About Li Siyuan

Lived 867 – 933 (aged 65–66). Li Siyuan was a politician.

Li Siyuan (李嗣源, later changed to Li Dan (李亶) ) (10 October 867 ), also known by his temple name as the Emperor Mingzong of Later Tang (後唐明宗), was the second emperor of the Later Tang dynasty of China, reigning from 926 until his death. He was an ethnic Shatuo originally named, in the Shatuo language, Miaojilie (邈佶烈).

Adopted by the ethnic Shatuo ruler Li Keyong of the Former Jin dynasty, Li Siyuan became a trusted general under both Li Keyong and Li Keyong's successor Li Cunxu (Emperor Zhuangzong), the Later Tang founder. In 926 he seized power by a coup d'état when a mutiny called the Xingjiao Gate Incident killed Li Cunxu, and ruled with both discipline and compassion for the next seven years. Despite an abundance of natural disasters, his reign was markedly more peaceful than the half-century preceding it.

Background Li Siyuan was born with the Shatuo name of Miaojilie in 867 in Yingzhou (應州; present-day Ying County, Shanxi), without a surname like his nomadic Turkic ancestors. His father, referred in Chinese historiography books by his Chinese name Li Ni (李霓), was a military general under Li Guochang, the Shatuo leader in the region who received the imperial surname Li for contributions to the Tang dynasty court. He was Li Ni's oldest son. His mother was a Lady Liu, who was later honored with the title of Lady of Song. Some time after Li Ni's death (predating Li Guochang's and Li Keyong's defeat) in 879 (when Miaojilie was 12), Li Guochang took Miaojilie as a bodyguard, having been impressed by the son's mounted archery skills reminiscent of the father. It was said the teenager never missed when he aimed at hovering birds on hunting trips. In 883, Li Keyong was made the military governor (Jiedushi) of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi) after a major victory against Qi.

Miaojilie had been serving Li Keyong, who, finding the quiet youngster earnest and dedicated, adopted him as a son and bestowed him the Chinese name Li Siyuan. A couple of years later, Li Siyuan demonstrated his military leadership again by leading a force to quell a rebellion, capturing its leader Wang Bian (王弁). Once at a gathering, generals started bragging about their accomplishments, when Li Siyuan interrupted and spoke slowly: "You sirs, use your mouths to attack enemies. I use my hands to attack enemies." Everybody fell silent.

In 907, Zhu seized the throne from Tang's last emperor Emperor Ai, ending Tang and starting a new state/dynasty of Later Liang. Li Keyong, as Prince of Jin bestowed by Tang dynasty, along with several other regional governors and warlords (Li Maozhen the Prince of Qi, Yang Wo the Prince of Hongnong, and Wang Jian the Prince of Shu), refused to recognize Zhu as emperor and continued to consider themselves as vassals of the now defunct Tang state — but were in effect, rulers of their own independent states by this point. Li Siyuan continued to serve his adoptive father in this new Jin state. Shortly after, Zhu sent his general Kang Huaizhen (康懷貞) to command an army to attack Jin's Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi), then under Li Sizhao's governance. Zhu himself then followed with a larger army, and the Later Liang army put Zhaoyi's capital Lu Prefecture (潞州) under intense siege, fully intent on capturing it. Li Keyong sent a relief force, under the overall command of Zhou Dewei, with Li Siyuan, Li Siben (李嗣本, another adopted son of Li Keyong), Li Cunzhang (李存璋), and An Jinquan (安金全) serving under Zhou, to try to lift the siege, but while the relief army was able to harass the Later Liang army, it was unable to lift the siege. Soon, the city was in a desperate position as food supplies were dwindling. During the midst of the siege, Li Keyong grew ill at Taiyuan and died in spring 908 and was succeeded as Prince of Jin by his biological son Li Cunxu.

Career under Li Cunxu

During Jin Li Cunxu decided to lead the army to relieve Lu Prefecture himself, and as he advanced there, he caught the Later Liang army, which was not expecting him to be able to come so quickly, by surprise. He had Li Siyuan lead the assault on the northeast side, and Zhou Dewei lead the assault on the northwest side. The Later Liang army surrounding the city collapsed, and the siege was lifted.

