Perche
Perche was a county between Normandy and Maine, with Bellême as its historical capital. In 1337 Charles II of Valois held it alongside Alençon, having inherited the lands from his father Charles of Valois.
Charles fell at Crécy in 1346, and English partisans plundered Perche during the Hundred Years' War. Reconstruction began in 1449 after English rule ended. When the last Valois duke of Alençon died childless in 1525, the county returned to the French royal domain.
