Margaret of France (November 1157 - August/September 1197) was the eldest daughter of Louis VII of France by his second wife Constance of Castile. She was married to Henry the Young King of England on 2 November 1160. Henry was the second of five sons born to King Henry II of England and Eleanor, Duchess of Aquitaine. He was five years old at the time of this agreement while Margaret was only two. Margaret's dowry was the vital and much disputed territory of Vexin.[1][2]
Her husband became co-ruler with his father in 1170. For unknown reasons, Margaret was not crowned along with her husband on 14 July 1170, an omission that greatly angered her father. In order to please the French King, Henry II had his son and Margaret crowned together in Winchester Cathedral on 27 August 1172.[3] Margaret became pregnant and gave birth to their only son William on 19 June 1177. The child was born prematurely and died on 22 June of the same year.
