![](static/wikilogo.png)
Taizong is typically considered to be one of the greatest emperors in China's history and henceforth, his reign became regarded as the exemplary model against which all future emperors were measured. His era, the "Reign of Zhenguan (貞觀之治 Zhēnguàn Zhī Zhì)" is considered a golden age in ancient Chinese history and was treated as required studying material for future crown princes. Taizong continued to develop imperial examination systems. He asked his officers to become loyal to the policies not people, in order to eliminate corruption. Under the Zhenguan era, Tang China flourished economically and militarily. For more than a century after his death, China enjoyed prosperity and peace brought about by the solidification of imperial protection over the Chinese regions. In territorial extent, it covered most of the territories previously held by the Han dynasty and parts of modern Korea, Vietnam, Xinjiang, and Central Asian regions. This era of consolidation and conquest laid the foundation for Xuanzong's reign, which is considered to be the height of the Tang dynasty.
In 630, Emperor Taizong sent his general Li Jing against the Eastern Turks, defeating and capturing their Jiali Khan Ashina Duobi and destroying their power. This made Tang the dominant power in East and Central Asia, and Emperor Taizong subsequently took the title of Tengeri Qaghan (天可汗 Tiān Kěhán|w=T'ien K'ehan, "Tenger Khan" or the God like Emperor). He also launched a series of campaigns against the oasis states of the Tarim Basin, and against the armies of their main ally, the Western Turks. During his reign, Tang armies annexed Karakhoja in 640, Karasahr in 644 and Kucha in 648. Eventually, the Tang defeated and annexed the Western Gokturk khaganate after Su Dingfang defeated Qaghan Ashina Helu in 657.
Unlike much of the nobility in his time, Emperor Taizong was a frank rationalist and scholar of logic and scientific reason, openly scorning superstitions and claims of signs from the heavens. He also modified important rites in order to ease the burden of agricultural labour. The modern Chinese historian Bo Yang opined that Emperor Taizong achieved greatness by enduring criticism which others would find difficult to accept whilst trying hard not to abuse his absolute power (using Emperor Yang of Sui as a negative example), as well as through his employment of capable chancellors such as Fang Xuanling, Du Ruhui and Wei Zheng. Emperor Taizong's wife Empress Zhangsun also proved to be a capable assistant.

Early life
Lǐ Shìmín was born in 598 at Wugong, in modern Xianyang, Shaanxi). His father Li Yuan, the Duke of Tang, was a general of the Sui Dynasty, and a nephew, by marriage, to Sui's founding emperor Emperor Wen. Li Shimin's grandmother Duchess Dugu was a sister of Empress Dugu, both of whom were daughters of Dugu Xin, a major Xianbei general during Sui's predecessor dynasty Northern Zhou. Li Shimin's mother, Li Yuan's wife Duchess Dou, was a daughter of Dou Yi, the Duke of Shenwu, and his wife, Northern Zhou's Princess Xiangyang. Duchess Dou bore Li Yuan four sons—an older brother to Li Shimin, Li Jiancheng, and two younger brothers, Li Yuanba (李元霸), who would die in 614, and Li Yuanji – and at least one daughter (the later Princess Pingyang). Li Yuan named Li Shimin "Shimin" as a shortened form of the phrase "save the earth and pacify the people" (濟世安民 jìshì ānmín). Li Shimin apparently showed talent early in his life, and in 613, the official Gao Shilian, impressed with him, gave him a niece (the later Empress Zhangsun) in marriage as his wife; he was 14 and she was 12. In 615, when Emperor Wen's son and successor Emperor Yang was ambushed by Eastern Turkish (Dongtujue) forces under Shibi Khan at Yanmen Commandery (present-day Daixian in Shanxi), a general call was made for men to join the army to help rescue the emperor. Li Shimin answered that call and served under the general Yun Dingxing, apparently doing so with distinction. In 616, when Li Yuan was put in charge of the important city of Taiyuan, he brought Li Shimin with him to Taiyuan, while leaving at least three other sons—Li Jiancheng, Li Yuanji, and Li Zhiyun (, by Li Yuan's concubine Lady Wan)—at the ancestral home Hedong (, in modern Yuncheng, Shanxi).
Participation in the rebellion against Sui rule
Emperor Yang was soon dissatisfied with Li Yuan and Wang Rengong (王仁恭), the governor of Mayi Commandery (, roughly modern Shuozhou, Shanxi), over their inability to stop Eastern Turkish incursions and the growing strength of agrarian rebels, particularly the Eastern Turkish-supported Liu Wuzhou, who soon rose against Wang, killed him, and captured Emperor Yang's secondary palace near Taiyuan. Li Yuan also became fearful of a prophecy that the next emperor would be named Li — Emperor Yang had previously killed another official, Li Hun, and Li Hun's clan over his fear that Li Hun's nephew, Li Min (李敏, would seize the throne.
Fearful for his life, Li Yuan considered rebellion. However, he did not know that Li Shimin had also been secretly discussing plans for rebellion with Li Yuan's associates Pei Ji and Liu Wenjing. Once Li Shimin's plans matured, he had Pei inform Li Yuan of them—and also had Pei warn Li Yuan that if it were revealed that Li Yuan had had sexual relations with some of Emperor Yang's ladies in waiting at the secondary Jinyang Palace (, which Pei was in charge with and had allowed Li Yuan to do so), all of them would be slaughtered. Li Yuan agreed to rebel, and after secretly summoning Li Jiancheng and Li Yuanji from Hedong and his son-in-law Chai Shao (柴紹) from the capital Chang'an, he declared a rebellion, claiming to want to support Emperor Yang's grandson Yang You the Prince of Dai, nominally in charge at Chang'an with Emperor Yang at Jiangdu (江都, in modern Yangzhou, Jiangsu), as emperor. He made both Li Jiancheng and Li Shimin major generals and advanced southwest, toward Chang'an. He gave Li Shimin the title of Duke of Dunhuang. After defeating local Sui forces loyal to Emperor Yang, he defeated a Sui army of 30,000 men under the command of a veteran general of the wars in Korea outside of modern-day Beijing.
However, when Li Yuan arrived near Hedong, his army was bogged down by the weather. With food running out, there were rumors that the Eastern Turks and Liu Wuzhou would attack Taiyuan. Li Yuan initially ordered retreat, but at the earnest opposition by Li Jiancheng and Li Shimin, continued to advance. After defeating Sui forces at Huoyi (霍邑, also in modern Yuncheng), he decided to leave a small contingent to watch over Hedong while advancing across the Yellow River into Guanzhong (i.e., the Chang'an region). Once he did, he headed for Chang'an himself, while sending Li Jiancheng to capture the territory around the Tong Pass region to prevent Sui forces at Luoyang from reinforcing Chang'an and Li Shimin north of the Wei River to capture territory there. Meanwhile, Li Shimin's sister (Chai's wife) had also risen in rebellion in support of him, and she was able to gather a sizeable army and capture some cities. She joined forces with Li Shimin and her husband Chai Shao. Soon, Li Yuan reconsolidated his forces and put Chang'an under siege. In winter 617, after defeating a large Sui army, he captured Chang'an from imperial forces and declared Yang You emperor (as Emperor Gong). He had himself made regent (with the title of grand chancellor) and created the Prince of Tang. (Meanwhile, most of the Sui territories and armies did not recognize Emperor Gong as emperor and continued to recognize Emperor Yang as emperor and not as retired emperor.) He created Li Shimin the Duke of Qin.
Li Yuan's control of the Chang'an region became almost immediately contested by the rebel ruler Xue Ju the Emperor of Qin, who sent his son Xue Rengao toward Chang'an. Li Yuan sent Li Shimin to resist Xue Rengao, and Li Shimin defeated Xue Rengao at Fufeng, in modern Baoji, Shaanxi), temporarily causing Xue Ju to toy with the idea of surrendering to Li Yuan, although Xue was subsequently dissuaded by his strategist Hao Yuan (郝瑗) from doing so.
In spring 618, with Sui's eastern capital Luoyang (where the officials in charge did not recognize Li Yuan's authorities) under attack by the rebel ruler Li Mi the Duke of Wei, Li Yuan sent Li Jiancheng and Li Shimin to Luoyang, ostensibly to aid the Sui forces at Luoyang but instead intending to test whether Luoyang might submit to him. The officials at Luoyang rebuffed his attempt at rapprochement, and Li Jiancheng and Li Shimin, not wanting to fight either them or Li Mi for control of Luoyang at this stage, withdrew. Li Yuan subsequently changed Li Shimin's title to Duke of Zhao.
In summer 618, when news arrived at Chang'an that Emperor Yang had been killed at Jiangdu in a coup led by the general Yuwen Huaji, Li Yuan had Emperor Gong yield the throne to him, establishing Tang Dynasty as its Emperor Gaozu. He created Li Jiancheng crown prince but created Li Shimin the Prince of Qin, also making him Shangshu Ling, the head of the executive bureau of the government (尚書省 Shàngshū Shěng) and a post considered one for a chancellor, while continuing to have Li Shimin serve as a major general as well.
During Emperor Gaozus reign
Campaign to reunify the empire
The first thing that Li Shimin had to deal with was another incursion by Xue Ju, as Xue attacked Jing Prefecture (, roughly modern Pingliang, Gansu) and Emperor Gaozu sent Li Shimin to resist Xue. Li Shimin established his defenses and refused to engage Xue to try to wear Xue Ju out, but at that time, he was afflicted with malaria, and he let his assistants Liu Wenjing and Yin Kaishan take command, ordering them not to engage Xue Ju. Liu and Yin, however, did not take Xue Ju seriously, and Xue Ju ambushed them at Qianshui Plain (, in modern Xianyang), crushing Tang forces and inflicting 50%–60% casualties. Li Shimin was forced to withdraw back to Chang'an, and Liu and Yin were removed from their posts. (This would be Li Shimin's only defeat recorded in historical records until the Goguryeo campaign of 645.) Xue Ju, in light of his victory, was ready to launch an assault on Chang'an itself, under Hao Yuan's advice, but suddenly died of an illness in fall 618 and was succeeded by Xue Rengao. Emperor Gaozu then sent Li Shimin against Xue Rengao. Three months after Xue Rengao took the throne, Li Shimin engaged him, and after a fierce battle between Li Shimin and Xue Rengao's major general Zong Luohou, Li Shimin crushed Zong's forces, and then attacked Xue Rengao. Xue Rengao was forced to withdraw into the city of Gaozhi (高墌, in modern Xianyang as well), and once he did, his soldiers began surrendering to Li Shimin en masse. Xue Rengao was himself forced to surrender. Li Shimin had him delivered to Chang'an, where he was executed. Around new year 619, Emperor Gaozu made Li Shimin Taiwei (太尉, one of the Three Excellencies) and put him in charge of Tang operations east of the Tong Pass.
