Gaston, Prince of Viana
Gaston, Prince of Viana, also called Gaston de Foix, was the son of Gaston IV of Foix and Eleanor of Navarre, and was the heir of both. As a Prince of Navarre, he was called Prince of Viana.
He married Magdalena of Valois, a daughter of Charles VII of France and Marie of Anjou on 7 March 1461 at Lescar. They had two children:
Gaston died in 1470 from wounds received in a jousting tournament in Libourne, Aquitaine, before his accession to the throne of Navarre. Consequently, Francis I and Catherine I rose to the throne successively, but it was Gaston's wife Magdalena who actually pulled the strings of the crown all the way to Catherine's marriage to John III of Albret in 1494, and her death in 1495.
