The Dauphin is the son of King Charles of France, and heir to the throne (Dauphin).
He is a headstrong, impulsive, condescending and foolish young man who disregards King Henry entirely and pays the price for it. Thinking it a great joke, he sends tennis balls to Henry as being better suited to his age, and by doing so precipitates the war. He is infuriated when Harfleur falls and insists on joining the army to fight the English, despite his father’s order to the contrary. He adores his horse, and is vaingloriously overconfident about the French chances. Defeat leaves him distraught. His is disinherited by the terms of the peace treaty, which states that Henry will take the throne after Charles’s death. Historically, he is the older brother to Charles the Dauphin in Henry VI, Part One.
