Turkic peoples are a collection of diverse ethnic groups of West, Central, East, and North Asia as well as parts of Europe, who speak Turkic languages.. "Turkic peoples, any of various peoples whose members speak languages belonging to the Turkic subfamily...". "The Turkic peoples represent a diverse collection of ethnic groups defined by the Turkic languages."

According to historians and linguists, the Proto-Turkic language originated in Central-East Asia,: "Most linguists and historians agree that Proto-Turkic, the common ancestor of all ancient and contemporary Turkic languages, must have been spoken somewhere in Central-East Asia (e.g. Róna-Tas, Reference Róna-Tas1991, p. 35; Golden, Reference Golden1992, pp. 124–127; Menges, Reference Menges1995, pp. 16–19)." potentially in the Altai-Sayan region, Mongolia or Tuva.: "The ultimate Proto-Turkic homeland may have been located in a more compact area, most likely in Eastern Mongolia": "The best candidate for the Turkic Urheimat would then be northern and western Mongolia and Tuva, where all these haplogroups could have intermingled, rather than eastern and southern Mongolia..." Initially, Proto-Turkic speakers were potentially both hunter-gatherers and farmers; they later became nomadic pastoralists.:"To sum up, the palaeolinguistic reconstruction points to a mixed subsistence strategy and complex economy of the Proto-Turkic-speaking community. It is likely that the subsistence of the Early Proto-Turkic speakers was based on a combination of hunting–gathering and agriculture, with a later shift to nomadic pastoralism as an economy basis, partly owing to the interaction of the Late Proto-Turkic groups with the Iranian-speaking herders of the Eastern Steppe." Early and medieval Turkic groups exhibited a wide range of both East Asian and West Eurasian physical appearances and genetic origins, in part through long-term contact with neighboring peoples such as Iranic, Mongolic, Tocharian, Uralic and Yeniseian peoples. : "It should also be noted that even the early Turkic peoples, including the Tiele and the Türks, were made up of heterogeneous elements. Importantly, DNA studies demonstrate that the expansion process of the Turkic peoples involved the Turkicization of various non-Turkic-speaking groups. The "Turks" intermixed with and Turkicized various indigenous groups across Eurasia: Uralic hunter-gatherers in northern Eurasia; Mongolic nomads in Mongolia; Indo-European-speaking nomads and sedentary populations in Xinjiang, Transoxiana, Iran, Kazakhstan, and South Siberia; and Indo-European elements (the Byzantine subjects, among others) in Anatolia and the Balkans.11" : "Moreover, Turks do not all physically look alike. They never did. The Turks of Turkey are famous for their range of physical types. Given the Turks' ancient Inner Asian origins, it is easy to imagine that they once presented a uniform Mongoloid appearance. Such traits seem to be more characteristic in the eastern Turkic world; however, uniformity of type can never have prevailed there either. Archeological evidence indicates that Indo-Europeans, or certainly Europoid physical types, inhabited the oases of the Tarim basin, Dzungaria, and even parts of Mongolia in ancient times. In the Tarim basin, persistence of these former inhabitants' genes among the modern Uyghurs is both observable and scientifically demonstrable.32 Early Chinese sources describe the Kirghiz as blue-eyed and blond or red-haired. The genesis of Turkic ethnic groups from earliest times occurred in confederations of diverse peoples. As if to prove the point, the earliest surviving texts in Turkic languages are studded with terms from other languages." "Some DNA tests point to the Iranian connections of the Ashina and Ashide,133 highlighting further that the Turks as a whole 'were made up of heterogeneous and somatically dissimilar populations'.134 Geographically, the accounts cover the regions of Inner Mongolia, Gansu, Xinjiang, the Yenisei zone and the Altay, regions with Turkic, Indo-European (Iranian [Saka] and Tokharian), Yeniseic, Uralic and other populations. Wusun elements, like most steppe polities of an ethno-linguistic mix, may have also played a substratal role." : "Both Chinese histories and modern dna studies indicate that the early and medieval Turkic peoples were made up of heterogeneous populations"

