Xinjiang Uyghur Autonomous Region, where Uyghurs are the largest ethnicity, mostly concentrated in the south-western Xinjiang. The Xinjiang conflict is an ongoing separatist conflict in China's far-west province of Xinjiang, whose northern region is known as Dzungaria and whose southern region (the Tarim Basin) is known as East Turkestan. Uyghur separatists and independence movements claim that the Second East Turkestan Republic was illegally incorporated by China in 1949 and has since been under Chinese occupation. Uyghur identity remains fragmented, as some support a Pan-Islamic vision, exemplified by the East Turkestan Islamic Movement, while others support a Pan-Turkic vision, such as the East Turkestan Liberation Organization. A third group would like an East Turkestan state, such as the East Turkestan independence movement. While the East Turkistan Government in Exile strives for the restoration of East Turkistan's independence as a secular pluralistic Republic that guarantees freedom and civil liberties for all people. As a result, "[n]o Uyghur or East Turkestan group speaks for all Uyghurs, although it might claim to", and Uyghurs in each of these camps have committed violence against other Uyghurs who they think are too assimilated to Chinese or Russian society or are not religious enough. Mindful not to take sides, Uyghur "leaders" such as Rebiya Kadeer mainly tried to garner international support for the "rights and interests of the Uyghurs", including the right to demonstrate, although the Chinese government has accused her of orchestrating the deadly July 2009 Ürümqi riots. Eric Enno Tamm's 2011 book states that, "Authorities have censored Uyghur writers and 'lavished funds' on official histories that depict Chinese territorial expansion into ethnic borderlands as 'unifications (tongyi), never as conquests (zhengfu) or annexations (tunbing)' " Human rights abuses against Uyghurs in Xinjiang Since 2014, Uyghurs in Xinjiang have been affected by extensive controls and restrictions which the Chinese government has imposed upon their religious, cultural, economic and social lives. In Xinjiang, the Chinese government has expanded police surveillance to watch for signs of "religious extremism" that include owning books about Uyghurs, growing a beard, having a prayer rug, or quitting smoking or drinking. The government had also installed cameras in the homes of private citizens. Further, at least 120,000 (and possibly over 1 million) Uyghurs have been detained in mass detention camps, termed "re-education camps", aimed at changing the political thinking of detainees, their identities, and their religious beliefs. Some of these facilities keep prisoners detained
