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 (1415–53)
The following five years witnessed the peak of English power, extending from the Channel to the Loire, excluding only Orléans and Angers, and from Brittany in the west to Burgundy in the east. But this was achieved with ever-decreasing resources of man-power.
