15. Battle of Aljubarrota (1385)
The Battle of Aljubarrota, fought on August 14, 1385, was a decisive conflict between the Kingdom of Portugal and the Crown of Castile. Portuguese forces, led by King John I and Constable Nuno Álvares Pereira, with support from English allies, faced the Castilian army commanded by King John I of Castile. Despite being outnumbered, the Portuguese achieved a decisive victory, effectively ending Castilian ambitions to annex Portugal. This triumph secured Portuguese independence and led to the establishment of the House of Aviz, which played a pivotal role in the Age of Discoveries, significantly impacting global exploration (fundacao-aljubarrota.pt).
