Certainly commentators at the time, one thousand years ago, thought that a new people was arriving.
Well, you see, you just don't get it. Those Chronicles from the period of 1070-1100 were rewritten much later after 1700 by lying Greek Nationalist Monks on Mt Athos who made up the history out of wholecloth about the Turkish invasion.
In reality, "bloodthirsty cuthroat Greeks" tried to invade the "God-loving peaceful Turkish Sheepherders" at that time, trying to drive them from their ancestoral homeland of 3000 years, and the "noble, peace-loving Turks" repulsed them and sent them home with their tails between their legs. In order to avoid the embarassment of this defeat, the "accursed lying Greeks" transmorgified the story of their barbaric invasion of the "beuatiful chaste chosen people Turks" into Homer's story the "Illiad", and pretended it actually happened 1800 year earlier. Then the "wicked decietful Greeks" went and planted all sorts of archaeological items during secret night raids in their boats, and made up tall tales to circulate in Germany and England to inspire romantic Archaeologists to go and dig up their secretly hidden Archaelogical frauds. But note well, since they had to plant them in boats, the "Devil's spawn children of hell Greeks" could only plant their falsehoods near the shores of the Black and Medditerranean Seas, which is why people think there is evidence of Greek settlement on the coasts right up to the early part of last century. The "cruel baby muderer Greeks" will stop at nothing in their campaign of deceit and hatred to displace the "Turkish children of God" from their homeland in Anatolia.
But now the TRUTH is out.
