Li Jiancheng (Chinese: 李建成; pinyin: Lǐ Jiànchéng; 589 – July 2, 626, formally Crown Prince Yin (Chinese: 隱太子; pinyin: Yǐn Tàizǐ, literally, "the hidden crown prince"), nickname Pishamen (Chinese: 毗沙門; pinyin: Píshāmén;Sanskrit:Vaiśravaṇa), was the first crown prince of the Chinese dynasty Tang Dynasty. He was the oldest son of the founding emperor Emperor Gaozu (Li Yuan) and the crown prince after the founding of the dynasty in 618. Li Jiancheng was murdered by his younger brother, Li Shimin, the Prince of Qin during Xuanwu Gate indident in 626. All of Li Jiancheng's sons were executed and excluded from imperial clan. After Li Shimin took the throne, Li Jiancheng was posthumously created the Prince of Xi (息隐王). Later, he was buried with ceremonies due an imperial prince. In 642, Li Jiancheng's crown prince title was restored as the crown Prince of Yin (隐太子).

Li Jiancheng was born in 589, during the reign of Emperor Wen of Sui. He was the oldest son of Li Yuan the Duke of Tang, a hereditary noble, and Li Yuan's wife Duchess Dou, who was herself the daughter of Dou Yi (竇毅) the Duke of Shenwu and Northern Zhou's Princess Xiangyang. Duchess Dou would subsequently give birth to three of Li Jiancheng's younger brothers -- Li Shimin, Li Xuanba (李玄霸, who died in 614), and Li Yuanji. She also gave birth to a sister of Li Jiancheng's, the eventual Princess Pingyang, although it was not clear whether she was older or younger than Li Jiancheng. At some point, Li Jiancheng received the title of Heir Apparent of Tang.
Participation in Tang's founding
The rebellion against Sui rule
In 616, with rebellions beginning to engulf northern China and frequent Eastern Tujue incursions across the border, Emperor Yang of Sui commissioned Li Yuan to be the commander of Taiyuan, guarding it against both rebels and Eastern Tujue. At that time, Li Yuan took Li Shimin with him to the city Jinyang, which was the administrative center of Taiyuan. As the chief commander of Taiyuan, Li Yuan had to leave his family behind according to law. Li Jiancheng was put in charge of the estate and he was the man of the house of Hedong (河東, in modern Yuncheng, Shanxi) while Li Yuan was away. According to the traditional interpretation in the official histories, in 617, Li Yuan was persuaded by Li Shimin to rebel against Sui rule. (Please see later section "Historial sources".) While Wen Daya (溫大雅)'s Da Tang chuangye qiju zhu (大唐創業起居注) recorded that the decision to revolt was attributed to Li Yuan himself. In 613, Li Yuan had already begun to have designs on the Sui throne but the timing was not right. When Sui Yangdi assigned Li Yuan to Taiyuan in 616, he was pleased and thought his assignment was Mandate of Heaven. In 617, Li Yuan said to Li Shimin: "The Sui Empire is about to collapse and the next family to rule this country would be us. The only reason I haven't begun rebellion is because your brothers are still in Hedong. "  Li Yuan sent secret messengers to Hedong to transfer his family to Jinyang. The whole family was led by Li Jiancheng and travelled long distance to the destination. The journey was full of danger and hardships, one of Li Jiancheng's younger brothers, Li Zhiyun died.
Even before Li Jiancheng, Li Yuanji, and Chai Shao (who, at the urging of Li Yuan's daughter, left Chang'an on his own while she went into hiding) arrived at Taiyuan, Li Yuan rebelled, declaring that he wanted to support Emperor Yang's grandson Yang You the Prince of Dai, then nominally in charge at Chang'an, as emperor, while honoring Emperor Yang as Taishang Huang (retired emperor).
