"The word tribe is as troublesome as the term clan. It is commonly held to denote a group, like the clan, claiming descent from a common (in some culture zones eponymous) ancestor, possessing a common territory, economy, language, culture, religion, and sense of identity. In reality, tribes were often highly fluid sociopolitical structures, arising as 'ad hoc responses to ephemeral situations of competition,' as Morton H. Fried has noted."

Whittow states that the word Türk had no strict ethnic meaning at the time: "Throughout the early middle ages on the Eurasian steppes, the term 'Turk' may or may not imply membership of the ethnic group of Turkic peoples, but it does always mean at least some awareness and acceptance of the traditions and ideology of the Gök Türk empire, and a share, however distant, in the political and cultural inheritance of that state."

Several scholars connect it to Judaization, with Artamonov linking its introduction to Obadiyah's reforms and the imposition of full Rabbinical Judaism and Pritsak to the same period (799–833), arguing that the Beg, a majordomo from the Iranian *Barč/Warâ Bolčan clan, identified with Obadiyah, compelled the Qağanal clan to convert, an event which putatively caused the Qabar revolt. Golden comments: "There is nothing but conjecture to connect it with the reforms of Obadiyah, the further evolution of Khazar Judaism or the Qabars ... The fact is we do not know when, precisely, the Khazar system of dual kingship emerged. It could not have come ex nihilo. It was not present in the early stages of Khazar history. Given the Old Türk traditions of the Khazar state ... and the overall institutional conservation of steppe society, one must exercise great caution here. Clear evidence for it is relatively late (the latter part of the ninth century perhaps and more probably the tenth century)- although it was probably present by the first third of the ninth century. Iranian influences via the Ors guard of the Qağans may have also been a factor" (Golden 2007b, pp. 155–156) Golden, Peter Benjamin (2007b). "The Conversion of the Khazars to Judaism".

Theophanes the Confessor around 813 defined them as Eastern Turks. The designation is complex and Róna-Tas writes: "The Georgian Chronicle refers to the Khazars in 626–628 as the 'West Turks' who were then opposed to the East Turks of Central Asia. Shortly after 679 the Armenian Geography mentions the Turks together with the Khazars; this may be the first record of the Magyars. Around 813, Theophanes uses – alongside the generic name Turk – 'East Turk' for the designation of the Khazars, and in context, the 'West Turks' may actually have meant the Magyars. We know that Nicholas Misticus referred to the Magyars as 'West Turks' in 924/925. In the 9th century the name Turk was mainly used to designate the Khazars."

"The Khazars, the close allies of the Byzantines, adopted Judaism, as their official religion, apparently by 740, three years after an invasion by the Arabs under Marwan ibn Muhammad. Marwan had used treachery against a Khazar envoy in order to gain peaceful entrance into Khazar territory. He then declared his dishonourable intentions and pressed deep into Khazar territory, subsequently, he released the envoy. The Arabs devastated the horse herds, seized many Khazars and others as captives, and forced much of the population to flee into the Ural Mountains. Marwan's terms dictated that the kaghan and his Khazars should convert to Islam. Having no choice, the kaghan accepted Marwan's terms, and the Arabs returned home in triumph. As soon as the Arabs were gone, the kaghan renounced Islam – with, one may assume, great vehemence. The Khazar Dynasty's conversion to Judaism is best explained by this specific historical background, together with the fact that the mid-eighth century was an age in which the major Eurasian states proclaimed their adherence to distinctive world religions. Adopting Judaism also was politically astute: it meant that the Khazars did not have to accept the overlordship (however theoretical) of the Arab caliph or the Byzantine emperor."

Some sources claim that the father of Seljuk, the eponymous progenitor of the Seljuk Turks, namely Toqaq Temür Yalığ, began his career as an Oghuz soldier in Khazar service in the early and mid-10th century, and rose to high rank before he fell out with the Khazar rulers and departed for Khwarazm. Seljuk's sons, significantly, all bear names from the Jewish scriptures: Mîkâ"il, Isrâ"îl, Mûsâ, Yûnus. Peacock argues that early traditions attesting a Seljuk origin within the Khazar empire when it was powerful, were later rewritten, after Khazaria fell from power in the 11th century, to blank out the connection (Peacock 2010, pp. 27–35).

"If anyone thinks that the Khazar correspondence was first composed in 1577 and published in Qol Mebasser, the onus of proof is certainly on him.

"Arthur Koestler's book The Thirteenth Tribe which claimed that the converted Khazars were the progenitors of today's Ashkenazi Jews, has largely been rejected by serious scholars. However, the disputed theory that the stereotypical European Jew is descended from an Eastern European nation of Jewish converts, has been sufficiently unwelcome as to render study of the Khazars an area of research largely off limits for Jewish as well as Russian archaeologists, the Russians being unhappy with the prospect that their empire was initially ruled by Jewish kings, and the Jews being unhappy with the prospect that the Ashkenazim might not have a genetic connection to the freed slaves who met with God at Sinai."

"By the 1960s, when Christian identity was established as a force on the extreme right, the Khazar ancestry of the Jews was a firm article of faith. Two books, written in this milieu and widely read, came to exercise a strong influence in this regard. John Beaty's Iron Curtain over America (1951) and Wilmot Robertson's Dispossessed Majority (1972) repeated the Khazar thesis of Stoddard. Christian identity teachings readily seized on this negative reference to Russian Jewry, however, it backdated the history of intermarriage between Jews and Khazars to biblical times. In A Short History of Esau-Edom in Jewry (1948), the Vancouver-based writer C.F. Parker claimed that a tiny remnant of 'true Judah' was pitted against a large group of Idumean-Hittites who masqueraded as the true seed of Abraham and sought to expel the descendants of Jacob.

