All Rabbanites and Karaites who live in European countries are the descendants of Abraham, Isaac and Yaakov, peace be upon them, from the tribes of Judah, Benjamin and the semi-tribe of Manasseh.

The rest of the Jews, the nine tribes and semi-tribe of Ephraim, who were expelled by the kings of Ashur, separated from the kingdom of Judah and resettled into various countries, all confess the same religion and faith as the Karaites.

Muslims believe that if they call us Çufut (Jew), they humiliate us, but it is not offensive to us. To the contrary, we are proud of this name, because it means that we belong to the house of Judah, which is very honoured by us.

The book Zekher Tzadikim  - Chapter 31 - hakham Mordechai ben Josef Sultanski

Karaite scholars are the best representatives of the people that have lost all political independence, live on someone else's territory and have even stopped speaking the language of their own forefathers (Hebrew).

It is considered a scientifically baseless statement that the Karaites are a residue of the Khazars, who settled in the fifth century near the Caspian Sea and the lower reaches of Volga and who ruled over Crimea, which was in a certain time called a Khazar name.

The proponents of this hypothesis strive to prove that (European) Karaites have not Semitic, but Turkic origin. This is how they explain the difference in appearance of the Karaites that do not match with the appearance of the Jews (rabbanites).

There is fact that supports the Semetic origin of the Karaites. It is still possible these days to find Levites and Kohens, the descendants of Aaron among the Karaites and they can only be found among people who are the descendants of the ancient Israelites.

The absence of any legend or oral tradition about the Khazars among the Karaites also serves as strong evidence that the Karaites are not descended from the Khazars.

It is impossible to believe that the whole nation has forgotten their own ancestors, even if the ancestors were so powerful that they were respected by the Byzantine emperors; it is not possible that the whole nation has forgotten that his ancestors owned the land where they live.

The Identification of the ((Crimean) Karaites) as the descendants of the Khazars is a very eccentric hypothesis.

Sixty or seventy years ago, the appearance of the (Crimean) Karaites only differed slightly from the appearance of the Tatars, only their racial phenotype, which was significantly different from the Mongolian phenotype of Tatars, revealed their other ethnicity.

In the present days the Crimean Karaites have replaced the language of the Tatars with the Russian language and young people, especially from the areas out of Crimea, do not understand the language of Tatars; even in the Crimea this language is only used by the poor and uncivilized families.

Let it be known to you, that we the residents of Crimea, belong to the tribes of Benjamin, Levi, and Judah, the expatriates from Jerusalem, who abandoned their towns to help their brothers in the war of Shomron, as it is written in the notes that were found in the town of Derbent and village of Madzhalis.
