Mouzon

Mouzon was a lordship on the Meuse in the Ardennes, on the frontier of France and the Holy Roman Empire. In 1337 its fortified town belonged to the archbishops of Reims.

Lands held of Mouzon, including Sedan, were attached to the French crown by treaty in 1379. In 1424 Évrard III de La Marck acquired Sedan through a delayed dowry. The Treaty of Saint-Maur gave the lordship to Duke John II of Lorraine in 1465, and in the sixteenth century it was absorbed into the Principality of Sedan.
