Hu Weiyong Case (1380): The Hongwu Emperor's Great Purge

The Hu Weiyong case began in January 1380, when the Hongwu Emperor, founder of China’s Ming dynasty, executed his chancellor Hu Weiyong on charges of plotting rebellion. The emperor then abolished the office of chancellor, which had existed in some form for centuries, and took personal control of the government. Investigations linked to the case continued for a decade and are said to have cost around 30,000 lives.

Background

Hu Weiyong came from Dingyuan in Anhui, the home region of the emperor Zhu Yuanzhang, and joined his forces in the 1350s, during the Red Turban Rebellion against the Yuan (see also Hongwu Emperor and the founding of the Ming). He belonged to a group of officials from the Huaixi region associated with Li Shanchang, the emperor’s senior civil adviser.

In the early Ming state, the Secretariat (Zhongshu sheng), headed by chancellors, oversaw the six ministries of Personnel, Revenue, Rites, War, Justice and Works. Hu became a chancellor in 1373 and senior chancellor in 1377. He gained a reputation for arrogance, for promoting his allies and for screening reports before they reached the throne. Rumours even claimed that he had arranged the poisoning of the adviser Liu Ji, who died in 1375; this was never proven.

The fall of Hu Weiyong

The crisis began in late 1379, when envoys from Champa, a kingdom in what is now central and southern Vietnam, arrived with tribute but were not promptly reported to the emperor. The furious Hongwu Emperor blamed the senior ministers. Investigations widened, and early in 1380 Hu was accused of conspiring with other officials to seize power.

Hu Weiyong was executed in January 1380, together with the censor-in-chief Chen Ning, the official Tu Jie and many members of their families and circles. The emperor immediately announced the abolition of the Secretariat. The six ministries would report directly to him, and the Chief Military Commission was split into five commissions so that no single general controlled the army.

A decade of purges

The case did not end with Hu’s death. Over the following years the charges were expanded. Officials claimed that Hu had sought help from Japan and from the Mongol Northern Yuan, and anyone thought to have been his associate could be arrested. In 1382 the emperor created the Embroidered Uniform Guard (Jinyiwei), a secret police force that later handled such investigations.

In 1390 the case reached its peak. Li Shanchang, then aged 76 and long retired, was forced to commit suicide, and some 70 members of his household were put to death. The emperor published a record of the “treacherous faction” to justify the killings. Even the respected scholar Song Lian, the tutor of the crown prince, had been sent into exile after his grandson was implicated, and he died on the way in 1381. Ming histories put the total number of victims at about 30,000, a figure historians treat as approximate.

Consequences

The Hongwu Emperor wrote into his Ancestral Injunctions that no successor should ever restore the post of chancellor, and that any official who proposed it should be executed. As a result, Ming emperors had to handle an enormous volume of paperwork themselves. Over time they came to rely on grand secretaries, at first modest advisers, who by the 15th century formed an informal but powerful Grand Secretariat.

A second great purge followed in 1393, when the general Lan Yu was executed and some 15,000 people were reportedly killed. Together, the two cases eliminated most of the founding generation of Ming officials and generals.

Historians’ views

Modern historians, beginning with Chinese scholars such as Wu Han in the 1930s, have questioned whether Hu Weiyong ever plotted a coup. The surviving accounts were compiled by officials working under the emperor who ordered the killings, and the most dramatic charges appear only years after Hu’s death. Many scholars see the case less as a response to a real conspiracy than as a deliberate strike against an office that limited the emperor’s personal power.

Others stress the emperor’s own background and temperament. Zhu Yuanzhang had risen from poverty through years of civil war in which betrayal was common, and he was deeply suspicious of the educated officials and veteran commanders on whom his new state depended. His writings warn repeatedly against ministers who deceive the ruler. The Hu Weiyong case therefore fits a wider pattern of harsh control that also included savage punishments for corruption.

• 1393: the separate Lan Yu case leads to a second great purge.

Why it matters

The Hu Weiyong case transformed Chinese government. By destroying the chancellorship, the Hongwu Emperor concentrated power in the throne to an extent rarely seen before, a pattern that shaped the rest of the Ming and influenced the Qing. The purges also showed how fear and suspicion could turn a single case into a weapon against a whole political elite.
