Tibet

The Tibetan Empire emerged in the 7th century, but with the fall of the empire the region soon divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) was often at least nominally unified under a series of Tibetan governments in Lhasa, Shigatse, or nearby locations; these governments were at various times under Mongol and Chinese overlordship. The eastern regions of Kham and Amdo often maintained a more decentralized indigenous political structure, being divided among a number of small principalities and tribal groups, while also often falling more directly under Chinese rule after the Battle of Chamdo; most of this area was eventually incorporated into the Chinese provinces of Sichuan

China governs western and central Tibet as the Tibet Autonomous Region while the eastern areas are now mostly ethnic autonomous prefectures within Sichuan, Qinghai and other neighbouring provinces. There are tensions regarding Tibet's political status and dissident groups that are active in exile. It is also said that Tibetan activists in Tibet have been arrested or tortured.
