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.
Invasions of the British Isles
England was spared invasion during the Hundred Years' War against France and Castile, but it was plagued by 32 years (1455–1487) of civil wars known as the Wars of the Roses. The Lancastrian branch of the House of Plantagenet, which had overthrown the direct royal line in 1399, was embroiled in fighting against the Yorkist wing of the dynasty.