In spring 619, Liu Wuzhou launched a major offensive against Tang. He captured Taiyuan in summer 619, forcing Li Yuanji, who had been in charge there, to flee, and then continued his offensive south. Emperor Gaozu sent Pei Ji against him, but by winter 619, Liu had crushed Pei's forces and taken over nearly all of modern Shanxi. Emperor Gaozu, shocked at the development, considered abandoning the region altogether. Li Shimin opposed doing so and offered to lead the army against Liu. Emperor Gaozu agreed and commissioned him with an army. He crossed the Yellow River and approached Liu's major general Song Jingang but did not engage him, choosing to try to wear Song out, only having his subordinates Yin Kaishan and Qin Shubao engage the other Dingyang generals Yuchi Jingde and Xun Xiang in relatively low-level engagements. Eventually, in spring 620, when Liu and Song ran out of food supplies, they retreated, and Li Shimin gave chase, dealing Song a major defeat. Yuchi and Xun surrendered, and after Li Shimin chased further, both Liu and Song fled to the Eastern Turks. All of Dingyang territory fell into Tang hands.
In summer 620, Emperor Gaozu again commissioned Li Shimin against a major enemy—the former Sui general Wang Shichong, who had Sui's last emperor, Emperor Yang's grandson Yang Tong, yield the throne to him in 619, establishing a new state of Zheng as its emperor. When Li Shimin arrived at the Zheng capital Luoyang, Wang offered peace, but Li Shimin rebuffed him and put Luoyang under siege. Meanwhile, his subordinates took Zheng cities one by one. By winter 620, most of Zheng territory, other than Luoyang and Xiangyang, defended by Wang Shichong's nephew Wang Honglie (王弘烈), had submitted to Tang. Wang sought aid Dou Jiande the Prince of Xia, who controlled most of modern Hebei. Dou, reasoning that if Tang were able to destroy Zheng, his own Xia state would be next, agreed. He sent his official Li Dashi to try to persuade Li Shimin to withdraw, but Li Shimin detained Li Dashi and gave no response. Meanwhile, during the campaign, Li Shimin chose some 1,000 elite soldiers, clad in black uniform and black armor, commanded by himself, to serve as advance troops, with Qin Shubao, Yuchi Jingde, Cheng Zhijie, and Zhai Zhangsun as his assistants.
By spring 621, Luoyang was in desperate situation, and Xia forces had not yet arrived, but Tang troops had also suffered serious casualties, as Luoyang's defenses, aided by powerful bows and catapults, were holding. Emperor Gaozu, hearing that Dou had decided to come to Wang's aid, ordered Li Shimin to withdraw, but Li Shimin sent his secretary Feng Deyi to Chang'an to explain to Emperor Gaozu that if he did withdraw, Wang would recover and again be a major threat in the future. Emperor Gaozu agreed and allowed Li Shimin to continue to siege Luoyang. When Xia forward troops arrived first, Li Shimin surprised and defeated them, and then sent Dou a letter suggesting that he withdraw. Dou would not do so, and, against the advice of his wife Empress Cao and secretary general Ling Jing (凌敬) that he should instead attack Tang's prefectures in modern southern Shanxi, he marched toward Luoyang. Anticipating Dou's maneuver, Li Shimin left a small detachment, commanded by Li Yuanji, at Luoyang, while marching east himself, taking up position at the strategic Hulao Pass. When the armies engaged at Hulao, Li Shimin defeated Dou and captured him. He took Dou back to Luoyang and displayed him to Wang Shichong. Wang, in fear, considered abandoning Luoyang and fleeing south to Xiangyang, but as his generals pointed out that his only hope was Dou, he surrendered. Xia forces, after initially fleeing back to their capital Mingzhou (now Guangfu, Hebei), also surrendered. Zheng and Xia territory were Tang's. Li Shimin returned to Chang'an in a grand victory procession and, to reward Li Shimin, Emperor Gaozu awarded both him and Li Yuanji three mints so that they could mint money of their own. He also bestowed on Li Shimin the special title of "Grand General of Heavenly Strategies" (天策上將 tiāncè shàngjiàng). Meanwhile, Li Shimin's staff, already full of generals and strategists, were supplemented with a number of literary men.
The former Xia territory did not remain in Tang hands for long. In the winter of 621, the Xia general Liu Heita rose against Tang rule, claiming to be avenging Dou, whom Emperor Gaozu had executed against Li Shimin's wishes after he had been brought back to Chang'an. Liu was allied with Xu Yuanlang, a former agrarian rebel general who was nominally under Wang Shichong and who had submitted to Tang after Wang's defeat. Liu dealt successive defeats to Emperor Gaozu's cousin Li Shentong (李神通), the Prince of Huai'an; Li Xiaochang (李孝常), the Prince of Yi'an; and Li Shiji. By the end, he had recovered almost all of the former Xia territory, established his capital at Mingzhou, and proclaimed himself the Prince of Handong. Emperor Gaozu finally sent Li Shimin and Li Yuanji against him in 622 and, after some indecisive battles, Li Shimin defeated him by first erecting a dam across the Ming River and then destroying it, with the resultant flood destroying the rebel army. Liu fled to the Eastern Turks, while Li Shimin then headed east and defeated Xu. After leaving Li Shiji, Li Shentong, and Ren Gui to continue attacking Xu, Li Shimin returned to Chang'an.
Struggle against Li Jiancheng and Li Yuanji
By this point, Li Shimin and his older brother Li Jiancheng, who was created crown prince in 618, reportedly after Emperor Gaozu first offered the position to Li Shimin due to his contributions, were locked in an intense rivalry, as Li Shimin's accomplishments caused people to speculate that he would displace Li Jiancheng as crown prince, and Li Jiancheng, while an accomplished general himself, was overshadowed by his younger brother. The court became divided into a faction favoring the Crown Prince and a faction favoring the Prince of Qin. The rivalry was particularly causing problems within the capital, as the commands of the Crown Prince, the Prince of Qin, and the Prince of Qi (i.e., Li Yuanji) were said to have the same force as the emperor's edicts, and the officials had to carry conflicting orders out by acting on the ones that arrived first. Li Shimin's staff was full of talented men, but Li Jiancheng was supported by Li Yuanji, as well as Emperor Gaozu's concubines, who had better relationships with Li Jiancheng and Li Yuanji than they did with Li Shimin.
Late in 622, when Liu Heita returned east after receiving aid from the Eastern Turks, defeating and killing Li Shimin's cousin Li Daoxuan (李道玄), the Prince of Huaiyang, he again regained most of former Xia territory. Li Jiancheng's staff members Wang Gui and Wei Zheng suggested that Li Jiancheng needed to enhance his own reputation in battle, and so Li Jiancheng volunteered for the mission. Emperor Gaozu thus sent Li Jiancheng, assisted by Li Yuanji, to attack Liu. Li Jiancheng defeated Liu around the new year of 623, and Liu was subsequently betrayed by his own official Zhuge Dewei and delivered to Li Jiancheng. Li Jiancheng executed Liu in his former capital and returned to Chang'an in triumph. China was, by this point, roughly united under Tang rule.
For the next few years, the rivalry intensified, although during the meantime both Li Jiancheng and Li Shimin served as generals when the Eastern Göktürks made incursions. In 623, when the general Fu Gongshi rebelled at Danyang (, in modern Nanjing, Jiangsu), Emperor Gaozu briefly commissioned Li Shimin to attack Fu, but soon cancelled the order and sent Li Shimin's cousin Li Xiaogong the Prince of Zhao Commandery instead.
In 624, when Li Jiancheng was found to have, against regulations, tried to add soldiers to his guard corps, Emperor Gaozu was so angry that he put Li Jiancheng under arrest. In fear, Li Jiancheng's guard commander Yang Wen'gan rebelled. Emperor Gaozu sent Li Shimin against Yang, offering to make him crown prince after he returned. After Li Shimin left, however, Feng Deyi (now a chancellor), Li Yuanji, and the concubines all spoke on Li Jiancheng's behalf, and after Li Shimin returned, Emperor Gaozu did not depose Li Jiancheng, but instead blamed the discord between him and Li Shimin on Li Jiancheng's staff members Wang Gui and Wei Ting and Li Shimin's staff member Du Yan, exiling them to Xi Prefecture (, roughly modern Liangshan Yi Autonomous Prefecture, Sichuan).
Later that year, Emperor Gaozu, troubled by repeated Göktürk incursions, seriously considered burning Chang'an to the ground and moving the capital to Fancheng, a suggestion that Li Jiancheng, Li Yuanji, and 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. After an incident in which Li Shimin suffered a severe case of food poisoning after feasting at Li Jiancheng's palace—an event that both Emperor Gaozu and Li Shimin apparently interpreted as an assassination attempt—Emperor Gaozu considered sending Li Shimin to guard Luoyang to prevent further conflict, but Li Jiancheng and Li Yuanji, after consulting each other, believed that this would only give Li Shimin an opportunity to build up his personal power there, and therefore opposed it. Emperor Gaozu therefore did not carry out the plan. Meanwhile, the rivalry continued. Traditional historical accounts also indicated that at one point, when Li Shimin visited Li Yuanji's mansion, Li Yuanji wanted to assassinate Li Shimin, but Li Jiancheng, who could not resolve to kill a brother, stopped the plot. There was yet another incident in which Li Jiancheng, knowing that a horse threw its rider easily, had Li Shimin ride it, causing Li Shimin to fall off from it several times.
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 Emperor Gaozu to remove Fang and Du, as well as Li Shimin's trusted guard generals Yuchi Jingde and Cheng Zhijie, from Li Shimin's staff. Zhangsun Wuji, who remained on Li Shimin's staff, continued to try to persuade Li Shimin to attack first.
In summer 626, the Göktürks were making another attack, and under Li Jiancheng's suggestion, Emperor Gaozu, instead of sending Li Shimin to resist the Göktürks 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 Emperor Gaozu that Li Jiancheng and Li Yuanji were committing adultery with Emperor Gaozu's concubines. Emperor Gaozu, 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 Emperor Gaozu's palace, Xuanwu Gate, Li Shimin carried out the ambush he had set. He personally fired an arrow that killed Li Jiancheng. Subsequently, Yuchi Jingde killed Li Yuanji. Li Shimin's forces entered the palace and, under the intimidation of Li Shimin's forces, Emperor Gaozu agreed to create Li Shimin crown prince. Li Jiancheng's and Li Yuanji's sons were killed, and Li Shimin took Li Yuanji's wife Princess Yang as a concubine. Two months later, with Li Shimin firmly in control of power, Emperor Gaozu yielded the throne to him (as Emperor Taizong).
