HISTORICAL BACKGROUND
During the reign of the seventh-century king, Songtsen Gampo, Tibet was one of the mightiest empires in Central Asia. Tibet, then, had an army of more than 100,000 men and each regiment had its own banner. The banner of the Ya-ru To regiment had a pair of snow lions facing each other, that of Ya-ru Ma a snow lion standing upright, springing upwards towards the sky, and that of U-ru To a white flame against a red background.
This tradition continued until the Thirteenth Dalai Lama designed a new banner and issued a proclamation for its adoption by all the military establishments. This banner became the present Tibetan national flag.
