Towards the middle of the thirteenth century a small band or tribe of nomad Turks migrated from Khorassan, in Central Asia, into Asia Minor. They were part of a much larger body, variously estimated at from two to four thousand horsemen, who, with their families, had fled from their homes in Khorassan under Solyman Shah. They had been driven thence by an invading horde of Mongols from farther east. They hoped to find asylum in Asia Minor. They crossed into Armenia and spent some years in the neighbourhood of Erzerum, plundering the natives there. When the wave of Mongols had spent its force, they proposed to return to Khorassan. On reaching the Euphrates River Solyman, when trying, on horseback, to find a ford, was carried away by the current and drowned. This was reckoned as a bad omen by many of his followers. Two of his sons, with a majority of them, either returned to Central Asia or dispersed on the way there... Other remnants of it survived under independent Emirs at Karamania, Sarukhan, Mentsche, and numerous other smaller States. Between them they possessed nearly the whole of Asia Minor, with the exception of a few cities in its north-west, such as Brusa, Nicæa, and Nicomedia and the districts round them, and a belt of territory along the Bosphorus, the Sea of Marmora, and the Hellespont, to which the Byzantine Emperors, formerly the owners of nearly the whole of Anatolia, were now reduced. Two small Christian States also still existed there—Trebizond, in the north-east, and Little Armenia, in Cilicia, in the south-east. Though divided among many independent Emirs, the people of Asia Minor, with the exception of the Greeks and Armenians, were fairly welded together. The invading Turks had intermixed with the native population, imposing on them the Turkish language, and had themselves adopted the religion of Islam. Ertoghrul and his nomad tribe, before entering this country, were not Moslems, but they were not strangers in language. Whatever their religion, it was held lightly. They were converted to Islam after a short stay in the country and, as is often the case with neophytes, became ardent professors of their new faith...
