In Turkistan, the main languages spoken are Kazakh, Uzbek, and Russian. These languages are widely used in different regions of Turkistan due to historical and cultural influences.

Moguls came from turkistan

Western Turkistan ( the republics of Kazakhstan, Kirghizstan, Uzbekistan, Turkmenistan) have a parlimentary government , while East Turkistan (Uyghurstan or Xinjiang) is occupied by China has a communist puppet government with racist policies agaisnt the Uyghur majority and is undergoing genocide to wipe out all the Uyghurs

It is unclear what the question is asking. If it is asking what countries/regions would be part of Turkistan, they would be Turkey, Azerbaijan, Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, and Xinjiang (part of China).

the Population of East Turkistan (Uyghurstan or Xinjiang) is 65 million with 30 milllion Uyghur Turks, 3 million Kazakhs, 540,000 Kirghiz, 248,000 Uzbeks, 98,000 Tatars and 25 million han Chinese immigrants with an 8.6 million Chinese military presence to further the genocide of the Turkistani people of East turkistan! According to Chinese state the population of East Turkistan is about 28 million (which is a lie)
