From the eighth to the thirteenth centuries a number of new ethnic elements had entered Asia Minor. Except along the range of the Taurus and in the valleys of rivers which emptied into the Aegaean Sea, the Greek element, or more specifically, the Hellenic organization of imperial institutions, had gone back to the coast cities from which it had originally come. The progress of Moslem conquest, after driving before it into Asia Minor the more zealous and militant Armenian and Syrian Christians, had brought a considerable immigration, partly Syrian, partly Arab, and varying in faith. The earlier Turks, who came largely by way of Persia, with a period of settlement in that country, belonged to the great Seljuk movement. They were nominally Moslems, and very quickly became an indigenous element, because they had settled themselves permanently in every place that had been opened up to Turkish immigration by the Seljuk armies. So firmly rooted did they become that, when the fortunes of war allotted again temporarily some of the places which they inhabited to the Crusaders and to the Nicaean Byzantines, they did not dream of moving out. This was the best country they had ever seen and they had no intention of leaving it. When the Osmanlis captured Brusa and Nicaea, they found many Moslems who had been there for three generations. Simple-minded, tolerant of others, totally unconscious of the privileges as well as of the obligations of an organized society, the Turks of the earlier immigration neither opposed nor aided in the political changes which have so frequently been the lot of Asia Minor since their coming. This holds true of the Anatolian Turks of the present day, and will be so as long as they remain illiterate and uninstructed. In the first quarter of the thirteenth century there was another great migration towards Asia Minor, towards rather than into the peninsula, because it partly scattered itself in the mountains of Armenia and partly turned southward, going over the Taurus and Amanus ranges into Cilicia and Syria. Some got as far as Egypt. The earlier Seljuk invasion had been that of settlers following a victorious army. This invasion was that of refugees fleeing before a terrible foe. For Djenghiz Khan and his Mongol horde had come out of central Asia, and all who could, even the bravest, fled before him. The lesson had been quickly learned that to resist him meant certain death. Because it was a migration of families, with all their worldly possessions, and because they had to hurry and did not know where they were going, the great bulk of them did not advance far.[2]
