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.
Anglo-Scottish Wars
France also played a key role throughout the period of the Anglo-Scottish Wars. Scots and English soldiers on French soil during the Hundred Years War (1337–1453) generally fought on opposing sides, with the Scots standing for the French against the English under the Auld Alliance. France in later periods, in turn, often intervened on Scottish soil for the Scots. This French involvement had increasingly complex political consequences for all sides by the later 16th century.
