At the end of the book's last chapter, Koestler summarizes its content and his intentions as follows: "In Part One of this book I have attempted to trace the history of the Khazar Empire based on the scant existing sources. In Part Two, Chapters V-VII, I have compiled the historical evidence which indicates that the bulk of Eastern Jewry — and hence of world Jewry — is of Khazar-Turkish, rather than Semitic, origin. In the last chapter I have tried to show that the evidence from anthropology concurs with history in refuting the popular belief in a Jewish race descended from the biblical tribe."

Referencing ''The Thirteenth Tribe'', the study's authors note that "Some authors argue that after the fall of their kingdom in the second half of the 10th century CE, the Khazar converts were absorbed by the emerging Ashkenazi Jewish community in Eastern Europe." They conclude: "However, if the R-M17 chromosomes in Ashkenazi Jews do indeed represent the vestiges of the mysterious Khazars then, according to our data, this contribution was limited to either a single founder or a few closely related men, and does not exceed ~ 12% of the present-day Ashkenazim".
