The Tibetan people have their own history, culture, language and religion, but they do not have the main thing - the state. Tibetans are almost completely located in China. Tibet lost its independence in 1949, when the Chinese "liberated" Tibetans from the imperialists.
The Tibetan government is acting now, but in exile - its headquarters headed by Lobsang Sangay is located in the north of India. The government has its own Constitution - the Charter of the Tibetans is in exile. In 2011 Dalai Lama XIV refused the political authorities and retained the role of the spiritual leader of Tibet.
