Xiao Yu (575[1] – 19 July 648[2]), courtesy name Shiwen, posthumously known as Duke Zhenbian of Song, was an imperial prince of the Western Liang dynasty who later became an official under the Sui and Tang dynasties. He served as a chancellor during the reigns of the emperors Gaozu and Taizong in the early Tang dynasty.
Xiao Yu was born in 575, during the reign of his father Emperor Ming of Western Liang, who claimed the throne of Liang dynasty but whose territory, known in history as the Western Liang, was limited to a small amount of territory around his capital Jiangling. Emperor Ming was at that time also a vassal of the much larger Northern Zhou, and received protection from Northern Zhou forces against rival Chen dynasty. In 582, Xiao Yu was created the Prince of Xin'an. He was known for his filial piety.
In or around 582, Xiao Yu's older sister married Yang Guang the Prince of Jin, a son of Sui's founder Emperor Wen of Sui, to be his princess. Xiao Yu followed her to the Sui capital Chang'an, and he became known for studiousness and proper actions there. He was particularly attentive in studying Buddhist sutras and became a devout Buddhist, spending much of his time discussing Buddhism with monks. Displeased with the work Essay on Predestination (辯命論, Bianming Lun), authored by the Liang dynasty author Liu Xiaobiao (劉孝標), he wrote a work entitled, Essay on Non-Predestination (非辯命論, Fei Bianming Lun) intended to refute it. (Only the first paragraph of the preface survives, and it states, "Man is born from heaven and earth. Of course predestination is involved. However, good fortune and ill fortune also depend on man himself. If one believes that it is all predestination, he would be foolish.") The work was praised by the scholars on Yang Guang's staff.
In 585, Emperor Ming died and was succeeded by his oldest son and Xiao Yu's older brother Xiao Cong (as Emperor Jing). In 587, when Emperor Wen summoned Emperor Jing to Chang'an to meet him, Xiao Yu's uncle Xiao Yan (蕭巖) and brother Xiao Huan (蕭瓛), believing that a Sui army sent to Jiangling was intending to attack it, surrendered to Chen. When Emperor Wen heard of this, he abolished Western Liang and annexed its territory, creating Emperor Jing the Duke of Ju. Western Liang was at its end, although its imperial clan members, including Xiao Yu, continued to be treated well by Emperor Wen. In 600, after Yang Guang displaced his older brother Yang Yong as crown prince, Xiao Yu continued to serve on Yang Guang's staff, as a guard commander.
In 604, Emperor Wen died—a death that traditional historians generally believed to be a murder ordered by Yang Guang but admitted a lack of direct evidence—and was succeeded by Yang Guang (as Emperor Yang). Xiao Yu, whose sister Crown Princess Xiao became empress, was made a military recruiting officer. When, at one point, Xiao Yu became suddenly ill, he ordered that no medical treatment be carried out, believing that this would be a good time for him to be relieved from governmental service. However, when Empress Xiao heard this, she visited him and rebuked him, pointing out that this kind of behavior might in fact bring punishment from Emperor Yang. After he recovered, he became more interested in governmental service, and was at one point made the Neishi Shilang (內史侍郎), the assistant head of the legislative bureau of government, and Emperor Yang entrusted him with many secret matters, as Xiao Yu was his brother-in-law. However, later on he was demoted because he often gave suggestions that offended Emperor Yang.
