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.
Congress of Arras
The Congress of Arras was a diplomatic congregation established at Arras in the summer of 1435 during the Hundred Years' War, between representatives of England, France, and Burgundy. Toward the close of the Hundred Years' War, both the Congress and the subsequent Treaty of Arras represented diplomatic failures for England and major successes for France.
