After the fall of the Western Roman Empire, the area became part of the County of Provence. After a time of turmoil, the death of Queen Joanna I in Naples, caused a war of succession for the County of Provence. An alliance of several Provençal towns (Aix, Nice and Tarascon) supported Charles of Durazzo, Queen Joanna I's adversary, murderer and successor, against Louis I of Anjou, brother of John II of France who was adopted by Queen Joanna in exchange of his help during the war against Charles of Durazzo. During summer 1383, Charles VI, King of France, Louis of Anjou's grandnephew, took action and mandated the Seneschal of Beaucaire, Enguerrand d'Eudin, to support Louis I in raising an army, thus conquering strongholds and villages, such as Lamanon. In 1384, Louis I of Anjou died after being crowned King of Naples (defeating Charles of Durazzo). Arles and Marseille, followed by a lot of towns, pledged allegiance to his son, Louis II of Anjou, who was only 7 years old. When his mother, Marie de Blois, Louis I's widow, arrived in Provence and asked Seneschal d'Eudin to give Lamanon up for Louis II, he refused on the name of Charles VI the King.