Many vastly differing ethnic groups have throughout history become part of the Turkic peoples through language shift, acculturation, conquest, intermixing, adoption, and religious conversion. Nevertheless, Turkic peoples share, to varying degrees, non-linguistic characteristics like cultural traits, ancestry from a common gene pool, and historical experiences. Some of the most notable modern Turkic ethnic groups include the Altai people, Azerbaijanis, Chuvash people, Gagauz people, Kazakhs, Kyrgyz people, Turkmens, Turkish people, Tuvans, Uyghurs, Uzbeks, and Yakuts.

Etymology

The first known mention of the term Turk (Old Turkic: 𐱅𐰇𐰼𐰰 Türük or 𐱅𐰇𐰼𐰰:𐰜𐰇𐰛 Kök Türük, < Middle Chinese *tɦut-kyat < *dwət-kuɑt, Old Tibetan: drugu) Orkhon inscriptions Bain Tsokto inscriptions applied to only one Turkic group, namely, the Göktürks, who were also mentioned, as türüg ~ török, in the 6th-century Khüis Tolgoi inscription, most likely not later than 587 AD. A letter by Ishbara Qaghan to Emperor Wen of Sui in 585 described him as "the Great Turk Khan". The Bugut (584 CE) and Orkhon inscriptions (735 CE) use the terms Türküt, Türk and Türük.Moriyasu & Ochir 1999, p. 123

During the first century CE, Pomponius Mela refers to the Turcae in the forests north of the Sea of Azov, and Pliny the Elder lists the Tyrcae among the people of the same area.Pliny, Natural History – Harvard University Press, vol. II (Libri III-VII); reprinted 1961, p. 351Pomponius Mela's Description of the World, Pomponius Mela, University of Michigan Press, 1998, p. 67Ercümend Kuran, Türk Adı ve Türklük Kavramı, Türk Kültürü Dergisi, Yıl, XV, S. 174, Nisan 1977. s. 18–20. However, English archaeologist Ellis Minns contended that Tyrcae Τῦρκαι is "a false correction" for Iyrcae Ἱύρκαι, a people who dwelt beyond the Thyssagetae, according to Herodotus (Histories, iv. 22), and were likely Ugric ancestors of Magyars. There are references to certain groups in antiquity whose names might have been foreign transcriptions of Tür(ü)k, such as Togarma, Turukha/Turuška, Turukku and so on; but the information gap is so substantial that any connection of these ancient people to the modern Turks is not possible.Peter B. Golden, Introduction to the History of the Turkic People, p. 12: "... source (Herod.IV.22) and other authors of antiquity, Togarma of the Old Testament, Turukha/Turuska of Indic sources, Turukku of Assyrian..."German Archaeological Institute. Department Teheran, Archaeologische Mitteilungen aus Iran, Vol. 19, Dietrich Reimer, 1986, p. 90

The Chinese Book of Zhou (7th century) presents an etymology of the name Turk as derived from 'helmet', explaining that this name comes from the shape of a mountain where they worked in the Altai Mountains.Sinor, Cambridge History of Early Inner Asia, Page 295 Hungarian scholar András Róna-Tas (1991) pointed to a Khotanese-Saka word, tturakä 'lid', semantically stretchable to 'helmet', as a possible source for this folk etymology, yet Golden thinks this connection requires more data.

