The Wars of the Roses saw family fight family over the greatest prize - the throne of England. But what gave the eventual victor of these brutal and complex wars, Henry Tudor, the right to claim the crown? How exactly did an illegitimate line come to challenge the English monarchy? While the Houses of York and Lancaster fought brutally for the crown, other noble families of the kingdom also played integral roles in the wars; grand and prestigious names like the Howards, Mowbrays, Nevilles and Percys were intimately involved in the conflict, but none symbolised the volatile nature of the period quite like the House of Beaufort. Their rise, fall, and rise again is the story of England during the fifteenth century, a dramatic century of war, intrigue and scandal, both at home and abroad. This book uncovers the rise of the Beauforts from bastard stock of John of Gaunt, Duke of Lancaster, to esteemed companions of their cousin Henry V, celebrated victor of Agincourt, and tracks their chastening fall with the House of Lancaster during the 1460s and 1470s. The hopes and fortunes of the family gradually came to rest upon the shoulders of a teenage widow named Margaret Beaufort and her young son Henry. From Margaret would rise the House of Tudor, the most famous of all England's royal houses and a dynasty that owed its crown to the blood of its forebears, the House of Beaufort. From bastards to princes, the Beauforts are medieval England's most captivating family.
