Li Linfu (; 683 – 3 January 753兩千年中西曆轉換), milk name Genu (), art name Yuetang (), was a Chinese historian, musician, and politician of the Tang dynasty, serving as a chancellor for 18 years (734–752), during the reign of Emperor Xuanzong. His tenure as chancellor was one of the longest in Tang history, and the longest during Emperor Xuanzong's reign.New Book of Tang, vols. 61 , 62, 63 .

Li was known for his flattery of the Emperor and skill in the political scene, which enabled him to remain powerful throughout his lengthy duration as chancellor. His treachery in cutting off all routes for all potential political challengers, including false accusations against other officials and the granting of key military commands to non-Han commanders, were blamed for the deterioration of Emperor Xuanzong's reign,Zizhi Tongjian, vol. 216. which culminated in the An–Shi Rebellion after Li Linfu's death. Emperor Xuanzong himself admitted after the An–Shi Rebellion broke out (when Li had died) that Li was most adept at removing political rivals and being jealous of any potential challengers, a factor which resulted in the Tang administration lacking seriously competent officials during the Tianbao era.

Background It is not known when Li Linfu was born. He was a great-grandson of Li Shuliang (李叔良) the Prince of Changping, who was a cousin of Tang dynasty's founder Emperor Gaozu. Li Linfu's grandfather Li Xiaobin (李孝斌) carried the title of Duke of Huayang and served as a prefectural secretary general. Li Linfu's father Li Sihui (李思誨) served as a military officer at Yang Prefecture (揚州, roughly modern Yangzhou, Jiangsu).New Book of Tang, vol. 70 Li Linfu's mother was a sister of the official Jiang Jiao (姜皎), a close associate of Emperor Gaozu's great-great-grandson Emperor Xuanzong who became prominent during Emperor Xuanzong's reign, carrying the title of Duke of Chu. Li Linfu studied music and was favored by his uncle Jiang.

During Emperor Xuanzong's reign

Before chancellorship During Emperor Xuanzong's reign, when Yuan Qianyao served as a chancellor, Li Linfu was a member of the staff of Emperor Xuanzong's crown prince Li Siqian.As Yuan served as chancellor from 720 and 729—and Li Linfu's recommendation by Yuwen Rong was in 726, this event must have occurred between 720 and 726. See Old Book of Tang, vol. 98 and New Book of Tang, vol. 127 . Yuan had been recommended by Jiang Jiao at the start of his career and had had his grandnephew Yuan Guangcheng (元光乘) marry Jiang's sister. Because of these relations, Yuan's son Yuan Jie (源絜) relayed a plea from Li Linfu to be made Simen Langzhong (司門郎中), a low level official at the ministry of justice. Yuan Qianyao, however, did not view Li Linfu highly, and commented, using Li Linfu's nickname, "People who are to serve as Lang must have good talent and virtues. Genu is no Lang." Several days later, however, he had Li Linfu promoted among the ranks of Li Siqian's staff members. Li Linfu later served as Guozi Siye (國子司業), the deputy principal of the imperial university.

In 726, the official Yuwen Rong became deputy chief imperial censor (御史中丞, Yushi Zhongcheng). Yuwen was friendly with Li Linfu, and therefore recommended Li Linfu to serve as a colleague; Li Linfu was thus made a deputy chief imperial censor as well, and later successively served as deputy ministers of justice (刑部侍郎, Xingbu Shilang) and civil service affairs (吏部侍郎, Libu Shilang). At that time, Emperor Xuanzong's favorite concubine Consort Wu dominated the palace, and her sons Li Mao (李瑁) the Prince of Shou and Li Qi (李琦) the Prince of Sheng were Emperor Xuanzong's favorite sons, diverting favor away from Li Siqian (whose name had been changed to Li Ying, by that point). Li Linfu was friendly with many important eunuchs, and through them informed Consort Wu that he was willing to support Li Mao to try to supplant Li Ying. Meanwhile, Li Linfu had also been having an affair with the wife of the chancellor Pei Guangting, who was a daughter of Wu Sansi, a deceased nephew of Emperor Xuanzong's grandmother Wu Zetian and a relative of Consort Wu. After Pei died in 733,Old Book of Tang, vol. 84 .New Book of Tang, vol. 108 . Lady Wu requested that the powerful eunuch Gao Lishi, who had served Wu Sansi at one point, to recommend Li Linfu to replace Pei. Gao did not dare to make the recommendation, but when Emperor Xuanzong was set to name Han Xiu chancellor, Gao leaked this information to Lady Wu first, who then told Li Linfu. Li Linfu submitted a petition endorsing Han, who became grateful. When Han subsequently had conflicts with fellow chancellor Xiao Song, he recommended Li Linfu to serve as chancellor, and Consort Wu was also speaking on Li Linfu's behalf. Emperor Xuanzong did not make him chancellor immediately, but made him Huangmen Shilang (黃門侍郎), the deputy head of the examination bureau of government (門下省, Menxia Sheng) and favored him more.

