Nushibi

The Nushibi tribes occupied the lands of the Western Turkic Khaganate west of the Ili River of contemporary Kazakhstan.

Yury Zuev reconstructs Nushibi's Middle Chinese pronunciation as nou siet-piet,[3] which, he asserts, transcribes Turkic oŋ šadapït "right[4] wing".

[5] Nurlan Kenzheakhmet etymologised 弩失畢 (MC: nuǝ-șit-pjit) as Chinese transcription of Sogdian nšypyk (*nišēbīg), nšmy (*nišame), meaning "west".

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.

The period of Nushibi dominance was interrupted in 628 by a joined revolt of Karluks and Duolu tribes, and a consequent death of Tong Yabghu 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 to 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.

Külüg Sibir was killed in 631, and Nushibi installed their choice, son of Tong Yabghu Qaghan with a title Irbis Ishbara Sir Yabghu (not to be confused with Irbis Ishbara Yabgu Qaghan), whose title Sir received the graphically pejorative Chinese transliteration 肆 Sì (< MC */siɪH/) "impudent, undisciplined".

Duolu occupied northern portion of the Middle Asia steppes, away from the main artery of the Silk Road, and were little affected by the intracontinental trade.

Nushibi occupied lands south of Duolu, controlled a major stretch of the caravan road artery and numerous branches, and were profoundly affected by its operation.

Bilingual Turkic-Sogdian merchants[24] operated the constellation of oasis city-states with a common name Sogdiana and established a symbiotic relationship with their Nushibi nomadic sponsors.
