The First Turkic Khaganate, also referred to as the First Turkic Empire, the Turkic Khaganate or the Göktürk Khaganate, was a Turkic khaganate established by the Ashina clan of the Göktürks in medieval Inner Asia under the leadership of Bumin Qaghan (d. 552) and his brother Istämi. The First Turkic Khaganate succeeded the Rouran Khaganate as the hegemonic power of the Mongolian Plateau and rapidly expanded their territories in Central Asia. The khaganate became the first Central Asian transcontinental empire from Manchuria to the Black Sea.
Although the Göktürks spoke a Siberian Turkic language, the direct predecessor to the Orkhon Turkic of the Second Turkic Khaganate, the First Khaganate's early official texts and coins were written in Sogdian. It was the first Turkic state to use the name Türk politically. The Old Turkic script was invented in the first half of the sixth century.
The Khaganate collapsed in 603, after a series of conflicts and civil wars which separated the polity into the Eastern Turkic Khaganate and Western Turkic Khaganate. Tang China conquered the Eastern Turkic Khaganate in 630 and the Western Turkic Khaganate in 657 in a series of military campaigns. The Second Turkic Khaganate emerged in 682 and lasted until 744, when it was overthrown by the Uyghur Khaganate.
History
Origin The origins of the Turkic Khaganate trace back to 546, when Bumin Qaghan made a preemptive strike against the Uyghur and Tiele groups planning a revolt against their overlords, the Rouran Khaganate. For this service, he expected to be rewarded with a Rouran princess, thus marrying into the royal family. However, the Rouran khagan, Yujiulü Anagui, sent an emissary to Bumin to rebuke him, saying, "You are my blacksmith slave. How dare you utter these words?" As Anagui's "blacksmith slave" () comment was recorded in Chinese chronicles, some claim that the Göktürks were indeed blacksmith servants for the Rouran elite,馬長壽, 《突厥人和突厥汗國》, 上海人民出版社, 1957, p. 10–11 陳豐祥, 余英時, 《中國通史》, 五南圖書出版股份有限公司, 2002, , p. 155 Gao Yang, "The Origin of the Turks and the Turkish Khanate", X. Türk Tarih Kongresi: Ankara 22 – 26 Eylül 1986, Kongreye Sunulan Bildiriler, V. Cilt, Türk Tarih Kurumu, 1991, s. 731. and that "blacksmith slavery" may have indicated a form of vassalage within Rouran society. According to Denis Sinor, this reference indicates that the Turks specialized in metallurgy, although it is unclear if they were miners or blacksmiths.Denis Sinor, Inner Asia: history-civilization-languages: a syllabus, Routledge, 1997, , p. 26. Contacts had already begun in 545 A.D. between the so-called "blacksmith-slave" Türk and certain of the kingdoms of north China,Denis Sinor, ibid, p. 101. 'Beyond A-na-kui's disdainful reference to his "blacksmith slaves" there is ample evidence to show that the Turks were indeed specializing in metallurgy, though it is difficult to establish whether they were miners or rather blacksmiths.' Whatever the case, it was clearly indicated that the Turks were "slaves" that were not be taken literally, but rather a form of vassalage, or an unequal alliance.
A disappointed Bumin allied with the Western Wei against the Rouran, their common enemy, by marrying Princess Changle. In 552, Bumin defeated Anagui and his forces north of Huaihuang (modern Zhangjiakou, Hebei).Linghu Defen et al., Book of Zhou, Vol. 50.
This effectively ended the Rouran, which had for the previous century and a half been the dominant power on the eastern steppe.
Western expansion Having excelled both in battle and diplomacy, Bumin declared himself Illig Khagan of the new Khaganate at Ötüken, but died only months later. He was succeeded by his son Qara who also died shortly. The newly established empire was then divided among Bumin's other son, Muqan Qaghan and his brother Istämi.
Muqan ruled over the eastern part of the empire centered on Mongolia and defeated the Hephthalite Empire.Li Yanshou (李延寿), History of Northern Dynasties, Vol. 99. Bumin's brother Istämi (d. 576) bore the title "Yabghu of the West". This western branch of the Ashina clan was de facto independent while the eastern khagan was formally recognized as the senior. In 557, Istämi forged an alliance with Khosrow I of the Sassanid Empire of Iran to defeat and destroy the Hephthalites, who were allies of the Rouran. This resulted in the establishment of a common border between the two empires. This war tightened the Ashina clan's grip on the Silk Road. The alliance with Northern China was further reinforced in 568 through the marriage of the Turkic princess Ashina, daughter of Muqan Qaghan, with Emperor Wu of the Xianbei-led Chinese Northern Zhou dynasty.
The appearance of the Pannonian Avars in the West has been interpreted as a nomadic faction fleeing the westward expansion of the Göktürks, although the specifics are a matter of debate given the lack of clear sources and chronology. Rene Grousset links the Avars with the downfall of the Hephthalites rather than the Rouran, while Denis Sinor argues that Rouran-Avar identification is "repeated from article to article, from book to book with no shred of evidence to support it".History and historiography of the Nomad Empires of Central Eurasia. D Sinor. Acta Orientalia Academiae Scientarum Hung. 58 (1) 3 – 14, 2005
Istämi's policy of western expansion brought the Göktürks into Europe.Walter Pohl, Die Awaren: ein Steppenvolk im Mitteleuropa, 567–822 n. Chr, C.H.Beck (2002), , p. 26–29. In 576 the Göktürks crossed the Kerch Strait into the Crimea. Five years later they laid siege to Chersonesus; their cavalry kept roaming the steppes of Crimea until 590.Grousset 81. As for the southern borders, they were drawn south of the Amu Darya, bringing the Ashina into conflict with their former allies, the Sasanian Empire. In 589, the Sasanian Empire attacked and defeated the Türks. Much of Bactria (including Balkh) remained a dependency of the Ashina until the end of the century.
