Biography
Family Background and Early Life
Li Ding was born in Yangzhou in 1028, the sixth year of the Tiansheng era. The surviving sources say little about his family background, recording only that he did not come from a prominent official household but from an ordinary scholar family. Li Ding was intelligent and studious from childhood and progressed smoothly through the examination system. In 1057, the second year of Jiayou, he passed the jinshi examination at the nominal age of thirty. That year's examination was presided over by Ouyang Xiu and became famous for producing numerous talented men; Su Shi, Su Zhe, Zeng Gong, and others passed in the same cohort.
After receiving the jinshi degree, Li Ding began his official career as county commandant of Dingyuan. During the Jiayou era (1056–1063), he successively held subordinate local posts in Qizhou, Mingzhou, and elsewhere. He was known in local office for efficiency and pragmatism and accumulated administrative experience. The real turning point in his career, however, came after the introduction of the New Policies of Wang Anshi.
Entry into Court and the New Policies
In 1069, the second year of Xining, Wang Anshi became a vice chief councillor and began implementing the New Policies. Li Ding actively supported the reform program and won Wang Anshi's appreciation. In 1070, the third year of Xining, Wang Anshi recommended Li Ding for appointment as Left Attendant to the Heir Apparent and probationary Investigating Censor. This appointment triggered a well-known dispute involving three drafting officials.
At the time, Song Minqiu, Su Song, and Li Dalin, all serving as drafters of edicts, believed Li Ding's unusually rapid promotion violated institutional norms and refused to draft the appointment edict. They returned the drafting order and declined to implement it. Emperor Shenzong repeatedly sent officials to press them, but the three maintained their position. In the end, Song Minqiu and the others were dismissed and Li Ding took office. The episode caused a major controversy and became one of the early flashpoints of the conflict between reform and conservative factions. Li Ding was thereafter regarded as a firm supporter of the New Policies and became a target of conservative criticism.
Not long after the incident, Li Ding was impeached and sent out of the capital to govern Haizhou. In 1072, the fifth year of Xining, he returned to court and entered the Remonstrance Bureau, again moving into the political center. Over the next several years he served in the Drafting Office, the Remonstrance Bureau, and other institutions, gradually becoming an important member of the New Policies faction.
Censor-in-Chief and the Crow Terrace Poetry Trial
By 1079, the second year of Yuanfeng, Li Ding had risen to Censor-in-chief. That year he took a leading role in investigating the famous Crow Terrace Poetry Trial of the Northern Song.
Su Shi, then serving as prefect of Huzhou, had included phrases in his “Memorial of Thanks upon Appointment to Huzhou” that were accused of ridiculing government policy. Censors He Zhengchen, Shu Dan, and others impeached Su Shi, and Li Ding, as Censor-in-chief, was responsible for handling the case. Li Ding submitted a memorial accusing Su Shi of harboring malicious intentions and resentment toward the ruler and cited passages in Su's poetry said to ridicule the New Policies. Su Shi was arrested and imprisoned in the Censorate, where he suffered harsh treatment.
The Crow Terrace Poetry Trial lasted several months. It concluded in the twelfth month of the same year, when Su Shi was demoted to the post of assistant military commissioner of Huangzhou. The case implicated many people, including Wang Shen, Wang Gong, and Su Zhe. As the principal official responsible for the proceedings, Li Ding took a severe approach, and later literary works often portrayed him as sinister and harsh.
High Office and Fall from Power
After the Crow Terrace Poetry Trial, Li Ding's career continued to advance. In 1082, the fifth year of Yuanfeng, he served on trial appointment as Minister of Personnel. He later held major posts including Hanlin Academician and drafter of edicts. In 1085, the eighth year of Yuanfeng, Emperor Shenzong died, producing a fundamental political change.
After Emperor Zhezong succeeded, Empress Dowager Gao ruled as regent and the conservative faction returned to power. In 1086, the first year of Yuanyou, Li Ding was demoted to govern Suizhou because of his association with the New Policies faction. In 1087, the second year of Yuanyou, he was further demoted to superintendent of Dongxiao Palace. He died in exile the same year at the nominal age of sixty.
