I suggest to modify this event:
#-#The league of Cognac didn't prove to be a solid alliance against Charles V' Spanish and imperial troops. The Pope, taken captive by the lansquenets sacking Rome, abandoned the league. Genoa, important for military supply to the French troops fighting in Southern Italy, had turned to Spain thanks to the decisions of Andrea Doria who, dissatisfied by François Ier's misbehaviour to the Republic, preferred to offer his services to the Emperor. Since the military campaign in Italy was becoming too expensive for both sides and the political instability in the Empire due to religious conflicts was worsening, Louise of Savoy, François Ier's mother and regent of France, together with Margarete of Habsburg, Charles V's aunt and his representative in the administration of the Burgundian dominions, stipulated a peace treaty at Cambrai on 5 august 1529. The so called Ladies' Peace was successful, the signatories were the only ones who could have influence in the political decisions of the two monarchs and managed to induce them to make peace for the wealth of their respective countries. Signing that treaty, France had to renounce her claims to Milan, Asti, Flanders and Artois, while Spain gave up her inheritance rights to the Duchy of Bourgogne, a French fief. François Ier had also to withdraw all his troops from Italy and marry Eleanor, Charles's sister, in return for the liberation of his two sons, hostages at the Spanish court because of François Ier's disrespect for the treaty of Madrid. At Cambrai France abandoned her plans of expansionism in Italy while all her Italian allies joining the league of Cognac would be now at the Emperor's mercy. The Republic of Florence would experience Charles V's rule.
Ile de France added in case Spain owned the province, especially as the result of Burgundian inheritance.