Li Yuan made both Li Jiancheng and Li Shimin key generals, and in nine days, they captured Xihe Commandery (西河, roughly modern Lüliang, Shanxi), impressing their father. Subsequently, Li Yuan divided his forces into six armies, having Li Jiancheng and Li Shimin command three each. He also created Li Jiancheng the Duke of Longxi and Li Shimin the Duke of Dunhuang. Subsequently, Li Yuan advanced toward Chang'an, but when he got near to Hedong, his army could not advance due to torrential rains. With rumors running rampant that Liu Wuzhou and Eastern Tujue were about to attack Taiyuan, Li Yuan began ordering a retreat back to Taiyuan; it was only at Li Jiancheng's and Li Shimin's urging (that retreating back to Taiyuan would mean sure defeat) that Li Yuan changed his mind and stayed, and Li Jiancheng and Li Shimin then captured the fortress of Huoyi (霍邑, in modern Linfen, Shanxi), eventually convincing Li Yuan to bypass Hedong and directly advance toward Chang'an. After he crossed the Yellow River into Guanzhong (i.e., the Chang'an region), he sent Li Jiancheng with Liu Wenjing (劉文靜) east to guard Tong Pass and Yongfeng Storage (永豐倉) and to stop any potential Sui reinforcements from the eastern capital Luoyang. Once Li Yuan himself approached Chang'an, he summoned both Li Jiancheng and Li Shimin (whom he had sent north of the Wei River to seize territory) to Chang'an to join him in sieging Chang'an. In winter 617, Li Yuan captured Chang'an and declared Yang You emperor (as Emperor Gong). He had himself created the Prince of Tang, become the regent over Yang You.
In spring 618, Li Yuan sent Li Jiancheng and Li Shimin toward Luoyang, which was then under attack by the rebel leader Li Mi the Duke of Wei, ostensibly to help Sui forces there. The Sui forces at Luoyang rejected the overture, and Li Jiancheng and Li Shimin subsequently returned to Chang'an.
Tang imperial reunification
Later in spring 618, Emperor Yang, then at Jiangdu (江都, in modern Yangzhou, Jiangsu), was killed in a coup led by the general Yuwen Huaji. When the news arrived at Chang'an, Li Yuan had Yang You yield the throne to him, establishing Tang Dynasty as its Emperor Gaozu. Li Yuan created Li Jiancheng crown prince.
In 619,Li Yuan sent Li Jiancheng to attack the agrarian leader Zhu Shanhai (祝山海) the Duke of Huxiang, and Li Jiancheng defeated Zhu. Later that year, when Li Gui the Emperor of Liang was captured in a coup by his official An Xinggui (安興貴), who then submitted to Tang,Li Yuan sent Li Jiancheng to welcome An and to escort Li Gui to Chang'an, where Li Yuan executed him.
Meanwhile, Li Jiancheng was developing a reputation for leniency but favoring drinking and hunting. Li Yuan, worried that he was not paying sufficient attention to the important matters of state, had the key ministers Li Gang (李綱) and Zheng Shanguo (鄭善果) join Li Jiancheng's staff.
Campaigns against Tujue
On the 1st day of the 7th month of 620, Li Shimin was sent to fight Wang Shichong. In fall 620, believing in reports that Li Zhongwen (李仲文), who was then in charge at Taiyuan, was collaborating with Eastern Tujue, was planning to rebel, Li Yuan sent Li Jiancheng to Pufan (蒲反, i.e., Hedong) to guard against Li Zhongwen, while summoning Li Zhongwen back to the capital. Li Zhongwen complied and was subsequently executed.
In spring 621, when the Xiongnu chieftain Liu Xiancheng (劉仚成) harassed Tang's border territory, Li Yuan sent Li Jiancheng to attack Liu. When Li Jiancheng subsequently captured a number of the Xiongnu, he initially released their leaders, leading them to surrender in large numbers, and he then massacred them. Only Liu escaped and fled to Liang Shidu the Emperor of Liang. In 622, Li Jiancheng was one of the commanders that Li Yuan sent, along with Li Shimin, Li Zihe (李子和), and Duan Decao (段德操), to counter an Eastern Tujue incursion.
