During these thirteen years (1328–1341) war was constantly being waged against the Turks. The emperor himself was always in delicate health, and died at the age of forty-five. He continued his great friendship until his death with Cantacuzenus, and invited him, even as early as 1329, to occupy the throne as co-emperor, and the offer was renewed.[52] Cantacuzenus, notwithstanding that he was pressed to accept by the only noble near him in rank, Apocaukus, who afterwards became his great enemy, refused. The emperor, however, continued to treat him as a friend, and was constantly accompanied by him on his various expeditions.
Appeals for aid to the pope.
Like every emperor from the recapture of Constantinople down to 1453, Andronicus turned his attention to the West and sought to obtain aid against the Turks, even at the price of coercing his people into a Union with Rome. The Turks had invaded Macedonia and attacked Euboea and Athens. As the southern portion of the Balkan peninsula was still ruled in part by the descendants of the crusading barons and by the remnant of the Catalans, there was reason to believe that the pope would be ready to arouse the West against the common enemy of Christendom. Accordingly the emperor took advantage of the passage of Dominican missionaries through Constantinople from Tartary to convey to Pope John the Twenty-second his desire for Union and his request for aid. The pope replied by sending preachers and by urging the emperor to do all he could to accomplish his part. His successor in 1335 grew alarmed at the attacks made by the Turks by sea on various places in the Mediterranean, and finding that the Catalans had seized Athens from Gautier de Brienne, who held it as his duchy, he excommunicated them. He invited Andronicus to join the king of France and Naples in a Crusade against the Turks which the Venetians and the Genoese had promised also to aid. The emperor gladly gave his consent and sent a number of ships, but the needs of Cyprus, which was being attacked by the Saracens, were decided to be more pressing than those of the empire, and the Crusade was not proceeded with. Andronicus in 1339 sent Barlaam, the author of many controversial works, to the pope, at that time in Avignon. On his arrival he pointed out that the Turks had seized the seats of four metropolitan sees, and he suggested that as a condition of the Union of the Churches the Turks should be expelled from Asia Minor. The pope recognised the desirability of such an attempt as keenly as many of his successors, but saw that the condition was impossible.
Death of Andronicus the Third. Reign of John (1341 to 1391), Cantacuzenus (1342 to 1355.)
Andronicus on his death, in 1341, left a son, John Palaeologus, who was then nine years old. His mother, Anne of Savoy, was a woman of ability and energy. Cantacuzenus was associated with her as regent. He held the dignity of Grand Domestic, and in the later years of his life wrote a clear and able statement of the history of his own times. He had been, as we have seen, the intimate friend of Andronicus and his great supporter when the grandfather of the same name endeavoured to exclude him from the throne. He had been named by his friend and patron as the guardian of John, but the widow of the emperor was from the first jealous of her co-guardian and never worked sympathetically with him. He tells us that from the death of Andronicus he was constantly urged to occupy the imperial throne and that he as constantly refused. He undoubtedly possessed the confidence of a large majority of the nobles. There was a general recognition that, in the existing state of the empire, it was unwise to leave the government in the hands of a boy and of a foreign princess. Ducas expressly states that Cantacuzenus ultimately allowed himself to be proclaimed emperor because his friends urged him to take the reins of government from the hands of a woman and a child and because the empress and the senate were unjust and unfair to him.[53] In 1342 he was proclaimed joint emperor under the style of John Cantacuzenus.
During the thirteen years of his reign, which lasted till 1355, the history of the empire is in the main one of civil war and consequent decadence. Distrusted by Anne, the mother of the boy emperor, his difficulties were increased by the turbulent character of his ward, whom his mother could not, or would not, restrain from wilfulness which led him even in early youth into debauchery. The result was that during the whole of Cantacuzenus’s reign there was a constant strain between the elder emperor, on the one side, and the empress and her son on the other. Cantacuzenus states that Apocaukus, the noble next to himself in rank, had suggested to him that he should assume imperial authority and that he had rejected the suggestion as treason to the empress and her sons and to the memory of the emperor. But Apocaukus, with the support of the patriarch, soon formed a party, nominally for the empress and her son, really against Cantacuzenus. The patriarch himself claimed to be the guardian of the infant John, excommunicated those who abandoned him, and even Cantacuzenus himself.[54] The account given by the emperor of his reluctance to accept the crown might be regarded with distrust if Nicephorus Gregoras, who after he had become a bitter enemy wrote his history of the events of the reign, were not on this point in substantial accord with Cantacuzenus. Even before his accession the troops, according to Gregoras, declared that they would recognise no other regent than the Grand Domestic, and proposed to make the oath of fidelity to the young emperor and his mother conditional upon the recognition of Cantacuzenus as tutor of John and regent of the empire.
In presence of the opposition of Anne, Cantacuzenus offered to resign, but the empress desired that he should remain, probably fearing revolt in case his resolution was carried into effect. Among much which is doubtful, it is clear that he had the confidence of the army and that the empress had not.
Civil war soon broke out between the new emperor and the partisans of John and his mother. Apocaukus was named governor of Constantinople by Anne and excited the population against Cantacuzenus apparently with the intention of having himself elected emperor by a popular vote.
Meantime the rivalries of these two nobles allowed foreign enemies to make progress. Two divisions of Turks were ravaging the empire in one direction, while a band of Tartars who had crossed the Danube had advanced as far as Didymotica. Stephen of Serbia had already marched southwards and was rapidly consolidating the strength of his country. In 1344 the discontent at the civil war had become so great that the nobles insisted that the empress Anne and Apocaukus should send an embassy to Cantacuzenus to make peace. When this attempt failed, Apocaukus, according to Cantacuzenus, endeavoured on two occasions to have him assassinated. Driven thus to extremities, the emperor promised his daughter Theodora in marriage to the Turk Orchan, the son and successor of Othman, who thereupon sent an army of five thousand men to assist in the struggle against the partisans of John.
Apocaukus had thrown into the prisons of Constantinople the partisans of his rival and had ordered them to be treated with unusual barbarity. He was then incautious enough to venture into prison among them. They fell upon him, slew him, stuck his head upon a spike, and showed it to the citizens. Next day, however, at the instigation of his widow, the prisoners were all killed.
