Yarkent Khanate
The most common name for Xinjiang used by independence advocates is "East Turkestan" (or "Uyghurstan"). There is no consensus among secessionists about whether to use "East Turkestan" or "Uyghurstan"; "East Turkestan" has the advantage of also being the name of two historical political entities in the region, while Uyghurstan appeals to modern ideas of ethnic self-determination. Uyghurstan is also a difference in emphasis in that it excludes more peoples in Xinjiang than just the Han, but the "East Turkestan" movement is still a Uyghur phenomenon. The name "East Turkestan" is not currently used in an official sense by most sovereign states and intergovernmental organizations. Another proposed alternative is "Yarkand" or "Yarkent," which harkens back to the Yarkent Khanate, a powerful Uyghur state in the 16th and 17th centuries.
