When Ashina Xian's father was executed by
Lai Junchen in 692, he was exiled to
Yazhou. However, he was recalled to court in 703. In 708, he was appointed
Xingxiwang Khagan () by
Emperor Zhongzong of Tang. However,
Saqal was appointed as his subordinate, who was going to be appointed
Shisixing Khagan () later. In 714, after the death of Saqal at the
Battle of Bolchu, Xian was made Qixi (碛西) Military Commissioner and sent to
Suyab to fill the power vacuum. Nevertheless, when
Suluk rose to prominence, the Tang appointed Ashina Xian as the
Shixing Qaghan in 716 and appointed Suluk as his deputy, to appease Suluk. Suluk's growing ambition over Xian's overlordship resulted in war and the defeat of Xian in June and July in 717. After his defeat, he left for
Chang'an and died sometime during the reign of
Emperor Xuanzong. His successor was his son
Ashina Zhen. == References ==
