 After being converted to Islam, the descendants of the previously Buddhist Uyghurs in Turfan failed to retain memory of their ancestral legacy and falsely believed that the "infidel Kalmuks" (Dzungars) were the ones who built Buddhist monuments in their area.The Dzungars lost control of Dzungari and the Tarim Basin to the Manchu Qing dynasty as a result of the Dzungar–Qing Wars (1687–1757).Between 1755 and 1760 the Qing Qianlong Emperor finally conquered the Dzungarian plateau and the Tarim Basin, bringing the two separate regions, respectively north and south of the Tianshan mountains, under his rule as Xinjiang.