In the fall of 615, Emperor Yang conducted a tour of the northern frontier, exposing himself to a surprise attack by Eastern Turkish (Dongtujue) forces under Shibi Khan, who was angered by various Chinese attempts to weaken his government. The Turks quickly overran most of Yanmen Commandery, but the khan's Chinese wife—an imperial relative who had been married to his predecessor and who had been well treated by the Empress Xiao during an earlier visit—sent warning to the emperor and empress of the attack. The imperial entourage was able to reach the commandery seat at present-day Daixian, Shanxi,[3] where they were besieged by the Turks on September 11.[4][5] Emperor Yang panicked and did not know what to do. Xiao Yu, who had accompanied the emperor, suggested that messengers be sent to Princess Yicheng, as Turkish customs dictated that the khan's wife be in charge of military matters at home while he was away. Princess Yicheng subsequently sent false information to Shibi Khan, stating that the khaganate was under attack from the north, and the khan lifted the siege. After the siege was lifted, Emperor Yang, instead of rewarding Xiao Yu, became embarrassed, stating, "Turkish forces were simply being rebellious and lacked tactical cohesion and would have soon scattered. Just because they did not do so immediately, Xiao Yu was frightened; this is unforgivable." He demoted Xiao Yu to the governorship of Hechi Commandery (河池, in modern Baoji, Shaanxi) and immediately ordered him to get on his way.
When Xiao Yu got to Hechi Commandery, there were agrarian rebels in the mountains, numbering over 10,000, whom the commandery government was unable to control. Xiao Yu reorganized the commandery militia and attacked them, forcing them to surrender. Subsequently, when Xue Ju rebelled at Jincheng Commandery (金城, roughly modern Lanzhou, Gansu) and attacked east, Xiao Yu blocked Xue's path, and Xue was not able to advance further at that point.
In winter 617, the general Li Yuan the Duke of Tang, who had rebelled at Taiyuan earlier that year, captured Chang'an and declared Emperor Yang's grandson Yang You the Prince of Dai emperor (as Emperor Gong). Li Yuan assumed power as regent, and he wrote to Xiao Yu, requesting that Xiao submit. Xiao agreed, and was made the minister of census and created the Duke of Song. In spring 618, during an abortive campaign where Li Yuan sent his sons Li Jiancheng and Li Shimin with an army to the eastern capital Luoyang to try to get Sui officials there to submit, Xiao served on Li Shimin's staff.
Also in spring 618, Emperor Yang was killed at Jiangdu (江都, in modern Yangzhou, Jiangsu) in a coup led by the general Yuwen Huaji. When the news reached Chang'an, Li Yuan had Yang You yield the throne to him, establishing Tang dynasty as its Emperor Gaozu. He made Xiao Yu Neishi Ling (內史令), the head of the legislative bureau of the government (內史省, Neishi Sheng) and a post considered one for a chancellor, and he entrusted Xiao with some of the most important matters of state. Whenever Emperor Gaozu held imperial gatherings, he would allow Xiao to sit next to him, and particularly, because Xiao had married a member of the Dugu clan, from which Emperor Gaozu's mother Lady Dugu also came, Emperor Gaozu referred to him endearingly as "Master Xiao." Xiao took the matters of state seriously and was not afraid of offending others in offering suggestions, and people feared him. When Li Shimin was made the governor of the capital prefecture Yong Prefecture (雍州, i.e., Chang'an and its surrounding counties), Xiao was given the additional title of commandant of Yong Prefecture. In 619, he and Pei Ji were in charge of interrogating one of the major initial contributors to Emperor Gaozu, Liu Wenjing, who had been arrested on suspicion of treason. Both he and Li Gang (李綱), as well as Li Shimin, tried to intercede on Liu's behalf, but Emperor Gaozu nevertheless executed Liu on Pei's recommendations. Later, after the legislative bureau was renamed Zhongshu Sheng (中書省) in 620, Xiao Yu remained its head with the new title of Zhongshu Ling (中書令). Per Xiao's recommendations, Emperor Gaozu made Feng Deyi Zhongshu Ling as well, sharing the position with Xiao. In 621, he was similarly put in charge, along with Pei and Chen Shuda, of interrogating Li Zhognwen (李仲文) the Duke of Zhenxiang, who was also charged with treason, and while Xiao's recommendations were unclear, Li Zhongwen was also executed.
