Nottingham element: Eleanor of Aquitaine
Eleanor was one of the most powerful women of the Middle Ages. Duchess of Aquitaine in her own right, she became queen-consort of France and later queen of England.
In 1173 two of Eleanor's sons involved her in a plot against their father, her second husband Henry of Anjou who captured and imprisoned her in Nottingham Castle. After Henry's death in 1189, his eldest son, Richard I, ordered his mother's release.
