Overview

Comté du Vexin; the borderland astride the river Epte between Normandy and the royal domain (the Norman Vexin and the French Vexin). Of great strategic importance — it was on the Epte at Saint-Clair that Rollo was granted Normandy. The French Vexin, tied to the advocacy of the Abbey of Saint-Denis (source of the Oriflamme, the royal battle-standard), was absorbed into the royal domain; the Norman Vexin was a perennial flashpoint between the Capetian and Angevin kings.
