Constance of Normandy

Constance of Normandy was born between 1057 and 1061 in Normandy as the daughter of William the Conqueror and Matilda of Flanders. Her birthplace was Normandy, where her father held the title of duke. Although William of Jumièges, a chronicler of the Norman conquest of England, lists her as the second daughter of her parents, the exact birth order of their daughters is not documented.

In 1086, Constance married Alan IV, Duke of Brittany, in an arrangement made by her father to secure peace on his Western border. Her administrative abilities were akin to those of her mother. Historical accounts of her personality are conflicting; William of Malmesbury depicted her as having a severe and conservative manner, which did not endear her to many, while Orderic Vitalis described her as caring and considerate, earning the affection of her subjects. Allegations from William of Malmesbury suggest that her husband may have been involved in her death by poisoning on 13 August 1090.