Rivalry with Li Shimin
Meanwhile, an intense rivalry had developed between Li Jiancheng and Li Shimin, who carried the title of Prince of Qin, as while Li Jiancheng had some contributions toward Tang's reunification of China, a number of the more major contenders, including Xue Rengao the Emperor of Qin, Wang Shichong the Emperor of Zheng, and Dou Jiande the Prince of Xia, were all defeated and/or captured by Li Shimin, causing him to possess the greater reputation among the army. Li Yuanji, who was also often relied on by Li Yuan as a general and had been created the Prince of Qi, supported Li Jiancheng in this rivalry, and often pushed Li Jiancheng toward a more hardline position against Li Shimin, wanting to be crown prince when Li Jiancheng would become emperor. Li Jiancheng and Li Yuanji had better relations with Li Yuan's favored young concubines than Li Shimin did (as their mother Duchess Dou had died before Tang's establishment), and those concubines helped rehabilitate Li Jiancheng's standing before Li Yuan, causing him to no longer consider making Li Shimin crown prince instead, as he considered at one point.
By winter 622, Liu Heita the Prince of Handong, previously a Xia general who rose against Tang after Li Yuan had executed Dou Jiande, posed the only remaining major threat against Tang rule even though he had been defeated by Li Shimin earlier in the year. At the suggestion of his staff members Wang Gui and Wei Zheng, who argued that Li Jiancheng needed some victories himself to establish his reputation, Li Jiancheng volunteered to command the army against Liu Heita. Li Yuan thus sent Li Jiancheng, assisted by Li Yuanji. Around the new year 623, with Liu's forced bogged down while attacking Tang's Wei Prefecture (魏州, in modern Handan, Hebei), Li Jiancheng and Li Yuanji engaged him at Guantao (館陶, in modern Handan as well), crushing him. Liu fled north toward Eastern Tujue, but was ambushed and captured by his own official Zhuge Dewei (諸葛德威), who delivered him to Li Jiancheng. Li Jiancheng executed Liu. China was by this point almost completely unified by Tang.
In 623, when Eastern Tujue made another incursion into Tang territory,Li Yuan again sent Li Jiancheng and Li Shimin to guard against the attack. Meanwhile, at one point, Li Yuanji tried to persuade Li Jiancheng to have Li Shimin assassinated when Li Shimin was visiting Li Yuanji's mansion, but Li Jiancheng, not having the heart to kill a brother, stopped Li Yuanji from doing so.
In 624, Li Jiancheng requisitioned a number of soldiers from the general Li Yi the Prince of Yan, to supplement his guard corps, against Li Yuan's regulations. When this was revealed to Li Yuan, Li Yuan rebuked Li Jiancheng and exiled his guard commander Keda Zhi (可達志). When, subsequently, Li Jiancheng nevertheless requested the commandant at Qing Prefecture (慶州, in modern Qingyang, Gansu), Yang Wen'gan (楊文幹), to conscript troops, presumably to guard against Li Shimin, the officers Erzhu Huan (爾朱煥) and Qiao Gongshan (橋公山) informed Li Yuan that Li Jiancheng was encouraging Yang to start a rebellion so that they could seize power together. Li Yuan, then at Renzhi Palace (仁智宮, in modern Tongchuan, Shaanxi), was incensed, and summoned Li Jiancheng, then at Chang'an, to Renzhi Palace. Li Jiancheng briefly flirted the idea of occupying Chang'an and not accepting the order, but eventually reported to Renzhi Palace to request forgiveness. Li Yuan put him under arrest. When Yang heard this, Yang rebelled, and Li Yuan, after promising Li Shimin that he would be made crown prince, sent Li Shimin to attack Yang. (Under Li Yuan's promise, Li Jiancheng would be removed as crown prince and created the Prince of Shu instead. He would then send Li Jiancheng to the modern Sichuan region.) Once Li Shimin left, however, Li Yuanji, Li Yuan's concubines, and the chancellor Feng Deyi, all spoke on Li Jiancheng's behalf, and Li Yuan changed his mind, released Li Jiancheng, and allowed him to return to Chang'an and remain as crown prince. Instead, Li Yuan only blamed the discord between his sons on Li Jiancheng's staff members Wang Gui and Wei Ting (韋挺), and Li Shimin's staff member Du Yan, exiling them. Yang was subsequently assassinated by his own subordinates.
