King James died in 1327, and was succeeded by his second son, Alfonso, his first son having voluntarily renounced his claims that he might, tradition says, give himself up more completely to his vices.[a] Alfonso IV was doomed to much annoyance from the recent conquest of Sardinia. In 1330 the Genoese, incensed that the Catalans, their rivals in commerce, should have obtained a settlement in seas which they considered as exclusively their right, not only fomented a spirit of disaffection among the islanders, but sent a fleet to invest the capital. A bloody war ensued, the details of which would afford little interest. To stay these hostilities the pope frequently interfered, but without effect; the Genoese insisted on an ample indemnification for the expenses of their armaments; the Aragonese would consent to none. Thus the warfare raged during the whole of this prince’s reign. Alfonso, like his predecessors, was not averse to encourage the rebellions which at this period almost continually afflicted Castile; but without deriving any ultimate advantage from his ungenerous policy. If the internal state of his own kingdom was tranquil, it was not so in his own house. His eldest son and destined successor, Don Pedro, offended that he had bestowed on Alfonso--another son, by a second wife--some domains of the crown, complained loudly of his prodigality. The queen, Leonora of Castile, at whose instigation the alienation had been made, cherished a deep resentment against her stepson. Pedro despised her anger; and, to incense her the more, seized on Jativa, which had been assigned to her on her marriage with his father, and loudly proclaimed his intention of revoking every grant made by the king, whenever he should succeed to the sovereignty. It was not in Alfonso’s power to stifle these dissensions, which not only imbittered his peace but aggravated the hydropsical disease under which he had long suffered. He died at Barcelona, in 1336. [Sidenote: [1336-1347 A.D.]] No sooner had Pedro IV ascended the throne, than Queen Leonora, apprehensive of the consequences of her late quarrel with him, fled to Fraga, whence she implored the protection of her brother Alfonso, king of Castile. Alfonso naturally espoused his sister’s cause. The pope despatched a legate to exhort the two kings to settle their dispute by negotiations, and to insist on justice being done to Queen Leonora. Their deliberations ended in nothing, beyond a suspension of actual hostilities. Some years having elapsed, in 1345 the king, so far from wishing to do his stepmother justice, endeavoured to seize the domains belonging to his two brothers, Ferdinand and Juan, on the pretext that the revenues of the crown were materially injured by the prodigality of their common father. On the representations of the Castilian king, he again suspended, though he was far from abandoning, his purpose. The troubles which agitated his kingdom will account for this temporary forbearance.