At times, when Emperor Gaozu issued edicts, he wanted the legislative bureau to promulgate them quickly, but Xiao did not do so. When Emperor Gaozu rebuked him, Xiao pointed out that during Emperor Yang's reign, the edicts were issued quickly, and while officials had valid reservations, they did not dare to speak against it. He wanted the edicts to be issued only after greater examination, and so was not issuing them as quickly. Emperor Gaozu agreed. Meanwhile, as Xiao's property was initially seized by Emperor Gaozu when he first entered Chang'an to be awarded to the military officers with accomplishments, Emperor Gaozu returned the property to Xiao. Xiao divided the property and distributed it to his clan members, only keeping the family shrine so that he could sacrifice to the ancestors. After Li Shimin destroyed a major rival, Wang Shichong, the emperor of Zheng, in 621, Xiao, who served under Li Shimin during the campaign and was credited with some of the strategies (as well as charged with collecting the Sui imperial treasury stores at the Zheng capital Luoyang), was given 2,000 additional households as part of his fief and made one of the deputy heads of the important executive bureau of government (尚書省, Shangshu Sheng), Shangshu Pushe, still considered a chancellor position. As Shangshu Pushe, Xiao was considered diligent but biased, as well as harsh, and he did not have as good of a reputation.
In 626, when Fu Yi (傅奕) the director of the imperial astronomical observatory, a Confucian, submitted a proposal to ban Buddhism on the grounds that Buddhism was leading to corruption and abuses within the government, Xiao, as a devout Buddhist, debated with Fu earnestly before Emperor Gaozu. He was unable to prevail over Fu in the debate, and Emperor Gaozu issued an edict severely limiting the number of Buddhist temples, although the edict did not appear to be seriously carried out.
Later in 626, Li Shimin, then in an intense rivalry with Li Jiancheng, who had been made crown prince as the oldest son, feared that Li Jiancheng was about to kill him. He submitted a secret petition to Emperor Gaozu accusing Li Jiancheng and another brother, Li Yuanji the Prince of Qi, who supported Li Jiancheng, of committing adultery with Emperor Gaozu's concubines and plotting to kill him. Emperor Gaozu, shocked by the accusations, summoned Xiao, along with Pei and Chen, to prepare to act on the accusations the next morning. Meanwhile, Li Shimin set an ambush for Li Jiancheng and Li Yuanji at Xuanwu Gate outside Emperor Gaozu's palace, and when Li Jiancheng and Li Yuanji approached Xuanwu Gate in the morning, Li Shimin killed them, and then sent his general Yuchi Gong into the palace, claiming to be protecting Emperor Gaozu. Emperor Gaozu, realizing how serious the situation was, asked Pei, Xiao, and Chen for advice, and Xiao and Chen advised him to create Li Shimin crown prince to placate him. Emperor Gaozu did so, and two months later passed the throne to Li Shimin, who took the throne as Emperor Taizong.
Initially, Xiao Yu remained chancellor, but was soon conflicting with Feng Deyi, who was also chancellor, as Shangshu Pushe (by this point heads of the executive bureau, as Li Shimin had been head of the executive bureau, but his title Shangshu Ling had thus become a title that his subjects did not dare to take), over Feng's frequent changes of things that they had already agreed on, as well as some other new chancellors that Emperor Taizong had trusted and commissioned, including Fang Xuanling and Gao Shilian. In anger, Xiao submitted a secret petition to Emperor Taizong denouncing Feng, but the petition was inartfully written, offending Emperor Taizong. Meanwhile, an incident occurred where Xiao and Chen Shuda argued before Emperor Taizong, and both were removed from their posts. In summer 627, however, after Feng's death, Emperor Taizong again made Xiao Shangshu Pushe. Later that year, Emperor Taizong discussed attacking Eastern Tujue, which Xiao favored, but Zhangsun Wuji opposed, and therefore Emperor Taizong did not carry out the attack. However, when Emperor Taizong asked Xiao how he felt that the life of the dynasty could be extended, Xiao suggested enfeoffing the imperial princes, and Emperor Taizong agreed and began considering doing so. Around the new year 628, Xiao was again removed from his position, for reasons not stated in history, although in spring 630 he was made a de facto chancellor as imperial censor. Later that year, he accused the general Li Jing, after defeating and capturing Eastern Tujue's Jiali Khan Ashina Duobi, of allowing his soldiers to plunder Tujue's treasures, but Emperor Taizong took no actions against Li Jing, on account of Li Jing's great accomplishment. Meanwhile, Xiao continued to be arrogant and harsh and was again not getting along with the other chancellors. It was said that when Fang, Wei Zheng, and Wen Yanbo had minor faults, Xiao submitted accusations against them which Emperor Taizong did not act on, and Xiao became displeased from it. In fall 630, Emperor Taizong made him an advisor to his son and crown prince Li Chengqian, no longer a chancellor.