As emperor
Early reign (626–633)
One of the first actions that Emperor Taizong carried out as emperor was releasing a number of ladies in waiting from the palace and returning them to their homes, so that they could be married. He made his wife Princess Zhangsun the empress, and their oldest son Li Chengqian the crown prince.
Emperor Taizong also immediately faced a crisis, as the Eastern Turkish leader Jiali Khan Ashina Duobi, along with his nephew the subordinate Tuli Khan Ashina Shibobi (阿史那什鉢苾), launched a major incursion toward Chang'an, and just 19 days after Emperor Taizong took the throne, the two khans were just across the Wei River from Chang'an. Emperor Taizong, accompanied by Gao Shilian and Fang Xuanling, was forced to meet Ashina Duobi across the river and personally negotiate peace terms, including tributes to Eastern Turks, before Ashina Duobi withdrew.
Late in 626, Emperor Taizong ranked the contributors to Tang rule and granted them titles and fiefs, naming among the first rank of contributors Zhangsun Wuji, Fang Xuanling, Du Ruhui, Yuchi Jingde, and Hou Junji. When Li Shentong, as his distant uncle, objected to being ranked under Fang and Du, Emperor Taizong personally explained how Fang and Du's strategies allowed him to be successful, and this managed to get the other objectors to quiet down, as Emperor Taizong was even willing to rank low such an honored individual as Li Shentong. Emperor Taizong also buried Li Jiancheng and Li Yuanji with honors due imperial princes and had their staff members attend the funeral processions. Meanwhile, he appeared to begin to reshuffle government further—which he had already begun after being created crown prince—by dismissing his father's trusted advisors Xiao Yu and Chen Shuda, making his own trusted advisors chancellors. (Xiao, however, was soon restored to being chancellor, although his career during Emperor Taizong's reign would see repeated dismissals and repeated restorations.) However, he also began to greatly pay attention to the officials' submissions and their criticism of imperial governance, making changes where he saw needed. He also particularly began to trust Wei Zheng, accepting much advice from Wei as far as his personal conduct was concerned. He was also willing to demote his own trusted advisors, as he demoted Gao Shilian after finding that Gao had held back submissions from his deputy Wang Gui. Viewing Sui's Emperor Yang as a negative example, he frequently solicited criticism, rewarding those officials willing to offer them, particularly Wei and Wang Gui. His openness to opposing ideas was also evident in his attempt to reconcile traditional Taoist religion and Buddhism, as demonstrated in his Emperor's Preface to the Sacred Teachings.
Li Yis Rebellion
Also in 627, the general Li Yi the Prince of Yan—a late-Sui warlord who later submitted to Tang, who associated with Li Jiancheng—fearing that Emperor Taizong would eventually take action against him, rebelled at Bin Prefecture (豳州, in modern Xianyang), but was quickly crushed by the official Yang Ji and killed in flight. Later that year, when Emperor Gaozu's cousin Li Youliang (李幼良) the Prince of Changle, the commandant at Liang Prefecture (, roughly modern Wuwei, Gansu), was accused of allowing his staff to oppress the people and to trade with Qiang and Xiongnu tribesmen, Emperor Taizong sent the chancellor Yuwen Shiji (Yuwen Huaji's brother) to investigate, and in fear, Li Youliang's staff members plotted to hold him hostage and rebel. When this was discovered, Emperor Taizong forced Li Youliang to commit suicide. Late in the year, Wang Junkuo (王君廓), the commandant at You Prefecture (幽州, roughly modern Beijing), also rebelled, but was defeated quickly and killed in flight. However, although there were also reports that Feng Ang, a warlord in the Lingnan region, was rebelling, Emperor Taizong, at Wei's suggestion, sent messengers to comfort Feng, and Feng submitted.
Also in 627, Emperor Taizong, seeing that there were too many prefectures and counties, consolidated and merged many of them, and further created another level of local political organization above prefectures—the circuit (道 dào) – dividing his state into 10 circuits.
Campaign against the Eastern Turks
In 628, with Ashina Duobi and Ashina Shibobi having a falling out, Ashina Shibobi submitted to Emperor Taizong, as did the chieftains of Khitan tribes, who had previously submitted to the Eastern Turks. With their khaganate in turmoil, Ashina Duobi was no longer able to protect the last late-Sui rebel ruler who alone remained standing against Tang pressure – Liang Shidu the Emperor of Liang, and in summer 628, with the Tang generals Chai Shao and Xue Wanjun sieging the Liang capital Shuofang (in modern Yulin, Shaanxi), Liang Shidu's cousin Liang Luoren (梁洛仁) killed Liang Shidu and surrendered, finally uniting China. With the Eastern Turkish state weakened, their vassal Xueyantuo also broke away and formed its own khanate, and Emperor Taizong entered into an alliance with Xueyantuo's leader Yinan, creating Yinan the Zhenzhupiqie Khan (or Zhenzhu Khan in short).
In late 629, believing the time ripe for a major attack on the Eastern Turks, Emperor Taizong commissioned the general Li Jing with overall command of a multi-pronged army, assisted by the generals Li Shiji, Li Daozong, Chai Shao, Xue Wanche (, Xue Wanjun's brother) and Su Dingfang, attacking the Eastern Turks at multiple points. The army was successful in its attacks, forcing Ashina Duobi to flee, and by late spring 630, Ashina Duobi had been captured, and Eastern-Turkish chieftains all submitted to Tang. Emperor Taizong spared Ashina Duobi but detained him at Chang'an, and he considered what to do with the Eastern Turks.
The main opposing views were from the chancellors Wen Yanbo (who advocated leaving the Turks within China's borders to serve as a defense perimeter) and Wei (who advocated leaving them outside the borders). Emperor Taizong accepted Wen's suggestion and established a number of prefectures to accommodate the Turks, leaving them governed by their chieftains without creating a new khan to govern them.
In 631, Emperor Taizong established a feudal scheme, where the contributors to his reign were given, in addition to their current posts, additional posts as prefectural governors, to be passed on to their descendants. Soon, however, receiving much opposition to the plan, the strongest of which came from Zhangsun Wuji, Emperor Taizong cancelled the scheme.
After the conquest of the Eastern Turkic Khaganate, Emperor Taizong's officials repeatedly requested that he carry out sacrifices to heaven and earth at Mount Tai, and Emperor Taizong, while at times tempted by the proposal, was repeatedly dissuaded from doing so by Wei, who pointed out the expenses and the labors that would be imposed on the people as a result, and also that this would open China's borders to attack.
Middle reign (634–641)
In 634, Emperor Taizong sent 13 high level officials, including Li Jing and Xiao Yu, to examine the circuits 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. (Li Jing initially recommended Wei Zheng, but Emperor Taizong declined sending Wei, stating that Wei needed to stay to point out his faults and that he could not afford to have Wei away even for a single day.)
Campaign against Tuyuhun
Around this time, Tang was having increasing conflicts with Tuyuhun, whose Busabo Khan Murong Fuyun, under instigation by his strategist the Prince of Tianzhu, had been repeatedly attacking Tang prefectures on the borders. At one point, Murong Fuyun sought to have a Tang princess marry his son the Prince of Zun, but the marriage negotiations broke down over Emperor Taizong's insistence that the Prince of Zun come to Chang'an for the wedding. In summer 634, Emperor Taizong had the generals Duan Zhixuan and Fan Xing lead forces against Tuyuhun, but with Tuyuhun's forces highly mobile and avoiding direct confrontation, Duan, while not defeated, could not make major gains. Once Duan withdrew, Tuyuhun resumed hostilities. In winter 634, with the Tibetan king Songtsän Gampo making overtures to marry a Tang princess as well, Emperor Taizong sent the emissary Feng Dexia to Tibet with an eye toward an alliance against Tuyuhun. In winter 634, he commissioned Li Jing, assisted by the other generals Hou Junji, Xue Wanjun, Xue Wanche, Qibi Heli, Li Daozong, Li Daliang, Li Daoyan, and Gao Zengsheng (高甑生), to attack Tuyuhun. In 635, Li Jing's forces crushed Tuyuhun forces. Murong Fuyun was killed by his own subordinates, and his son Murong Shun killed the Prince of Tianzhu and surrendered. Emperor Taizong created Murong Shun the new khan, although Murong Shun was soon assassinated. Emperor Taizong then created Murong Shun's son Murong Nuohebo as the new khan.
Also in 635, Emperor Gaozu died, and Emperor Taizong, observing a mourning period, briefly had Li Chengqian serve as regent, and after he resumed his authorities less than two months later, he still authorized Li Chengqian to thereafter rule on minor matters.
In spring 636, Emperor Taizong commissioned his brothers and sons as commandants and changed their titles in accordance with the commands that they received, sending them to their posts—with the exception of his son Li Tai the Prince of Wei, who by this point was beginning to be highly favored by him. He further allowed Li Tai to engage literary men to serve as his assistants, as Li Tai favored literature. From this point on, Li Tai would be so favored that there began to be talks that Emperor Taizong might let him displace Li Chengqian, whose favors began to wane.
In fall 636, Empress Zhangsun died. Emperor Taizong mourned her bitterly and personally wrote the text of her monument.
In summer 637, Emperor Taizong recreated the feudal scheme that he had considered and abandoned in 631, creating 35 hereditary prefect posts. (By 639, however, the system was again abandoned after much opposition.)
Treatment of Noble Clan
Sometime before 638, Emperor Taizong, disgusted with the traditional noble clans of Cui, Lu, Li, and Zheng and believing that they were abusing their highly honored names, commissioned Gao Shilian, Wei Ting, Linghu Defen, and Cen Wenben to compile a work later to be known as the Records of Clans (氏族志), with the intent of dividing the clans into nine classes based on their past contributions, good deeds, and ill deeds. In an initial draft that Gao submitted, he nevertheless ranked the branch of the Cui clan that the official Cui Min'gan belonged to as the highest, a decision that Emperor Taizong rebuked, as he pointed out that Gao was merely again looking at tradition and not the recent contributions. He therefore personally intervened in revising the work, reducing Cui's clan to the third class.
Tibetan attack on Songzhou
In fall 638, Tibet's Songtsän Gampo, displeased that Emperor Taizong had declined to give him a Tang princess in marriage and believing that Murong Nuohebo had persuaded Emperor Taizong to decline the marriage proposal, launched a major attack with forces of 200,000 on Tuyuhun and then on several Tang prefectures, putting Song Prefecture (松州, roughly modern Ngawa Tibetan and Qiang Autonomous Prefecture, Sichuan) under siege. Emperor Taizong commissioned Hou Junji, assisted by Zhishi Sili, Niu Jinda, and Liu Jian, of a total of force of 50,000 to counterattack, and Niu, who commanded the forward forces, defeated Tibetan forces at Song Prefecture. Songsän Gampo withdrew and sued for peace, but still sought to marry a Tang princess. Emperor Taizong agreed this time.
