Prince Louis married on 25 July 1137 to Eleanor, Duchess of Aquitaine, heiress of William X of Aquitaine. In this way, Louis VI sought to add the large, sprawling territory of the Aquitaine to his family's holdings in France. Shortly after the marriage of his son to Eleanor of Aquitaine, King Louis the Fat died on August 1, 1137. Thus, Prince Louis became King of France reigning as "Louis VII."
