city for Melun. In August she staged an entry to Paris for the Dauphin, and early in the new year, Charles signed an ordinance giving the 13-year-old the power to rule in the Queen's absence. During these years, Isabeau's greatest concern was the Dauphin's safety as she prepared him to take up the duties of the King; she formed alliances to further those aims. At this point, the Queen and her influence were still crucial to the power struggle. Physical control of Isabeau and her children became important to both parties and she was frequently forced to change sides, for which she was criticized and called unstable. She joined the Burgundians from 1409 to 1413, then switched sides to form an alliance with the Orléanists from 1413 to 1415. At the Peace of Chartres in March 1409, John the Fearless was reinstated to the Royal Council after a public reconciliation with Orléans' son, Charles, Duke of Orléans, at Chartres Cathedral, although the feuding continued. In December that year, Isabeau bestowed the tutelle (guardianship of the Dauphin) upon John the Fearless, made him the master of Paris, and allowed him to mentor the Dauphin, after he had Jehan de Montagu, Grand Master of the King's household, executed. At that point, the Duke essentially controlled the Dauphin and Paris and was popular in the city because of his opposition to taxes levied by Isabeau and Orléans. Isabeau's actions with respect to John the Fearless angered the Armagnacs, who in the fall of 1410 marched to Paris to "rescue" the Dauphin from the Duke's influence. At that time, members of the University of Paris, Jean Gerson in particular, proposed that all feuding members of the Royal Council step down and be immediately removed from power. To defuse tension with the Burgundians, a second double marriage was arranged in 1409. Isabeau's daughter Michelle married Philip the Good, son of John the Fearless; Isabeau's son, the Dauphin Louis, married John's daughter Margaret. Before the wedding, Isabeau negotiated a treaty with John the Fearless in which she clearly defined family hierarchy and her position in relation to the throne. Civil war Despite Isabeau's efforts to keep the peace, the Armagnac–Burgundian Civil War broke out in 1411. John gained the upper hand during the first year, but the Dauphin began to build a power base; Christine de Pizan wrote of him that he was the savior of
