Anjou
Anjou was a French county centred on Angers. In 1337 John of Valois, the future King John II, held it as a royal appanage.
In 1360 John made his son Louis duke, founding the Valois-Anjou line, which inherited Provence and a claim to Naples in 1382. The line ended with the death of Good King René in 1480, and Louis XI absorbed Anjou into the royal domain in 1482.
