Ashina clan
After Bilge Qaghan died, a factional struggle arose within the ruling Ashina clan. An alliance of Basmyls, Uyghurs and Karluks overthrew Göktürks and in the spring of 745 killed the last Ozmish Qaghan. At first, the Basmyl chief was elected a Kaghan titled Eletmish Kaghan (742—744), but he was soon overthrown by the allies, who elected Kutlug Boyla as Kutlug Bilge Kaghan.