In 634, Emperor Taizong commissioned 13 officials to examine the circuits in the empire, to see whether the local officials were capable, to find out whether the people were suffering, to comfort the poor, and to select capable people to serve in civil service. Xiao Yu was made the examiner of Henan Circuit (河南道, roughly modern Henan and Shandong), but on his mission, he overly punished an official who did not listen to the people under him about their suffering by putting him in a block, causing that official's death. Emperor Taizong, however, did not punish him. In 635, Emperor Taizong again made him de facto chancellor, once stating:
He also wrote a poem to Xiao Yu, including these two lines:
He further stated to Xiao, "Your faithfulness and honesty cannot be exceeded even by the holy men of old times. However, your overzealousness to distinguish good and bad sometimes makes you difficult to tolerate."
In 643, Emperor Taizong commissioned 24 portraits at Lingyan Pavilion to commemorate the contributions of the 24 great contributions to Tang dynasty. Xiao's was one of the portraits. Later that year, Li Chengqian, fearful that Emperor Taizong was considering replacing him with his younger and more favored brother Li Tai the Prince of Wei, plotted with the general Hou Junji to overthrow Emperor Taizong. When the plot was discovered, Emperor Taizong commissioned Xiao, along with Zhangsun, Fang, Li Shiji, and officials from the supreme court, the legislative bureau, and the examination bureau, to investigate. As a result of the investigation, Hou and many other conspirators were ordered to commit suicide or were executed, while Li Chengqian was reduced to commoner rank. Soon thereafter, Emperor Taizong, believing that Li Tai had played a role in Li Chengqian's downfall, created another son, Li Zhi the Prince of Jin, crown prince, instead of Li Tai, and Xiao was made a senior advisor of the new crown prince. Xiao was given a newly created title for a de facto chancellor as well, Tong Zhongshu Menxia Sanpin (同中書門下三品). In 645, when Emperor Taizong commanded a major campaign against Goguryeo, he put Xiao in charge of Luoyang as well as the logistics of shipping supplies to the frontline.
In 646, Xiao was again in discord with the other chancellors, going as far as accusing Fang of factionalism bordering on treason. Emperor Taizong was also displeased with Xiao over his requesting to become a Buddhist monk at one point around this time and then changing his mind. In winter 646, he issued an edict extensively accusing Xiao of being overly obsessed with Buddhism—citing Xiao's ancestor Emperor Wu of Liang and Emperor Wu's son Emperor Jianwen of Liang as examples that Xiao was falling into the traps of. He demoted Xiao to the post of prefect of Shang Prefecture (商州, roughly modern Shangluo, Shaanxi), but also cancelled Xiao's title as Duke of Song. In 647, however, Emperor Taizong recalled Xiao to be an imperial advisor (but not chancellor) and restored his title of Duke of Song.
In 648, while accompanying Emperor Taizong at Yuhua Palace (玉華宮, in modern Tongchuan, Shaanxi), Xiao grew ill and died. The ministry of ceremonies suggested, as a posthumous name, De (德, meaning "virtuous"), while the executive bureau suggested Su (肅, meaning, "solemn"). Emperor Taizong, however, disagreed with both, stating that posthumous names should be particularly reflective of people's characters, and he chose Zhenbian (貞褊, meaning "honest but harsh") instead.
