title: Joan of Arc
text: The young Charles of Orléans succeeded his father as duke and was placed in the custody of his father - in - law , the Count of Armagnac . Their faction became known as the `` Armagnac '' faction , and the opposing party led by the Duke of Burgundy was called the `` Burgundian faction '' . Henry V of England took advantage of these internal divisions when he invaded the kingdom in 1415 , winning a dramatic victory at Agincourt on 25 October and subsequently capturing many northern French towns . In 1418 Paris was taken by the Burgundians , who massacred the Count of Armagnac and about 2,500 of his followers . The future French king , Charles VII , assumed the title of Dauphin -- the heir to the throne -- at the age of fourteen , after all four of his older brothers had died in succession . His first significant official act was to conclude a peace treaty with the Duke of Burgundy in 1419 . This ended in disaster when Armagnac partisans assassinated John the Fearless during a meeting under Charles 's guarantee of protection . The new duke of Burgundy , Philip the Good , blamed Charles for the murder and entered into an alliance with the English . The allied forces conquered large sections of France .