Later that year, Li Yuan, troubled by repeated Eastern Tujue incursions, seriously considered burning Chang'an to the ground and moving the capital to Fancheng, a suggestion that Li Jiancheng, Li Yuanji, and the chancellor Pei Ji agreed with. Li Shimin opposed, however, and the plan was not carried out. Meanwhile, Li Shimin himself was sending his confidants to Luoyang to build up personal control of the army there.
The Poisoned Wine at Eastern Palace
According to "Zizhi Tongjian": On the 1st day of the 6th lunar month of 626, 3 days before Xuanwu Gate Incident, Li Jiancheng hosted a banquet for Li Shimin and Li Yuanji at his residence, Eastern Palace. Li Shimin got drunk and was carried back home after a night of drinking. Li Shimin reported through officials at his residence that he started vomiting a lot of a blood after his returning home. Li Yuan sent a royal decree to Li Jiancheng: "The prince of Qin (Li Shimin) has a low alcohol tolerance, therefore, he was forbidden to go out drinking at night." But Li Yuan did not mention anything about poison. Li Shimin apparently interpreted as an assassination attempt. Li Yuan considered sending Li Shimin to guard Luoyang to prevent further conflict. Li Jiancheng and Li Yuanji opposed the plan because they believed that this would only give Li Shimin an opportunity to build up his personal power. They expressed their concerns to Li Yuan's ministers who explained this to him that this plan could escalate a brother rivalry into a national conflict. Li Yuan, therefore, did not carry out the plan.
The date and the actual truth of this event were disputed. Zizhi Tongjian says it happened 3 days before Xuanwu Gate Incident. In Li Jiancheng's biography from "the Old book of Tang" and "the New book of Tang", it took place after Yang Wengan incident but several months before Xuanwu Gate Incident. However, in Fang Xuanling's biography from "the Old book of Tang", it happened before the founding of Tang, and wine was not mentioned. It is widely accepted by historians that it still remains a mystery whether or not someone poisoned Li Shimin at the Eastern Palace.d
By 626, Li Shimin was fearful that he would be killed by Li Jiancheng, and his staff members Fang Xuanling, Du Ruhui, and Zhangsun Wuji were repeatedly encouraging Li Shimin to attack Li Jiancheng and Li Yuanji first—while Wei Zheng was encouraging Li Jiancheng to attack Li Shimin first. Li Jiancheng persuaded Li Yuan to remove Fang and Du, as well as Li Shimin's trusted guard officers Yuchi Gong and Cheng Zhijie (程知節), from Li Shimin's staff. Zhangsun, who remained on Li Shimin's staff, continued to try to persuade Li Shimin to attack first.
In summer 626, Eastern Tujue was making another attack, and under Li Jiancheng's suggestion, Li Yuan, instead of sending Li Shimin to resist Eastern Tujue as he first was inclined, decided to send Li Yuanji instead. Li Yuanji was given command of much of the army previously under Li Shimin's control, further troubling Li Shimin, who believed that with the army in Li Yuanji's hands, he would be unable to resist an attack. Li Shimin had Yuchi summon Fang and Du back to his mansion secretly, and then on one night submitted an accusation to Li Yuan that Li Jiancheng and Li Yuanji were committing adultery with Li Yuan's concubines. Li Yuan, in response, issued summonses to Li Jiancheng and Li Yuanji for the next morning, convening the senior officials Pei Ji, Xiao Yu, and Chen Shuda to examine Li Shimin's accusations. As Li Jiancheng and Li Yuanji approached the central gate leading to Li Yuan's palace, Xuanwu Gate (玄武門), Li Shimin carried out the ambush he had set. He personally fired an arrow that killed Li Jiancheng. Subsequently, Yuchi killed Li Yuanji. Li Shimin's forces entered the palace and, under the intimidation of Li Shimin's forces, Li Yuan agreed to create Li Shimin crown prince, and two months later passed the throne to him (as Emperor Taizong). Li Jiancheng's five sons were all executed as well.
