Charles III, Count of Alençon

Charles III of Alençon (1337–1375) inherited Alençon and Perche as a boy after his father Charles II fell at Crécy in 1346. In 1361 he renounced his titles, entered the Dominican convent in Paris, and with John II's approval left Alençon to his brother Peter and Perche to Robert. At the insistence of his kinsman King Charles V, he became archbishop of Lyon on 13 July 1365; the cathedral chapter, defending its right to elect independently, accepted him only after three rounds of voting.

As primate he fiercely defended the see's rights; when a royal official tried to seize his temporal power in 1372, he imposed an interdict that lasted until his death on 5 July 1375.
