The House of Tudor was an English and Welsh dynasty that held the throne of England from 1485 to 1603. They descended ultimately from Ednyfed Fychan and the Tudors of Penmynydd, a Welsh noble family, and Catherine of Valois. The Tudor monarchs were also descended from the House of Lancaster. They ruled the Kingdom of England and the Lordship of Ireland for 118 years with five monarchs: Henry VII, Henry VIII, Edward VI, Mary I and Elizabeth I. The Tudors succeeded the House of Plantagenet as rulers of the Kingdom of England, and were succeeded by the Scottish House of Stuart. The first Tudor monarch, Henry VII, was descended through his mother from the House of Beaufort, a legitimised branch of the English royal House of Lancaster, a cadet house of the Plantagenets. The Tudor family came to power and started the Tudor period in the wake of the Wars of the Roses (1455–1487), which had resulted in the main House of Lancaster becoming extinct in the male line.
