When the Viking chieftain Rollo obtained the territories via the Treaty of Saint-Clair-sur-Epte which would later make up Normandy, he distributed them as estates among his main supporters. Among these lands were the seigneurie of Harcourt, near Brionne, and the county of Pont-Audemer, both of which Rollo granted to Bernard the Dane, ancestor of the lords (seigneurs) of Harcourt. The first to use Harcourt as a name, however, was Anquetil d'Harcourt at the start of the 11th century.

However, Marie and her son John of Vaudémont were able to control the entire inheritance until 1454, when the de Rieux gained control of the County of Aumale.
