Henry VI is the youngest monarch ever to have ascended the English throne and the only English king to have been acknowledged by the French as rightfully King of France. His reign was the third longest since the Norman conquest and he came close to being declared a saint. This masterly study, unparalleled in its informative detail, examines the entire span of the king's reign, from the death of Henry V in 1422, when Henry was only nine months old, to the period of his insanity at the beginning of the Wars of the Roses, his dethronement in 1461 and his murder ten years later. This classic reassessment of the third Lancastrian king is essential reading for anyone interested in the history of fifteenth-century England. The third edition includes an additional chapter on recent research.
