Göktürks in the context of "An Lushan"

The Kyrgyz people (also spelled Kyrghyz, Kirgiz, and Kirghiz; /ˈkɪərɡɪz/ KEER-giz or /ˈkɜːrɡɪz/ KUR-giz; Kyrgyz: Кыргыздар; قیرغیزدار) are a Turkic ethnic group native to Central Asia. They primarily reside in Kyrgyzstan, Uzbekistan, and China. A Kyrgyz diaspora is also found in Russia, Tajikistan, and Kazakhstan. They speak the Kyrgyz language, which is the official language of Kyrgyzstan.

The earliest people known as "Kyrgyz" were the descendants of several Central Asian tribes, first emerging in western Mongolia around 201 BC. Modern Kyrgyz people are descended in part from the Yenisei Kyrgyz that lived in the Yenisey river valley in Siberia. The Kyrgyz people were constituents of the Tiele people, the Göktürks, and the Uyghur Khaganate before establishing the Yenisei Kyrgyz Khaganate in the 9th century, and later a Kyrgyz khanate in the 15th century.

The Pannonian Avars (/ˈævɑːrz/ AV-arz) were an alliance of several groups of Eurasian nomads of various origins. The peoples were also known as the Obri (modern Russian: обры, Obry) in the chronicles of the Rus, the Abaroi or Varchonitai (Greek: Βαρχονῖται, romanized: Varchonitai), or Pseudo-Avars in Byzantine sources, and the Apar (Old Turkic: 𐰯𐰺) to the Göktürks. They established the Avar Khaganate, which spanned the Pannonian Basin and considerable areas of Central and Eastern Europe from the late-6th to the early-9th centuries.

The name "Pannonian Avars" (after Pannonia in the upper Danube basin where they eventually settled) is used to distinguish them from the Avars of the Caucasus, a separate people with whom the Pannonian Avars may or may not have had links. Although the name Avar first appeared in the mid-5th century, the Pannonian Avars entered the historical scene in the mid-6th century, on the Pontic–Caspian steppe as a people who wished to escape the rule of the Göktürks. They are probably best known for their invasions and destruction in the Avar–Byzantine wars from 568 to 626 and for their influence on the Slavic migrations to the Balkans.

Khan (/xɑːn/, /kɑːn/, /kæn/) is a historic Turkic and Mongolic title originating among nomadic tribes in the Central and Eastern Eurasian Steppe to refer to a king. It first appears among the Rouran and then the Göktürks as a variant of khagan (sovereign, emperor) and implied a subordinate ruler. In the Seljük Empire, it was the highest noble title, ranking above malik (king) and emir (prince). In the Mongol Empire it signified the ruler of a horde (ulus), while the ruler of all the Mongols was the khagan or great khan. It is a title commonly used to signify the head of a Pashtun tribe or clan.

The title subsequently declined in importance. During the Safavid and Qajar dynasty it was the title of an army general high noble rank who was ruling a province, and in Mughal India it was a high noble rank restricted to courtiers. After the downfall of the Mughals it was used promiscuously and became a surname. Khan and its female forms occur in many personal names, generally without any nobiliary of political relevance, although it remains a common part of noble names as well.

The Turkic migrations were the spread of Turkic tribes and Turkic languages across Eurasia between the 4th and 11th centuries. In the 6th century, the Göktürks overthrew the Rouran Khaganate in what is now Mongolia and expanded in all directions, spreading Turkic culture throughout the Eurasian steppes. Although Göktürk empires came to an end in the 8th century, they were succeeded by numerous Turkic empires such as the Uyghur Khaganate, Kara-Khanid Khanate, Khazars, and the Cumans. Some Turks eventually settled down into sedentary societies such as the Qocho and Ganzhou Uyghurs. The Seljuq dynasty invaded Anatolia starting in the 11th century, resulting in permanent Turkic settlement and presence there. Modern nations with large Turkic populations include Kyrgyzstan, Turkmenistan, Turkey, Azerbaijan, Uzbekistan, and Kazakhstan, and Turkic populations also exist within other nations, such as Chuvashia, Bashkortostan, Tatarstan and the Sakha Republic of Siberia in Russia, Northern Cyprus, the Crimean Tatars, the Kazakhs in Mongolia, the Uyghurs in China, and the Azeris in Iran.

Proto-Turkic is the linguistic reconstruction of the common ancestor of the Turkic languages that was spoken by the Proto-Turks before their divergence into the various Turkic peoples. Proto-Turkic separated into Oghur (western) and Common Turkic (eastern) branches. Candidates for the Proto-Turkic homeland range from western Central Asia to Manchuria, with most scholars agreeing that their migrations started from the eastern part of the Central Asian steppe, while one author has postulated that Proto-Turkic originated 2,500 years ago in East Asia.

The oldest records of a Turkic language, the Old Turkic Orkhon inscriptions of the 7th century Göktürk khaganate, already show characteristics of Eastern Common Turkic. For a long time, the reconstruction of Proto-Turkic relied on comparisons of Old Turkic with early sources of the Western Common Turkic branches, such as Oghuz and Kypchak, as well as the Western Oghur proper (Bulgar, Chuvash, Khazar). Because early attestation of these non-easternmost languages is much sparser, reconstruction of Proto-Turkic still rests fundamentally on the easternmost Old Turkic of the Göktürks, however it now also includes a more comprehensive analysis of all written and spoken forms of the language.

Tengrism (also known as Tengriism, Tengerism, or Tengrianism) is a belief system originating in the Eurasian steppes, based on shamanism and animism. It generally involves the titular sky god Tengri. According to some scholars, adherents of Tengrism view the purpose of life as to be in harmony with the universe.

It was the prevailing religion of the Göktürk, Hun, Xianbei, Bulgar, Xiongnu, Yeniseian and Mongolic peoples, as well as the state religion of several medieval states such as the First Turkic Khaganate, the Western Turkic Khaganate, the Eastern Turkic Khaganate, Old Great Bulgaria, the First Bulgarian Empire, Volga Bulgaria, Khazaria, and the Mongol Empire. In the Irk Bitig, a ninth century manuscript on divination, Tengri is mentioned as Türük Tängrisi (God of Turks). According to many academics, Tengrism was, and to some extent still is, a predominantly polytheistic religion based on the shamanistic concept of animism, and was first influenced by monotheism during the imperial period, especially by the 12th–13th centuries. Abdulkadir Inan argues that Yakut and Altai shamanism are not entirely equal to the ancient Turkic religion.
