support of the Kingdom of England. The Armagnacs through treaty with the English King Henry IV, to secure his military aid; the Burgundians by remaining neutral when the English invaded Normandy. That neutrality led to Orléans's capture by the English at Agincourt in 1415. After Armagnac's murder by a Burgundian mob in Paris in 1418, leadership of the party devolved upon the young Dauphin, who retreated to Bourges. After 1418, then, Burgundy controlled both Paris and the person of the king. However, the whole dispute was proving deleterious to the war effort against the English, as both sides focused more on fighting one another than on preventing the English from conquering Normandy. In 1419, the Duke and the Dauphin negotiated a truce to allow both sides to focus on fighting the English. However, in a further parley, the Duke was murdered by the Dauphin's supporters as revenge for the murder of Orléans twelve years before. Burgundian party leadership passed to Philip III, Duke of Burgundy. Duke Philip entered an alliance with England. Due to his influence and that of the queen, Isabeau, who had by now joined the Burgundian party, the mad king was induced to sign the Treaty of Troyes with England in 1420, by which Charles VI recognized Henry V of England as his heir, disinheriting his own son the Dauphin. When Henry V and Charles VI both died within months of each other, leaving Henry's son Henry VI of England as heir to both England and France, Philip the Good and the Burgundians continued to support the English. Nevertheless, dissension grew between Philip and the English regent, John, Duke of Bedford. Although family ties between Burgundy and Bedford (who had married the Duke's sister) prevented an outright rupture during Bedford's lifetime. Burgundy gradually withdrew support for the English and began to seek an understanding with the Dauphin, by now Charles VII of France. The two sides finally reconciled at the Congress of Arras in 1435, resulting in a treaty which allowed the French king to finally return to his capital.
