The Turkish language was brought in by immigrants from Central Asia after the Byzantine defeat in the battle of Manzikert in 1071, but the modern Turks are probably a mixture of Central Asians and those who were there before (Lydians, Cappadocians, Galatians, etc.) and those who were brought in as slaves during Ottoman times. As late as the early 1800s Turks were raiding coastal areas of the Mediterranean and carrying peasants off as slaves.
The modern Turkish language was created by an Armenian after WWI. They did not discuss that fact that he was Armenian.

I have no Armenian, Turk, Kurd or Arab ancestry.
But I have posted a lot of articles here about them over past 5 years. It has been an education.
I do have many friends in the region. And I have learned to trust those who are always truthful with me.
