The Duchy of Anjou (, ; ; ) was a French province straddling the lower Loire. Its capital was Angers, and its area was roughly co-extensive with the diocese of Angers. Anjou was bordered by Brittany to the west, Maine to the north, Touraine to the east and Poitou to the south. The adjectival form is Angevin, and inhabitants of Anjou are known as Angevins. In 1482, the duchy became part of the Kingdom of France and then remained a province of the Kingdom under the name of the Duchy of Anjou. After the decree dividing France into departments in 1790, the province was disestablished and split into six new départements: Deux-Sèvres, Indre-et-Loire, Loire-Atlantique, Maine-et-Loire, Sarthe and Vienne. Duchy of Anjou The county of Anjou was united to the royal domain between 1205 and 1246, when it was turned into an apanage for the king's brother, Charles I of Anjou. This second Angevin dynasty, a branch of the Capetian dynasty, established itself on the throne of Naples and Hungary. Anjou itself was united to the royal domain again in 1328, but was detached in 1360 as the Duchy of Anjou for the king's son, Louis I of Anjou. The third Angevin dynasty, a branch of the House of Valois, also ruled for a time the Kingdom of Naples. The dukes had the same autonomy as the earlier counts, but the duchy was increasingly administered in the same fashion as the royal domain and the royal government often exercised the ducal power while the dukes were away. On 17 February 1332, Philip VI bestowed it on his son John the Good, who, when he became king in turn (22 August 1350), gave the countship to his second son Louis I, raising it to a duchy in the peerage of France by letters patent of 25 October 1360. Louis I, who became in time count of Provence and titular king of Naples, died in 1384, and was succeeded by his son Louis II, who devoted most of his energies to his Neapolitan ambitions, and left the administration of Anjou almost entirely in the hands of his wife, Yolande of Aragon. On his death (29 April 1417), she took upon herself the guardianship of their young son Louis III, and, in her capacity of regent, defended the duchy against the English. Louis III, who also devoted himself to winning Naples, died on 15
