Ferdinand II Declares Himself King of Navarre and the Siege of Tudela (August 1512)

By late August 1512, Ferdinand II of Aragon declared himself King of Navarre de jure proprio (by his own right), asserting that Navarre was now legally and permanently part of his dominions. This marked a crucial step in the full annexation of Navarre into the Crown of Castile and Aragon.


Ferdinand’s Justification for His Claim

  • Ferdinand II, having successfully occupied Pamplona and most of Navarre, sought to legitimize his conquest through a legal claim to the throne.
  • His propaganda campaign, backed by papal bulls issued by Pope Julius II, framed the invasion as a crusade against a schismatic monarchy, even though Navarre had remained neutral in the Italian Wars.
  • By declaring himself King of Navarre, Ferdinand sought to erase the legitimacy of Queen Catherine I and King John III of Albret, who had fled to Lower Navarre and Béarn.

The Siege of Tudela (August–September 1512)

  • Tudela, a major stronghold in southeastern Navarre, remained one of the last cities resisting Castilian control.
  • Alfonso of Aragon, Ferdinand’s bastard son and Archbishop of Zaragoza, was given command of the siege.
    • He led 3,000 infantry and 300 cavalry, determined to subdue the city by force.
  • The siege of Tudela became one of the final major battles of the Castilian invasion, as Ferdinand aimed to eliminate all resistance in Upper Navarre.

Outcome and Legacy

  • Tudela’s resistance delayed Castile’s total victory, but ultimately, the city would fall to Castilian forces.
  • The siege further solidified Castilian dominance over Upper Navarre, leaving only a few remaining rebel strongholds.
  • By 1513, Navarre’s integration into Castile was virtually complete, though Navarrese loyalists and the House of Albret continued their fight from Béarn and Lower Navarre.

Ferdinand’s declaration as King of Navarre in 1512 and the siege of Tudela were key moments in the final conquest of Navarre, ensuring Spanish control over the kingdom for centuries to come.
