Louis d'Anjou (1339– 1384)
Marie de Blois Chatillon(1345-1404)



Louis I of Anjou (July 23, 1339 – September 20, 1384), or Louis I of Naples, was the second son of King John II of France and Bonne of Luxembourg.
He was the Count of Anjou (1356–1360), Duke of Anjou (1360–1384), Count of Maine (1356–1384), Duke of Touraine (1370–1384), and titular King of Naples and Jerusalem and Count of Provence and Forcalquier from 1382 to 1384.
He was a member of the House of Valois-Anjou.

He was present at the Battle of Poitiers (1356), in the battalion commanded by his brother Charles, the Dauphin. They hardly fought and the whole group escaped in the middle of the confrontation.
Although humiliating, their flight allowed them to avoid capture by the English, who won the battle decisively. King John II and Louis' younger brother Philip were not so fortunate and were captured by the English, commanded by Edward, the Black Prince.
From 1380 to 1382 Louis served as regent for his nephew, King Charles VI of France, but left France in the latter year to claim the throne of Naples following the death of Queen Joanna I.
She had adopted him to succeed her, as she was childless and did not wish to leave her inheritance to any of her close relatives, whom she considered enemies. He was also able to succeed her as count of Provence and Forcalquier.
Despite his incoronation at Avignon as King of Naples by Antipope Clement VII, Louis was forced to remain in France and Joan's troops were defeated by Charles of Durazzo, her second cousin and previous heir. Joanna was killed in her prison in San Fele in 1382; Louis, with support of the Antipope, France, Bernabò Visconti of Milan and Amadeus VI of Savoy, and using the money he had been able to obtain during the regency, launched an expedition to regain the Kingdom of Naples from Charles.

They had the following children:
Marie (1370 – after 1383)
Louis II of Anjou (1377 – 1417)
Charles (1380 – 1404, Angers), Prince of Taranto, Count of Roucy, Étampes, and Gien