As chancellor In 734, Li Linfu was made the minister of rites (禮部尚書, Libu Shangshu) and was further given the designation Tong Zhongshu Menxia Sanpin (同中書門下三品), making him a chancellor de facto, serving alongside Pei Yaoqing and Zhang Jiuling. By 736, he, who gained further favor from Emperor Xuanzong by flattering the emperor, was in serious conflict with the blunt Zhang, over a number of matters:

In fall 736, when Emperor Xuanzong was at Luoyang, he had set to return to Chang'an on March 7, 737.兩千年中西曆轉換 However, at that time, an incident occurred where there were strange apparitions appearing in the Luoyang Palace, and Emperor Xuanzong did not want to stay at Luoyang. On or right before November 9, 736,兩千年中西曆轉換 he summoned the chancellors to ask them whether he could depart for Chang'an immediately. Pei and Zhang, pointing out the fact that it was harvest season and that the imperial train would interfere with harvest, requested a one-month delay. After Pei and Zhang exited, however, Li Linfu remained personally and stated his agreement with the departure, arguing that the farmers could be compensated by relieving their taxes. Emperor Xuanzong was pleased and immediately departed for Chang'an. Emperor Xuanzong was, then, impressed with Niu Xianke, the military governor (节度使, jiedushi) of Shuofang Circuit (朔方, headquartered in modern Yinchuan, Ningxia), wanted to make him the minister of defense. Zhang, who pointed out that Niu was not well-learned and had started from the ranks of low-level administrators—contrary to the Tang tradition of going through the imperial examinations—opposed, and then further opposed the creation of a title. Eventually, despite Zhang's opposition, Emperor Xuanzong, with concurrence from Li Linfu, created Niu the Duke of Longxi. Li Linfu was trying to have Emperor Xuanzong make Li Mao crown prince to replace Emperor Xuanzong's Li Ying, who had long lost Emperor Xuanzong's favor and who had offended Emperor Xuanzong and Consort Wu over an incident where he and his brothers Li Yao (李瑤) the Prince of E and Li Ju (李琚) the Prince of Guang privately complained about how Emperor Xuanzong had lost favor for their mothers. With Zhang strenuously opposing such a move, Li Ying remained in his position. The deputy minister Xiao Jiong (蕭炅), whom Li Linfu recommended, was demoted on the suggestion of Zhang and Zhang's friend Yan Tingzhi (嚴挺之), who further offended Li Linfu by refusing to meet with him. Soon thereafter, there was an incident where Wang Yunyan (王元琰), the husband of Yan's ex-wife, was accused of corruption. Yan tried to intercede on Wang's behalf, and this was discovered.

Li Linfu thus made accusations to Emperor Xuanzong that Zhang and Pei were engaging in factionalism. Around the new year 737, Emperor Xuanzong removed Pei and Zhang from their chancellor posts, making them Chengxiang (丞相)—the heads of the executive bureau of government (尚書省, Shangshu Sheng) instead, posts not considered chancellor posts. Niu was made chancellor to replace them, serving with Li Linfu, who was given the office formerly held by Zhang, Zhongshu Ling (中書令), the head of the legislative bureau (中書省, Zhongshu Sheng). This was often viewed by traditional historians as the turning point of Emperor Xuanzong's reign, which up to that point was considered a golden age in Chinese history, toward a path of degeneration. The Song dynasty historian Sima Guang, in his Zizhi Tongjian, for example, commented:Zizhi Tongjian, vol. 214.

It was said that because Niu was recommended by Li Linfu, he followed Li Linfu's directions, while Li Linfu discouraged dissent within the government—telling junior officials that they, like imperial horses who would not obey directions, were easily replaceable. When the official Du Jin (杜璡) nevertheless submitted a proposal, Du was immediately sent out of a capital—ostensibly for a promotion, but considered demoted due to his new post's being away. It was further said that Li Linfu held his emotions in check and was difficult to discern; he often used sweet words to please others and then attack them when they were not ready. He endeared those who were close to the emperor, while finding ways to eliminate potential competitors for power. The Chinese proverb "having honey in the mouth and a sword in the belly" (口蜜腹劍, kou mi fu jian), first became idiomatic when used to describe him.Zizhi Tongjian, vol. 215. Republic of China Ministry of Education, Revised Mandarin Dictionary of Terms, Kou Mi Fu Jian .

In 737, after the imperial censor Zhou Ziliang (周子諒) angered Emperor Xuanzong by filing an indictment against Niu and was caned and then exiled, Li Linfu took the opportunity to point out that Zhang had recommended Zhou. As a result, Zhang was demoted out of the capital to serve as a prefectural secretary general.

Also in 737, Consort Wu decided to try to trick Li Ying, Li Yao, and Li Ju. She had a message sent to the three princes, stating, "There are bandits in the palace. Please report at once in armor!" The three princes arrived in full armor, and she thereafter told Emperor Xuanzong, "The three princes are planning treason. Look, they have come in full armor." Emperor Xuanzong had his eunuchs check out the situation, and the three princes were seen in full armor. Yang Hui subsequently accused Li Ying, Li Yao, and Li Ju of treason. When Emperor Xuanzong discussed this with the chancellors, Li Linfu stated, "This is Your Imperial Majesty's family matter. We will not interfere." The three princes were soon reduced to commoner rank and forced to commit suicide. Meanwhile, the deputy chief judge of the supreme court, Xu Jiao (徐嶠) submitted a flattering report to Emperor Xuanzong, pointing out that there were only 58 death sentences handed down for the year and that the reduced number of sentences showed that Emperor Xuanzong's reign was so peaceful that they were not required. Emperor Xuanzong, in turn, credited the chancellors, and created Li Linfu the Duke of Jin and Niu the Duke of Bin. It was also around this time that a revision of the laws, led by Li Linfu, Niu, and the officials in charge of the justice system, was completed.

In 738, Li Linfu was made the deputy military governor of Longyou Circuit (隴右, headquartered in Haidong Prefecture, Qinghai), but did not report to Longyou and remained in the capital as chancellor. He was soon also made the military governor of Hexi Circuit (河西, headquartered in Wuwei, Gansu). Meanwhile, he was repeatedly urging Emperor Xuanzong to create Li Mao crown prince, but Emperor Xuanzong hesitated—with Consort Wu having died in 737. Instead, at Gao's urging, Emperor Xuanzong created an older son, Li Yu the Prince of Zhong crown prince instead.
