Answer
The Dauphin, Charles VII, was disinherited after the assassination of John the Fearless, Duke of Burgundy, in 1419. The Dauphin was held responsible for John's death and was subsequently disowned by his father, Charles VI, in favor of Henry V of England. This action sparked outrage and fueled conflicts between the Armagnacs, supporters of the Dauphin, and the Burgundians, allies of the English, thus further intensifying the Hundred Years' War.
