An Lushan Rebellion

An Lushan Rebellion. The An Lushan Rebellion was a devastating civil war during the mid-Tang dynasty, instigated by the military governor An Lushan against the ruling House of Li. Lasting from 755 to 763, the conflict caused catastrophic population loss, severely weakened the central government's authority, and precipitated the dynasty's long-term decline. It marked a pivotal shift from the prosperous Kaiyuan era to an age of endemic regional warlordism.

Background and causes

The rebellion's roots lay in the structural military reforms and political intrigues of the mid-8th century. Following victories over the Second Turkic Khaganate and the Tibetan Empire, the Tang court, under Emperor Xuanzong, replaced the Fubing system with a professional army under regional military governors. An Lushan, a general of Sogdian and Göktürk descent, accumulated immense power by commanding the Fanyang, Hedong, and Pinglu circuits near modern Beijing. Intense court rivalries, particularly between Chancellor Yang Guozhong and An Lushan, along with the emperor's preoccupation with Yang Guifei, created a crisis. The central government's weakening grip, combined with An Lushan's personal ambition and control over ethnically mixed Tiele, Khitan, and Xi troops, made revolt inevitable.

Outbreak and major campaigns

The rebellion erupted on 16 December 755, when An Lushan declared himself emperor of the new Yan dynasty in Fanyang. His forces swiftly moved south, capturing the eastern capital Luoyang by early 756. A pivotal Tang defeat at the Battle of Yongqiu failed to halt the advance, and Yan troops breached the Tong Pass, forcing Xuanzong to flee Chang'an for Chengdu. During the Flight to Shu, imperial guards mutinied at Mawei Station, demanding the deaths of Yang Guozhong and Yang Guifei. Xuanzong's son, Suzong, declared emperor at Lingwu, organized the loyalist resistance with generals Guo Ziyi and Li Guangbi, and enlisted support from the Uyghur Khaganate. The crucial Battle of Suiyang and the Uyghur-assisted recapture of Chang'an and Luoyang in 757 turned the tide. The war descended into a protracted stalemate following the assassinations of An Lushan and his successor An Qingxu, and the rise of Shi Siming and his son Shi Chaoyi. The conflict finally ended in 763 with the defeat of the last Yan remnants.

Impact on the Tang dynasty

The rebellion's demographic and economic impact was catastrophic, with census records suggesting a loss of up to two-thirds of the registered population in affected regions due to warfare, famine, and disease. The Tang treasury, once flush from the Grand Canal trade, was exhausted, forcing the court to cede fiscal and administrative autonomy to provincial Jiedushi. This effectively ended the uniform Equal-field system and centralized taxation, empowering regional military governors. The government's reliance on foreign troops, notably the Uyghur Khaganate and the Tibetan Empire, backfired as the latter exploited the chaos to raid Hexi and even briefly capture Chang'an in 763. The authority of the House of Li was permanently diminished, shifting political power from the imperial court to rival warlords.

Aftermath and legacy

In the immediate aftermath, the Tang court never restored its former hegemony. The Fanzhen system became entrenched, leading to periodic revolts such as the Huigu Fengchen and the Li Huaiguang rebellion. The weakened center could not prevent the Tibetan Empire from seizing large territories or stop the semi-autonomous Heavenly Kingdom of Jing in Hebei. Militarily, the dynasty became dependent on a patchwork of loyalist governors and foreign mercenaries. This decentralization set a precedent for the eventual Five Dynasties and Ten Kingdoms period. The rebellion is traditionally seen as the major turning point in Tang history, ending its golden age and initiating a long decline characterized by Eunuch domination of the imperial court and chronic provincial instability.

Cultural depictions

The tragedy of the rebellion profoundly influenced Chinese literature and historiography. It is a central backdrop in the poetry of Du Fu, whose works like "Lament of the Frontier" chronicle the societal devastation. Bai Juyi's famous narrative poem "Song of Everlasting Sorrow" romanticizes the love between Xuanzong and Yang Guifei and the chaos of the revolt. The rebellion is extensively detailed in the official history Old Book of Tang and Sima Guang's Zizhi Tongjian. It has been adapted in numerous operatic traditions, including Peking opera, and continues to be a subject in modern Chinese cinema and television dramas.
