Gaston IV, Count of Foix

Gaston IV, born on February twenty-sixth, fourteen twenty-three, was a prominent nobleman in France, serving as the sovereign Viscount of Béarn and the Count of Foix and Bigorre from fourteen thirty-six until his death in fourteen seventy-two. His extensive titles also included the viscounties of Marsan, Castelbon, Nébouzan, Villemeur, and Lautrec, and he held the distinguished position of co-prince of Andorra through his governance of the county of Foix.

Gaston was the son of John I, Count of Foix, and Jeanne I d'Albret. His lineage included notable figures such as his maternal grandparents, Charles d'Albret, a Constable of France who met his end at the Battle of Agincourt, and Marie de Sully. In fourteen forty-one, he married Infanta Eleanor of Navarre, the daughter of John II and Blanche I of Navarre, which further solidified his status in the region.

Initially, Eleanor faced limited prospects due to her family's complex royal lineage, with her father being a younger son and her siblings standing in line for the throne of Navarre. However, the tides turned as family dissent and untimely deaths paved the way for Eleanor's father to claim the Navarrese crown. In a strategic move, he promised the succession to Navarre to Eleanor and Gaston in exchange for their loyalty, which they honored.

Upon Gaston IV's death in fourteen seventy-two, he left behind a legacy intertwined with the Kingdom of Navarre. His eldest son, Gaston, Prince of Viana, had already passed away, leading to the succession of his grandson, Francis Phoebus, who was merely five years old at the time. Under the regency of Eleanor, Gaston IV's wife, Francis Phoebus would later become King of Navarre in fourteen seventy-nine, linking the fate of the County of Foix to the Kingdom of Navarre until their eventual incorporation into the Kingdom of France in sixteen oh seven.
