Kangxi and the three feudatories

01How the three feudatories formed

In the conquest years the Qing bought three Han defectors with princely titles and territories: Wu Sangui in Yunnan (Prince Pingxi), Shang Kexi in Guangdong (Pingnan), and Geng Jingzhong — heir to Geng Zhongming — in Fujian (Jingnan).

The feudatories kept real armies: Wu’s peaked at fifty or sixty thousand, Shang’s and Geng’s about ten thousand each. Money mattered more: they taxed their provinces and monopolized salt and iron, while the court paid them an annual subsidy over twenty million taels — half the empire’s revenue. Three kingdoms in all but name.

02The young emperor’s call

The Kangxi Emperor Xuanye took the throne in 1661 at eight, assumed personal rule in 1667, and in 1669 seized the regent Oboi in a coup. The feudatories now obsessed him: Wu Sangui coined his own money, seized land, and appointed his own officials — offices of the western selection spread across the realm.

The court split: most held that dissolving the feudatories meant war; the finance minister Mi Sihan and the war minister Mingzhu argued for it. In 1673, when Shang Kexi asked to retire to Liaodong leaving his son in place, Kangxi seized the opening and approved the full dissolution. In the seventh month Wu Sangui and Geng Jingzhong tested the water with feigned retirement petitions — and the twenty-year-old emperor, overriding nearly unanimous opposition in the council, ordered all three feudatories dissolved. His reasoning: Wu Sangui has plotted for years; move early, or nurse the ulcer.

The order went out. That eleventh month Wu Sangui killed the Yunnan governor Zhu Guozhi and rose as Grand Marshal for Campaigns, under the banner of reviving Ming and expelling the barbarian.

03Eight years of war

The opening ran against the Qing: Wu’s main force took Guizhou and Hunan; Sichuan, Guangxi, Fujian (Geng) and Guangdong (Shang Zhixin) answered; Wang Fuchen rebelled in Shaanxi — half the empire changed hands. History calls it the Revolt of the Three Feudatories.

Kangxi’s response showed composure beyond his years: punish the ringleaders, pardon the coerced — and split the coalition; trust commanders like Tuhai and Zhao Liangdong; rely on the Han Green Standard armies, not the Manchu banners alone; and field new cannon cast under the Jesuit Ferdinand Verbiest in siege warfare.

The tide turned step by step: 1676 Wang Fuchen surrendered, then Geng; 1677 Shang Zhixin; 1679 Hunan recovered; in the tenth month of 1681 Qing troops stormed Kunming, where Wu Shifan — grandson of Wu, who had died of illness at Hengzhou in 1678 — killed himself. Eight years of war ended.

04What the war settled

The Feudatory War was Kangxi’s true coming of age, and its consequences ran deep. Militarily the feudatories were abolished and military power recentralized; the Green Standard system set. Politically Yunnan and Guizhou came under directly appointed governors; Taiwan was made prefectures and counties (1684, after Shi Lang’s conquest of 1683). Diplomatically the Treaty of Nerchinsk followed in 1689: the governance frame of a multiethnic state took shape.

The war also left a tangled narrative: Wu Sangui rose under the banner of reviving Ming — the same man who had strangled the last Ming emperor with a bowstring. The mismatch between slogan and biography warns us to read the early Qing from several standpoints, not only the victor’s proclamation. The war’s real meaning was a repricing of center–frontier relations: what it settled was not three feudatories’ fates but the structure of governing China for the next two centuries.
