Eleanor of Aquitaine was born around 1122. Her grandfather, William IX, was the wealthy and powerful duke of Aquitaine. He was also a musician and poet, acknowledged as history's first troubadour.
William IX didn't just sing about love. He married for the first time while he was still in his teens, but apparently he and his wife Ermengarde didn't get along, and the marriage was annulled. His second wife was Philippa (or Maud) of Toulouse, the widowed queen of Aragon. They had two sons, William and Raymond, and five daughters. When the Troubadour tired of Philippa, she moved to the same nunnery where Ermengard lived. After Philippa's death, Ermengarde tried to force William to take her back, but the duke had other ideas. He had abducted a married woman called Dangereuse ("dangerous" in French), and she was now his mistress.
In time the Troubadour decided that his elder son, William, should marry Dangereuse's daughter Aenor. (Dangereuse's husband was Aenor's father.) The younger William didn't want to marry Aenor, but he had no choice. The marriage took place in 1121, and a year or so later Eleanor of Aquitaine was born. She was followed by a daughter, Aelith (or Petronella) and a son, William Aigret.
When Eleanor was about five years old, William the Troubadour died and her father became Duke William X. A few years later, Eleanor's mother and brother died. Now Eleanor was heir to the vast realm of Aquitaine.
Like his father, William X was a patron of the troubadours and storytellers, and growing up in his court Eleanor developed a lifelong love of music and literature. Proud of his lively, intelligent daughter, William gave her an excellent education. She travelled through Aquitaine with him, preparing for her future role of duchess. Father and daughter were close, and it must have been a harsh blow for Eleanor when William, while making a religious pilgrimage, died suddenly of food poisoning.
Eleanor was just fifteen, and her life was about to change forever. On his deathbed William had asked his men to commend Eleanor to the care of Louis the Fat, king of France. Louis was no fool. He knew just what to do with his young, very beautiful, extremely wealthy ward -- marry her off to his own son and heir. And so on August 1, 1137, Eleanor of Aquitaine married the future King Louis VII.
