The Duke of Brittany

 “The Duke of Brittany” is the story of the brief but eventful career of Arthur, son of Geoffrey Plantagenet and Constance of Brittany. Geoffrey was the fourth son of Henry the Second of England and Eleanor, Duchess of Guienne. Upon the death of his brother Henry, Richard, surnamed the Lion-hearted, became the heir apparent and succeeded to the throne after the death of his father in 1189. Richard shortly afterward became one of the leaders of the Third Crusade, which ended disastrously.
