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
The Anglo-Norman dynasty that had ruled England since the Norman conquest of 1066 was brought to an end when Henry, the son of Geoffrey of Anjou and Empress Matilda and great-grandson of William the Conqueror, became the first of the Angevin kings of England in 1154 as Henry II. The Angevin kings directly ruled over more French territory than the kings of France. However, they still owed homage for these territories to the French king. From the 11th century onward, the Angevins had autonomy within their French domains, effectively neutralising the issue.
