The Tibetan Empire was created by Songtsen Gampo, who unified the Tibetan plateau in the early seventh century, and lasted until the assassination of Langdarma in 842. It conquered the Tarim Basin cities, Nepal and parts of Yunnan and Gansu, fought the Tang dynasty for 150 years and captured Chang'an for a fortnight in 763. It adopted Buddhism, created the Tibetan script and made a peace treaty with China in 821 that still stands carved outside the Jokhang temple. It collapsed into a century of fragmentation after 842.

Songtsen Gampo

Songtsen Gampo (reigned about 618-649) completed the unification begun by his father, subdued the Zhangzhung kingdom, married Nepalese and Chinese princesses, and sent a minister to India to devise a Tibetan alphabet. Tibet's alliance and rivalry with the Tang began at once: the Chinese princess Wencheng arrived in 641, and Tibetan raids on the Tang frontier followed.

Empire at its height

Under Trisong Detsen Tibet took advantage of the An Lushan rebellion to seize Gansu and, in 763, briefly occupy Chang'an and install a puppet emperor. Tibetan armies contested the Tarim Basin with the Tang, the Uyghurs and the Abbasids, reaching the Pamirs and the Oxus. Trisong Detsen made Buddhism the state religion, invited the Indian masters Padmasambhava and Shantarakshita, and founded Samye monastery in 779.

Peace and collapse

The treaty of 821-822 fixed the border with China 'so that Tibetans shall be happy in Tibet and Chinese in China'. But the cost of empire, tension between Buddhist clergy and the old nobility and Bon religion, and a succession dispute after King Langdarma was killed by a Buddhist monk in 842 broke the state. The Uyghurs' fall in 840 and Tang recovery of Gansu in 848 stripped away the empire's edges, and Tibet dissolved into local principalities.

  3. The 821 treaty pillar outside the Jokhang is one of the oldest bilingual treaties still standing where it was erected.
