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.
Peasant revolt in Flanders 1323–1328
When the Hundred Years War started, Louis remained steadfast in his pro-French policy, despite the county's economic dependence on England. His actions resulted in an English boycott of the wool trade, which in turn sparked a new insurrection under Jacob van Artevelde. In 1339, the count fled his Flemish lands, never able to return. Louis was killed in the Battle of Crécy in 1346.
