Cause → Event → Consequence
Nanzhao exploited internal turmoil within the Tang Protectorate General to Pacify the South (Annan) and forged alliances with local tribes, creating an opportunity to challenge Tang authority over the Red River Delta in what is now northern Vietnam.
In early 863, during the reign of Emperor Yizong, Nanzhao forces besieged Songping, the capital of the Annan Protectorate. The siege concluded in a decisive Nanzhao victory, temporarily displacing Tang administration from the region.
Although Nanzhao succeeded in capturing Songping, Tang forces launched a successful counterattack by 866, driving Nanzhao back and restoring Tang control over the Annan Protectorate and the Red River Delta.