Also in 638, believing that Xueyantuo was growing increasingly strong and difficult to control, Emperor Taizong granted Yinan's sons Bazhuo and Jialibi both lesser khan titles, to try to create dissensions between them.
In summer 639, Ashina Jiesheshuai, the younger brother of Ashina Shibobi, whom Emperor Taizong did not favor and gave little recognition to, formed a conspiracy with Ashina Shibobi's son Ashina Hexiangu to assassinate Emperor Taizong. They had planned to wait for Li Zhi the Prince of Jin to depart from the palace in the morning and use that opportunity to attack the palace. On the day they planned, however, Li Zhi did not leave the palace, and Ashina Jiesheshuai attacked anyway but was quickly defeated, captured, and executed. After this incident, however, the officials began advocating sending the Turks away from the heart of the state. In fall 639, Emperor Taizong created a Turkish prince who had served him faithfully, Li Simo (né Ashina Simo) as the khan of a newly recreated Eastern Turkish state (as Qilibi Khan), giving him all of the Turks and Xiongnu who had surrendered as his subordinates, to be settled north of the Great Wall and the Yellow River. However, the Turks were fearful of Xueyantuo and initially refused to head to their new location. Emperor Taizong issued an edict to Yinan that he and Li Simo keep their peace and not attack each other, and after receiving from Yinan the assurance that he would not attack, the Turks advanced to the new location.
Campaign against Western Turks
Taizong began a series of campaigns against the Western Turks (Xitujue) and their allies, the oasis states of the Tarim Basin, around 640. These hostilities between the Western Turks and Tang would continue until the defeat and conquest of the Western Turks in 657 under Taizong's successor, Gaozong. The kingdoms of Shule and Khotan surrendered to the Chinese in 632, as did the kingdom of Yarkand in 635. Qu Wentai (麴文泰), the king of Gaochang, who had previously been submissive to Tang, had become increasingly hostile to Tang, allying with the Western Turks. In 640, Emperor Taizong commissioned Hou Junji, assisted by Xue Wanjun, to launch a major attack on Gaochang. As they approached Gaochang, Qu Wentai died in fear and was succeeded by his son Qu Zhisheng (麴智盛). Qu Zhisheng offered to submit, but Hou demanded a surrender, which Qu Zhisheng refused. However, Hou put Gaochang under siege, and with aid from the Western Turks not arriving, Qu Zhisheng surrendered. Wei Zheng suggested that Emperor Taizong allow Qu Zhisheng to remain king, pointing out that the monetary and human costs would be high to keep a permanent garrison at Gaochang, but Emperor Taizong disagreed, and he converted Gaochang into two prefectures and annexed it into his state.
In winter 640, Songsän Gampo sent his prime minister Gar Tongtsen Yülsung ("Lu Dongzan" in Chinese) as an emissary to Tang, offering tributes and again requesting marriage. Emperor Taizong created a daughter of a clansman as the Princess Wencheng, and in 641 sent Li Daozong to accompany Princess Wencheng to Tibet to preside over the wedding.
In winter 641, believing that Emperor Taizong was about to carry out sacrifices to heaven and earth at Mount Tai and would be unable to aid the Eastern Turks, Yinan launched a major attack on them, commanded by his son Dadu (大度). Li Simo was forced to retreat inside the Great Wall. Emperor Taizong commissioned Li Shiji, assisted by Zhang Jian, Li Daliang, Zhang Shigui, and Li Xiyu, to attack Xueyantuo. Li Shiji soon defeated Dadu at Nuozhen River (, flowing through modern Baotou, Inner Mongolia), and Dadu fled.
Late reign (642–649)
By 642, it was clear that Li Tai had ambitions on replacing his brother Li Chengqian, and the governmental officials began to be divided into pro-Li Chengqian and pro-Li Tai factions. After urging by Wei Zheng and Chu Suiliang to take actions that would clarify that Li Chengqian's position was secure, Emperor Taizong attempted to do so by making repeated statements to that effect, but his continued favoring of Li Tai led to continued speculation among officials.
Also by 642, Xueyantuo had posed a sufficiently serious threat (albeit still formally submissive) that Emperor Taizong saw two alternatives—destroying it by force or forming into a heqin relationship by marrying one of his daughters to Yinan. This particularly became an issue after the Tang general Qibi Heli (契苾何力), the chieftain of the Qibi Tribe, was kidnapped by his own subordinates and taken to Xueyantuo. In order to ransom Qibi, Emperor Taizong made a promise to eventually give his daughter Princess Xinxing to Yinan in marriage, and Yinan released Qibi.
In the winter 642, an event took place in Goguryeo that would eventually precipitate wars between Tang and Goguryeo. According to Chinese accounts King Yeongnyu, the king of Goguryeo, was apprehensive about his general Yeon Gaesomun and was plotting with his other officials to kill Yeon. When Yeon received the news, he started a coup and killed the king and the high level officials. He declared King Yeongnyu's nephew Go Jang (King Bojang) king, while taking power himself with the title of Dae Mangniji (, Generalissimo). When Emperor Taizong received the news, there were suggestions that an attack be launched against Goguryeo, suggestions that Emperor Taizong initially declined.
In spring 643, Wei died, and Emperor Taizong mourned him bitterly, authoring Wei's monument himself and, prior to Wei's death, promising to give his daughter Princess Hengshan in marriage to Wei's son Wei Shuyu (魏叔玉). Later in spring, Emperor Taizong commissioned 24 portraits at Lingyan Pavilion to commemorate the 24 great contributors to his reign.
Contacts with the Byzantine Empire
The Old Book of Tang and New Book of Tang mention several embassies made by Fu lin (; i.e. the Byzantine Empire), which they equated with Daqin (which may refer to the Roman Empire or Middle East), beginning in 643 with an embassy sent by the king Boduoli (波多力, i.e. Constans II Pogonatos) to Emperor Taizong, bearing gifts such as red glass and green gemstones. These histories also provided cursory descriptions of Constantinople and its walls, as well as how it was besieged by Da shi (大食; the Arabs of the Umayyad Caliphate) and their commander "Mo-yi" (摩拽; i.e. Muawiyah I, governor of Syria before becoming caliph), who forced the Byzantines to pay tribute. Henry Yule highlights the fact that Yazdegerd III (r. 632–651), last ruler of the Sasanian Empire, sent diplomats to China for securing aid from Emperor Taizong (considered the suzerain over Ferghana in Central Asia) during the loss of the Persian heartland to the Islamic Rashidun Caliphate, which may have also prompted the Byzantines to send envoys to China amid their recent loss of Syria to the Muslims. Tang Chinese sources also recorded how Sassanid prince Peroz III (636–679) fled to Tang China following the conquest of Persia by the growing Islamic caliphate.
The expansion of China's power into Central Asia under Emperor Taizong seems to have been noticed in the West. Theophylact Simocatta, a Byzantine Greek historian during the reign of Heraclius (r. 610–641), wrote that Taugast (or Taugas; Old Turkic: Tabghach, from Tuoba, the Xianbei clan of Northern Wei), was a great eastern empire in the Far East that ruled over Turkic people, with a capital city roughly 1,500 miles northeast from India that he called Khubdan (from the Turkic word Khumdan, meaning, Chang'an), where idolatry was practiced but the people were wise and lived by just laws. He depicted the Chinese empire as being divided by a great river (i.e. the Yangzi) that served as the boundary between two rival nations at war, yet during the reign of Byzantine Emperor Maurice (582–602 AD) the northerners wearing "black coats" conquered the "red coats" of the south (black being a distinctive color worn by the people of Shaanxi, location of the Sui capital Sui Chang'an, according to the 16th-century Persian traveler Hajji Mahomed, or Chaggi Memet). This account may correspond to the conquest of the Chen dynasty and reunification of China by Emperor Wen of Sui (r. 581–604). Simocatta names their ruler as Taisson, which he claimed meant Son of God, either correlating to the Chinese Tianzi (i.e. Son of Heaven) or even the name of the contemporary ruler Emperor Taizong.
Succession dispute
Also in 643, Emperor Taizong would see major turmoil among his own closest family. In spring 643, his son Li You (李祐) the Prince of Qi, angry over restrictions that his secretary general Quan Wanji had often placed on him, killed Quan and declared a rebellion. Emperor Taizong sent Li Shiji against Li You, but before Li Shiji could engage Li You, Li You was captured by his own subordinate Du Xingmin (杜行敏) and delivered to Chang'an, where Emperor Taizong ordered him to commit suicide and executed 44 of his associates.
The death of Li You drew out news of another plot. Li Chengqian, who had been fearful that Emperor Taizong would eventually remove him and replace him with Li Tai, had begun to conspire with Hou Junji, Li Yuanchang (李元昌) the Prince of Han (Emperor Taizong's brother), the general Li Anyan, and his brothers-in-law Zhao Jie and Du He (杜荷, Du Ruhui's son) to overthrow Emperor Taizong. During the investigations in the aftermaths of Li You's rebellion, one of the co-conspirators, Li Chengqian's guard Gegan Chengji, was implicated by association, and in order to save himself, he revealed Li Chengqian's plot. Emperor Taizong was shocked by the news, and he appointed Zhangsun Wuji, Fang Xuanling, Xiao Yu, and Li Shiji, along with the officials in charge of the supreme court and the legislative and examination bureaus of the government to carry out a joint investigation. At the suggestion of the mid-level official Lai Ji, Emperor Taizong deposed, but did not kill, Li Chengqian, while ordering Li Yuanchang to commit suicide and executing Hou Junji, Li Anyan, Zhao, and Du.
Taizong's eldest son chose to speak Turkic, dress in Turkic clothes and even set up a tent in his residence in imitation of a Turkic khan. Taizong removed him from the position of heir apparent and chose as his successor Li Zhi, who embraced Han Chinese cultural heritage.
After Li Chengqian was deposed, Emperor Taizong briefly promised Li Tai that he would be made crown prince. However, as the investigations continued, Emperor Taizong came to the belief that Li Chengqian's downfall was driven by Li Tai's machinations, and therefore resolved to depose Li Tai as well. At Zhangsun's suggestion, Emperor Taizong created a younger son, Li Zhi the Prince of Jin (who, like Li Chengqian and Li Tai, were born of Empress Zhangsun), crown prince, who was considered kinder and gentler, while exiling Li Chengqian and Li Tai. However, starting later that year, Emperor Taizong began to doubt whether Li Zhi's personality was sufficiently strong to serve as emperor, and he toyed with the idea of making another son, Li Ke the Prince of Wu, a son of his concubine Consort Yang (Emperor Yang of Sui's daughter), crown prince, but did not do so due to strong opposition by Zhangsun Wuji.
