トロワ条約
On 21 May 1420, the Treaty of Troyes was signed in this city, still under control of the Burgundians, by which Henry V of England was betrothed to Catherine, daughter of Charles VI. Under the terms of the treaty, Henry V was to succeed Charles, to the detriment of the Dauphin. The high-water mark of Plantagenet hegemony in France was reversed when the Dauphin, afterwards Charles VII, and Joan of Arc recovered the town of Troyes in 1429 for French control by armed conflict (Siege of Troyes).
