During what years was the English Royal House, that was at one point ruled by King Henry VII, in reign?
House of Tudor The House of Tudor was an English royal house of Welsh origin, descended in the male line from the Tudors of Penmynydd. Tudor monarchs ruled the Kingdom of England and its realms, including their ancestral Wales and the Lordship of Ireland (later the Kingdom of Ireland) from 1485 until 1603, with five monarchs in that period. The Tudors succeeded the House of Plantagenet as rulers of the Kingdom of England, and were succeeded by the House of Stuart. The first Tudor monarch, Henry VII, descended through his mother from a legitimised branch of the English royal House of Lancaster. The Tudor family rose to power in the wake of the Wars of the Roses, which left the House of Lancaster, to which the Tudors were aligned, extinct.
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 House of Valois, rulers of the Kingdom of France, over the succession to the French throne. 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.
