Etienne Marcel implored Charles to intercede with the Dauphin but he achieved nothing and the land around Paris began to be plundered both by Charles's forces and by the Dauphin's. In the last days of May the peasant rebellion of the Jacquerie erupted to the north of Paris as a spontaneous expression of hatred for the nobility that had brought France so low. Etienne Marcel publicly declared Parisian support for the Jacquerie. Unable to get help from the Dauphin, the knights of northern France appealed to Charles of Navarre to lead them against the peasants.
