Introduction: Xi Jian was not from the Wang clan, and in the situation of "the king and the horse sharing the world" that had been formed in the early years of the Eastern Jin Dynasty, his investment pen from the exiles under the command of Rong to quell civil strife, stabilize the situation, and toss and turn sideways in the strong forest and the door valve political toilet, and retreated from himself, which had a positive impact on the early dynasty situation of the Eastern Jin Dynasty and the establishment of the Northern Province Army later.

I. Confucians lead the troops to enter the seal with merit
Xi Shi (郗氏出高平, in present-day Heze Juye, Shandong), in the early Eastern Jin Dynasty, was not a prominent mendi, belonged to the old Confucian family, Xi Jian himself read the scriptures, did not advance the discussion, and was called Confucian. When the Hu invaded, the Xi clan did not cross south, but guarded zoushan mountain, because the displaced people gathered, and after a few years it reached tens of thousands. With the oppression of the Hu army, Xi Jian led the displaced people to move south, as the commander of the displaced people, during which there was a history of resisting Hu Xian, the armed forces were relatively strong, and the Eastern Jin Dynasty court had some regulations, afraid that they had the heart of disobedience, so although Xi Jian moved south, he was not allowed to cross the river to Jiankang. In 322, in the first year of Yongchang, Xi Jian went south to Hefei, at this time during the rebellion of Wang Dun, the broker Zhan recommended, the Jinyuan Emperor requisitioned Xi Jian, in order to use Xi Jian's strength to eliminate Wang Dun, Xi Jian also did not resign, entered Kyoto, determined to make meritorious contributions, in order to develop, but at that time, Shangshu yi title was not sick. Xi Jian himself entered the dynasty and left his displaced people in Hefei, and in order to maintain contact and prevent the imperial court from seizing troops, he frequently traveled back and forth between Jiankang and Hefei. In the same year, Emperor Yuan of Jin died and Emperor Ming of Jin succeeded to the throne, and Xi Jian conspired with Emperor Ming to attack Wang Dun, and proposed to suppress it with the troops of the displaced people, and at the same time asked Zhao Sujun, Liu Xi and other exiles to jointly suppress the rebellion.
During the Ming Dynasty, Zu Yue inherited Zu Ti's army in Yuzhou, stationed in Shouchun, disobeyed Wang Dun, but was also dissatisfied with the Eastern Jin Dynasty court, because the imperial court looked at Zu Ti's behavior coldly, and it was impractical to resist Wang Dun with Zu Yue's troops. There are also Tao Kan, but they have been sent by Wang Dun to guangzhou, and it is difficult to quench the thirst in the distant waters, and it is difficult to participate in the situation in Jing and Yang.
Before Xi Jian, the Eastern Jin dynasty court also forcibly recruited displaced people as soldiers, but they had no combat effectiveness, and when Wang Dunchu rebelled, these displaced people's armies were defeated in the next battle led by Liu Kui and Dai Yuan. Subsequently, the Eastern Jin Dynasty court relied heavily on displaced people. In order to raise supplies, Xi Jian seems to have done the work of intercepting travel and killing people and crossing goods, because the displaced people are dominant on one side and do their own thing, and the nature of the displaced people's private soldiers is relatively heavy.
Wang Dun rebelled twice, attacking from the upper reaches of the Yangtze River, the initial rebellion was during the Yuan Emperor period, the direct purpose was the Side of the Qing Emperor, with the acquiescence of Wang Dao, he killed a number of enemies of the Wang family such as Liu Kui, Diao Xie, and Dai Yuan, and then rebelled against the Ming Emperor, the attitude and situation of the various door valves were more delicate, especially Wang Dao, and this also affected Xi Jian's political attitude of going south after the rebellion. With the merits of counterinsurgency, Xi Jian gradually rose to the rank of Jiangzuo Gate Valve, and his clan was also able to rise to the level of a first-class warrior clan.
Second, the toilet door valve is stable and the situation is stable
Xi Jian moved south to be enlisted, and in addition to Ji Zhan's recommendation, Wang Dao also played a role, otherwise he would not be accepted by the imperial court. It can be seen from Xi Jian's actions that his political attitude was first and foremost the Eastern Jin Dynasty, followed by the retreat of Fold chong and humility.
