Shah was drowned in the passage of the Euphrates: his son Orthogrul became the soldier and subject of Aladin, and established at Surgut, on the banks of the Sangar, a camp of four hundred families or tents, whom he governed fifty-two years both in peace and war. He was the father of Thaman, or Athman, whose Turkish name has been melted into the appellation of the caliph Othman; and if we describe that pastoral chief as a shepherd and a robber, we must separate from those characters all idea of ignominy and baseness. Othman possessed, and perhaps surpassed, the ordinary virtues of a soldier; and the circumstances of time and place were propitious to his independence and success. The Seljukian dynasty was no more; and the distance and decline of the Mogul khans soon enfranchised him from the control of a superior. He was situate on the verge of the Greek empire: the Koran sanctified his gazi, or holy war, against the infidels; and their political errors unlocked the passes of Mount Olympus, and invited him to descend into the plains of Bithynia. Till the reign of Palæologus, these passes had been vigilantly guarded by the militia of the country, who were repaid by their own safety and an exemption from taxes. The emperor abolished their privilege and assumed their office; but the tribute was rigorously collected, the custody of the passes was neglected, and the hardy mountaineers degenerated into a trembling crowd of peasants without spirit or discipline. It was on the twenty-seventh of July, in the year twelve hundred and ninety-nine of the Christian æra, that Othman first invaded the territory of Nicomedia;⁷ and the singular accuracy of the date seems to disclose some foresight of the rapid and destructive growth of the monster. The annals of the twenty-seven years of his reign would exhibit a repetition of the same inroads; and his hereditary troops were multiplied in each campaign by the accession of captives and volunteers. Instead of retreating to the hills, he maintained the most useful and defensive posts; fortified the towns and castles which he had first pillaged; and renounced the pastoral life for the baths and palaces of his infant capitals. But it was not till Othman was oppressed by age and infirmities, that he received the welcome news of the conquest of Prusa, which had been surrendered by famine or treachery to the arms of his son Orchan. The glory of Othman is chiefly founded on that of his descendants; but the Turks have transcribed or composed a royal testament of his last counsels of justice and moderation.⁸

From the conquest of Prusa, we may date the true æra of the Ottoman empire. The lives and possessions of the Christian subjects were redeemed by a tribute or ransom of thirty thousand crowns of gold; and the city, by the labors of Orchan, assumed the aspect of a Mahometan capital; Prusa was decorated with a mosque, a college, and a hospital, of royal foundation; the Seljukian coin was changed for the name and impression of the new dynasty: and the most skilful professors, of human and divine knowledge, attracted the Persian and Arabian students from the ancient schools of Oriental learning. The office of vizier was instituted for Aladin, the brother of Orchan;⁹ and a different habit distinguished the citizens from the peasants, the Moslems from the infidels. All the troops of Othman had consisted of loose squadrons of Turkman cavalry; who served without pay and fought without discipline: but a regular body of infantry was first established and trained by the prudence of his son. A great number of volunteers was enrolled with a small stipend, but with the permission of living at home, unless they were summoned to the field: their rude manners, and seditious temper, disposed Orchan to educate his young captives as his soldiers and those of the prophet; but the Turkish peasants were still allowed to mount on horseback, and follow his standard, with the appellation and the hopes of freebooters.¹⁰ By these arts he formed an army of twenty-five thousand Moslems: a train of battering engines was framed for the use of sieges; and the first successful experiment was made on the cities of Nice and Nicomedia. Orchan granted a safe-conduct to all who were desirous of departing with their families and effects; but the widows of the slain were given in marriage to the conquerors; and the sacrilegious plunder, the books, the vases, and the images, were sold or ransomed at Constantinople. The emperor Andronicus the Younger was vanquished and wounded by the son of Othman:¹¹¹² he subdued the whole province or kingdom of Bithynia, as far as the shores of the Bosphorus and Hellespont; and the Christians confessed the justice and clemency of a reign which claimed the voluntary attachment of the Turks of Asia. Yet Orchan was content with the modest title of emir; and in the list of his compeers, the princes of Roum or Anatolia,¹³ his military forces were surpassed by the emirs of Ghermian and Caramania, each of whom could bring into the field an army of forty thousand men. Their domains were situate in the heart of the Seljukian kingdom; but the holy warriors, though of inferior note, who formed new principalities on the Greek empire, are more conspicuous in the light of history.
