Lords, counts and dukes of Montfort-l'Amaury

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

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.