Meanwhile, coming to the belief that he made an ill-advised promise to Yinan to give him Princess Xinxing in marriage, Emperor Taizong demanded a large amount of bride price – 50,000 horses, 10,000 cows and camels, and 100,000 sheep—a price that Yinan agreed to, but could not immediately collect and deliver. Emperor Taizong used it as an excuse to cancel the marriage agreement. Meanwhile, as Wei Zheng had, prior to his death, recommended Hou Junji and Li Chengqian's staff member Du Zhenglun as chancellors, Emperor Taizong came to suspect that Wei was part of the plot as well. He destroyed the monument he had authored for Wei and cancelled the betrothal between Wei Shuyu and Princess Hengshan.
Campaign against the Karasahr
In 644, with Yanqi's king Long Tuqizhi, who had assisted the Tang campaign to conquer Gaochang, turning against Tang and allying with the Western Turks, Emperor Taizong sent the general Guo Xiaoke (郭孝恪), the commandant at Anxi (安西, i.e., Gaochang) to launch a surprise attack on Yanqi. Guo caught Long Tuqizhi by surprise and captured him, making his brother Long Lipozhun regent. (The Western Turkish viceroy Ashina Quli (阿史那屈利) subsequently captured Long Lipozhun and briefly occupied Yanqi, although he then, not wanting a direct confrontation with Tang, withdrew, and the Yanqi nobles made Long Tuqizhi's cousin Long Xuepoanazhi king.)
Goguryeo-Tang War
Also in 644, with Goguryeo attacking Silla and Silla requesting aid, Emperor Taizong decided to prepare for a campaign to conquer Goguryeo. He arrested the emissaries that Yeon sent to the Tang court, accusing them of disloyalty to King Yeongnyu. By winter 644, the mobilization was in full force. (Apparently because of Tang's preparation to attack Goguryeo, however, the reconstituted Eastern Turkish people, fearing an attack from Xueyantuo at a time that Tang would be ill-equipped to assist, panicked and abandoned their khan Li Simo, fleeing into Tang territory. Emperor Taizong reabsorbed the Eastern Turks into Tang, while making Li Simo a general in his army.)
In spring 645, Emperor Taizong departed from Luoyang and led the troops northeast, behind a vanguard of 60,000 commanded by Li Shiji and Li Daozong. At the same time, Zhang Liang led the other 40,000 from sea. By summer 645, Tang forces had captured Yodong Fortress (, in modern Liaoyang, Liaoning), and headed southeast toward the Goguryeo capital Pyongyang. Emperor Taizong personally led about 30,000 Tang and tribal forces and defeated a 150,000 force commanded by two Gogureyo generals and then put Ansi (安市, in modern Anshan, Liaoning) fortress under siege.
However, the capable defense put up by Ansi's commanding general stymied Tang forces and, in late fall, after suffering some casualties, with winter fast approaching and his food supplies running out, Emperor Taizong withdrew. He much regretted launching the campaign and made the comment, "If Wei Zheng were still alive, he would never have let me launch this campaign." He reerected the monument he authored for Wei and summoned Wei's wife and children to meet him, treating them well.
Campaign against Xueyantuo and conquest of the Kucha
Meanwhile, in the aftermaths of the Goguryeo campaign, Xueyantuo's Duomi Khan Bazhuo (son of Yinan, who had died earlier in 645) launched attacks against Tang's border prefectures, with largely inconclusive results. In spring 646, the Tang generals Qiao Shiwang and Zhishi Sili counterattacked, defeating Bazhuo's forces, causing him to flee. His vassals Huige, Pugu (僕骨), and Tongluo tribes took the opportunity to rebel and attack him. Hearing this, Emperor Taizong launched a major attack, commanded by Li Daozong, Ashina She'er, Zhishi Sili, Qibi Heli, Xue Wanche, and Zhang Jian, against Xueyantuo. With Xueyantuo under attack from multiple sides, Bazhuo was killed by Huige forces, and the remaining Xueyantuo people fled and supported Bazhuo's cousin Duomozhi as Yitewushi Khan, but soon offered to submit to Tang. Emperor Taizong sent Li Shiji toward Duomozhi's location, with the direction to either accept his submission or destroy him. Duomozhi surrendered and was taken to Chang'an, ending Xueyantuo's rule over the region. The other tribes formerly submissive to Xueyantuo offered Emperor Taizong the title of "Heavenly Khan" and thereafter largely became submissive to Tang. Tang nominally established seven command posts and six prefectures over the region. (Huige's khan Yaoluoge Tumidu, while submissive to Tang, for some time tried to take control over the region himself, but was subsequently assassinated in 648, and there would be no other organized attempt by Huige to take over the region until for about another century.)
After the victory over Xueyantuo, Emperor Taizong again turned his attention toward to Goguryeo, cutting off relations once more and considering another campaign. Under suggestions by some of his officials, he decided to launch harassment campaigns against Goguryeo's northern region on a yearly basis, to weaken Goguryeo gradually. The first of these campaigns was launched in spring 647, with Li Shiji and Niu Jinda in command, and would reoccur. All this was in preparation of another campaign in 649 with forces totaling 300,000, but Taizong died before this campaign and the campaign was stalled into Gaozong's reign.
In 648, Emperor Taizong launched another campaign, commanded by Ashina She'er, aimed at Qiuzi, but first attacking Yanqi and killing Long Xuepoanazhi and replacing him with his cousin Long Xiannazhun. Ashina She'er advanced on Qiuzi and captured its king Bai Helibushibi, making his brother king instead.
Death
By summer of 649, Emperor Taizong was seriously ill—with some believing that his illness was caused by his taking of pills given to him by alchemists. Believing Li Shiji to be capable but fearing that he would not be submissive to Li Zhi, he demoted Li Shiji out of the capital to be the commandant at remote Die Prefecture (疊州, roughly modern Gannan Tibetan Autonomous Prefecture, Gansu), with instructions to Li Zhi that if Li Shiji hesitated, to execute him immediately, and if he did not, to recall him after Emperor Taizong's death and make him chancellor. Li Shiji, when receiving the order and realizing that his life was at stake, immediately departed for Die Prefecture. (After Emperor Taizong's death, Li Zhi would indeed recall Li Shiji and make him chancellor.) Soon thereafter, Emperor Taizong, after entrusting Li Zhi to Zhangsun Wuji and Chu Suiliang, died at his summer palace Cuiwei Palace. His death was initially kept a secret, and three days later, after his casket had been returned to Chang'an, his death was announced, and Li Zhi took the throne as Emperor Gaozong.
Monuments
After consolidating the Tang Empire, Emperor Taizong ordered six large stone panels, known as Zhaoling Liujun, to be carved with the portraits of his favorite horses. These were the horses he had ridden in overcoming his rivals and securing the borders of the country.
Emperor Taizong further composed laudatory poems for each of the six horses depicted in the stone reliefs. Constructed between 636 and 649 CE, the stone reliefs "exemplify the beauty of early Tang sculpture; the images are realistic yet powerful, created with simplicity and matured craftsmanship."
After Taizong's death, the monuments were situated along the east and west sides of the "spirit path" at the North Gate of the tomb complex named Zhaoling or Zhao Mausoleum. The six stone horse reliefs remained at the Mausoleum until the early twentieth century, when four were removed to the Beilin Museum in Xi'an, China and two were sold and subsequently donated to the Penn Museum in Philadelphia in 1921.

