The congress gave rise to the second Treaty of Arras, which was signed on 20/21 September 1435 and became an important diplomatic achievement for the French in the closing years of the Hundred Years' War. Overall, it reconciled a longstanding feud between King Charles VII of France and Duke Philip III of Burgundy (Philip the Good). Philip recognized Charles VII as king of France and, in return, Philip was exempted from homage to the crown, and Charles agreed to punish the murderers of Philip's father Duke John I of Burgundy (John the Fearless).
