Pressed on the one side by his Turkish neighbours and on the other by the danger of including in his dominions a large and unassimilated mass of Christians, Orkhan was wise enough to desist from any attempt at forcible conversion. But some modus vivendi had to be arranged. A mere raider would have massacred and destroyed, and the empire he built would not have outlived the century of its birth. Orkhan was neither raider nor invader. He lived in the country of his father and of his grandfather. Many of his lieutenants—certainly his ablest ones[141]—were descendants of the oldest stock in Asia Minor. His nation, if it was to be a nation, depended upon at least a partial assimilation of the Byzantines. As his dominions increased, it became clear that there had to be some distinction between Moslem and Christian other than a profession of faith. He must devise some reward, which would be so attractive that the Christians, especially the higher classes among them, would change their faith in order to secure its benefits. This was the problem.
Orkhan solved this problem by establishing a system of rewards for military service, and then by restricting military service to Moslems. He divided the land he had conquered among his faithful warriors, and let it be known that in future conquests a large portion of the territory won, outside of the cities, would be bestowed upon soldiers who took part in his campaigns. These lands were to be held as military fiefs. The only obligation was that of military service, which could be performed either by actually putting into the field a number of men in proportion to the land held or by paying a sum sufficient to replace the quota by hired troops. So far this was but an adaptation of the European feudal system. But it was superior to the European system in that the holdings were small and that there was through two centuries an ever-present opportunity of winning new holdings.
Except in Albania and Bosnia, where the old nobility were to preserve their lands by conversion to Islam, there were no local traditions to prevent such a scheme by necessitating the dispossession of former great landowners. The Seljuks, the Crusaders, and the Mongols in Asia Minor, the Catalans, the Bulgarians, the Serbians and the civil wars between the emperors in Macedonia and Thrace, the hangers-on of the Fourth Crusade in Thessaly, Greece, and the Aegaean Islands, had made so clean a sweep of the old aristocracy, attached to the soil, that Orkhan’s idea was feasible. Through these small holdings and through the rapid increase of conquered territory, the Ottoman sultans were able, almost from the beginning, to exercise an absolute sovereignty over their expanding dominions, and to prevent the rise of a class of nobles. The Ottoman Empire has never known an hereditary nobility. In the later conquests, the Sublime Porte sometimes granted life rights of governorship, with a tacit understanding that the succession should go to the son, to local chieftains or to large landowners. But these concessions were in regions never fully conquered, and remote from Constantinople. Those to whom these privileges were given had no part in the central government and no rank outside of their immediate locality.
In place of military service, every adult Christian paid a special head-tax, to be used for the support of the army. The Christian was exempt from military service; the Mussulman was exempt from taxes.[142] This head-tax was heavy, and so gauged as to keep the Christian, unless he lived in a city, in economic dependence upon the Moslem landowner. As a general rule, during the first century and a half of Ottoman conquest, those who held to the old faith went to the cities and large towns. The Moslem thus became, without any attempt at forcible conversion or need to massacre, the undisputed possessor of the country districts.
Aside from the onerous head-tax, there were grave inequalities for the Christian in matters of law and in intermarriage. After the fall of Constantinople, Mohammed the Conqueror gave the Christians a large measure of self-government by putting them in millets (nations) under the headship of the ecclesiastical authorities. But the inequality in the matter of intermarriage has never been done away with. A Moslem may marry a Christian woman, but a Christian is forbidden to marry a Mohammedan woman. In the earliest days, when there was neither racial nor religious antipathy and Christian and Moslem lived in close social intercourse, this law was a powerful proselytizing agency. It furnished a temptation to a change of faith which, whenever it arose, was far stronger than the temptation of lands, of power, of economic independence, or of civil equality.
The moment one professed Islam he became an Osmanli. Religion has always been the test of nationality in the Ottoman Empire.[143] The Osmanlis increased from the thousands to the millions, in Macedonia, in Thrace, and in Asia Minor. Ancestry was quickly forgotten in the midst of ever-changing conditions and the founding of a new social order. It is still a characteristic of the Osmanli that he has no surname. The most widely-read English writer of the seventeenth century on the ‘Turks’ emphasized the mixture of blood in the Osmanli, when he wrote: ‘At present the blood of the Turks is so mixed with that of all sorts of Languages and Nations, that none of them can derive his Lineage from the ancient blood of the Saracens.’[144]
A majority of the Byzantines whom Orkhan, Murad, and Bayezid conquered must have become Osmanlis. Once the change of religion was made, the development of the new race was not difficult. There was much in common between the Turk of Asia Minor and the Byzantine. An Armenian contemporary wrote of them as if they were alike.[145] The Greeks did not take to heart the new régime,[146] for the fiscal evils of the Byzantine system reconciled them in advance to a change. Nothing could be worse than that which they had suffered.[147]
Of course, the love of woman, the desire for adventure, hope of economic independence through rewards of land and removal of onerous taxes, disgust with the Byzantine administration and with the lack of support from their rulers and ecclesiastical authorities—these influences did not cause the conversion of all the Christians. In the cities, where the inequality and the inconvenience of remaining true to the old faith was minimized, and where Christianity has always been able to make itself felt and heard,[148] there was no great temptation to a change of religion. After the Osmanlis became stronger, and entered into the aggressive period of conquest, they resorted to other means to swell their numbers. The institution of the Janissaries, and the permission to enslave those whom they conquered, gave the Osmanlis more potent and immediately pressing arguments.
From the completion of the conquest of Bithynia by Orkhan, the Osmanlis can be called a distinct race with a national consciousness and a desire for expansion. They can be distinguished from the Turks of the emirates of Asia Minor and from the Byzantines. The Turk did not absorb the Greek, nor did the Greek absorb the Turk. Both had taken a new religion, and if the Turkish language was adopted, it was rather the customs and laws of the Byzantines which prevailed until the influence of the Arabs, enhanced as it was with the prestige of centuries of Islam, gained the ascendancy over Turkish and Byzantine tradition alike. But this did not occur until the Osmanlis invaded Syria, Egypt, and Mesopotamia at the beginning of the sixteenth century.
It must be remembered that the Greeks were not the only element added to the Turkish stock. The adoption of the Turkish language by the Osmanlis was due not only to the fact that from the beginning it was the military and governmental language, but to its being the simplest and most vigorous medium of communication for the different peoples who became Osmanlis.
