Of his intrigues, the most important of which was his encouragement of the revolt of John of Procida against the French in Sicily, ever memorable as the Sicilian Vespers, it can only be said that they may have saved him from attack. Catalan mercenaries, who after the expulsion of the French from Sicily came into the service of the Empire, overwhelmed its fairest provinces with rapine and disaster. It is a history which makes Gibbon for once ascend the pulpit of the preacher of righteousness. "I shall not, I trust, be accused of superstition; but I must remark that, even in this world, the natural order of events will sometimes assume the strong appearances of moral retribution. The first Palæologus had saved his Empire by involving the kingdoms of the West in rebellion and blood; and from these seeds of discord uprose a generation of iron men, who assaulted and endangered the Empire of his son."
Andronicus II., indeed, had a long but disastrous reign. He continued his father's works at the harbour of the Kontoscalion. He repaired the sea walls, and in 1317, when his wife, Irene, died and left him some money, the impoverished Cæsar was able to undertake a general repair of the whole of the fortifications. Otherwise he is known in the history of the city only for his disputes with the patriarch, his abject submissions, and his misfortunes. His son, Michael IX., was from 1295 to 1320 the associate of his throne, and won universal praise. His grandson, Andronicus III., sank to the pleasures which had disgraced so many of his predecessors, but when his iniquities were too flagrant to be concealed, when his brother Manuel was murdered, it was believed, through his orders, and his father, Michael IX., died of grief, he took up arms against his grandfather, secured his own coronation, and then the absolute submission of the aged Emperor. Andronicus lived in 1332 in the great palace, but in absolute penury. He took monastic vows and died, no longer as Emperor, but as the poor monk Antony.
Andronicus the younger (III.), though he married princesses of Western houses, did not add to the dignity of the Eastern Empire. He died in 1341, and left behind him a child of eight, the son of his second wife, Agnes of Savoy. He was protected by John Cantacuzene, who had protected his father, and finally won him the crown, and who himself bore a character that was high among the best of the Byzantine statesmen and generals. But palace intrigues and attacks of interested politicians against him, at last obliged him, as he declares--for he is his own historian--to assume the Imperial title. In the war that ensued it seems that while the people supported the Palæologi, the officials supported the new claimant. It gave the opportunity to the Servian king, Stephen Dashan, to extend his territories and threaten to replace the Emperors as leaders of the Greek peoples. Strip by strip the territory of the Empire was shorn away, and Serbians, Turks, and Albanians left little to be conquered by Cantacuzene. At last, after previous failures, he advanced to the walls again in 1347 and was admitted secretly by his friends through the Golden Gate. For once, what was practically a change of dynasty was accomplished without bloodshed. John Cantacuzene became Emperor and gave his daughter in marriage to John Palæologus. It is said by a contemporary that so poor were even the imperial houses that at the wedding feast the illustrious personages had to be served in earthenware and pewter: strange change from the time when the very walls of the palace glittered with gold. In seven years the balance of power changed completely. War, first joint against the Serbians, then hostile against each other, was ended, it seemed, in favour of Cantacuzene by the assistance--a woeful precedent--of the Turks, now settled in Europe and the masters of Adrianople. But when the successful Emperor tried to associate his son Matthew on the throne, the feeling of Constantinople turned strongly against him. In 1358, John Palæologus whose seat of government had been fixed at Thessalonica, arrived, with but two galleys and two thousand men, on a dark night at the gate of the Hodegetria on the Sea of Marmora. Bringing their vessels quite close to the gate, they made every sign of distress, throwing out oil-jars and uttering cries for help. The stratagem succeeded; the guards opened the gate and came to their assistance. They were overpowered, and the troops rushed in and captured the adjoining tower. The city rose in favour of the young Palæologus, and John Cantacuzene with great willingness, if he is to be believed in his own case, retired from the throne and entered a monastery, where he died in 1383.
