Later, King Francis I again gave the duchy as an appanage to his mother, Louise of Savoy, by letters patent of 4 February 1515. On her death, in September 1531, the duchy returned into the king's possession. In 1552 it was given as an appanage by Henry II to his son Henry of Valois, who, on becoming king in 1574, with the title of Henry III, conceded it to his brother Francis, duke of Alençon, at the treaty of Beaulieu near Loches (6 May 1576). Francis died on 10 June 1584, and the vacant appanage definitively became part of the royal domain.
