Tibet has had a tumultuous history, during which it has spent some periods functioning as an independent entity and others ruled by powerful Chinese and Mongolian dynasties.
China sent in thousands of troops to enforce its claim on the region in 1950. Some areas became the Tibetan Autonomous Region and others were incorporated into neighbouring Chinese provinces.
In 1959, after a failed anti-Chinese uprising, the 14th Dalai Lama fled Tibet and set up a government in exile in India. Most of Tibet’s monasteries were destroyed in the 1960s and 1970s during China’s Cultural Revolution. Thousands of Tibetans are believed to have been killed during periods of repression and martial law.
