The Kyrgyz are a
Turkic ethnic group. It has been suggested Turkic peoples either descended from pastoralist or farming populations in
Altaic (re-labelled as Transeurasian) hypothesis, and the Altaic hypothesis has been widely rejected.
Turkic urheimat has been suggested to be placed somewhere between
Transcaspian Steppe and
Manchuria;
Amur or
Northeast China also are amongst the suggestions along with
South Siberia. By the early 1st millennium BC, these peoples had become
equestrian nomads. In subsequent centuries, the steppe populations of
Central Asia appear to have been progressively
Turkified by an
East Asian dominant minority moving out of Mongolia. The oldest notes about a definite mention of the Kyrgyz ethnonym originate from the 6th century. The Kyrgyz as an ethnic group are mentioned quite unambiguously during the time of
Genghis Khan's rule (1162–1227), when their name replaces the former name Khakas. 18th-century Qing administrators referred to the Kyrgyz by the name
Bulute.
Possible Yenisei Kyrgyz affiliation The
Yenisei Kyrgyz, whose 9–10th century migration to the
Tienshan area was of "particularly great importance for the formative process" of the modern Kyrgyz, have their origins in the western parts of modern-day
Mongolia and first appear in written records in the Chinese annals of the
Sima Qian's
Records of the Grand Historian (compiled 109–91 BCE) as
Gekun (, ) or
Jiankun (). The Middle Age Chinese composition
Tang Huiyao of the 8–10th century transcribed the name "Kyrgyz" as
Jiegu (Kirgut), and their
tamga was depicted as identical to the tamga of the present-day Kyrgyz tribes Azyk, Bugu, Cherik, Sary Bagysh and a few others. The description of the Yenisei Kyrgyz as "large, with red hair, white faces, and green or blue eyes" in the
New Book of Tang (11th century) have tempted a number of researchers to assume that the Kyrgyz may have originally been non-Turkic or at least an ethnically mixed people with a large non-Turkic element. The
New Book of Tang did not consider the Yenisei Kyrgyz to be the same as the
Tiele people, but states that they had the same language and script as the
Uyghurs, who were part of the Tiele tribes. The Yenisei Kyrgyz were described to look similar to the neighboring "Boma tribe" (
Basmyl), who did not share the same language, implying that the Yenisei Kyrgyz may have originally been a non-Turkic people. According to the
You yang za zu by Duan Chengshi in the 9th century AD, the Yenisei Kyrgyz were not of wolf descent, unlike the
Türks, but were born in a cave north of the Quman Mountain as the offspring of a god and a cow. Based on these historical descriptions, Lee & Kuang suggest that the Yenisei Kyrgyz were turcophone, but may have been of non-Turkic origin, and were
Turkified through inter-tribal marriage. Contemporary Persian writer
Gardizi recounted a legend that ascribed these traits to
Saqaliba ancestry in the tribe. In 840, a revolt led by the Yenisei Kyrgyz brought down the Uyghur Khaganate, and brought the Yenisei Kyrgyz to a dominating position in the former
Second Turkic Khaganate. With the rise to power, the center of the Kyrgyz Khaganate moved to
Jeti-su, and brought about a spread south of the Kyrgyz to
Tian Shan and
Xinjiang, bringing them into contact with the existing peoples of what is now
Western China, especially the
Tibetan Empire. The
Khagans of the Yenisei Kirghiz Khaganate claimed descent from the Han Chinese general
Li Ling, which was mentioned in the diplomatic correspondence between the Kirghiz khagan and the
Tang dynasty emperor, since the Tang imperial Li family claimed descent from Li Ling's grandfather,
Li Guang. The Kirghiz qaghan assisted the Tang dynasty in destroying the Uyghur Khaganate and rescuing the
Princess Taihe from the
Uyghurs. They also killed a Uyghur khagan in the process. Then Kyrgyz quickly moved as far as the
Tian Shan range and maintained their dominance over this territory for about 200 years. In the 12th century, however, Kyrgyz domination had shrunk to the
Altai and
Sayan Mountains as a result of
Mongol expansion. With the rise of the
Mongol Empire in the 13th century, the Kyrgyz migrated south. In 1207, after the establishment of
Yekhe Mongol Ulus (Mongol empire), Genghis Khan's oldest son
Jochi occupied Kyrgyzstan without resistance. The state remained a Mongol vassal until the late 14th century. Various
Turkic peoples ruled them until 1685, when they came under the control of the
Oirats (
Dzungars), which lasted until
1757. Many Kyrgyz tribes that had fled the Dzungars returned to modern Kyrgyzstan at this time. By the 16th century, the carriers of the ethnonym
Kirgiz lived in South
Siberia, Xinjiang, Tian Shan,
Pamir-Alay,
Middle Asia,
Urals (among
Bashkirs), and in
Kazakhstan. In the Tian Shan and Xinjiang area, the term
Kyrgyz retained its unifying political designation, and became a general ethnonym for the Yenisei Kirgiz and other Turkic tribes that presently constitute the Kyrgyz population. Though it is impossible to directly identify the
Yenisei and
Tien Shan Kyrgyz, a trace of their ethnogenetical connections is apparent in archaeology, history, language and ethnography. A majority of modern researchers came to the conclusion that the ancestors of Kyrgyz tribes had their origin in the most ancient tribal unions of
Sakas/
Scythians,
Wusun/
Issedones,
Dingling,
Mongols, and
Huns.
