The Tibetan Empire emerged in the 7th century, but with the fall of the empire, this area was soon divided into different areas. The bulk of western and central Tibet Tsang was often at least nominated under a series of Tibetan governments in Lhasa, Shigatse, or nearby places; These governments were often under Mongol and Chinese domination. Thus, Tibetan Mongol and later Nanjing and Beijing had a consensus of the Chinese rulers, which had given proper autonomy to Tibetan leaders.
In Kham and Amado's eastern areas, there is often a more decentralized indigenous political structure, is being divided among many small princely states and tribal groups, while often after the battle of Chamda, more directly falling under Chinese rule; Most of this area was eventually involved in Chinese provinces of Sichuan and Qinghai.
