History
The Yarlung valley south-east of Lhasa was the cradle of the Tibetan empire. Under Songtsen Gampo in the 7th century it became a major Asian power; his marriages to a Nepalese princess and to the Chinese princess Wencheng are linked by tradition to the founding of the Jokhang and the arrival of Buddhism, and Samye, the first monastery, followed in the 8th century. The empire broke up after 842, and Buddhism revived through schools such as the Sakya, whose lamas ruled Tibet under Mongol Yuan patronage in the 13th and 14th centuries.
Tsongkhapa's Gelug school, founded in the early 1400s, came to dominate, and in 1642 the Fifth Dalai Lama, backed by the Mongol Güshi Khan, became head of the Ganden Phodrang government and began the Potala. From the 18th century the Qing kept representatives and garrisons in Lhasa. A British expedition reached the city in 1904, and after the Qing collapsed the Thirteenth Dalai Lama proclaimed independence in 1913, which almost no country formally recognised; Tibet was de facto independent until 1950.
Chinese troops defeated the Tibetan army at Chamdo in 1950, and in 1951 Tibetan delegates signed the Seventeen Point Agreement affirming Chinese sovereignty; Beijing regards it as valid, while the Dalai Lama later said it was signed under duress. After an uprising in 1959 the Fourteenth Dalai Lama fled to India, where a government-in-exile sits in Dharamsala, and the Tibet Autonomous Region was created in 1965. Beijing describes 1950 as a peaceful liberation; the exile government and many Tibetans describe an invasion. Most monasteries were destroyed during the Cultural Revolution and later partly rebuilt. Protests in 1987–89 and 2008 were followed by tighter controls, and the 2006 railway brought faster development and, exiles say, faster Han migration.
