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 (1337–1360)
After the treaties of London failed Edward launched the Rheims campaign which, though largely unsuccessful, led to the Treaty of Brétigny which settled certain lands in France on Edward for renouncing his claim to the French throne. This was in part caused by Black Monday (1360), the freak storm that devastated the English army and forced Edward III into peace talks. This peace lasted nine years; but then began a second phase of hostilities known as the Caroline War.