早年經歷
隋文帝開皇十七年十二月戊午日(598年1月23日),李世民出生於岐州武功縣,是當時擔任隋朝岐州刺史的漢族官員李淵與竇氏所生的嫡次子。竇氏有四個兒子,一個女兒,按長幼順序為:李建成、平陽昭公主、李世民、李玄霸、李元吉。
隋煬帝大業九年(613年),他的母親在涿郡(治今北京市西南)病逝,鴻臚寺治禮郎高士廉看中了李世民,把外甥女長孫氏(登基後稱長孫皇后)許配給李世民為妻。
隋大業十一年(615年),雲定興被授以左屯衛大將軍,奉命援救在雁門關被突厥始畢可汗所率大軍圍困的隋煬帝。隋煬帝派人把詔書綁在木頭上,放進汾河讓詔書順流而下,希望有人看到詔書前來救援。雲定興向各地招募願意出征的軍士,李世民那年只有十六歲,前去應募從軍,被劃歸雲定興的帳下。雲定興手下只有兩萬新兵,且多是步兵。李世民向雲定興建議:突厥敢圍困天子,是認定我們沒有援軍。不如我們把軍隊前後拉開,延綿數十里,讓敵軍白天看見旌旗招展,晚上聽見鉦鼓聲聲,誤以為大軍壓境,如此才能不戰而勝。若他們知我虛實,兩兵相接,則勝敗難料。雲定興採納了李世民的疑兵之計攻突厥,突厥兵看到隋軍浩浩蕩蕩絡繹不絕,果然以為隋軍大批救兵到,於是解圍撤退。
隋大業十二年(616年),父親李淵升任隋朝右驍衛將軍。大業十三年(617年)正月,李淵又遷任太原郡留守,李世民也跟隨到太原,李建成、李元吉和他們的異母弟李智雲留在河東郡(今山西省永濟市)。李世民時年十八。高陽魏刀兒,自號歷山飛,十分驍勇,率兵來攻太原,李淵率兵攻打,不幸深入敵陣,無法衝出重圍。李世民以輕騎突圍而進,張弓射敵,所向皆披靡,救李淵於萬眾之中。其後敵步兵又至,李淵與李世民又奮擊,大破敵軍。
唐朝建立
晉陽起兵與唐朝建立
隋朝各地反聲四起,戰火瀰漫,民不聊生。李世民準備舉義兵,于是撫恤百姓,禮遇士兵,散財養客,江湖人士、俠客義士,莫不願效死力,為李唐起義兵做好充分準備。李世民在太原結納長孫順德、劉弘基、竇琮等人,與晉陽宮監裴寂和晉陽縣令劉文靜商議勸諫父親李淵起兵反隋。東突厥支持的定楊可汗劉武周占領了太原附近汾陽宮,隋煬帝不滿李淵和馬邑郡太守王仁恭無力阻止東突厥入侵。隋煬帝要將李淵和王仁恭捉拿帶到江都問罪,還沒有成行,又將其赦免。
當時,有李氏取代楊氏的讖語,隋煬帝因為擔心李渾的侄子李敏(煬帝的姐姐楊麗華的女婿)會應讖為帝,因此誅殺了李渾家族。李淵非常擔心,在李世民、裴寂的鼓動下,決心起兵反隋。偷偷召喚李建成、李元吉從河東,女婿柴紹從長安前來太原。七月,李淵誅殺了隋煬帝派來監視他的郡丞王威、武牙郎將高君雅,接著打著「勤王定亂,迎回隋天子」的旗號,正式開始於晉陽縣起兵,並且得到李氏宗族、姻親的響應,是為晉陽起兵。李淵以李世民為敦煌郡公、右領軍都督、統右三軍。
李淵派劉文靜出使東突厥得到了始畢可汗的支持,派李建成、李世民奪取西河郡。六月,正式起兵。李淵自為大將軍,以長子李建成、次子李世民為左右大都督,以四子李元吉留守太原,進兵大興城(長安)。
七月,李世民隨李淵出征,李淵在山西霍邑與隋將宋老生二萬精兵相持於霍邑。恰值久雨糧盡,李淵與長史裴寂議論,不如暫且回太原,以後再圖謀舉事。李世民懇求李淵不要退卻。李世民說:「原本興立大義是為了拯救百姓,應當先攻入咸陽,號令天下;遇到小敵就回師,恐怕隨從起義之人將會一朝解體。回去守太原一城之地,這不過是賊寇所為罷了,怎麼能保全自己!」但是李淵不採納,催促命令引軍出發。李世民遂大哭於外,聲聞帳中。李淵召問其故,李世民說:「現在部隊憑藉正義而出動,前進、戰鬥就必定勝利,退回就一定會散夥。大家散夥於前,敵人趁機追擊於後,死亡將頃刻而至,因此悲傷。」李淵醒悟而停止撤兵。
八月,雨停,引師取霍邑。李世民怕宋老生不出戰,於是率領數名騎兵先到霍邑城下,拿著馬鞭指點比劃,好像圍城樣子,以激怒宋老生。宋老生果然發怒,開門出兵,背城列陣。李淵與李建成一起列陣於城東,李世民和柴紹列陣於城南。老生指揮兵士迅速前進,先逼近李淵,這時李建成忽然墜馬,宋老生趁機進攻,李淵與李建成部隊往後退卻。李世民自城南高地率領兩名騎兵急馳而下,衝斷了宋老生部隊,又領兵奮力進擊,敵軍大敗,各扔掉兵器逃跑。宋老生退回到城門,城上閘門放下,宋老生手拉繩子想上城,被砍死,於是霍邑平定。
到了河東,關中豪傑爭著奔赴參加義軍。李世民請求進軍入關,開永豐倉賑濟百姓,收服群雄及眾豪傑來謀取京都,李淵同意。從龍門渡黃河,先定渭北。關中有其女李三娘等人起兵響應。京都附近官民及豪傑紳士到軍門請求獻身報效義軍者日以千計,扶老攜幼,滿於麾下。李世民收納英俊,擇才而用,遠近聞者,皆來投靠。
唐軍在涇陽宿營,有優秀兵士九萬名,擊破賊寇胡人劉鷂子,兼併其部下,留下殷開山、劉弘基屯駐長安舊城。李世民自己帶兵奔赴司竹,盜賊首領李仲文、何潘仁、向善志等都來相見,停留於阿城,獲得兵士十三萬人。長安父老送牛酒到營門勞軍者不可勝數,李世民都加以慰問,然後送走他們,東西一概不收。軍令嚴肅,秋毫無犯。接著與大軍一起平定京城。
十一月,李淵攻克大興,以代王楊侑為皇帝,尊隋煬帝楊廣為太上皇,李淵自為大丞相、唐王。攻克隋大興城後,李世民官拜京兆尹、受封秦國公。618年,遷趙國公。三月,隋煬帝楊廣在江都被宇文化及所殺,五月,李淵廢黜楊侑,稱帝,改國號為唐,定都大興,易名長安,唐朝建立。李世民拜尚書令、晉為秦王。
統一中國
唐朝建立後,疆土只限于關中和河東一帶,尚未完全統治全國,因此,李世民經常出征,最終統一中國。自武德元年起,李世民親自參與四場大戰役。
• 其一,破薛舉,淺水原平定隴西薛仁果(薛舉之子),平定祖宗之地。
• 其二,敗宋金剛、劉武周,收復並、汾失地,消滅北方地方軍閥。
• 其三,在虎牢之戰中,一舉殲滅中原兩大割據勢力—河南王世充和河北竇建德集團,消除河北、河南的地方勢力。
自此李世民威望日隆,尤其是在虎牢之戰後班師返京時,受到長安軍民的隆重歡迎。武德四年十月,封為天策上將,領司徒、陝東道大行臺尚書令,食邑增至二萬戶。李淵又下詔特許天策府自置官屬,李世民因此闢弘文館,收攬四方彥士入館備詢顧問,與秦王府相結合,儼然一個小內閣。
玄武門之變與即位
618年,李淵建立唐朝為唐高祖,並立世子李建成為太子。太原起兵是李世民的謀略,高祖曾答應他事成之後立他為太子,但天下平定後,李世民功名日盛,高祖卻猶豫不決。太子李建成隨即聯合四弟齊王李元吉,共同排擠李世民。同時,高祖的優柔寡斷,也使朝中政令相互衝突,加速了諸子的兵戎相見。
此後,長兄皇太子李建成知李世民終不肯屈為人臣,而李世民也認為是自己奠下唐朝開國的基業,遂與李建成、四弟齊王李元吉猜忌日深,兩派大臣之間互相傾軋。李世民曾在李建成東宮飲酒,吐血數升,懷疑李建成下毒。
其中宰相裴寂、謀士王珪、魏徵、東宮衛士將領薛萬徹等追隨李建成、李元吉。秦府謀士杜如晦、房玄齡,將領秦叔寶、尉遲敬德、段志玄、侯君集、王君廓等跟從李世民。宰相陳叔達、朝臣長孫無忌等暗中支援李世民。其餘將領李靖、李世勣,大臣宇文士及等保持中立。
武德九年,突厥侵犯唐邊境,李建成向高祖建議由李元吉做統帥出征突厥。太子府率更丞王晊告訴了秦王:李建成想藉此控制秦王的兵馬,並準備在昆明池設伏兵殺李世民,于是李世民決定先發制人。武德九年六月初四庚申日(626年7月2日),李世民在首都長安城宮城的北門玄武門附近射殺皇太子李建成、齊王李元吉,史稱「玄武門之變」。
此後高祖讓出軍政大權予秦王,而建成、元吉則被宣布為作亂者,諸子則遭誅殺並從宗籍中除名。三天後(六月初七癸亥日,7月5日),李世民被立為皇太子,詔曰:「自今軍國庶事,無大小悉委太子處決,然後聞奏」。八月初九甲子日(9月4日),高祖退位稱太上皇,禪位於李世民。李世民登基,是為唐太宗。當年十月,追封李建成為息隱王,李元吉為海陵剌王。次年改元貞觀。642年,追複李建成為隱太子,李元吉為巢剌王,並將皇子李福過繼李建成為嗣(後來另一皇子李明也在唐高宗年間被出繼李元吉為嗣)。
貞觀之治
內修政理
貞觀二年(628年),當時的人口已因隋末戰爭而銳減,此時唐朝只有290萬戶,經太宗君臣23年的努力,社會安定、經濟恢復並穩定發展,至唐高宗永徽三年(652年),人口達到380萬戶,奠下了高宗、武則天、玄宗年間大唐盛世的基礎,史稱貞觀之治。
貞觀二年四月二十六壬寅日(628年6月3日),朔方人梁洛仁殺夏州割據勢力首領梁師都,歸降唐朝,唐朝統一全國。貞觀四年(630年),太宗令李靖出師塞北,挑戰東突厥在東亞的霸主地位。唐軍在李靖的調遣下,滅亡東突厥,太宗因此被西域諸國尊為「天可汗」。在位期間,積極推行了府兵制、租庸調制和均田制,並加強科舉制等政策。
在民族政策方面,太宗一方面擴張疆土,另一方面又接受了拓跋魏、北齊、北周二百多年的歷史現實,提出其蕃漢兼包、一視同仁的民族政策。李世民曾對他的左右大臣說:「自古帝王皆貴中華,賤夷狄,朕獨愛之如一,故其種落皆視朕如父母。」
