Iskander was the youngest son of the Prince of Epirus, who, with the other Grecian princes, had, at the commencement of the reign of Amurath the Second, in vain resisted the progress of the Turkish arms in Europe. The Prince of Epirus had obtained peace by yielding his four sons as hostages to the Turkish sovereign, who engaged that they should be educated in all the accomplishments of their rank, and with a due deference to their faith. On the death of the Prince of Epirus, however, Amurath could not resist the opportunity that then offered itself of adding to his empire the rich principality he had long coveted. A Turkish force instantly marched into Epirus, and seized upon Croia, the capital city, and the children of its late ruler were doomed to death. The beauty, talents, and valour of the youngest son, saved him, however, from the fate of his poisoned brothers. Iskander was educated at Adrianople, in the Moslemin faith, and as he, at a very early age, exceeded in feats of arms all the Moslemin warriors, he became a prime favourite of the Sultan, and speedily rose in his service to the highest rank. At this period the irresistible progress of the Turkish arms was the subject of alarm throughout all Christendom. Constantinople, then the capital of the Greek Empire, had already been more than once besieged by the predecessors of Amurath, and had only been preserved by fortunate accidents and humiliating terms. The despots of Bosnia, Servia, and Bulgaria, and the Grecian princes of Etolia, Macedon, Epirus, Athens, Phocis, Boeotia, and indeed of all the regions to the straits of Corinth, were tributaries to Amurath, and the rest of Europe was only preserved from his grasp by the valour of the Hungarians and the Poles, whom a fortunate alliance had now united under the sovereignty of Uladislaus, who, incited by the pious eloquence of the cardinal of St. Angelo, the legate of the Pope, and, yielding to the tears and supplications of the despot of Servia, had, at the time our story opens, quitted Buda, at the head of an immense army, crossed the Danube, and, joining his valiant viceroy, the famous John Hunniades, vaivode of Transylvania, defeated the Turks with great slaughter, relieved all Bulgaria, and pushed on to the base of Mount Hæmus, known in modern times as the celebrated Balkan. Here the Turkish general, Karam Bey, awaited the Christians, and hither to his assistance was Iskander commanded to repair at the head of a body of Janissaries, who had accompanied him to Greece, and the tributary Epirots.