Genetics in the
Barskoon valley Haplogroups The genetic makeup of the Kyrgyz is consistent with their origin as a mix of tribes. For instance, 63% of modern Kyrgyz men of
Jumgal District belong to the paternal
haplogroup R1a1. Low diversity of Kyrgyz R1a1 indicates a
founder effect within the historical period. Other groups of Kyrgyz especially Southwest Kyrgyz show a considerably lower frequency of haplogroup R. The other main haplogroups of modern Kyrgyz are
haplogroup C-M217 at 12–20%,
haplogroup O-M175 at 0–15%, and
haplogroup N-M231 at around 4.5%. Depending on the geographical location of samples, West Eurasian
mtDNA haplogroup lineages make up 27% to 42.6% in the Kyrgyz, range 14.6% Talas to 25.5% Sary-Tash
Autosomal DNA A 2011 study of autosomal ancestry found that East Eurasian ancestry is predominant in most Kyrgyz living in Kyrgyzstan. East Eurasian ancestry makes up roughly two-thirds with exceptions of Kyrgyz living in Tajikistan and the western areas of Kyrgyzstan, where it forms only half. A 2022 study found that Kyrgyz people derive most of their ancestry from Northern East Asian sources. Kyrgyz from China were found to have more West Eurasian-like ancestry than the Kyrgyz from Kyrgyzstan. The Kyrgyz are inferred to derive most of their ancestry from "Neolithic, Bronze, and Iron Age populations from northern China and Mongolia" (59.3–69.8%), suggesting "genetic continuity" with them. Their West Eurasian-like ancestry (24.9–37.5%) is represented by a combination of Bronze Age
Western Steppe Herders and "Iranian Farmer-related" ancestries (
BMAC). They also harbor minor ancestry associated with the earliest
Tarim mummies (3.2–5.3%). A 2023 study analyzed the genome of 70 Kyrgyz individuals from
Southern Xinjiang (SXJK). The authors found that the SXJK samples display genetic heterogenity and form two clusters along a 'Turkic cline', which stretched from
East Asians at the one end to "
Indo-Europeans" at the other end. The main cluster had 63.3–83.3%
Ancient Northeast Asian ancestry, with the remainder ancestry being derived from West Eurasian (Western Steppe Herders) and Tarim_EMBA-like sources, and displayed high genetic affinity to
Kazakhs and contemporary Kyrgyz from Kyrgyzstan. The secondary cluster had 47.2–55.6% Ancient Northeast Asian ancestry and higher West Eurasian ancestry, particularly via additional BMAC-related admixture (9.1–27.8%), and clustered closer to modern
Uyghurs. A 2025 study stated that there were more genetic similarities between Kyrgyz from Kyrgyzstan and Xinjiang than between northern and southern Han Chinese, with Kyrgyz from Xinjiang being modeled as a mixture of East Asian (41.7%), Siberian (25.6%), West Eurasian (25.2%) and South Asian (7.6%) ancestries. Kyrgyz from Xinjiang are also closely related to other Central Asians such as Uyghurs, Kazakhs and Hazaras but have less West Eurasian and South Asian ancestry than Uyghurs especially. == Religion ==
