The End of the Navarrese Civil War…

The End of the Navarrese Civil War and Castile’s Strategic Gains (August 1476)

In August 1476, negotiations held in Tudela resulted in an accord that ended the Navarrese Civil War, a conflict that had divided the Kingdom of Navarre between pro-Castilian and pro-French factions. The resolution of this war was a major geopolitical success for Ferdinand of Aragon, as it significantly strengthened Castilian influence in Navarre and secured Spain’s northern frontier against France.

Navarre’s Strategic Importance in the War of the Castilian Succession

• Navarre was a key battleground between France and Castile, as its location between the two kingdoms made it a buffer state.
• The French invasion attempt at Fuenterrabía (March–June 1476) had failed, and Ferdinand took the opportunity to increase Castile’s control over Navarre.
• By negotiating an end to the internal Navarrese conflict, Ferdinand weakened French influence and reinforced his position in northern Iberia.
