Tibet emerged in the 7th century as a unified empire, but it soon divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) were 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; most of this area was eventually incorporated into the Chinese provinces of Sichuan and Qinghai. The current borders of Tibet were generally established in the 18th century.[1]Following the collapse of the Qing dynasty in 1912, Qing soldiers were disarmed and escorted out of Tibet Area (Ü-Tsang). The region declared its independence in 1913.
