The Uyghurs comprise a Turkic-speaking and predominantly Muslim nationality of China, with communities living in the independent republics of Central Asia that date to the 19th century, and now a global diaspora. As in the case of many national histories, the consolidation of a Uyghur nation was an early 20th-century innovation, which appropriated and revived the legacy of an earlier Uyghur people in Central Asia. This imagined past was grounded in the history of a Uyghur nomadic state and its successor principalities in Gansu and the Hami-Turfan region (known to Islamic geographers as “Uyghuristan”). From the late 19th century onward, the scholarly rediscovery of a Uyghur past in Central Asia presented an attractive civilizational narrative to Muslim intellectuals across Eurasia who were interested in forms of “Turkist” racial thinking. During the First World War, Muslim émigrés from Xinjiang (Chinese Turkistan) living in Russian territory laid claim to the Uyghur legacy as part of their communal genealogy. This group of budding “Uyghurists” then took advantage of conditions created by the Russian Revolution, particularly in the 1920s, to effect a radical redefinition of the community. In the wake of 1917, Uyghurist discourse was first mobilized as a cultural rallying point for all Muslims with links to China; it was then refracted through the lens of Soviet nationalities policy and made to conform with the Stalinist template of the nation. From Soviet territory, the newly refined idea of a Uyghur nation was exported to Xinjiang through official and unofficial conduits, and in the 1930s the Uyghur identity of Xinjiang’s Muslim majority was given state recognition. Since then, Uyghur nationhood has been a pillar of Beijing’s minzu system but has also provided grounds for opposition to Beijing’s policies, which many Uyghurs feel have failed to realize the rights that should accord to them as an Uyghur nation.
