Annulment of the marriage of King Louis VII of France and Queen Eleanor of Aquitaine.

Louis VII, called the Younger or the Young to differentiate him from his father Louis VI, was King of France from 1137 to 1180. His first marriage was to Duchess Eleanor of Aquitaine, one of the wealthiest and most powerful women in western Europe. The marriage temporarily extended the Capetian lands to the Pyrenees.

Eleanor of Aquitaine was Duchess of Aquitaine from 1137 to 1204, Queen of France from 1137 to 1152 as the wife of King Louis VII, and Queen of England from 1154 to 1189 as the wife of King Henry II. As the reigning duchess of Aquitaine, she ruled jointly with her husbands and two of her sons, the English kings Richard I and John. As the heiress of the House of Poitiers, which controlled much of southwestern France, she was one of the wealthiest and most powerful women in Western Europe during the High Middle Ages.
