The Case of Yangzhou Chief Historian Liu Zhan Impeaching the Jiangdu Magistrate for Accepting Bribes and Perverting the Law in the First Year of the Shangyuan Era

In the first year of the Shangyuan era (760 AD) during the Tang Dynasty, Liu Zhan, the Chief Historian (Zhangshi) of Yangzhou, formally impeached the county magistrate of Jiangdu. Liu accused the magistrate of accepting bribes from litigants and intentionally perverting the course of justice, leading to wrongful and unjust verdicts that severely damaged public trust in the legal system. The imperial court took the impeachment seriously and ordered a thorough investigation by judicial authorities. After examining the evidence and questioning relevant parties, the charges of bribery and malfeasance were confirmed. According to the Tang Code, the magistrate was convicted under the severe statute of “accepting bribes to subvert the law.” He was consequently sentenced to capital punishment (strangulation). Although the accuser Liu Zhan later notoriously rebelled against the Tang court, at the time of the impeachment his action demonstrated the vigilance of the supervisory system over local officials. The case underscored the Tang central government’s uncompromising stance against corruption in local administration.

The Jiangdu County Magistrate was found guilty of the charge of accepting bribes to pervert the law. In accordance with the statutes of the Tang Code, he was sentenced to death by strangulation and was promptly executed, with his illicit gains confiscated.

The central dispute revolved around whether the Jiangdu magistrate had truly accepted bribes and subverted justice, or if Liu Zhan's impeachment was driven by ulterior personal or political motives, especially given Liu's subsequent rebellion. Additionally, there was legal scrutiny regarding the correct application of the Tang Code’s harsh penalties for judicial bribery, and debates over the reliability of the evidence presented against the local magistrate.

The case sent a strong deterrent message to local officials throughout the empire, reinforcing the strict anti-corruption norms of the Tang legal system. It strengthened the oversight role of regional supervisors like the Changshi and was later cited in legal compilations as a prominent example of judicial accountability. Although Liu Zhan’s later insurrection cast a retrospective political shadow over the case, the legal proceedings themselves remained a benchmark for impeaching and punishing corrupt magistrates in subsequent Chinese dynasties.
