Duolu

The Old Turkic name behind those has been reconstructed, variously and with uncertainty, as *Tör-ok,[1] *Turuk,[2] *Tuğluq,[3] Tölük,[4] Türük,[5] and most recently Tuğluğ (𐱃𐰆𐰍𐰞𐰍) "have flags, have standards".

Initially, Western Turks might have organized themselves into eight tribes, consistent with statements by Syriac and Greek authors: John of Ephesus mentioned eight rulers of the Turks besides Istämi; and Menander Protector mentioned that at Istämi's death, the Western Turkic realm was divided into eight parts.

Later on, two Nushibi tribes, Axijie and Geshu, reformed themselves, each sub-divided into two sub-tribes, bringing the total number to ten.

Therefore, Western Turks were also called the Onoq or 'ten arrows', that is 'ten tribes', five led the Duolu chors (chuo 啜)[b] and five by the Nushibi erkins (sijin 俟斤).

Chinese sources (Old Book of Tang, Tongdian) record of Duolu tribal names & titles:

The lands of the Duolu were in the Ili River Basin
