Kül-chor

Kül-chor, (Old Turkic: Küli Čur), known in Arabic sources as Kūrṣūl (كورصول) and identified with the Baga Tarkhan (Chinese: 莫贺达干; pinyin: Mòhè Dágān) of the Chinese records, was one of the main Turgesh leaders under the khagan Suluk. He is chiefly known for his role in the Turgesh wars against the Umayyad Caliphate in Transoxiana, and for being responsible for the murder of Suluk in 738, precipitating the collapse of Turgesh power. After eliminating his rivals, he rose to become khagan himself, but soon fell out with his Chinese backers and was defeated and executed in 744. Some Arabic sources, however, record that he was killed by the Arabs in 739.
