Information:  - Louis VII (called the Younger or the Young) (1120  18 September 1180) was King of the Franks from 1137 until his death. He was the son and successor of King Louis VI of France, hence his nickname, and married Eleanor of Aquitaine, one of the wealthiest and most powerful women in western Europe. Eleanor came with the vast Duchy of Aquitaine as a dowry for Louis, thus temporarily extending the Capetian lands to the Pyrenees, but their marriage was annulled in 1152 after no male heir was produced.  - Alix of France ( July -- August 1150 -- 1197/1198 ) was the second daughter born to King Louis VII of France and Duchess Eleanor of Aquitaine .  - Louis VI (1 December 1081  1 August 1137), called the Fat, was King of the Franks from 1108 until his death (1137). Chronicles called him "roi de Saint-Denis". Louis was the first member of the House of Capet to make a lasting contribution to the centralizing institutions of royal power, He spent almost all of his twenty-nine-year reign fighting either the "robber barons" who plagued Paris or the Norman kings of England for their continental possession of Normandy.

She was the patron of literary figures such as Wace, Benoît de Sainte-Maure, and Bernart de Ventadorn. She led armies several times in her life, and was a leader of the Second Crusade.  - The Ramnulfids, or the House of Poitiers, were a French dynasty ruling the County of Poitou and Duchy of Aquitaine in the 9th through 12th centuries.
