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.
Joan of Arc
The Hundred Years' War had begun in 1337 as an inheritance dispute over the French throne, interspersed with occasional periods of relative peace. Nearly all the fighting had taken place in France, and the English army's use of "chevauchée" tactics (destructive "scorched earth" raids) had devastated the economy. The French population had not regained its former size prior to the Black Death of the mid-14th century, and its merchants were isolated from foreign markets. Prior to the appearance of Joan of Arc, the English had nearly achieved their goal of a dual monarchy under English control and the French army had not achieved any major victories for a generation. In the words of DeVries, "The kingdom of France was not even a shadow of its thirteenth-century prototype."
