Five tribes (called Duolu) to the northeast and five tribes to the southwest (called Nushibi) formed the two rival factions, the border line being Ili River.
But the Dulu faction enthroned Taman (also called Heshana Khan) who was a generation younger than Sheguy.
Nushibi clan as well as Silk Road merchants who suffered from the increasing anarchy supported Sheguy to throne in 611.
[4] Sheguy maintained order in his empire and provided security of the silk road.
In 618, he was succeeded by his brother Tong during whose reign Western Turkic Empire reached to apogee.
