Zhenu rebelled and sought military support from the Qapagan Khaghan of the Second Turkic Khaganate in 708. Qapaghan Khagan defeated the Turgesh in 711 in the Battle of Bolchu, and killed both Saqal and Zhenu. The defeated Turgesh fled to Zhetysu. In 714 the Turgesh elected Suluk as their khagan. Timeline of Suluk In 720 Turgesh forces led by Kül-chor defeated Umayyad forces led by Sa'id ibn Abdu'l-Aziz near Samarkand. In 722 Suluk married the Tang Princess Jiaohe. In 724 Caliph Hisham sent a new governor to Khorasan, Muslim ibn Sa'id, with orders to crush the "Turks" once and for all, but, confronted by Suluk on the so-called "Day of Thirst", Muslim hardly managed to reach Samarkand with a handful of survivors, as the Turgesh raided freely. In 726 the Turgesh attacked Qiuci (Kucha). In 727 the Turgesh and the Tibetan Empire attacked Qiuci (Kucha). In 728 Suluk defeated Umayyad forces while aiding the Sogdians in their rebellion, and took Bukhara. In 731 the Turgesh were defeated at the Battle of the Defile by the Arabs, who suffered enormous casualties. In 735 the Turgesh attacked Ting Prefecture (Jimsar County). In the winter of 737 Suluk, along with his allies al-Harith, Gurak (a Sogdian leader) and men from Usrushana, Tashkent and the Khuttal attacked the Umayyads. He entered Jowzjan, but was defeated by the Umayyad governor Asad at the Battle of Kharistan. Kül-chor Following his defeat Suluk was murdered by his relative Kül-chor. Immediately, the Turgesh Khagante was plunged into a civil war between the Black (Kara) and Yellow (Sary) factions. Kül-chor of the Sary Turgesh vanquished his rival Tumoche of the Kara Turgesh. In 740 Kül-chor submitted to the Tang dynasty but rebelled anyway when he killed the Turgesh puppet sent by the Tang court in 742. He was then captured and executed by the Tang in 744. The last Turgesh ruler declared himself a vassal of the recently established Uyghur Khaganate. In 766 the Karluks conquered Zhetysu and ended the Turgesh Khaganate. Legacy Tuhsi and Azi might be remnants of the Türgesh, according to Gardizi, as well as Khalaj.<ref>Gumilyov, L.
