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.
History of France
A succession crisis following the death of the last direct Capetian monarch in 1328 led to the series of conflicts known as the Hundred Years' War between the House of Valois and the House of Plantagenet. The war formally began in 1337 following Philip VI's attempt to seize the Duchy of Aquitaine from its hereditary holder, Edward III of England, the Plantagenet claimant to the French throne. Despite early Plantagenet victories, including the capture and ransom of John II of France, fortunes turned in favor of the Valois later in the war. Among the notable figures of the war was Joan of Arc, a French peasant girl who led French forces against the English, establishing herself as a national heroine. The war ended with a Valois victory in 1453.
