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 November 1434, leaving no children. The duchy of Anjou then passed to his brother René, second son of Louis II and Yolande of Aragon.
