 Despite all these alliances, Peter kept his bad relationship with the Kingdom of France.On 30 March 1282 there was a popular uprising in the Kingdom of Sicily called the Sicilian Vespers, against the government of Charles I of Anjou.The noble sicilian rebels asked for Peter for help and offered him the crown as they considered his wife Constance their rightful Queen, and after receiving an embassy from the people of Palermo at Alcoy, Peter landed at Trapani on 30 August 1282.
