トカラ語
By the mid-9th century, the area had been conquered by the Uyghur Khaganate and the Tocharian languages were fading from use. "Agnideśa" became widely known by the Uyghur Turkic name Karasahr (or Karashar), meaning "black city". The influence of Islam grew, while older religions such as Buddhism and Manichaenism declined.
