Born in secrecy in 1431 as the son of the Welsh squire Owen Tudor and dowager Queen Katherine of Valois, Jasper Tudor was never supposed to live life at the political centre of England. But this all changed dramatically after the death of his mother, followed shortly by the arrest of his father, when he was no older than six. After spending most of their youth inside an abbey being raised by nuns and priests, Jasper and his older brother Edmund were suddenly called to court by their half-brother King Henry VI. Here, in 1452, they became the first ever Welshmen elevated to the English peerage. When this happened both brothers stepped into a completely new life of political involvement with its many attendant problems, problems that Edmund did not survive. After this, Jasper led a life that was completely dominated by his devotion to the Lancastrian cause and to his nephew, the only son of his death brother Edmund, Henry Tudor. In a time when most magnates defected to the other party as soon as their own faction became submerged, Jasper remained loyal to his kinsman’s cause and supported him wherever it took him, whether scaling triumphant peaks or – more often – through deep valleys. His hopes and faith in what was right led him through several kingdoms and, as a brave and fearless man, he led the life of an adventurer throughout that most difficult period of English history, the Wars of the Roses. Historians often claim that Jasper’s father Owen or his brother Edmund was the founder of the Tudor dynasty; certainly both men played a significant role in its origins and without them the Tudors would not have been. But Jasper’s story proves he was the key figure and godfather of the Tudor dynasty.