In 912, Li Cunxu launched a major campaign, intending to destroy the Yan state ruled by Liu Shouguang, with Zhou in command of the overall operations. As part of the campaign, Li Siyuan was in charge of attacking Ying Prefecture (瀛州, in modern Cangzhou, Hebei), and he was successful in getting its prefect, Zhao Jing (趙敬), to surrender. Subsequently, when Liu sent his major general Yuan Xingqin to his northern borders with the Khitan Empire to await potential aid from Khitan's Emperor Taizu, Li Cunxu sent Li Siyuan to intercept Yuan's army. Li Siyuan first attacked Wu Prefecture (武州, in modern Zhangjiakou, Hebei), and its prefect Gao Xinggui (高行珪) surrendered. Yuan then attacked Wu Prefecture, and when Li Siyuan came to its aid, Yuan tried to withdraw, but Li Siyuan subsequently engaged him eight times and forced him into surrendering. Li Siyuan took Yuan as an adoptive son and kept Yuan under his command. (Gao Xinggui's brother Gao Xingzhou, whom Gao Xinggui sent to seek aid from Li Siyuan, also joined Li Siyuan's army and subsequently often commanded Li Siyuan's guards along with Li Siyuan's adoptive son Li Congke – the son of Li Siyuan's concubine Lady Wei.) Jin forces were subsequently able to destroy Yan and add its territory to Jin. (In 915, when Li Cunxu heard of Yuan's ferocity in battle, he requested that Li Siyuan send Yuan to serve under his own personal army, and Li Siyuan, unwilling to resist the order, reluctantly sent Yuan to Li Cunxu. Li Cunxu also wanted Gao Xingzhou and tried to entice Gao with promotion offers, but Gao declined to leave Li Siyuan's command.)

In 916, when the Later Liang major general Liu Xun tried to attack Wei Prefecture (魏州, in modern Handan, Hebei), which had recently surrendered to Jin – an attack that Li Cunxu anticipated and therefore reacted to immediately – Li Siyuan and his adoptive brother Li Cunshen served as main commanders under Li Cunxu. In the subsequent battle, the Jin army crushed the Later Liang army, ending Liu's hopes of defeating Li Cunxu there. When the Later Liang military governor of Zhaode Circuit (昭德, headquartered in modern Handan) subsequently abandoned the circuit in light of Liu's defeat, Li Cunxu merged Zhaode's three prefectures, which had previously belonged to Tianxiong Circuit (天雄, headquartered at Wei) back into Tianxiong, and made Li Siyuan the prefect of Zhaode's former capital Xiang Prefecture (相州). When Jin forces subsequently approached Cang Prefecture (滄州, in modern Cangzhou), Later Liang's military governor of Shunhua Circuit (順化, headquartered at Cang), Dai Siyuan, abandoned it and fled back to Later Liang territory. Dai's officer Mao Zhang (毛璋) surrendered Cang to Jin. Li Cunxu sent Li Siyuan to pacify the region, and Li Siyuan subsequently sent Mao away to pay homage to Li Cunxu. Li Siyuan was subsequently made the military governor of Anguo Circuit (安國, headquartered in modern Xingtai). It was there where one of his officers, An Chonghui, became a key trusted staffer.

In fall 918, Li Cunxu planned to launch a major attack on Later Liang, and he gathered troops directly under his command at Wei. Zhou, Li Cunshen, and Li Siyuan all led their own troops to rendezvous with him there as well, along with troops sent by Wang Chuzhi. He crossed the Yellow River into Later Liang territory, with the intent of destroying Later Liang. Subsequently, the joint Jin forces encountered the Later Liang forces under He Gui at Huliu Slope (胡柳陂, in modern Heze, Shandong). The battle was initially a major Jin defeat, with Zhou being killed in the battle. In the confusion of the battle, Li Siyuan believed that Li Cunxu had already retreated north of the Yellow River, and therefore retreated. Li Cunxu, however, was subsequently able to turn the battle around and defeat He Gui's Later Liang forces, causing the battle to be an overall stalemate in which both sides lost over two thirds of their armies, before withdrawing back north. When Li Siyuan rendezvoused with him, Li Cunxu was displeased, believing that Li Siyuan had thought that he died and was abandoning the battle. However, as Li Congke, who got separated from Li Siyuan during the battle and ended up fighting under Li Cunxu during the second stage of the battle, had great contributions during it, Li Cunxu did not punish Li Siyuan, although he did not treat Li Siyuan with as great respect subsequently.

In spring 922, in light of a Khitan incursion, Li Cunxu made Li Cunshen the military governor of Lulong (aka You Prefecture), to defend against further Khitan attack. Li Siyuan was made the military governor of Henghai Circuit (previously known as Shunhua when under Later Liang rule), which Li Cunshen had been the military governor of, but remained with Li Cunxu's army.

