The Buddhist Uyghurs of the Kingdom of Qocho and Turfan embraced Islam after conversion at the hands of the Muslim Chagatai Khizr Khwaja.

Kara Del was a Mongolian ruled and Uighur populated Buddhist Kingdom.
The Muslim Chagatai Khan Mansur invaded and used the sword to make the population convert to Islam.

After being converted to Islam, the descendants of the previously Buddhist Uyghurs in Turfan believed that the "infidel Kalmuks" (Dzungars) were the ones who built Buddhist monuments in their area, in opposition to the current academic theory that it was their own ancestral legacy.
