Tubo is the first political power established in Tibetan history and an ancient kingdom on the Qinghai-Tibet Plateau. The regime established by ancient Tibetans in the 7th-9th century lasted for more than 200 years, from Songzan Gambu to Mir.

It is called "bod" in Tibetan and Tibetan, which is the name of ancient Tibetans. Vomiting is a "big" sound turn in Chinese. Most people think that Tubo is a transliteration of "Dafan". The word Tubo first appeared in the historical records of the Tang Dynasty in China. The Wang Shi system of Xibuye, the predecessor of the Tubo Dynasty, rose in the Yalong River basin, which was the center of plateau agriculture at that time, so it was called "Fanyu". The universal system of learning to supplement wild praise, taking place names as the title, became "Tubo Zanpu". During the Tubo period, all the land under the jurisdiction of Zangbo Songzan Gambo was called "Tubo".

In the 6th century, it rose in Zedang, Shannan region of Tibet.

The Yalong River system of Tibetan ancestors in poverty-stricken areas has developed from tribal alliance to slavery regime. Its leaders, Dabney Sai and Bao Rilunzan, gradually extended their influence to the Lhasa River basin. At the beginning of the 7th century, Songzan Gambu, son of Nanri Lunzan, conquered the ancient Qiang people Supi (now northern Tibet, southwest Qinghai) and Toarey Yang (now northern Tibet) by force, moved the first city to Luoxue (now Lhasa), and formally established the Tubo dynasty.
