Dzungar conquest of Altishahr
The Dzungar conquest of Altishahr resulted in the Oirat led Dzungar Khanate in Dzungaria conquering and subjugating the Genghisid-ruled Yarkent Khanate in Altishahr. It put a final end to the independence of the Yarkent Khanate.
Prelude
Altishahr, referring to the southern Tarim Basin, was the core territory of the Chagatai Yarkent Khanate. By the mid-17th century, the Khanate, resisted the rising Oirat power Uunder Abdull ̄ah Khan, beating back Oirat inroads into the Khotan region and Aksu. The pressure from the Oirats began to increase in Abdull ̄ah Khan’s later years, under the Dzungar khong taiji, Sengge. A bitter battle between Sengge and Abdull ̄ahKhan ended in a truce; but the Dzungars now began to encouragec Abdull ̄ah’s son Yolb ̄arsto rebel against him.Conquest
The Naqshbandi Sufi Khojas, descendants of the Prophet Muhammad, had replaced the Chagatayid Khans as the ruling authority of the Tarim Basin in the early 17th century. There was a struggle between two factions of Khojas, the Afaqi faction and the Ishaqi faction.In 1678, Ismail Khan drives out to the Aq Taghliq Khoja of Afaq Khoja, seeking assistance from the 5th Dalai Lama, who in turn writes a letter to the Dzungar Khanate's leader Galdan Boshugtu to intervene on his behalf.After reaching his letter, Galdan had moved to the cities of Hami and Turpan, capturing or sieging the cities by 1679. Later the following year Galdan led 120,000 Dzungar cavalry into the Tarim basin, advancing through Aksu and Uch- Turfan, Kashghar, Yarkand and Khotan killing Ismail's family and establishing Abd ar-Rashid Khan II as the regional ruler.The 5th Dalai Lama received war spoils from the Dzungar Khan Galdan which were seized from the Muslims. The Muslims were called "heretics" by them.
