Amaury III of Montfort

Amaury III of Montfort (died 1137), a son of Simon I, succeeded his brother Simon II as lord of Montfort in 1101 and claimed the county of Évreux in 1118 when his uncle died. After Henry I annexed Évreux, Amaury formed a coalition with the French king and Norman barons.

He seized the town in 1118 and his supporters held its citadel after Henry burned it in 1119; at the council of Reims Henry granted him the county in exchange for the keep. Taxation disputes drove him to revolt again in 1123.

Captured at Bourgtheroulde in 1124, he was freed when his captor defected and later recovered the county. By Agnès de Garlande he left sons Simon III and Amaury IV, and he died in 1137.
