"At the present time we know of no nation under the heavens where Christians do not live. For [Christians are even found] in the lands of Gog and Magog -- who are a Hunnic race and are called Gazari (Khazars)... circumcized and observing all [the laws of] Judaism. The Bulgars, however, who are of the same seven tribes [as the Khazars], are now becoming baptized [into Christianity]." - Christian of Stavelot, in
Expositio in Matthaeum Evangelistam, composed circa 864
"Thus, it is clear that the false doctrine of Jesus in Rome, that of Moses among the Khazars, [and] that of Mani in [Uyghur-ruled] Turkistan removed the strength and bravery that they formerly possessed..." -
Denkart, a Persian work
"All of the Khazars are Jews. But they have been Judaized recently." - Ibn al-Faqih, a 10th century author
"One of the Jews undertook the conversion of the Khazars, who are composed of many peoples, and they were converted by him and joined his religion. This happened recently in the days of the Abbasids.... For this was a man who came single-handedly to a king of great rank and to a very spirited people, and they were converted by him without any recourse to violence and the sword. And they took upon themselves the difficult obligations enjoined by the law of the Torah, such as circumcision, the ritual ablutions, washing after a discharge of the semen, the prohibition of work on the Sabbath and during the feasts, the prohibition of eating the flesh of forbidden animals according to this religion, and so on." - Abd al-Jabbar ibn Muhammad al-Hamdani, in his early 11th century work

The Karaite writer Jacob ben Reuben referred to the Khazars in
Sefer ha-Osher as "a single nation who do not bear the yoke of the exile, but are great warriors paying no tribute to the Gentiles."
"The Khazar Jews came to the court of Prince Vladimir and said: 'We have heard that Bulgarians (Muslims) and Christians came to teach you their religion... We, however, believe in the one God of Abraham, Isaac, and Jacob.' Vladimir asked them: 'What kind of law do you have?' They answered: 'We are required to be circumcized, we may not eat pork or hare meat, and we must observe the Sabbath.' And he asked: 'Where is your land?' They answered: 'In Jerusalem.' And again he asked: 'It is really there?' They answered: 'God got angry with our fathers and therefore scattered us all over the world and gave our land to the Christians.' Vladimir asked: 'How is it that you can teach people Jewish law even while God rejected you and scattered you. If God had loved you and your law, you would not be scattered throughout foreign lands. Or do you wish us Rus'ians to suffer the same fate?'" - The Russian Chronicle, describing a visit of Khazar missionaries to Kiev in the year 986
"The king and his vizier travelled to the deserted mountains on the seashore, and arrived one night at the cave in which some Jews used to celebrate the Sabbath. They disclosed their identity to them, embraced their religion, were circumcized in the cave, and then returned to their country, eager to learn the Jewish law. They kept their conversion secret, however, until they found an opportunity of disclosing the fact gradually to a few of their special friends. When the number had increased, they made the affair public, and induced the rest of the Khazars to embrace the Jewish faith. They sent to various countries for scholars and books, and studied the Torah. Their chronicles also tell of their prosperity, how they beat their foes, conquered their lands, secured great treasures, how their army swelled to hundreds of thousands, how they loved their faith, and fostered such love for the Holy House that they erected a tabernacle in the shape of that built by Moses. They also honored and cherished the Israelites who lived among them." -

"The Khazars have a script which is related to the script of the Russians [Rus].... The greater part of these Khazars who use this script are Jews." -

Khazaria is regarded as the "country of the Jews" (
Zemlya Zhidovskaya) in Russian folk literature (
byliny). And the
Schechter Letter informs us that some of the Alan people (neighbors of the Khazars to the south) also adopted Judaism (see Golb and Pritsak,
Khazarian Hebrew Documents of the Tenth Century, pages 113 and 115).
