The Osmanlis employ the word “Turk” when referring to a coarse and brutal man. According to the Osmanlis, the epithet Turk belongs only to the peoples of Turkestan and to those vagabond hordes who lead a stagnant life in the deserts of Khorassan. All the peoples submitted to the Empire are designated under the collective name of Osmanlis from Osman I, the founder of the Monarchy, and they do not understand why they are called Turks by Europeans. As they attach to this word the idea of the most marked insult, no foreigner in the Empire ever allows himself to use it in speaking to them.[98] The Osmanlis, as we have seen, were of mixed blood, even while still confined to Asia Minor. But after their conquests in Europe and further expansion in Asia they “became in blood the most cosmopolitan and vigorous race the world had known since the days of the Greeks and Romans. Greek, Turkish, Serbian, Bulgarian, Albanian, Armenian, Wallachian, Hungarian, German, Italian, Russian, Tartar, Mongol, Circassian, Georgian, Persian, Syrian, Arabian--this was the ancestry of the Osmanlis, who, under Solyman the Magnificent, made the whole world tremble. In richness of blood the only parallel to the Osmanlis in modern times is the present population of the United States and Canada.”[99] It would, indeed, require an ethnological analyst of superhuman power to determine the percentage of Osmanli blood in the present inhabitants of the western part of the Ottoman Empire.[100] Nor is this all. From the day of Orkhan and Murad I, the Osmanlis have been classed as raiders like the devastating hordes of Timur and Genghis Khan. Nothing could be farther from the truth. So far indeed were they from being a predatory people like the Mongols and Tartars that they were, from the days of their founder, a race of colonists and empire builders. This was the secret of their success and the explanation of the marvelous development of the Empire of the Sultans, which, as the eminent Austrian historian, Joseph Von Hammer-Purgstall, has declared “was more rapid in its rise than Rome, more enduring than that of Alexander.” The causes which contributed to the rapid development of the Osmanlis from the four hundred warriors of Osman into the vast armies of his successors and to the achievement of such extraordinary results in so short a period of time were, as the historian Finlay points out, “in some degree similar to those which had enabled small tribes of Goths and Germans to occupy and subdue the Western Roman Empire.”[101]
