Andronicus II was a man who, with few personal vices, possessed many of the worst qualities of a sovereign. He had capacity enough to direct the whole civil and ecclesiastical business of the empire, but was destitute of the judgment necessary to direct it well. He rarely took a right step, and never at the proper time; so that his petulant pride and pedantic despotism proved more ruinous to the empire than the worst vices of many of his predecessors. His ecclesiastical bigotry especially served as an instrument of providence for effecting the ruin and degradation of the orthodox Eastern church, and of the Greek race. That the Greeks allowed themselves to be so long misled and oppressed by so worthless and weak a sovereign, may perhaps be accepted as a proof that the nation was sunk in selfishness and bigotry like the emperor.[c]
Andronicus III, now absolute monarch, showed great bravery against the Turks, but he could not stay their progress in Anatolia, nor prevent their descents on Europe. Neither could he complete the conquest of Epirus nor live at peace with his neighbours on the peninsula.
He died in 1341, leaving his son, Joannes V (Palæologus), a minor, under the regency of his wife, Anne of Savoy. The lord chamberlain, Cantacuzenus, affected at first to protect them, but his protégés soon found him too powerful. They got up scandals about him, imprisoned his relatives, allowed the houses of his partisans to be destroyed. These latter forced him to take the crown under the title of Joannes VI. Civil war again broke out in the empire. Cantacuzenus allied himself with Stephen, krall of Servia, and with Omur Beg, the Seljuk emir of Ionia. Anne of Savoy asked help from the latter’s rival, Orkhan, sultan of the Ottomans.
Intrigue alternated with massacre. Cantacuzenus contrived to gain over this same Orkhan by giving him his daughter Theodora. On both sides the infidels were authorised to carry off Byzantine subjects, and the ports and vessels of the empire were placed at their disposal to enable them to transport their captives into Asia. The foreigners took advantage of the general anarchy to oppress the provinces and towns. The krall of Servia conquered Macedonia as far as Pheræ, and called himself czar of the Greeks and Servians. The Genoese retook Chios, which Andronicus III had seized from them, and blockaded Constantinople, defended by other Italians, under Facciolati.
The latter, whilst the empress was giving a banquet to her partisans, opened the Golden Gate to Cantacuzenus. Anne was obliged to come to an agreement. It was arranged that Cantacuzenus should be emperor first, but only for ten years; that is, until Joannes V attained his twenty-first year. The partisans of neither side were satisfied with this transaction.
So feeble was the empire that the Genoese ventured to impose their own will in the very capital. Cantacuzenus had tried to reconstruct an Hellenic navy, and attempted to bring a little life into the port of Byzantium by lowering the port dues. The Genoese considered this injurious to their Galatian colony. They massacred the crew of a Grecian ship, and exacted that a large territory adjoining Galata should be ceded to them. A war followed, which lasted four years (1348-1352). To fight the Genoese the Greeks had called in Venetian and Catalan fleets. A bloody naval battle was fought under the very walls of the town, and the Greeks were victorious. Cantacuzenus had to capitulate (May 6, 1352) and give them all they demanded.
Civil war also soon recommenced. The whole country was horribly ravaged. An Ottoman army under Suleiman (Solyman), son of Orkhan and in Cantacuzenus’ pay, carried off the inhabitants by thousands. Joannes V was despoiled of his authority and private domains; in the room of the fallen prince, Matthias, son of Joannes VI, was associated with his father and crowned emperor at St. Sophia (1354). Then, in 1355, with the concurrence of Francesco Gattilusio and other Genoese, Palæologus surprised and entered Constantinople. He had to negotiate.
Joannes V and Joannes VI continued to live in the palace with equal authority. Matthias was to keep the crown for life, as well as Hadrianopolis. Lesbos had ceded its full sovereignty to Gattilusio (1355).
Joannes VI did not feel at all secure. Perhaps he felt remorse for having brought so many evils on the empire; perhaps he had a fit of religious fervour and contempt for worldly things, but at any rate he donned the monkish garb and retired into the convent of Mangana (1355). He only came out to join his prayers to the threats of Joannes V in order to make Matthias lay aside the purple (1357).
