Vexin
Vexin (French pronunciation: [vɛksɛ̃]) is a historical county of northern France. It covers a verdant plateau on the right bank (north) of the Seine running roughly east to west between Pontoise and Romilly-sur-Andelle (about 20 km from Rouen), and north to south between Auneuil and the Seine near Vernon. The plateau is crossed by the Epte and the Andelle river valleys.
The name Vexin is derived from a name for a Gaulish tribe now known as the Veliocasses. They had inhabited the area and made Rouen their most important city.
Vexin was divided into two parts—the French Vexin in the east and the Norman Vexin in the west—under the Treaty of Saint-Clair-sur-Epte on 11 July 911. King Charles III the Simple ceded to the Norman leader Rollo the territory between the Epte in the north, the Avre in the south, and the sea, laying the groundwork for the future Duchy of Normandy, which included part of Vexin, while the remainder stayed under the French king's control.
In 1031, Duke Robert I of Normandy aided King Henry I against a revolt led by the dowager queen, Constance of Arles, and was rewarded with the French Vexin between the Epte and Oise, including Pontoise.
The County of Vexin was held by a prominent feudal lord, Raoul de Gouy, who also controlled the counties of Amiens and Valois. In 1063, Gauthier III de Gouy was poisoned and died a prisoner of William the Bastard. His cousin Ralph IV of Valois succeeded him, and his only son, Simon de Vexin, entered a monastery in 1077. In 1082, King Philip I of France seized the opportunity to reclaim the French Vexin, previously granted by his father to the Duke of Normandy.
This division sparked centuries of conflict between the two neighbors, especially after the Duke of Normandy became King of England in 1066, fueling the ambitions of both rulers.
In 1087, William the Conqueror, back in Normandy, pillaged the French Vexin during the summer, clashing with King Philip I, and suffered a fatal injury during the assault on Mantes.
The Epte valley was then heavily fortified, with numerous military structures built by both the French king and the Norman duke. Notable surviving examples include Gisors, Neaufles-Saint-Martin, and Château-sur-Epte on the Norman side, and Trie-Château and La Roche-Guyon on the French side, along with the castle of Pontoise, the historic Vexin capital, where King Louis VI the Fat often resided. Nonetheless, these fortifications did little to prevent over a century of pillaging and devastation in the region.