太宗本身也是個既英武又善辯之人,但是有鑑於帝位得之不易,加上隋煬帝本人亦以雄健爾雅善辯聞名,隋卻因此鑄下滅亡的大錯,因此在位期間,太宗鼓勵群臣批評他的決策和風格。其中魏徵廷諫了200多次,在廷上直陳太宗的過失,在早朝時多次發生了使太宗尷尬、下不了臺的狀況。晚年的太宗因國富民強,納諫的器度不如初期,偶爾也發生誤殺大臣的遺憾,但是大致上仍克制、保有納言的風範。641年,唐室文成公主下嫁於吐蕃的松贊幹布。
太宗即帝位不久,按秦王府文學館模式,新設弘文館,進一步儲備天下文才。另外,太宗精擅書法,以行書寫碑,稱「飛白」,聞名後世。著名作品有《溫泉銘》、《晉祠銘》等。晚年太宗著《帝範》一書以教戒太子李治,總結了他的施政經驗,同時自評一生功過。史家曾疑太宗生前,指定以東晉書法大家王羲之所作《蘭亭集序》為陪葬品。近年據考古學家和歷史學者研究,《蘭亭集序》應該不在太宗之昭陵,而在高宗、武則天所合葬的乾陵之中。
唐太宗與身邊大臣魏徵、王珪、房玄齡、杜如晦、虞世南、褚遂良等的對答也在開元十八(730年)、十九年間被吳兢輯為《貞觀政要》一書,以發揚太宗勵精圖治的治國精神。
滅東突厥與薛延陀
武德九年(626年)八月,因唐朝發生玄武門之變,政局不穩,東突厥伺機入侵,攻至距首都長安僅40裡的涇陽(今陝西咸陽涇陽縣),京師震動。此時,長安兵力不過數萬,剛剛即位的太宗被迫設疑兵之計,親率高士廉、房玄齡等6騎在渭水隔河與頡利可汗對話,怒斥頡利、突利二可汗背約。《唐語林》記載太宗「空府庫」贈予頡利可汗金帛財物,以求突厥退軍,並與之結「渭水之盟」,突厥兵於是退去。之後,太宗勵精圖治,並且挑撥頡利、突利二可汗和突厥與鐵勒諸部的關係。627年,東突厥內部出現分裂。反對頡利可汗的薛延陀、回紇、拔也古、同羅諸部落對其變革國俗和推行的政令不滿,另立薛延陀為可汗。突利可汗也暗中與唐聯絡,並與頡利可汗決裂。同時東突厥又遇到大雪氣候,牲畜大多被凍死餓死,突厥勢力漸弱。太宗於629年八月任命李靖、李世勣、柴紹、李道宗等為行軍總管,出兵征討東突厥。630年三月頡利兵敗被俘,東突厥滅亡。唐朝在東突厥突利可汗故地設置順、祐、化、長四州都督府,頡利可汗故地置定襄都督府、雲中都督府。
東突厥滅亡後,薛延陀的真珠可汗乙失夷男接管了東突厥的故土。薛延陀表面臣服於唐朝,暗中卻擴充自己的力量。639年,太宗試圖恢復東突厥,立俟力苾可汗阿史那思摩,以抗衡薛延陀的崛起,薛延陀為避免新恢復的東突厥站穩腳跟,與其進行了多次戰爭。為保住東突厥,李世勣在641年進攻薛延陀,並取得了勝利。但是644年,趁太宗征伐高句麗的機會,薛延陀部隊發起新一輪攻勢,擊敗東突厥,迫使阿史那思摩逃回雲州。隨後,高句麗尋求薛延陀援助,但夷男希望避免與唐朝直接戰鬥。645年,夷男死後,他的兒子多彌可汗拔灼開始和唐軍作戰。646年,唐軍反擊並打敗拔灼後,薛延陀的附庸回紇、鐵勒等部落出兵,將他殺死。拔灼的堂兄伊特勿失可汗咄摩支向唐軍投降,薛延陀滅亡。太宗於鐵勒故地設六府七州:瀚海府(回紇)、金微府(僕骨)、燕然府(多濫葛)、盧山府(思結)、龜林府(同羅)、幽陵府(拔野古)。七州:皋蘭州(渾)、高闕州(斛薛)、雞鹿州(奚結)、雞田州(阿跌)、榆溪州(契苾)、蹛林州(思結別部)、窴顏州(白霫)。由燕然都護府管理,治所在陰山之麓(今內蒙古杭錦後旗),轄境東到大興安嶺、西到阿爾泰山、南到戈壁、北到貝加爾湖的整個蒙古高原。
和親吐蕃
634年,吐蕃贊普松贊幹布遣使與唐朝修好,唐朝也派臣入蕃。636年,松贊幹布派專使去長安請婚,唐朝不允許。638年,松贊幹布遂藉口唐朝屬國吐谷渾從中作梗,親自指揮大約20萬吐蕃軍,開始攻擊唐朝的松州(今四川阿壩藏族羌族自治州)。但同時松贊幹布又派遣使者到唐朝國都長安再次請求,並宣稱他們打算歡迎公主。唐太宗派侯君集為當彌道行軍大總管指揮5萬軍隊,執失思力、牛進達、劉簡協助,援救松州。與此同時,吐蕃軍正在圍困松州的首縣-嘉誠(今四川松潘),但唐軍先遣部隊在牛進達指揮下,打敗了吐蕃軍。唐軍在松州大勝吐蕃軍,但唐朝也見識到了吐蕃的力量。640年,松贊幹布又派大臣祿東贊使唐求婚,唐太宗便以宗室之女文成公主許嫁於吐蕃贊普松贊幹布,並派禮部尚書江夏王李道宗持節護送。641年文成公主入蕃,《新唐書》記載松贊幹布親迎於柏海,文成公主進蕃時把各種漢地的生產技術轉入吐蕃。
設立安西四鎮
唐太宗滅東突厥後,開始對西域(即現代新疆和中亞地區)的西突厥以及一些鬆散結盟綠洲國家的施加軍事實力,其主要針對西突厥,以恢復兩漢以來對西域的統治。高昌王麴文泰與西突厥欲谷設聯合,阻礙西域商路,進攻唐朝的伊州。639年冬,太宗以侯君集為交河道行軍大總管,率兵出擊高昌王麴文泰。640年,唐軍至磧口,麴文泰驚懼而病死。其子麴智盛即位後不久,侯君集圍城,麴智盛降唐軍。高昌國三州、五縣、二十二城,八千戶、三萬餘人歸屬唐朝,高昌國結束。唐朝在高昌設置西州。
吐谷渾可汗伏允聽信大臣天柱王的建議,屢次侵犯唐朝的西部邊境,634年,扣留唐朝使者趙德楷,六月,太宗以段志玄為行軍總管,討伐伏允,十二月,又以李靖、侯君集、李道宗等為行軍總管,大舉討吐谷渾。635年,伏允敗走,被部下所殺。伏允之子慕容順殺死天柱王,自立為可汗,投降唐朝,太宗冊封慕容順為吐谷渾可汗。慕容順死後,636年,太宗冊封慕容順之子諾曷缽為吐谷渾可汗。
640年,唐朝在交河城設安西都護府,用以針對西突厥和管理西域。644年,西突厥的盟友焉耆攻打西州,安西都護郭孝恪為西州道行軍總管,討伐依附西突厥的焉耆,佔領焉耆,俘虜國王龍突騎支,但後來焉耆再次脫離唐朝。648年,唐太宗派遣阿史那社爾、郭孝恪率軍討伐依附西突厥的焉耆和龜茲(今新疆阿克蘇),征服兩國。然後疏勒和于闐歸附唐朝,將安西都護府遷至龜茲,撫寧西域,統龜茲、焉耆、于闐、疏勒四國,史稱安西四鎮。
貞觀四年,西域諸國君主在長安尊稱太宗為「天可汗」,意為天下總皇帝或天下共主。「天可汗」除了是一種對唐朝皇帝的榮銜,還是一種有實質意義的國際組織體系,以維持當時各同盟國的集體安全。
征討高句麗
642年,高句麗東部大人淵蓋蘇文殺死榮留王後立高藏為王並自封為「大莫離支」攝政。為征討淵蓋蘇文和保護唐朝的盟友新羅,唐太宗認為有必要對高句麗開戰。644年,太宗率領李世勣、李道宗、張亮和長孫無忌統軍10萬親征高句麗。645年,太宗衝破高句麗的防線準備攻打高句麗國都平壤,似乎大功在即。不料在安市(今遼寧鞍山)受阻,再也無法前行。在這之後,太宗對高句麗的進攻僅維持在一些小規模的突襲。646年,唐朝與回紇擊滅薛延陀後,647年,唐太宗令牛進達率兵從海上、李世勣率兵從陸路攻打遼東半島。648年,太宗再派薛萬徹率軍從海上攻打鴨綠江口。隨後,唐開始集結陸海部隊準備在649年再一次大規模攻高句麗。不過太宗於649年去世後,新皇帝唐高宗暫停東征的計劃。668年,高宗聯合新羅滅亡高句麗,載籍戶數69.7萬。並建立安東都護府等加以控制遼東。
貞觀疆域
在北方,貞觀四年(630年),唐軍滅亡東突厥,漠南成為唐勢力範圍。貞觀二十年(646年),又一舉消滅了薛延陀汗國,至此大漠南北廣大地區皆為唐的勢力範圍。唐朝廷在漠北設立安北都護府,在漠南設立單于都護府,建立了南至羅伏州(今越南河靜)、北括玄闕州(後改名余吾州,今安加拉河地區)、西及安息州(今烏茲別克斯坦布哈拉)、東臨哥勿州(今吉林通化)的遼闊疆域。
在西北,貞觀四年,唐朝廷在伊吾七城設立西伊州,開始經營西域。貞觀二十二年(648年),郭孝恪擊敗龜茲國,把安西都護府治所遷至龜茲。
在東北,644年唐太宗征討高句麗未果,唐高宗在668年乃聯合新羅滅高句麗,設立安東都護府。
在青藏高原上,吐蕃日漸興起,至六世紀末與吐谷渾、蘇毗為高原上三大勢力。七世紀初,贊普松贊幹布即位,統一了高原,又征服了位於西藏西部的蘇毗、阿里地區的羊同和尼婆羅(今尼泊爾)。松贊幹布於634年遣使與唐朝修好,唐朝也派臣入蕃。636年,松贊幹布派專使去長安請婚,唐朝不允,638年,松贊幹布遂藉口唐朝屬國吐谷渾從中作梗,出兵入侵吐谷渾,唐軍在松州大勝吐蕃軍。640年,松贊幹布又派大臣祿東贊使唐求婚,唐太宗便以宗室之女文成公主許嫁於吐蕃贊普松贊幹布,並派禮部尚書江夏王李道宗持節護送,吐蕃贊普遂接受唐朝的冊封。
晚年失算
漸不克終
面對自己空前的文治武功,太宗到晚年也出現一些過失。首先納諫不如貞觀早期積極,比如貞觀十年,魏徵發現他「漸惡直言」。其次奢侈之風日重。不過晚年他還是能反省自己過度奢靡的錯誤。司馬光說唐太宗:「好尚功名,不及禮樂,父子兄弟之間,慚德多矣」。同時,太宗晚年也由早年的清靜轉為奢縱,營建宮殿,計劃封禪泰山等,並自辯「百姓無事則驕逸,勞役則易使」,魏徵因此諫到「恐非興邦之至言,豈安人之長算?」不過由于太宗晚年能夠清醒認識自己的問題,所以也能進行調整,因此雖然太宗晚年存在這些過失,最終沒有出現敗亡的危機,「功大過微,故業不墮」,維持了貞觀之治的局面。
諸子奪嫡
《資治通鑑》記載,太宗貞觀十七年廢太子李承乾之後、改立李治為皇太子之前,李世民之三子一弟(長子李承乾、四子李泰、五子李祐、及七弟李元昌)俱謀取帝位,致太宗心灰意冷之曲折,史載:「承乾既廢,上御兩儀殿,群臣俱出,獨留長孫無忌、房玄齡、李世勣、褚遂良,謂曰:『我三子一弟,所為如是,我心誠無聊賴!』因自投於床,無忌等登前扶抱,上又抽佩刀欲自刎,遂良奪刀以授晉王治。」
