Hundred Years' War
The Hundred Years' War was a series of conflicts waged from 1337 to 1453 by the House of Plantagenet, rulers of the Kingdom of England, against the French House of Valois, over the right to rule the Kingdom of France. Each side drew many allies into the war. It was one of the most notable conflicts of the Middle Ages, in which five generations of kings from two rival dynasties fought for the throne of the largest kingdom in Western Europe. The war marked both the height of chivalry and its subsequent decline, and the development of strong national identities in both countries.
History of Hertfordshire
Hertford Castle was used as a gaol for a series of important captives during the Hundred Years' War. This was actually a series of separate wars that lasted a total of 116 years, between 1337 and 1453. The Plantagenet Kings of England fought the Valois Kings of France, almost entirely on French soil. Queen Isabella was imprisoned by her son, the King, in Hertford Castle in 1330, as were King David II of Scotland and his queen in 1346, after the Battle of Neville's Cross. King John II of France was imprisoned there in 1359 in considerable luxury.
