Ashina Xichun, also known as Ilteber Shad () or Chuluo Khagan (Turkic: ÃÂula Han, , Middle Chinese: (Guangyun) , died ), was the khagan of the Eastern Turkic Khaganate, and second son of Yami Qaghan. He succeeded his elder brother Shibi and ruled for 18 months.
Ashina Xichun succeeded his brother Shibi Qaghan as khagan of the Eastern Turkic Khaganate in 619, as Shibi's son Ashina Shibobi was still a minor. He made Shibobi Nipu shad and appointed eastern territories to him. He terminated the campaign started by his brother after receiving a large tribute from the Tang.
Nevertheless, he created Yang Zhengdao, a posthumous son of Yang Jian, as a puppet king of Sui (éÂÂÃ¥ÂÂçÂÂ). Starting to plan a major assault as advised by Liang Shidu, he became allied to Wang Shichong and Dou Jiande. As part of the plan, he requested Dou to cross the Taihang Mountains and meet him at Jin (æÂÂå·Â, roughly modern Linfen, Shanxi) and Jiang (çµ³å·Â, roughly modern Yuncheng, Shanxi) Prefectures.
However he died from illness, possibly poisoned by the Minister of Ceremonies () Zheng Yuanshu (éÂÂå Âç¹). The perpetrators were executed by Illig Qaghan.
He married the Sui dynasty's Princess Yicheng (義æÂÂ堬主) in heqin, the former wife of Yami Qaghan in a levirate marriage along with other wives. Issue:
