At the time of her marriage to John, the blonde-haired blue-eyed Isabella was already renowned by some for her beauty and has sometimes been called the Helen of the Middle Ages by historians. Isabella was much younger than her husband and possessed a volatile temper similar to his own. King John was infatuated with his young, beautiful wife; however, his acquisition of her had at least as much to do with spiting his enemies as romantic love. She was already engaged to Hugh IX le Brun when she was taken by John. It was said that he neglected his state affairs to spend time with Isabella, often remaining in bed with her until noon. However, these were rumors spread by John's enemies to discredit him as a weak and grossly irresponsible ruler, given that at the time John was engaging in a desperate war against King Philip of France to hold on to the remaining Plantagenet duchies. The common people began to term her a "siren" or "Messalina", which spoke volumes as to popular opinion. Her mother-in-law, Eleanor of Aquitaine, readily accepted her as John's wife.