During Later Tang During the destruction of Later Liang In summer 923, Li Cunxu, then at Wei Prefecture, declared himself the emperor of a continuation of Tang — historically known as Later Tang. However, at the same time as his declaration, the Later Tang state was facing several serious threats that caused its subjects to be distressed about its prospects — the Khitan Empire was continuing to harass Lulong Circuit; Later Liang had just recently seized Wei Prefecture (衛州, in modern Puyang, different than the Wei Prefecture referred to above); and Zhaoyi Circuit, previously governed by Li Sizhao but under the control of his son Li Jitao after his battlefield death during the Zhao campaign, had just rebelled against Later Tang and pledged allegiance to Later Liang. At this juncture, though, an officer of Later Liang's Tianping Circuit (天平, headquartered in modern Tai'an, Shandong), Lu Shunmi (盧順密), defected to Later Tang, and revealed to Li Cunxu that Dai Siyuan, who was the military governor of Tianping, had left two unpopular officers, Liu Suiyan (劉遂嚴) and Yan Yong (燕顒), in defense of Tianping's capital Yun Prefecture (鄆州), and that a surprise attack on Yun could cause it to fall. When Li Cunxu consulted Li Siyuan, Li Siyuan, who had long wanted to have a specular achievement since the Battle of Huliu Slope, advocated carrying out this attack and volunteered to command his own troops. Li Cunxu agreed, and Li Siyuan thereafter led 5,000 elite soldiers and launched a surprise attack across the Yellow River, catching Liu and Yan unaware. When he quickly entered the city, Liu and Yan fled to the Later Liang capital Daliang. Li Cunxu thereafter commissioned Li Siyuan as the military governor of Tianping. Subsequently, the Later Liang emperor Zhu Youzhen (Zhu Quanzhong's son) replaced Dai with Wang Yanzhang, who tried to cut off the communications between Yun and the rest of Later Tang territory north of the Yellow River by capturing the fords at Desheng and Yangliu (楊劉, in modern Liaocheng, Shandong). He captured Desheng quickly, but Yangliu's defenses held under the defense of Li Zhou (李周), and Li Cunxu was subsequently able to lift the siege on Yangliu, allowing Yun to remain in contact with Later Tang proper.

In summer 924, the Anyi Circuit (安義, i.e., formerly Zhaoyi) officer Yang Li (楊立), who had previously been trusted by Li Jitao, whom Li Cunxu had executed after his conquest of Later Liang, mutinied and seized control of Anyi's capital Lu Prefecture. Li Cunxu sent Li Siyuan to command the forces against Yang, with Yuan Xingqin — now with the imperially-bestowed name of Li Sharing — and Zhang Tingyun (張廷蘊) serving as his deputies. Zhang quickly advanced to Luo and entered it, capturing Yang and his coconspirators, before Li Siyuan and Li Shaorong could arrive. (Yang and his coconspirators were subsequently delivered to then-Later Tang capital Luoyang and executed.) After this campaign, Li Siyuan was made the military governor of Xuanwu Circuit and the commander of the Han and non-Han cavalry and infantry forces, replacing the recently deceased Li Cunshen.

During the collapse of Li Cunxu's reign Soon after Former Shu's fall, however, Li Cunxu and his wife Empress Liu came to suspect Guo Chongtao of hoarding wealth and planning to occupy Former Shu's territory to rebel himself. Empress Liu wanted to order Guo's death, and, after Li Cunxu initially refused to issue such an edict, issued her own edict to Li JIji and ordered Guo's death. Li Jiji carried the order out, leading to much shock and dissension among the imperial troops. Li Cunxu's subsequent execution of another major general, Li Jilin, only added to such dissent. Kang Yanxiao subsequently rebelled, and while his rebellion was quickly suppressed, the soldiers' dissensions continued, particularly because at that time, the Luoyang region was stricken with famine, leading to many rumors. Li Siyuan was also the subject of many rumors, leading to Li Cunxu's sending his close associate Zhu Shouyin to meet with and observe Li Siyuan. Zhu secretly informed Li Siyuan of this and stated, "Your achievements, Lord Chancellor, make your Lord comprehensive about you. You should consider trying to return to your fief to avoid disaster." Li Siyuan responded, "My heart does not sin against heaven or earth. If disasters come, I cannot avoid it. It will be my lot." It was said that several times Li Cunxu came to believe the rumors about Li Siyuan, but Li Cunxu's director of palace affairs, Li Shaohong protected Li Siyuan such that no disaster came to Li Siyuan.

