The
First Turkic Khaganate was founded by
Bumin in 552 on the Mongolian Plateau and quickly spread west toward the
Caspian Sea. Within 35 years the Western Turkic Khaganate and the
Eastern Turkic Khaganate were independent polities. The Western Khaganate reached its peak under
Tong Yabghu Qaghan (618–630). After Tong's murder, there were conflicts between the Dulu and Nushibi factions and many short-lived Khagans, and some territory was lost. From 642 onward, the expanding
Tang dynasty began to interfere. The Tang destroyed the khaganate in 657–659.

Afrasiab murals, 7th century CE. The
Göktürks and
Mongols were the only two empires to rule both the eastern and central
steppe. The Göktürks were the first steppe empire to be in contact with the
Byzantine Empire,
Persia and China. Their expansion west from modern-day
Mongolia is poorly documented.
Lev Gumilyov gives the following.
Bumin gave the west to his younger brother
Istämi (553–575). The campaign probably began in the spring of 554 and apparently met little resistance. They took
Semirechye and by 555 had reached the
Aral Sea, probably on a line from the lower
Oxus, across the
Jaxartes, north of Tashkent to the western tip of the
Tian Shan. They drove before them various peoples:
Xionites,
Uar,
Oghurs and others. These seem to have merged into the
Avars whom the Göktürks drove across the
Volga River in 558, and who crossed the western steppe and reached Hungary by 567. The Turks then turned southeast. At this time the
Hephthalites held the
Tarim Basin,
Fergana,
Sogdia,
Bactria and
Merv, with the Persians at approximately their present border.
Khosrow I made peace with the Byzantines and turned on the Hephthalites. Fighting started in 560. The Persians won a victory in 562, and the Turks took
Tashkent. In 565, the Hephthalites were defeated at
Qarshi and withdrew to Bactria, where fragments of their people remained until the
Arab conquest. The Turks demanded the tribute formerly paid to the Hephthalites and when this was refused, they crossed the Oxus, but thought better of it and withdrew. In 571 a border was drawn along the Oxus, the Persians expanding east to Afghanistan, and the Turks gaining the Sogdian merchant cities and their control of the
Silk Road. Around 567–576, the Turks took the area between the Caspian and Black Seas. In 568 they took part of Bactria.
Late period (575–630) ''twrk x'γ'n''),
Tashkent, Western Turk period, 580-610. Istämi was followed by his son
Tardu (575–603). Around 581 he intervened in the eastern
Göktürk civil war. In 588–589 the Turks were defeated by Persians near
Herat in the first
Perso-Turkic War. In 599–603 he gained the eastern half of the Khaganate, but after his death the two halves were split again.
Heshana Qaghan (603–611) was driven out of Dzungaria and then defeated by
Shikui Khagan (610–617), Tardu's grandson. Shikui Khagan conquered the Altai, reconquered Tashkent and vanquished the
Sasanids and the
Hephthalites , raiding Iran as far as
Ray and
Isfahan.
Tokhara Yabghus and Turk Shahis ruler named Sri Ranasrikari "The Lord who brings excellence through war" (
Brahmi script). In this realistic portrait, he wears the Turkic double-lapel
caftan. Late 7th to early 8th century. Shikui Khagan's brother
Tong Yabghu Qaghan (618–630) ruled from the Tarim basin to the Caspian Sea, and met
Xuanzang. He sent men to fight the Persians south of the Caucasus, and also sent his son
Tardush Shad to fight in Afghanistan, where he established the
Tokhara Yabghus, who themselves projected the
Turk Shahis as far east as India. In the year of Tong's death the Tang dynasty defeated and annexed the Eastern Khaganate. He was murdered by his uncle
Külüg Sibir (630) with
Duolu support. The
Nushibi put Tong's son
Sy Yabgu (631–633) on the throne. However, Nushibi quickly rebelled against Sy and enthroned Ashina Nishu as
Duolu Qaghan (633–634), followed by his brother
Ishbara Tolis (634–638). There was a Dulu-Nushibi conflict and
Yukuk Shad (638–642), son of the final eastern khagan, was brought in. The factions quarreled and the Nushibi and
Emperor Taizong of Tang enthroned
Irbis Seguy (642–651). The Tang dynasty demanded part of the Tarim Basin and then seized part of it until the war ended with Taizong's death. Irbis was overthrown by
Ashina Helu (651–658) who, after about six years of war, was defeated at
Battle of Irtysh River and captured by the Tang. After this there were several puppet khagans. From 679 to 719 the old
Göktürk capital of
Suyab was one of the
Four Garrisons of Anxi. The Tang dynasty exercised control over the area until the time of
An Lushan's rebellion in 756.
