The Turkic peoples are a collection of ethnic groups that live in northern, central and western Asia, northwestern China and parts of eastern Europe. They speak languages belonging to the Turkic language family. They share, to varying degrees, certain cultural traits and historical backgrounds. The term Turkic represents a broad ethno-linguistic group of people including existing societies such as the Turkish, Azerbaijani, Chuvashes, Kazakhs, Tatars, Kyrgyzs, Turkmens, Uyghurs, Uzbeks, Bashkirs, Qashqai, Gagauzs, Yakuts, Crimean Karaites, Krymchaks, Karakalpaks, Karachays, Nogais and as well as past civilizations such as the Göktürks, Kumans, Kipchaks, Avars, Bulgars, Turgeshes, Khazars, Seljuk Turks, Ottoman Turks, Mamluks, Timurids and possibly Huns and the Xiongnu.

The distribution of people of Turkic cultural background ranges from Siberia, across Central Asia, to Eastern Europe. As of 2011^[update] the largest groups of Turkic people live throughout Central Asia—Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan, and Azerbaijan, in addition to Turkey and Iran. Additionally, Turkic people are found within Crimea, East Turkistan region of western China, northern Iraq, Pakistan, Israel, Russia, Afghanistan, and the Balkans: Moldova, Bulgaria, Romania, and former Yugoslavia. A small number of Turkic people also live in Vilnius, the capital of Lithuania. Small numbers inhabit eastern Poland and the south-eastern part of Finland. There are also considerable populations of Turkic people (originating mostly from Turkey) in Germany, United States, and Australia, largely because of migrations during the 20th century.

The Kyrgyz (also spelled Kirgiz, Kirghiz) are a Turkic people living primarily in Kyrgyzstan.

There are several etymological theories on the ethnonym "Kyrgyz."

The word "Kyrgyz" is derived from the Turkic word "forty", with -Iz being an old plural suffix, referring to a collection of forty tribes.

Turkish people, also known as the "Turks" (Turkish: singular: Türk, plural: Türkler), are a nation and ethnic group primarily living in Turkey, and in the former lands of the Ottoman Empire where Turkish minorities have been established in the Balkans, the island of Cyprus, the Levant, Meskhetia, and North Africa. The Turkish minorities are the second largest ethnic groups in Bulgaria and Cyprus. In addition, due to modern migration, a Turkish diaspora has been established, particularly in Western Europe (see Turks in Europe), where large communities have been formed in Austria, Belgium, France, Germany, the Netherlands and the United Kingdom. There are also Turkish communities living in Australia, the former Soviet Union and the United States.

Although Turkic languages may have been spoken as early as 600 BC, the name "Turk" first appeared in Chinese sources and derives from the term "Tujue" (T’u-chue), meaning "strong" or "powerful", which was used in the 6th century C.E. to refer to the Göktürks.

The Chuvash people (Chuvash: Чăвашсем; Russian: Чуваши) are a Turkic ethnic group, native to an area stretching from the Volga Region to Siberia. Most of them live in Republic of Chuvashia and surrounding areas, although Chuvash communities may be found throughout all Russia.

There is no universally accepted etymology of the word Chuvash. However, there are two main theories that try to explain it.

According to one theory, "Chuvash" is a Shaz-Turkic adaptation of Lir-Turkic Suvar, an ethnonym of people that are widely considered to be the ancestors of modern Chuvashes. Compare Lir-Turkic Chuvash: huran to Shaz-Turkic Tatar: qazan (cauldron).

Another theory suggests that the word "Chuvash" may be derived from Common Turkic jăvaš ("friendly", "peaceful") as opposed to şarmăs ("warlike").

There are rival schools of thought on the origin of Chuvash people. One is that they originated from a mixing between the Turkic Suar and Sabir tribes of Volga Bulgaria with local Mari tribes and also the Finno-Ugrian population of the Volga Basin. Another is that the Chuvash are a remainder of the pre-Volga Bulgar population of the Volga region, merged with Scythians, Volga Bulgars and Mari.

The Turkomen also known as Oghuz Turks (a linguistic term designating the Western Turkic or Oghuz languages from the Oghur languages) were a historical Turkic tribal confederation in Central Asia during the early medieval Turkic expansion. The name Oghuz is just the Common Turkic  word for "tribe". They are referred to as "Western Turks" because they moved west from other Turkic peoples after the Göktürk empire collapsed, and because the majority of the areas in which they inhabit today (except Turkmenistan and the Turkmen Sahra) are west of the Caspian Sea, while those referred to as "Eastern Turks" live east of the Caspian Sea. The founders of the Ottoman Empire were also Oghuz Turks.

In the 9th century, the Oghuz Turks from the Aral steppes drove the Pecheneg Turks, of the Emba region and the Ural River, toward the west. In the 10th century they inhabited the steppe of the rivers Sari-su, Turgai, and Emba to the north of Lake Balkhash of modern day Kazakhstan. A clan of this nation, the Seljuks, embraced Islam and in the 11th century entered Persia, where they founded the Great Seljuk Empire. Similarly, in the 11th century a Tengriist Oghuz clan—referred to as Uzes or Torks in the Russian chronicles—overthrew Pecheneg supremacy in the Russian steppe. Harried by another Turkic horde, the Kipchaks—a branch of the Kimaks of the middle Irtysh or of the Ob—these Oghuz penetrated as far as the lower Danube, crossed it and invaded the Balkans, where they were either crushed or struck down by an outbreak of plague, causing the survivors either to flee or to join the Byzantine imperial forces as mercenaries (1065).
