We first hear of the Ottoman Turks at the commencement of the thirteenth century, when fleeing before the Mongols, to the number of about 50,000, they came to the help of the Sultan of Iconium, and in return for their services both against the Mongols and the Greeks, had assigned to them a district in the north-west of Asia Minor. This was the nucleus of the future Ottoman empire, which, increasing at first by the absorption of the petty states into which the Saljūq Turks had split up, afterwards crossed over into Europe, annexing kingdom after kingdom, until its victorious growth received a check before the gates of Vienna in 1683. [446] From the earliest days of the extension of their kingdom in Asia Minor, the Ottomans exercised authority over Christian subjects, but it was not until the ancient capital of the Eastern empire fell into their hands in 1453 that the relations between the Muslim Government and the Christian Church were definitely established on a fixed basis. One of the first steps taken by Muḥammad II, after the capture of Constantinople and the re-establishment of order in that city, was to secure the allegiance of the Christians, by proclaiming himself the protector of the Greek Church. Persecution of the Christians was strictly forbidden; a decree was granted to the newly elected patriarch which secured to him and his successors and the bishops under him, the enjoyment of the old privileges, revenues and exemptions enjoyed under the former rule.

The patriarch’s court sat to decide all cases between Greek and Greek: it could impose fines, imprison offenders in a prison provided for its own special use, and in some cases even condemn to capital punishment: while the ministers and officials of the government were directed to enforce its judgments. The complete control of spiritual and ecclesiastical matters (in which the Turkish government, unlike the civil power of the Byzantine empire, never interfered), was left entirely in his hands and those of the grand Synod which he could summon whenever he pleased; and hereby he could decide all matters of faith and dogma without fear of interference on the part of the state. As a recognised officer of the imperial government, he could do much for the alleviation of the oppressed, by bringing the acts of unjust governors to the notice of the Sultan. The Greek bishops in the provinces in their turn were treated with great consideration and were entrusted with so much
