من تزوج Charles de Viane؟

Charles de Viane, né le 29 mai 1421 à Peñafiel et mort le 23 septembre 1461 à Barcelone, fils du prince Jean d'Aragon, est duc de Gandie, prince de Gérone, prince de Viane, puis roi de Navarre sous le nom de Charles IV (1441).

À partir de 1441, il est en conflit avec son père, usurpateur du trône de Navarre, contre qui il se révolte et qui finit par le déshériter.

Rentré en 1460 en Aragon pour tenter de se réconcilier, Charles de Viane meurt prématurément l'année suivante, laissant la voie du trône ouverte à son demi-frère Ferdinand, qui deviendra roi consort de Castille en 1474 et roi d'Aragon en 1479.

Agnes of Cleves (1422–1448) was a daughter of Adolph I, Duke of Cleves and his second wife Marie of Burgundy, Duchess of Cleves, daughter of John the Fearless duke of Burgundy.

In 1439, Agnes married Charles, Prince of Viana. He had been bequeathed the kingdom of Navarre. His right to be King of Navarre had been recognised by the Cortes; but when his mother Blanche died in 1441, her husband King John II of Aragon had seized the kingdom to the exclusion of his son. Charles and Agnes had no children.

Agnes died on 6 April 1448, aged only 25 or 26. After Agnes' death, her husband decided to remarry with his choice being Infanta Catherine of Portugal. However, Charles died in 1461 before the marriage could take place.
