Owen Tudor, aka Owain ap Maredudd ap Tudor (c. 1400-1461 CE), was a Welsh courtier who secretly married Catherine of Valois (l. 1401 - c. 1437 CE), the former wife of Henry V of England (r. 1413-1422 CE) and mother of Henry VI of England (r. 1422-61 & 1470-71 CE). The couple had several children, one of whom was Edmund Tudor whose son Henry Tudor would become Henry VII of England (r. 1485-1509 CE) and so found the royal house of Tudor. The Tudors would rule England until 1603 CE in what many regard as the country's Golden Age. Owen Tudor, a staunch supporter of Henry VI during the Wars of the Roses (1455-1487 CE) dynastic dispute, was captured and beheaded by Yorkist forces in 1461 CE.
