History The ancient city of Songpan was built during the Tang dynasty and it was later rebuilt during Ming dynasty. Songpan was an important military post. It was also an important economic and trading center for horse and tea exchange between Sichuan, Gansu, Qinghai and Tibet. During Tang rule, it was the border with the Tibetan Empire. Emperor Songtsen Gampo of Tibet tried to invade Tang China through this gate. Emperor Taizong of Tang offered him Princess Wencheng at Songzhou (now Songpan) in 641. According to Tibetan and Chinese legends, Princess Wencheng then brings with her among other things the Jowo statue to the Tibetan Empire. Throughout the Ming dynasty, the Chinese court was troubled by the frequent invasion of the Songpan area. The area was given to a Tibetan lama friendly with the Chinese court to maintain frontier control while leaving it in local hands. In August 1935, led by Mao Zedong and Zhou Enlai, the retreating People's Liberation Army marched through the Songpan Grasslands to advance to the northwestern province.
