egotiations with Charles VI and Queen Isabeau begun at once and were concluded in May 1420 with the signing of the Treaty of Troyes, which finally, after eighty-three years of war, put the Plantagenet hand on the throne of France. The Dauphin Charles was declared a bastard, a murderer, and a rebel, and thrust aside from the succession. Queen Isabeau's apparent admission that her third son was illegitimate makes no mention of the supposed father.
Henry V became the heir of Charles VI by marriage to his daughter Catherine, younger sister of that Isabelle who had been married to Richard II. As 'son and heir presumptive' Henry V became the Regent and facto ruler of France, while retaining Normandy by right of conquest and all his ancestral territories in Aquitaine without homage. Henry swore to observe all the existing rights and customs of France and North of the Loire no voice was raised (or at least heard) against this Plantagenet position.
The marriage of Henry V and Catherine of Valois was celebrated at the church of St Jean in Troyes on 14th June 1420, and in July, after the English parliament had endorsed the Treaty, with the Caveat that no French customs were to be imported into England, the two kings, Charles VI and Henry V, now his son-in-law and heir, with his bride and mother-in-law, entered the good city of Paris, escorted by their faithful subject, the great Duke of Burgundy. Peace had finally arrived, or so it seemed, and all the remained was to stamp out some smouldering embers of rebellion.
