Charles III of Navarre

Lore & Background

Charles III was born at Mantes on 22 July 1361, the firstborn son of King Charles II of Navarre and Joan of Valois. As a young man, he was frequently sent by his father as envoy to France. He married Eleanor of Castile in 1375, sealing peace between their fathers. Their early marriage suffered a long crisis over the status of their daughters and his illegitimate children; the couple reconciled after Charles affirmed their daughters' exclusive right to succeed him. Charles became king on 1 January 1387 and recovered the last Castilian-occupied parts of Navarre that same year.

Charles skillfully secured a balanced web of alliances through the marriages of his sisters and daughters to French lords and Iberian princes, ensuring long-lasting peace in Navarre. He strove to increase royal prestige through art patronage, court extravagance, and construction works. Having outlived most of his children, he was succeeded by his third daughter, Blanche I.
