The Shenlong Coup ended the Wu regime, and Li Xian took the throne. But his weakness, combined with Empress Wei and Wu Sansi's seizure of power, eventually led Crown Prince Li Chongjun to launch a mutiny, plunging Chang'an into chaos. Many princes, nobles, and high officials fled to Liangzhou, where they grew rich through trade, taking advantage of its strategic location at the crossroads of the four regions.
Song Jing, then inspector of Longyou Circuit, was ordered to tour its various prefectures. This became the catalyst for the various forces of the post-Wu era to stir around Liangzhou.
At the same time, a covert mobile force that had pledged allegiance to the Tang during Emperor Taizong's reign was also drawn into the vortex.
