Hundred Years' War (1415–53)
The Lancastrian War was the third and final phase of the Anglo-French Hundred Years' War. It lasted from 1415, when King Henry V of England invaded Normandy, to 1453, when the English lost Bordeaux. It followed a long period of peace from the end of the Caroline War in 1389. The phase was named after the House of Lancaster, the ruling house of the Kingdom of England, to which Henry V belonged.
Hundred Years' War (1369–89)
The Treaty of Bruges was a treaty signed in 1375 between France and England in Bruges, present-day Belgium. The conference leading to the treaty was called at the instigation of Pope Gregory XI. France was represented in the negotiations by Philip II, Duke of Burgundy and England by John of Gaunt, 1st Duke of Lancaster. Negotiations broke down over the issue of sovereignty over the Aquitaine. The English wanted full sovereignty over Edward's territories, while the French insisted that the House of Valois
retain sovereignty of any Plantagenet provinces. Despite attempts by the Pope to broker a compromise, agreement could not be reached and the war resumed in 1377.
