Nushibi

After the split of the First Turkic Khaganate in 604, the Western Turkic Kaganate was initially three-tribe Nushibi right wing and five-tribe Duolu left wing.[9] Later on, two Nushibi tribes, Äskäl and Qoshu, reorganized themselves, each subdivided into two tribes, bringing the total numbers to ten, thus the collective name On Oq (Ch. 十箭 "ten arrows"). Both Nushibi and Duolu belonged to the Turkic tribes of the Chuy group, and spoke close dialects.[10]

The transfer of supremacy from the Duolu group to Nushibi had outcome reverberating across Erasian continent. Nushibi controlled, and benefited, from the operation of their section of the transcontinental trade road (Silk Road), and were in alliance with Sogdiana, a chain of small oasis principalities who were also members of the Western Turkic Khaganate, and served as main operators of the Silk Road. Nushibi interest in the Silk Road operation brought them, in addition to the Sogdians, into a coalition with Byzantine and China, two other superpowers interested in the east-west trade. In the west, the coalition included Khazars in the N. Caucasus, and Bulgars in the N. Pontic steppes. This alignment was opposed a coalition of two other powers, Persia and the Eastern Turkic Kaganate, which brought about the first world wars of the 7th century Early Middle Ages.[11][12]

Nushibi interests in the Western Turkic Kaganate were advanced by the Kagan Tong Djabgu Qaghan, known from the Armenian annals as "King of the North". The capital was located north of Chach (modern Tashkent) oasis. The period of Nushibi dominance was interrupted in 628 by a joined revolt of Karluks and Doulu tribes, and a consequent death of Tong Jabgu Qaghan from the hands of his uncle. In the interregnum, led by his uncle Külüg Sibir with a title Baghatur Qaghan, the Duolu fraction restored its former dominating position. The coup brought a considerable upshot, in 630 Baghatur-Qaghan had to grant Bulgars their independence and allow them reorganize as what became known as Great Bulgaria.[13] Nushibi opposition to the usurper was headed by Ashina Nishu, a ruler with a seat in Paykend (Paikent), who ruled Bukhara province. Sibir-Khan was killed in 631, and Nushibi installed their choice, son of Tong-djabgu-kagan with a title Irbis Ishbara Jabgu-Qaghan, who received a derisive nickname Sy Jabgu (Middle Chinese 肆 */siɪ^H/ "impudent, undisciplined"), and was known to western contemporaries as Sinjibu and Silzibul [14] but soon had to replace him with Ashina Nishu under a name Duolu Qaghan (632–634), probably to appease the northern Duolu tribes. The next succession followed the traditional lateral succession order, a younger brother of Nishu was enthroned with a title Yshbara Tolis-shad (634–639), he enacted a major reform by consenting to the Doulu and Nushibi wings' autonomy and native leadership, not drawn from the Ashina clan. The order, favorable to the Duolu and Nushibi, was hurtful to the Karluks, Yagma, Kipchaks, Basmals, and worst of all to the descendants of the Eastern / Northern Xiongnu – Chuyüe (later Shatuo) and Chumi they were especially anguished because their Chumuhun kins were in the privileged Duolu and Chuban in both Duolo & Nushibi wings.[13]

In 647 the Western Turkic Kaganate was split into two independent states as a result of Ili River treaty. The independence period lasted until the rise of the Second Turkic Khaganate. In 667 the Nushibi wing of the On oq allied with Tibet.[15] At about 720, a campaign led by Kul Tegin defeated the forces of the Nushibi tribal union led by the Ezgil (Izgil) tribe, and subjugated the former "western wing", which from that time disappeared from the literature. The episode of the military campaign is mentioned in the Bilge Kagan inscription in the Orkhon inscriptions.[16]
