However, their plans to establish an autonomous kingdom ultimately failed when the last duke, Charles the Bold, sparked the Burgundian Wars of 1474 to 1477 and was killed in the Battle of Nancy in January 1477.
The Capetian House of Burgundy became extinct when Duke Philip I died in 1361, before he was able to consummate the marriage with Margaret of Dampierre, heiress of Count Louis II of Flanders.
As Charles VI suffered from increasing mental derangement, Philip tried to spread his influence across the French kingdom, which met with the fierce resistance by the king's younger brother Duke Louis I of Orléans.
The remaining tensions with the Orléans liensmen led to the French Armagnac–Burgundian Civil War, whereby Duke John allied with King Henry V of England and in 1418 occupied Paris, but was lured into an ambush and murdered by the Armagnac leader Tanneguy du Chastel the next year.
John's son Philip the Good, Duke of Burgundy from 1419, renewed his father's alliance with King Henry V of England when he signed the Treaty of Troyes in 1420 against the French Dauphin Charles VII.
By the 1435 Congress of Arras Duke Philip acknowledged the rule of King Charles VII of France and in turn reached the formal independence of the Burgundian lands from the French Crown.