Relations with the Byzantine Empire
The Göktürks played a major role in the Byzantine Empire's relationship with the Persian Sasanian Empire. First contact with the Byzantines is believed to have happened in 563 and relates to an incident in 558 where the slaves of the Turks (the Pannonian Avars) ran away during their war with the Hephthalites.
The second contact occurred when Maniah, a Sogdian diplomat, convinced Istämi (also known as Silziboulos in Greek writingsEliot, C. (1908). Turkey in Europe. United Kingdom: E. Arnold. Page 76) of the Göktürks to send an embassy directly to the Byzantine Empire's capital Constantinople, which arrived in 568 and offered silk as a gift to emperor Justin II and where they discussed an alliance. Justin II seems to have been more interested in securing an ally to the rear of the Sasanians with whom they had been in almost permanent conflict rather than the importation of silk. In 569 an embassy led by Zemarchus occurred which was well received and likely solidified their alliance for war.
Another set of embassies occurred in 575–576 led by Valentine which were received with hostility by Turxanthos due to alleged treachery. They required the members of the Byzantine delegation at the funeral of Istämi to lacerate their faces to humiliate them. The subsequent hostility shown by the new ruler Tardu would be matched in Byzantine writings.Maurice, Strategikon, ed. Dennis and Gamillscheg, 360; With the insults reflecting a breakdown of the alliance, the likely cause is that the anger was due to the Turks not having their expectations met from their agreements and realising they were being used when they no longer aligned with the current goals of the Byzantine Empire (who correspondingly did not trust the Turks as partners).
Civil war
When the fourth ruler of the khaganate, Taspar Qaghan, died in 581, the realm split in two over his succession. He had willed the title of khagan to Muqan's son Apa Qaghan, but the high council appointed Ishbara Qaghan instead. Factions formed around both leaders. Before long, four rivals claimed the title. They were successfully played off against each other by the Sui and Tang dynasties.
Istämi's son, Tardu the leader of the western Turks, made a bid for total independence. He seized the title and led an army east to claim the seat of imperial power, Ötüken.
In order to support his position, Ishbara of the Eastern Khaganate, acknowledged the suzerainty of Emperor Yang of Sui in order to seek their protection. Tardu attacked Chang'an, the Sui capital, around 600, demanding Emperor Yangdi end his interference in the civil war. In retaliation, Sui diplomacy successfully incited a revolt of Tardu's Tiele vassals, which led to the end of Tardu's reign in 603. Among the dissident tribes were the Uyghurs and Xueyantuo.
Eastern Turkic Khaganate
The civil war left the empire divided into eastern and western parts. The eastern part, still ruled from Ötüken, remained in the orbit of the Sui and retained the name Göktürk. Shibi Khan (609–619) and Illig Qaghan (620–630) attacked the Central Plain at its weakest moment during the transition between the Sui and Tang. Shibi Khan's surprise attack against Yanmen Commandery during an imperial tour of the northern frontier almost captured Emperor Yang, but his ethnic Han wife Princess Yicheng—who had been well treated by Empress Xiao during an earlier visit—sent a warning ahead, allowing the emperor and empress time to flee to the commandery seat at present-day Daixian in Shanxi. This was besieged by the Turkic army on September 11, 615,Sima Guang, Zizhi Tongjian, Vol. 182. but Sui reinforcements and a false report from Princess Yicheng to her husband about a northern attack on the khaganate caused him to lift the siege before its completion.
In 626, Illig Qaghan took advantage of the Xuanwu Gate Incident and drove on to Chang'an. On September 23, 626,武德九年 八月癸未 Academia Sinica Illig Qaghan and his iron cavalry reached the bank of the Wei River north of Bian Bridge (in present-day Xianyang, Shaanxi). On September 25, 626, Emperor Taizong of Tang met Illig Qaghan on the border bridge, Taizong accused Illig Qaghan of crossing the border, Illig saw that Taizong was imposing and mistakenly thought that the reinforcements from the Tang dynasty had arrived, and was asked to duel. Illig was afraid and agreed to retreat in an alliance, which is called the Weishui Alliance (渭水之盟) or the Alliance of Bian Qiao (便橋會盟 / 便桥会盟). On the third day after the meeting, the Illig Qaghan sent 3,000 horses and 10,000 sheep to the border as compensation to the Tang dynasty, which Emperor Taizong did not accept, believing that this was too little. All in all, 67 incursions into China proper were recorded.
Before mid-October 627, heavy snows on the Mongolian–Manchurian grassland covered the ground to a depth of several feet, preventing the nomads' livestock from grazing and causing a massive die-off among the animals.David Andrew Graff, Medieval Chinese warfare, 300–900, Routledge, 2002, , p. 186. According to the New Book of Tang, in 628, Taizong mentioned that "There has been a frost in midsummer. The sun had risen from same place for five days. The moon had had the same light level for three days. The field was filled with red atmosphere (dust storm)."Ouyang Xiu, New Book of Tang, Vol. 215-I
Illig Qaghan was brought down by a revolt of his Tiele vassal tribes (626–630), allied with Emperor Taizong of Tang. This tribal alliance figures in Chinese records as the Huihe (Uyghur).
