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.
Second Hundred Years' War
Like the Hundred Years' War, this term does not describe a single military event but a persistent general state of war between the two primary belligerents. The use of the phrase as an overarching category indicates the interrelation of all the wars as components of the rivalry between France and Britain for world power. It was a war between and over the future of each state's colonial empires.
