Geopolitics & Diplomacy

  • Queen Isabella I of Castile died on November 26, leaving a disputed succession and raising questions about the future political relationship between Castile and Aragon.
  • The Treaty of Blois was signed between France and the Holy Roman Empire, with Louis XII ceding his claims to the Kingdom of Naples to Ferdinand of Aragon.
  • Spain consolidated its control over the Kingdom of Naples under the viceroyalty of Gonzalo Fernandez de Cordoba, establishing a Spanish administration that would last over two centuries.
  • Ferdinand of Aragon assumed the regency of Castile following Isabella's death, though her will designated their daughter Joanna as queen with her husband Philip of Burgundy as consort.

Conflict & Security

Economy & Finance
