A Navarrese princess whose life was a pawn in the brutal dynastic wars of 15th-century Iberia, dying imprisoned far from home.
Blanche of Navarre was born into a crown fractured by ambition. The daughter of Queen Blanche I and King John II, she was a key piece on the chessboard of Iberian politics from childhood. Her marriage to the future Henry IV of Castile was a political gambit to secure peace, but it proved childless and was eventually annulled, sending her back to Navarre. There, she aligned with her brother, Charles, Prince of Viana, in his bitter struggle against their father for the throne. After Charles's suspicious death, Blanche became the standard-bearer for the faction opposing John II, leading her father to see her not as a daughter but as a rival. He had her imprisoned, first in Navarre and then in France, where she died under circumstances that many believed were orchestrated. Her brief, tragic claim to the throne of Navarre was extinguished in captivity, a testament to the peril faced by royal women in a world ruled by men's power struggles.
