wife for Francis's second son, the Duke of Orleans, either his daughter Mary or his niece, but this marriage never takes place since Orleans dies the following year.
