Henry assumed the government of Castile under difficulties. As the illegitimate son of King Alfonso XI, he met with strong opposition. Moreover his right to the throne was contested by others besides a large body of the Castilian nobility. King Ferdinand of Portugal, who had renewed the alliance which his father had concluded with Don Pedro, tried to win the crown of Castile for himself after the murder of the latter, on the ground that he, being the grandson of Beatrice, princess of Castile, was the only male descendant born in lawful wedlock. To support his claim he allied himself with Muhammed, the Moorish prince of Granada. Like Pedro IV of Aragon, he received with all honour the malcontent and fugitive Castilian nobles. He paid no heed to the murmurs of the Portuguese at their king’s liberality to foreigners, but marched into Galicia with an army, while the Moors took Algeciras; and the king of Aragon endeavoured to unite Molina, Almazan, Soria, and other frontier districts with his own dominions. At the same time the duke of Lancaster, uncle of Richard II, assumed the title of king of Castile in right of his wife, the eldest daughter of Don Pedro, and was acknowledged as such by the English court. But Henry extricated himself from the difficulties that encompassed him in his own country with prudence and skill, and turned the disadvantages of his opponents to his own profit; and thus he succeeded in putting down all resistance and seated himself firmly on the throne of Castile, though he was still regarded by enemies as a usurper. The Moorish conquests were confined to Algeciras; the king of Portugal, who also styled himself “king of Castile,” carried on the war with so little success that the Spanish historian López de Ayala[b] says that it would have been more to his honour to have discontinued the campaign; the English had their hands full in their own country, and the Aragonese, besides having their attention diverted by a war in Sardinia, found themselves, by Henry’s shrewd contrivance, confronted with another adversary in the person of James III of Majorca, the pretender to the throne of the Balearic kingdom.
