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.
Battle of Castillon
The term "Hundred Years' War" is misleading, as the fighting between the English and the French during the period of 1337 to 1453 was more a series of conflicts than a single prolonged war. Thus, the conflict(s) can be examined from the vantage point of various stages. The breakdown of the 1420 Treaty of Troyes began the final stage of the Hundred Years' War. This period from 1420 to 1453 is characterized by Anne Curry as the “wars of the Treaty of Troyes” for control of the crown of France.
