The annexation of Tibet by the People's Republic of China, called the "Peaceful Liberation of Tibet" by the Chinese government, and the "Chinese invasion of Tibet" by the Central Tibetan Administration and the Tibetan people, was the process by which the People's Republic of China (PRC) gained control of Tibet. The Government of Tibet and the Tibetan social structure remained in place in the Tibetan polity under the authority of China until the 1959 Tibetan uprising, when the Dalai Lama fled into exile and after which the Government of Tibet and Tibetan social structures were dissolved.
