Lords, counts and dukes of Montfort-l'Amaury

This list is about the lords, counts and dukes who ruled over Montfort-l'Amaury, France.

Around ten years before 1000 AD, Robert the Pious commissioned Guillaume de Hainaut with protecting the royal domain around Paris from the counts of Blois to the west. Guillaume built a castle on a hill and called it Montfort; his son Amaury founded a town nearby which received the name of Montfort-l'Amaury, thus becoming the first seigneur of Montfort-l'Amaury.
