The Battle of Nájera, also known as the Battle of Navarrete, was fought on 3 April 1367 between an Anglo-Gascon army and Franco-Castilian forces near Nájera, in the province of La Rioja, Castile. The English were led by Edward, the Black Prince, and John of Gaunt, Duke of Lancaster, allied with Peter of Castile against his brother Henry of Trastámara. Peter and Henry had been in armed conflict, the Castilian Civil War, for some time before the intervention of foreign powers was sought. Peter begged assistance from the Black Prince in Bordeaux to restore him to his throne. James IV of Majorca also agreed to support Peter. Wikipedia [ - ]
