Siberian Tatars or Sybyrs (Siberian Tatar: Сыбырлар, romanized: Sıbırlar) are the indigenous Turkic-speaking population of the forests and steppes of Western Siberia, originating in areas stretching from somewhat east of the Ural Mountains to the Yenisey River in Russia.

[4] The word "Tatar" or "Tadar" is also a self-designation by some closely related Siberian ethnic groups, namely the Altaians, Chulyms, Khakas, and Shors.

Siberian Tatars historically lived in the vast territory stretching from around the Yenisey River all the way to the area lying somewhat east of the Ural Mountains.

According to the ambassadors of the Siberian Khanate ruler Yediger Khan, who visited Moscow in 1555, the population of "the black people", not counting the aristocracy, was 30,700.

The Siberian Tatars tried to avoid the census as much as possible, as they believed that it was an attempt to force them to pay the Yasak (tribute).

[6] Like most of the modern indigenous human groups of West Siberia, Siberian Tatars reveal traits that are specific of West-Sibirid anthropological type.

[9] Siberian Tatars show a combination of features characteristic of both eastern and western Eurasians.

The term Siberian Tatar covers three autochthonous groups, all Sunni Muslims of the Hanafi madhab, found in southern Siberia.

Siberian Tatars' ancestry can be traced back to Turkic, Mongolic, Ket, Samoyedic and Ugric[10] tribes.

[11] Since the penetration of Islam until the 1920s after the Russian Revolution, Siberian Tatars, like all Muslim nations, were using an alphabet that had been based on Arabic script.

Teams have conducted scientific research in the field of literary language norms of the indigenous population of Siberia.

Traditional occupations of the Siberian Tatars included hunting, raising horses, and porterage (the latter being important because of the major trade routes situated within the region).

[13] Some traditional foods in Siberian Tatar cuisine include barley, kattama, boortsog, noodles, and peremech along with several dairy items like kaymak and qurut.

The Takhtamyshevo settlement: The most common is the haplogroup R1b1a1a2a2c1-CTS1843 (32%), which is widespread in the Volga and southern Urals region among Bashkirs, Kazan Tatars, Udmurts and Chuvash.

This is confirmed also from the anthropological perspective, as inhabitants of the Takhtamyshevo village show more Caucasoid physical features compared to the rest of Tom Tatars.

In this case it is not clear if this haplogroup has its origins with immigrant from the Urals or its a legacy of older local inhabitants.

This haplogroup is also represented in the other two villages of Takhtamyshevo (16%) and Eushta (20,6%), and is the marker of Turkic component in the gene pools of Tom Tatars.

Rare samples belong to haplogroups I1, I2a, J2a, J2b, which are connected with European and Central Asian immigrants to the region.

The presence of this haplogroup in the village of Eushta is probably the consequence of resettled Kalmak Tatars from the Kemerovo oblast.

The haplogroups of males of Eushta village show no evidence of mixing with Kazan Tatars and other immigrants from the European territory.

The closenes of genetic lines with Teleuts, Northern Altaians, Shors, Khakas and Tuvans tells us about the common legacy of the Turkic-speaking peoples of the Altai-Sayan region.

The Bukharlyks, literally "those from the city of Bukhara" are descendants of 15th- and 16th-century fur merchant colonies from Western Caucasus.