"During Greco-Roman times, recorded mass conversions led to 6 million people practicing Judaism in Roman times or up to 10% of the population of the Roman Empire. Thus, the genetic proximity of these European/Syrian Jewish populations, including Ashkenazi Jews, to each other and to French, Northern Italian, and Sardinian populations favors the idea of non-Semitic Mediterranean ancestry in the formation of the European/Syrian Jewish groups and is incompatible with theories that Ashkenazi Jews are for the most part the direct lineal descendants of converted Khazars or Slavs. The genetic proximity of Ashkenazi Jews to southern European populations has been observed in several other recent studies.. Admixture with local populations, including Khazars and Slavs, may have occurred subsequently during the 1000 year (2nd millennium) history of the European Jews.

"During Greco-Roman times, recorded mass conversions led to 6 million people practicing Judaism in Roman times or up to 10% of the population of the Roman Empire. Thus, the genetic proximity of these European/Syrian Jewish populations, including Ashkenazi Jews, to each other and to French, Northern Italian, and Sardinian populations favors the idea of non-Semitic Mediterranean ancestry in the formation of the European/Syrian Jewish groups and is incompatible with theories that Ashkenazi Jews are for the most part the direct lineal descendants of converted Khazars or Slavs. The genetic proximity of Ashkenazi Jews to southern European populations has been observed in several other recent studies.. Admixture with local populations, including Khazars and Slavs, may have occurred subsequently during the 1000 year (2nd millennium) history of the European Jews. Based on analysis of Y chromosomal polymorphisms, Hammer estimated that the rate might have been as high as 0.5% per generation or 12.5% cumulatively (a figure derived from Motulsky), although this calculation might have underestimated the influx of European Y chromosomes during the initial formation of European Jewry.15 Notably, up to 50% of Ashkenazi Jewish Y chromosomal haplogroups (E3b, G, J1, and Q) are of Middle Eastern origin, 15 whereas the other prevalent haplogroups (J2, R1a1, R1b) may be representative of the early European admixture.20 The 7.5% prevalence of the R1a1 haplogroup among Ashkenazi Jews has been interpreted as a possible marker for Slavic or Khazar admixture because this haplogroup is very common among Ukrainians (where it was thought to have originated), Russians, and Sorbs, as well as among Central Asian populations, although the admixture may have occurred with Ukrainians, Poles, or Russians, rather than Khazars."

Olsson writes that there is no evidence for this Islamic guard for the 9th century, but that its existence is attested for 913 (Olsson 2013, p. 507). Olsson, Joshua T. (2013).

Al-Mas'udi says the king secretly tipped off the Rus' of the attack but was unable to oppose the request of his guards (Olsson 2013, p. 507). Olsson, Joshua T. (2013).

"scholars who have contributed to the subject of the Khazars' conversion, have based their arguments on a limited corpus of textual, and more recently, numismatic evidence ... Taken together these sources offer a cacophony of distortions, contradictions, vested interests, and anomalies in some areas, and nothing but silence in others."

The idea of a forced general conversion imposed on the Qağanal dynasty in the 830s was advanced by Omeljian Pritsak, and is now supported by Roman Kovalev and Peter Golden (Olsson 2013, p. 497).

Olsson identifies this with the onset of Magyar invasions of the Pontic steppe in the 830s, the construction of Sarkel, and the Schechter letter's reference to Bulan, converted to his Jewish wife Serakh's faith, wresting power, in a period of famine, elements which undermined the qağan, and allowed the creation of the royal diarchy (Olsson 2013, pp. 507, 513ff).

Noonan gives the lower figure for the Muslim contingents, but adds that the army could draw on other mercenaries stationed in the capital, Rūs, Ṣaqāliba and pagans. Olsson's 10,000 refers to the spring-summer horsemen in the nomadic king's retinue (Noonan 2007, pp. 211, 217). Noonan, Thomas S. (2007). "The Economy of the Khazar Khaganate".

"Engravings that resemble the six-pointed Star of David were found on circular Khazar relics and bronze mirrors from Sarkel and Khazarian grave fields in Upper Saltov. However, rather than having been made by Jews, these appear to be shamanistic sun discs." (Brook 2010, pp. 113, 122–123 n.148) Brook, Kevin Alan (2010) [First published 1999].

Brook says this thesis was developed by Jacob Mann, based on a reading of the word "Khazaria" in the Cairo Geniza fragment. Bernard Lewis, he adds, challenged the assumption by noting that the original text reads Hakkâri and refers to the Kurds of the Hakkâri mountains in south-east Turkey (Brook 2010, pp. 191–192, n.72).

"There were Arab tribes who were Jews in the time of Muhammad, and a Turkic people who were mainly Jews in South Russia in the ninth century. Judaism is indeed the reconstructed political ideal of many shattered peoples-mainly semitic. As a result of these coalescences and assimilations, almost everywhere in the towns throughout the Roman Empire, and far beyond it in the east, Jewish communities traded and flourished, and they were kept in touch through the Bible, and through a religious and educational organization. The main part of Jewry never was in Judea and it had never come out of Judea." (Wells 1920, p. 570) Wells, H. G. (1920). The Outline of History: Being a Plain History of Life and Mankind. Vol. 1.