It is generally accepted that the name Türk is ultimately derived from the Old-Turkic migration-term(Bŭlgarska akademii︠a︡ na naukite. Otdelenie za ezikoznanie/ izkustvoznanie/ literatura, Linguistique balkanique, Vol. 27–28, 1984, p. 17 𐱅𐰇𐰼𐰰 Türük/Törük,"Türk" in Turkish Etymological Dictionary, Sevan Nişanyan. which means 'created, born'Faruk Suümer, Oghuzes (Turkmens): History, Tribal organization, Sagas, Turkish World Research Foundation, 1992, p. 16) or 'strong'.American Heritage Dictionary (2000). The American Heritage Dictionary of the English Language: Fourth Edition – "Turk"". bartleby.com. Retrieved 7 December 2006. Turkologist Peter B. Golden agrees that the term Turk has roots in Old Turkic,Golden, Peter B. "Some Thoughts on the Origins of the Turks and the Shaping of the Turkic Peoples". (2006) In: Contact and Exchange in the Ancient World. Ed. Victor H. Mair. University of Hawaiʻi Press. p. 143. yet is not convinced by attempts to link Dili, Dingling, Chile, Tele, and Tiele, which possibly transcribed *tegrek (probably meaning 'cart'), to Tujue, which transliterated to Türküt.Golden, Peter B. (1992), An Introduction to the History of the Turkic Peoples, p. 93-95

Scholars, including Toru Haneda, Onogawa Hidemi, and Geng Shimin believed that Di, Dili, Dingling, Chile and Tujue all came from the Turkic word Türk, which means 'powerful' and 'strength', and its plural form is Türküt.T. Allsen, P. B. Golden, R. K. Kovalev, and A. P. Martinez (2012), ARCHIVUM EURASIAEMEDII AEV, p. 85 Even though Gerhard Doerfer supports the proposal that türk means 'strong' in general, Gerard Clauson points out that "the word türk is never used in the generalized sense of 'strong'" and that türk was originally a noun and meant "'the culminating point of maturity' (of a fruit, human being, etc.), but more often used as an [adjective] meaning (of a fruit) 'just fully ripe'; (of a human being) 'in the prime of life, young, and vigorous'".Clauson, G. An Etymological Dictionary of Pre-13th Century Turkish (1972). p. 542-543 Hakan Aydemir (2022) also contends that Türk originally did not mean "strong, powerful" but "gathered; united, allied, confederated" and was derived from the Pre-Proto-Turkic verb *türü "heap up, collect, gather, assemble".

The earliest Turkic-speaking peoples identifiable in Chinese sources are the Yenisei Kyrgyz and Xinli, located in South Siberia.The Peoples of the Steppe Frontier in Early Chinese Sources, Edwin G. Pulleyblank, page 35 Another example of an early Turkic population would be the Dingling.Hyun Jin Kim: Huns, Rome and the Birth of Europe. Cambridge University Press, 2013. pp.175–176.Xu Elina-Qian, Historical Development of the Pre-Dynastic Khitan, University of Helsinki, 2005. p. 176.

In Late Antiquity itself, as well as in and the Middle Ages, the name "Scythians" was used in Greco-Roman and Byzantine literature for various groups of nomadic "barbarians" living on the Pontic-Caspian Steppe who were not related to the actual Scythians.: "Greek authors [...] frequently applied the name Scythians to later nomadic groups who had no relation whatever to the original Scythians" Medieval European chroniclers subsumed various Turkic peoples of the Eurasian steppe as "Scythians". Between 400 CE and the 16th century, Byzantine sources use the name Σκύθαι (Skuthai) in reference to twelve different Turkic peoples.G. Moravcsik, Byzantinoturcica II, p. 236–39

In the modern Turkish language as used in the Republic of Turkey, a distinction is made between "Turks" and the "Turkic peoples" in loosely speaking: the term Türk corresponds specifically to the "Turkish-speaking" people (in this context, "Turkish-speaking" is considered the same as "Turkic-speaking"), while the term Türki refers generally to the people of modern "Turkic Republics" (Türki Cumhuriyetler or Türk Cumhuriyetleri). However, the proper usage of the term is based on the linguistic classification in order to avoid any political sense. In short, the term Türki can be used for Türk or vice versa.Jean-Paul Roux, Historie des Turks – Deux mille ans du Pacifique á la Méditerranée. Librairie Arthème Fayard, 2000.
