[1440-1448 A.D.]
The emperor Joannes, seeing public affairs in this hopeless state, thought only of keeping on good terms with the sultan. His brother Demetrius, however, who had accompanied him to Florence, shared his apostasy, and partaken of the papal bounty, now basely attempted to take advantage of the popular dissatisfaction with the union. He claimed the throne as being the first child of Manuel who was a Porphyrogenitus, but he trusted to gain his ends by the aid of Turkish troops rather than by the merits of his title or the preference of the Greeks. Collecting a large force composed of the Turkish nomads, who were ready to join any standard that offered them an opportunity of plundering and enslaving the Christians, Demetrius marched to besiege his brother in Constantinople. Sultan Murad took no direct part in the contest, but he allowed Demetrius to enrol Turkish troops without opposition, and viewed with satisfaction a rebellion which tended to weaken the empire. When called upon to choose between the two brothers, the Greek people acknowledged the superiority of the reigning emperor. Demetrius, after plundering the suburbs of Constantinople, saw his army melt away, and was happy to find that his brother’s moderation and love of peace was so great that he was allowed to retain his principality at Mesembria with the title of despot.
The deeds of Joannes (Janos) Hunyady might have awakened the Greeks from their lethargy, had any warlike spirit survived in the nation. The victory of the Hungarian army at the pass of Isladi, and a war with the sultan of Karamania, threatened the Ottoman Empire with serious danger; but the victory of Varna re-established the glory of the sultan’s arms. Neither the successes of the Hungarians nor the presence of a papal force in the Hellespont, which at last made its appearance under the command of Cardinal Gondolmieri, could induce Emperor Joannes to unite his cause with that of the western powers. He had obtained too many proofs of the instability and imprudence of their counsels. The moment he heard of the great victory of Sultan Murad at Varna, he sent an embassy to congratulate his suzerain, and solicit a renewal of their alliance, which the sultan immediately granted. Joannes even contrived to avoid taking part in the war carried on against the sultan by his brother Constantine in Greece, and succeeded in preserving uninterrupted peace until his death in 1448. During his inglorious reign of twenty-three years he never forgot that he was a vassal of the Ottoman Empire. He proved precisely the temporising manager of the state that circumstances required; and his pliancy averted, during his lifetime, the calamities which were ready to overwhelm the Greek Empire.
REIGN OF CONSTANTINE XIII (1448-1453 A.D.)
Constantine XIII, the last of the Greek emperors, was residing in his despotat at Sparta when his brother Joannes VII died. As he had been recently engaged in hostilities with the sultan, it was doubtful whether Murad would acknowledge him as emperor, and Demetrius availed himself of these doubts to make another attempt to occupy the throne. The deficiency of truth, honour, and patriotism among the Greek aristocracy during the last century of the Eastern Empire is almost without a parallel in history; but Demetrius was too well known and too generally despised to find a large party even in that worthless aristocracy disposed to espouse his cause, while Constantine, on the other hand, was known to possess both candour and energy, and was respected by all except the most bigoted among the orthodox Greeks.
[1451 A.D.]
Sultan Murad II died in February, 1451, after a prosperous reign of thirty years, and was succeeded by his son Muhammed II, who was only twenty-one years old. Muhammed II was a man of great ambition and great talents; he united with extraordinary activity and courage a degree of judgment rare in his high station, and still rarer at his early age.
The conquest of Constantinople was the first object of his ambition. It was by nature the capital of his dominions, and as long as it remained in the hands of the Greeks the Ottoman Empire lay open to the invasions of the western Christians. Having concluded a truce for three years with John Hunyady, the young sultan crossed over into Asia to suppress the hostile proceedings of Ibrahim, the sultan of Karamania.
Constantine, who appears to have formed a very erroneous idea of the talents and character of Muhammed, took this opportunity of insulting him in the most sensitive manner by sending an embassy to demand an augmentation of the pension of three hundred thousand aspers, which the Ottoman court had accorded to the Greek for the maintenance of Orkhan, the grandson of Suleiman. The ambassadors were instructed to insinuate that, if the demand were not granted, Orkhan might be allowed to lay claim to the Ottoman throne.