Li Jiancheng was initially posthumously reduced to commoner rank. After Emperor Taizong took the throne, he posthumously created Li Jiancheng the Prince of Xi and adopted his own son Li Fu (李福) into Li Jiancheng's line as Li Jiancheng's heir. He also buried Li Jiancheng with ceremonies due an imperial prince. In 642, he restored Li Jiancheng's crown prince title. However, for political considerations, he would never have Li Jiancheng fully rehabilitated, as the daughters of Li Jiancheng still remained the titles as daughters of a common prince, rather than a crown prince.
Da Tang chuangye qijuzhu
"Qijuzhu" is a type of imperial diary which records the emperor's daily activities. The purpose of Qijuzhu is to help govern the emperor's behavior by writing down every sayings and doings of a ruler, no matter good or bad. Therefore, the emperor must not read or ask about "Qijuzhu". It appeared as early as Han dynasty. In Tang dynasty, imperial diarist was in charge of "Qijuzhu". According to protocol, "Qijuzhu" should be edited and the original diary destroyed after the death of the emperor.
Da Tang chuangye qijuzhu 大唐创业起居注 can be translated as "Imperial diary of the foundation of the Great Tang". The author, Wen Daya (around 572 - 629 A.D.), was a Chinese historian during the late Sui and early Tang dynasty. He served as Li Yuan's records' staff and eyewitnessed the founding of Tang dynasty in 618. Da Tang chuangye qijuzhu was a three—chapter book with detailed narrative which was a firsthand account of the 357 days of insurrection. His work was finished before Li Shimin began influencing the official Emperor's records. Wen Daya was a supporter of Li Shimin during the later brother rivalry. Therefore there was no need for him to exaggerate Li Jiancheng's contribution to the Tang founding. Instead, he might exaggerate Li Shimin's role. As the only complete original court diary left from pre-Qing times, Da Tang chuangye qijuzhu is now generally considered a more reliable source on early Tang Dynasty.
Da Tang chuangye qijuzhu emphasizes that Li Yuan was the mastermind of the revolt against the Sui. Li Shimin, who was a teen at the time, only served as a secondary role in these events. Li Shimin made no greater contribution than Li Jiancheng to the founding of Tang empire. In the official histories, Li Jiancheng was described as an incompetent crown prince, alcoholic spendthrift and playboy spending most of his time hunting for fun. Li Yuan was also described as incompetent, a mediocre coward lack of ambition in the official histories. However, Wen Daya portrayed a different Li Jiancheng as a capable leader, generous, open-minded. He knew how to recruit talented people and did well in his early political career as a crown prince. Li Yuan, in Wen Daya's narrative, was a fearless leader with vision, courage and strategic planning.
In recent years historians have re-examined the evidence for events contained in the official histories ( the Old Book of Tang 旧唐书, the New Book of Tang 新唐书 and the Universal History Zizhi Tongjian 资治通鉴) and have concluded that important elements were probably fabricated during the reign of Li Shimin at his own insistence. On the basis of other material, most importantly a previously neglected early Tang dynasty source, Da-Tang chuangye qijuzhu, historians have been able to correct some of the bias and distortions of the official histories about the founding of Tang dynasty. Da Tang chuangye qijuzhu provides a clear example of how Li Shimin had history rewritten in favor of himself, who actually murdered his own brothers and deposed of his father. It also explained many self-contradictions found in the official histories. The truth that had intentionally been distorted and ignored by later official historians can be found in the Da Tang chuangye qijuzhu.

- a.^ The direct translation is "several (Chinese) Liters". 4 Chinese Liters during Sui-Tang era = 1 Liter today, or 2.1 pints today. So Li Shimin vomited no less than 1 liter of blood based on today's unit system after drinking. A human body has 5 liters of blood in total.

This obvious move could only make Li Yuan angry. It would also be difficult for Li Yuanji to carry out the plan since he was only a guest at a banquet in East Palace. Moreover, if it were found out, especially in this case the target did not die, it would break his political line with Li Jiancheng."
