"Louis I (23 July 1339 – 20 September 1384) was the second son of John II of France and Bonne of Bohemia. Born at the Château ...
de Vincennes, Louis was the first of the Angevin branch of the French royal house. His father appointed him Count of Anjou and Count of Maine in 1356, and then raised him to the title Duke of Anjou in 1360 and Duke of Touraine in 1370.
In 1382, as the adopted son of Joanna I of Naples, he succeeded to the counties of Provence and Forcalquier. He also inherited from her a claim to the kingdoms of Naples and Jerusalem. He was already a veteran of the Hundred Years´ War against the English when he led an army into Italy to claim his Neapolitan inheritance. He died on the march and his claims and titles fell to his son and namesake, Louis II, who succeeded in ruling Naples for a time." - (en.wikipedia.org 13.06.2020)
