Eleanor, Fair Maid of Brittany
Eleanor Fair Maid of Brittany, also known as Damsel of Brittany, Pearl of Brittany, or Beauty of Brittany, was the eldest daughter of Geoffrey II, Duke of Brittany, the fourth son of King Henry II of England, and Constance, Duchess of Brittany. After the presumed death in 1203 of her imprisoned younger brother, Arthur, she was heiress to vast lands including England, Anjou, and Aquitaine as well as Brittany, realms where the Salic Law barring the accession of females did not apply. Her uncle John, King of England was the fifth son of Henry II, and Eleanor inherited Arthur's claim to the throne as child of John's elder brother Geoffrey. Thus she posed a potential threat to John, and following his death in 1216, equally to her cousin, Henry III of England. She was imprisoned from 1202, and thus became the longest-imprisoned member of an English royal family. As a prisoner she was also unable to press her claim to the Duchy of Brittany as her mother's heiress.