去世
貞觀二十二年(648年)正月,唐太宗撰寫《帝範》十二篇頒賜給太子李治。貞觀二十三年(649年),唐太宗得了痢疾(一種傳染病),醫治最終無效(一說是服用天竺長生藥無效),命李治到金掖門代理國事。貞觀二十三年五月二十六日(649年7月10日),唐太宗李世民崩逝于終南山翠微宮含風殿內,享年五十一歲,在位二十三年,初謚文皇帝,廟號太宗,唐高宗上元元年(674年)加謚文武聖皇帝,唐玄宗天寶八年(749年)加謚文武大聖皇帝,天寶十三年(754年)加謚文武大聖大廣孝皇帝,安葬於唐昭陵(位于今中國陝西省禮泉縣東北50多里山峰上)。
評價
• 《貞觀政要》贊貞觀之治:官吏多自清謹,王公妃主之家,大姓豪猾之伍,無敢侵欺細人。商旅野次,無複盜賊,囹圄常空,去年犯死者僅二十九人。又頻致豐稔,米斗三錢,馬牛布野,外戶不閉,行旅自京師至于嶺表,自山東至于滄海,皆不齎糧,取給于路。入山東村落,行客經過者,必厚加供待,或發時有贈遺。此皆古昔未有也。

• 朱熹與陳亮書:「太宗之心,則吾恐其無一不出于人慾也。直以其能假仁假義,以行其私。而當時與之爭者,才能知術既出其下,又不知有仁義之可飭。是以彼善于此,而得以成其功爾。」「論後世人,不當盡繩以古人禮法。畢竟高祖不當立建成。」「太宗功高,天下所系屬,亦自無安頓處,只高祖不善處置了。」
• 文天祥《古代狀元卷:文天祥殿試卷》:太宗全不知道、閨門之恥、將相之誇、末年遼東一行、終不能以克其血氣之暴、其心也驕。
• 元朝戈直在《貞觀政要》集論中說:「夫太宗之於正心修身之道,齊家明倫之方,誠有愧於二帝三王之事矣。然其屈己而納諫,任賢而使能,恭儉而節用,寬厚而愛民,亦三代而下,絕無而僅有者也。後之人君,擇其善者而從之,其不善者而改之,豈不交有所益乎!」這裡所說,太宗在正心修身,齊家明倫方面,有愧于二帝三王之事,主要是指太宗與其兄李建成的皇位之爭。
• 明朝官修皇帝實錄《明太祖實錄》記載,明太祖朱元璋在洪武七年八月初一日(1374年9月7日),親自前往南京歷代帝王廟祭祀三皇、五帝、夏禹王、商湯王、周武王、漢高祖、漢光武帝、隋文帝,唐太宗、宋太祖、元世祖一共十七位帝王,其中對唐太宗李世民的祝文是:「惟唐太宗皇帝英姿蓋世,武定四方,貞觀之治,式昭文德。有君天下之德而安萬世之功者也。元璋以菲德荷天佑人助,君臨天下,繼承中國帝王正統,伏念列聖去世已遠,神靈在天,萬古長存,崇報之禮,多未舉行,故于祭祀有闕。是用肇新廟宇于京師,列序聖像及歷代開基帝王,每歲祀以春、秋仲月,永為常典。今禮奠之初,謹奉牲醴、庶品致祭,伏惟神鑒。尚享!」
• 明憲宗在命儒臣訂正重刊《貞觀政要》時寫道:「太宗在唐為一代英明之君,其濟世康民,偉有成烈,卓乎不可及已。所可惜者,正心修身,有愧于二帝三王之道,而治未純也。」
• 毛澤東評價李世民說:「自古能軍無出李世民之右者,其次則朱元璋耳。」
• 王仲犖《隋唐五代史》:「唐代的皇帝裡,唐太宗,早年的唐玄宗,唐宣宗,都是傑出的皇帝。」「我們認為舊日的封建歷史家對『貞觀之治』是渲染得有點過分的。……固然,在唐太宗統治的二十多年間,人口有了較大的增長,但比之隋極盛時戶數,還不到二分之一。」「魏徵疏文中也說到:『今自伊洛以東,暨于海岱,灌莽巨澤,茫茫千里、人煙斷絕,雞犬不聞。道路蕭條,進退艱阻。』」「封建歷史家把貞觀時期當作理想的太平盛世,和實際情況是有很大距離的。」
• 呂思勉《隋唐五代史》:「唐太宗不過中材,論其恭儉之德,及憂深思遠之資,實尚不如宋武帝,更無論梁武帝;其武略亦不如梁武帝,更無論宋武帝,陳武帝矣!」
出生年月爭議
據《貞觀政要》李世民的生日是十二月癸丑,據《資治通鑑》李世民的生日是十二月癸未,據《舊唐書》李世民生于隋開皇十八年十二月戊午(599年1月23日),因此李世民的生日應為十二月份。據《舊唐書》李世民卒年五十二歲,其弟李玄霸無考;據《新唐書》李世民卒年五十三歲,其弟李玄霸年十六歲死于隋大業十年(614年),則李玄霸生卒年為公元599-614年,而李世民生卒年為公元597-649年;李世民以十二月出生,李世民生卒年月為598年1月-649年7月,與李玄霸(599-614)為同母兄弟。《新唐書》推翻了《舊唐書》關于李世民的生卒年月,增加了李玄霸的生卒年,使李世民與李玄霸的生卒更可信。胡如雷著《李世民傳》即以《新唐書》為依據,考証李世民的出生年月為隋開皇十七年十二月戊午(598年1月28日)。
《新唐書》增加了李玄霸的生卒年歲,補正了李世民的生卒年歲,補充了《舊唐書》中沒有的珍貴史料,《新唐書》與《舊唐書》同被列為《二十四史》之欽定官史。據胡如雷考証:「李世民生于開皇十八年十二月之說亦難成立,因竇氏在不到十三個月的時間裡先後兩次生子的可能性雖然不能完全排除,但就常情而言,這種可能性也不大」。根據李世民同母弟李玄霸十六歲時死于大業十年,而倒推出李玄霸生于開皇十九年,所以若李世民生于開皇十八年十二月,則李玄霸最遲生于開皇十九年十二月,兩兄弟生辰過近,不太可能。
軼事
觀史書己
貞觀九年十月,即李淵死後五個月,李世民第一次要求觀覽《起居注》,未遂。
《貞觀政要·卷七·論文史第二十八》記載:貞觀十三年,褚遂良為諫議大夫,兼知太宗《起居註》。唐太宗欲查看起居註,褚遂良以「不聞帝王躬自觀史」為由拒絕了。唐太宗說:「朕有不善,卿必記耶?」褚遂良說:「臣職當載筆,何不書之?」黃門侍郎劉洎進言:「人君有過失,如日月之蝕,人皆見之。設令遂良不記,天下之人皆記之矣。」《舊唐書·褚遂良傳》和《資治通鑑·唐紀十二》也載有此事。
次年(640年),唐太宗再度要求看《起居注》,宰相房玄齡等人就刪減整理國史,撰寫成《高祖實錄》和《太宗實錄》各二十卷。當太宗見到「六月四日事,語多微文」——指史官對當年玄武門事變內容含糊其辭,多有隱諱文飾之語,便以當年房玄齡勸他政變時「遵周公之事,外寧區夏,內安宗社」的說法,向房玄齡表示:不必替他遮遮掩掩,反正玄武門事件本來就是像「周公誅管、蔡,季友鴆叔牙」之義舉,目的是為了「安社稷、利萬民」,要求「削去浮詞,直書其事」。《資治通鑑·唐紀十三》亦有記載。
這一行為遭到章太炎指責:「太宗即立,懼於身後名,始以宰相監修國史,故兩朝《實錄》無信辭。」呂思勉、黃永年等學者也附和章太炎的觀點,認為唐太宗對史書記載有所修飾。
太宗懷鷂
唐代劉餗《隋唐嘉話》載,太宗曾經飼養過一隻鷂,十分喜愛它,經常把它架在手臂上玩賞。一次看到魏徵前來奏事,就把鷂藏在了懷裡。魏徵看出端倪,匯報事情時就順勢向太宗講述古代帝王由于安逸享樂而亡國的故事,暗中勸諫太宗。魏徵奏事時故意拖了很久,鷂最終被捂死在了太宗懷裡。
武功
《大唐新語·卷一》載,太宗繼位後曾在苑囿內狩獵,一群野豬從森林中衝出。太宗舉弓四箭射殺了四隻,但還是有一頭雄野豬向馬匹直衝而來。吏部尚書唐儉慌忙下馬,與之搏鬥。太宗拔劍砍死野豬,笑著對唐儉說,「天策長史,不見上將擊賊耶?何懼之甚!」唐儉當即回答道:「漢祖以馬上得之,不以馬上理之。陛下以神武定四方,豈復逞雄心於一獸!」太宗覺得唐儉說得有理,於是停止了狩獵。
尚書令
由於唐太宗在即位前曾當過尚書令,故當太宗做皇帝後,大臣多不敢任其職,於是之後這個職務就幾乎不授人,尚書省的長官就只設左、右僕射,後用其他官員以「同中書門下三品」的頭銜參預朝政,執行宰相職務。至高宗時,又用低級官員以「同中書門下平章事」的頭銜參預朝政,執行宰相職務。左、右僕射成了聽令執行的官員,不能參加大政,唐中宗神龍政變復闢之後,僕射就非宰相職務。中書令、侍中在安史之亂後也不常設了。同中書門下平章事成了宰相最普遍的名稱。
改名
《舊唐書·本紀第二:太宗上》記載,李世民四歲時,其父李淵任岐州刺史,有一書生自稱善相,拜訪李淵說:「公貴人也,且有貴子。」見到李世民時又說:「龍鳳之姿,天日之表,年將二十,必能濟世安民矣。」李淵害怕這話走漏,派人去追殺書生,書生卻忽然失蹤了。於是李淵就取「濟世安民」之意給李世民命名。
書法
李世民酷愛書法,其書法以隸書見長,並且酷愛書法名品《蘭亭序》(即《蘭亭集序》,王羲之書法珍品,王羲之的字十分多變,就一「之」字就有十數種變化之多),相傳當年某大臣見太宗似有鬱結難紓,問之原因,知道其欲得《蘭亭序》,於是便與辯才和尚(王羲之當年墨寶輾轉傳至其七世孫智永,智永出家為僧,又將墨寶傳予其弟子辯才和尚)鬥智最後終於為李世民獲得。而王羲之本願並不想《蘭亭序》落入君王之手成為陪葬品。但最後結果事與願違,《蘭亭序》最終成為唐太宗的陪葬品。
救駕
據新舊唐書太宗本紀,李世民十六歲時參軍,跟隨隋將雲定興,一次隋煬帝楊廣被圍,雲定興軍負責救駕,李世民獻計,故佈疑陣,嚇退敵軍,救回天子。

家庭
家世
唐太宗李世民的祖先
家族血統
陳寅恪認為李唐先世雖為漢人,但在李虎之後,其家族長期與胡人通婚,混有胡族血統,其祖母與其母親皆出身鮮卑,李世民本人擁有胡族血統為明確事實。這個說法得到錢穆、薩孟武,岑仲勉也有類似意見。根據《新修本草》記載,嚴耕望推論李世民可能擁有胡人血統。
