Ilterish Qaghan

Ilterish Qaghan (Old Turkic: , Elteris qaγan, 頡跌利施可汗/颉跌利施可汗, personal name: Ashina Qutlugh, 阿史那骨篤祿/阿史那骨笃禄, āshǐnà gǔdǔlù, a-shih-na ku-tu-lu) (died 694), was the founder of the Second Turkic Khaganate (reigning 682–694). In the 680s he left the sinicized tribes near China and returned to the Mongolian steppe, from where he raised an army and reconquered most of the lands of the first Eastern Turkic Khaganate. His name Il-teris means uniter, refounder (teriş) of the nation (il). He was succeeded by his brother, Qapaghan Qaghan, because his son Bilge Qaghan was too young.