Late in 927, Yang Pu, the king of Later Tang's southeastern neighbor Wu, with whom Later Tang had friendly relations, declared himself emperor. An suggested a campaign against Wu, but Li Siyuan did not approve it. Still, in early 928, An refused further emissaries from Wu, thus effectively breaking relations with Wu. Around that time, Li Siyuan considered visiting Yedu (鄴都, i.e., a new name for Xingtang), but the imperial army soldiers were displeased with yet another journey after the recent journey from Luoyang to Bian, and as a result, all kinds of rumors again started. When Li Siyuan heard of this, he decided not to visit Yedu.

Meanwhile, there was also an adversarial relationship between An and Li Congke, stemming from a time in their youths when Li Congke battered An severely after a drunken argument, despite Li Congke's subsequent apologies to An. As of 930, Li Congke was serving as the military governor of Huguo Circuit (護國, headquartered at Hezhong Municipality), and An often criticized his governance to Li Siyuan, but Li Siyuan did not listen to it. Therefore, An resolved to remove Li Congke by other means. He induced Li Congke's subordinate Yan Yanwen (楊彥溫) into refusing to allow Li Congke to return to headquarters after Li Congke was out on a hunt once. When Li Congke inquired why Yang did this, Yang responded, "It is not that I, Yang Yanwen, forgot your grace, but it is by the orders of the Office of the Chiefs of Staff that you, Lord, report to the capital." When Li Congke reported this to Li Siyuan, Li Siyuan summoned both Li Congke and Yang to the capital, hoping to inquire of the situation, but An sent an army that captured and executed Yang (i.e., killing Yang so that Yang would not have an opportunity to report him). As a result of this incident, Li Siyuan relieved Li Congke of his command and had him return to his mansion. An subsequently tried to make further false accusations against Li Congke for allegedly stockpiling weapons, but with Consort Wang protecting Li Congke, Li Congke escaped further repercussions. Around the same time, Li Congrong was created the Prince of Qin and Li Conghou the Prince of Song. Li Siyuan commissioned an imperial army, commanded by Shi Jingtang, to attack Meng and Dong. However, despite some early successes, the imperial army became bogged down in its confrontation with the two circuits, becoming stuck at Jian Prefecture (劍州, in modern Guangyuan), while the Dongchuan and Xichuan armies captured Zhaowu, Baoning, Wuxin, and Wutai (武泰, headquartered in modern Chongqing) Circuits. In late 930, An offered to head to the front to oversee the operations, and Li Siyuan agreed. However, after An left the capital, Shi, who did not favor the campaign in the first place, submitted a petition listing the reasons why the campaign was not advisable. Zhu Hongzhao, who was previously a close associate of An's and who was then the military governor of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi), also submitted a petition accusing An of planning to take over Shi's army. Li Siyuan thus recalled An, and then relieved him of his position as chief of staff made him the military governor of Huguo. After An offered to retire, Li Siyuan made his nephew Li Congzhang the Prince of Yang the military governor of Huguo, but Li Congzhang then, apparently with Li Siyuan's approval, put An and his wife to death. (Upon An's demotion, Li Siyuan restored Li Congke's privileges and restored Qian Liu's offices, blaming An for provoking Qian, Dong, and Meng.)

After An's death, Li Congrong, who previously had been respectful of An, became uncurbed in his behavior. At this time, Consort Wang and the director of palace affairs, Meng Hanqiong, were in control of the palace, and Fan Yanguang and Li Siyuan's son-in-law Zhao Yanshou served as chief of staff in An's stead, but Li Congrong was not respectful of any of them and often insulted them, causing them to be fearful and often requesting to leave the imperial government. Shi Jingtang, whose wife was not born of the same mother as Li Congrong, also had an unfriendly relationship with Li Congrong, and therefore often wanted to leave the capital as well. In late 932, when Li Siyuan considered installing a strong military governor of Hedong to defend against possible Khitan incursions, Fan and Zhao recommended Shi, and therefore Shi was commissioned as the military governor of Hedong.

Li Congrong actually had other plans. Fearing that the throne would go to his younger brother Li Conghou, whom he felt was a more favored and worthy son, he decided to act first and seize power militarily. On the next day, the ill emperor was informed by his generals and eunuchs that Li Congrong was attacking the palace gates. In disbelief, he pointed his finger upwards and cried at length. To Li Chongji (李重吉), son of his stepson Li Congke, he compared his two sons, "The fact that your father and I could emerge from obscure pasts to claim the world, it was all because he repeatedly saved me in dangerous situations. Oh, the temerity of Congrong to commit a deed so sinister!" He told the men to handle the matter themselves. boxstyle_1 = background-color: #fcc; boxstyle_2 = background-color: #fb9; boxstyle_3 = background-color: #ffc; boxstyle_4 = background-color: #bfc; boxstyle_5 = background-color: #fcb; 1= 1.
