トロワ条約
French losses in the first phase of the conflict (1337–60) were partly reversed in the second (1369–96); but Henry V's shattering victory at the battle of Agincourt in 1415 against a France now bitterly divided between rival Armagnac and Burgundian factions of the royal house was to lead to his son Henry VI's recognition as king in Paris seven years later under the 1420 Treaty of Troyes, reducing Valois rule to the lands south of the Loire River Valley.
