Battle of Najera
The Battle of Nájara (also called Navarette) was fought near Burgos in northern Spain on 3rd April 1367, between forces led by Edward the Black Prince and Pedro the Cruel on one side and Henry of Trastamara (Pedro’s half-brother) on the other.
The prize was the crown of Castile, previously usurped by Henry from Pedro. The battle was a resounding success for the prince, and adds to his status as the pre-eminent battle-commander of the age.
In historic terms the battle did little. Within two years, with French assistance, Henry had regained the throne. Edward stayed out of it this time – he was busy reorganising the finances of his principality (Aquitaine), raising taxes, due to Pedro having reneged on payment for his previous assistance.
