March 19 (Reuters) - Chinese troops moved in this week to tackle unrest in ethnic Tibetan enclaves in its western provinces after violent protests flared against Chinese rule in the Tibetan capital Lhasa on Friday.
Following is a chronology of some of the main events in modern China-Tibet relations.

Sept 1954: Chairman Mao meets Dalai Lama.
March 1959: Tibetans stage abortive uprising in which thousands are killed after reforms are introduced to end centuries of feudalism. Tibet's god-king, the Dalai Lama, flees to India with an estimated 80,000 followers. He establishes a "government-in-exile" in Dharamsala but no country recognises it.
1965: Tibet Autonomous Region formally established.
1966: China's Cultural Revolution begins. Tibetan Red Guards close monasteries in Tibet, smash Buddhist statues and force monks and nuns to return to secular life.

1979: Rapprochement begins with Dalai Lama's brother, Gyalo Thondup, visiting China at invitation of paramount leader Deng Xiaoping. Trips not publicised in media.
March 1989: Martial law imposed in Lhasa after days of rioting sparked by January death of the 10th Panchen Lama, most senior figure in Tibetan Buddhism after Dalai Lama.
October 1989: Dalai Lama is awarded Nobel Peace Prize.
May 1990: Lhasa lifts martial law. Government-in-exile headed by Dalai Lama disbands to pave way for democracy, announcing elections for 1991.
August 1993: Dalai Lama says at rare news conference he is fighting for Tibet's political autonomy, not independence.
1994: Dalai Lama suspends dialogue with China due to lack of progress.

June 1996: Dalai Lama swears in new Tibetan government-in-exile following elections.
Dec 1998: Dalai Lama says in the Indian city of Patna that he is open for talks with China for mutual agreement "without any precondition, anytime, anywhere".

Dec 1999: Dalai Lama says Tibetans would be satisfied with self-rule but accuses the Chinese of cultural genocide.
Jan 1999: Tibet's third ranked monk, the 14-year-old Karmapa Lama, flees China in a week-long trek across the Himalayas to India and meets the Dalai Lama.
July 2006: China opens Qinghai-Tibet Railway, the world's highest railroad, saying it will help modernise and develop Tibet. Tibet advocacy groups say it is accelerating an influx of Han Chinese and threatens its fragile high-altitude environment.
March 2008: Nearly 100 people are killed in anti-China riots, the government-in-exiled says. But Tibet's top government official puts the death toll at 13 and says they were Han Chinese civilians brutally killed by Tibetan mobs. Unrest spreads to ethnic Tibetan communities in nearby Chinese provinces. International protests condemn the violence, which come five months before Beijing hosts the Olympic Games.
