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
King John of England inherited the Angevin domains from his brother Richard I. However, Philip II of France acted decisively to exploit the weaknesses of John, both legally and militarily, and by 1204 had succeeded in taking control of much of the Angevin continental possessions. Following John's reign, the Battle of Bouvines (1214), the Saintonge War (1242), and finally the War of Saint-Sardos (1324), the English king's holdings on the continent, as Duke of Aquitaine (Guyenne), were limited roughly to provinces in Gascony.
