Note 1 — Chapter V · THE SPREAD OF ISLAM AMONG THE CHRISTIANS OF SPAIN.
Reading edition
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 1683.1