In 325 AD, Emperor Ming of Jin died, Emperor Cheng of Jin succeeded to the throne, and wang Dao, Yu Liang, Xi Jian and seven others were entrusted with the edict to assist the government. The mother of Emperor Jincheng was Yu Liang's sister, so Yu Liang's status rose rapidly, and after Wang Dun's rebellion, Di Xin's wariness of the Wang clan increased, and various factors led to prominent contradictions between Yu and Wang. In order to restrain the dictatorship of the Yu clan and stabilize the political situation, Xi Jian supported Wang Dao, and is well known as the combination of Xi Jian's daughter Xi Xuan and Wang Dao's nephew Wang Xizhi, allusing to the East Bed's son-in-law.
In 328, because Yu Liang insisted on recruiting the exiled marshal Su Jun into the dynasty (actually to take his military power), Su Jun joined forces with Zu Yue to rebel and attack Jiankang, but was defeated and killed, and Xi Jian played a role in quelling the rebellion. The rebellion of Su Jun caused the ruins of Kyoto, the price of goods to rise, and the people's lack of livelihood, in order to quench the people's anger, Yu Liang said that he would go out to become an official. In 329, Yu Liang came out of the history of Yuzhou, Wang Dao regained control of the center, and his prestige reached its peak, but the Wang clan ding was already thin at this time, and the strength of the portal was not enough to support Wang Dao's power, still with the help of Xi Jian.
In 330, Tao Kan killed Guo Mo to take Jiangzhou, which was able to have both Jingjiang and Erzhou, disrupting the balance. Tao Kan pre-empted the army to depose Wang Dao, and Yu Liang and Xi Jian dissuaded Tao Kan on the grounds of "the times are in danger of the country", but the three parties agreed to jointly balance the central Wang Dao. In the end, Tao Kan failed to achieve his wishes, and Xi Jian insisted that opposition was one of them, and the other was Yu Liang's attitude, because Yu Liang and Tao Kan had accumulated grievances, and Tao Kan was in the upper reaches of yu Liang, which put pressure on Yu Liang, and the two evils were in power, and Yu Liang dissuaded Tao Kan from deposing Wang Dao.
In 340, Yu Liang prepared to depose Wang Dao, but failed because Xi Jian supported the army Jingkou to help Wang Dao.
In addition, it should also be noted that Xi Jian had some rules and regulations for Wang Dao, who had a lot of chaotic government in his last years, and Xi Jian's admonitions and specific opinions.
Overall, in addition to the rebellion of Wang Dun and Su Jun, Jiang Zuo was relatively stable for more than seventy years, and Xi Jian played a positive role in his insistence on mediation, which also created conditions for resisting the Hu people and recuperating the people's livelihood.
3. Re-stream civil
The Hu invaded, forcing the people of the north to move south, and became displaced people. Under the pursuit of Hu Qi, the displaced people generally go to the southeast of the lower reaches of the Yangtze River, that is, the area around Jingkou and Jinling, because the Yangtze River at Jingkou is tens of miles wide, and Hu Riding is difficult to reach and is relatively safe. However, the area from Jingkou to Jinling was harsh and the land was barren, and in view of the fact that xi was "in the field house and gradually gained less peace" for the displaced people of Jingkou and Jinling, under Xi Jian's long-term operation, he was able to control the political situation and economy of the three Wus with Jingkou, resist the sea and the Hu people, and objectively lay the foundation for the Beifu soldiers that Xie Xuan later built here. Gai' strength was always based on displaced people, and before his death, he was still listed as a displaced person, and his words were earnest.
4. Summary
Under the eastern Jin Dynasty's door valve politics of "the king and the horse are in the world", there can be no shi clan mendi with extreme political advantages, otherwise it will be extremely easy to leave. Xi Jian's work was mainly to maintain the balance of power between the various ethnic groups, and then to continue the Eastern Jin Dynasty. Xi Jian has never stayed in the center, his family has never obtained the highest social status, and he has not had an eunuch in succession, but his chaotic situation can deter his subordinates, and it is inseparable from his humble retreat and old Confucianism, so he died well.
