Simon III of Montfort

Simon III of Montfort, called the Bald (1117–1181), was count of Évreux from 1140 and lord of Montfort-l'Amaury from 1137, younger son of Amaury III. His father had divided his lands between his sons, but the death of Amaury IV reunited Évreux and Montfort under Simon.

For Montfort the family owed allegiance to the French king, and for Évreux to the English king, placing it amid their rivalry. Simon sided with Henry II of England and surrendered his fortresses to him. He later reconciled with Louis VII. Simon died in 1181.