Tang campaigns against the Western Turks (640–657) The Tang carried out a series of military campaigns against the Western Turkic Khaganate in the 7th century CE. Early military conflicts were a result of the Tang interventions in the rivalry between the Western and
Eastern Turks to weaken both. Under
Emperor Taizong, campaigns were dispatched in the
Western Regions against
Gaochang in 640,
Karasahr in 644 and 648, and
Kucha in 648. The wars against the Western Turks continued under
Emperor Gaozong, and the khaganate was annexed after General
Su Dingfang's defeat of Khagan Ashina Helu in 657.
Tang protectorate (657–742) The Western Turks attempted to capture the
Tarim Basin in 670 and 677 but were repelled by the Tang. In 679, the Tang general
Pei Xingjian led an army as far as
Tokharistan, as he was also escorting the last Sasanian pretender to the throne,
Narsieh, back to Persia. Pei Xingjian fought successfully against an invasion of
Anxi led by Western Turkic khagan
Ashina Duzhi, and numerous minor Turkic chieftains in the region then pledged their loyalty to the
Tang dynasty. Meanwhile, general Pei Xingjian lost interest in reinstalling the Persian king and left Narsieh in the Anxi Protectorate alone, although Narsieh was able to maintain his many servants and a high quality of life, and continued to fight against the Muslim Arabs for twenty years. Upon returning to Tang, Pei was appointed the minister of rituals and Great general of the right flank guards. In 679, the Turkic chieftain Ashide Wenfu rebelled. Protectorate general Xiao Siye, a noble from Lanling Commandery, was defeated by Ashide. Pei then took over the command from Xiao and decisively won a battle against the Turks in an ambush. Ashide fled. Not long after the first defeat, Ashide Wenfu gathered his troops and united them with the troops of another chieftain
Ashina Funian. Pei saw the distrust and suspicions between the two chieftains and exploited this weakness by driving a wedge between them. Eventually, Ashina Funian murdered Ashide Wenfu out of fear of Tang's revenge against him. When Funian was brought to the Tang court, he was executed regardless of the fact that he had surrendered his troops. Pei had promised Ashina that he would not be put to death; however, the court did not respect Pei's promise. Due to this incident, Pei retired. Ashina's death, according to
New Book of Tang, was a scheme against Pei Xingjian by his clansman
Pei Yan who was jealous about his victories in the west. In 682, Pei was again put in charge of pacifying yet another Turkic rebellion against the Tang dynasty. However, he died of old age before the troops were sent out. The imperial court awarded him the posthumous name Xian (獻) which means "Dedication", as well as the supreme military honorary title Taiwei (太尉). The areas controlled by the Tang dynasty came under the dynasty's cultural influences and the Turkic influence of the
ethnically Turkic Tang soldiers stationed in the region. Indo-European prevalence in Central Asia declined as the expeditions accelerated Turkic migration into what is now
Xinjiang. By the end of the 657 campaigns, the Tang had reached its largest extent. The Turks, Tibetans,
Muslim Arabs and the Tang competed for control over Central Asia until the collapse of the Tang in the 10th century. The
Second Turkic Empire defeated the fragmented Western Turks in 712 and absorbed the tribes into the new empire. == Relations with the Persians and Byzantines ==
