After the death of Emperor Sima Yan of Jin Dynasty, Emperor Sima Zhong of Jinhui succeeded to the throne. He is the emperor of "why not eat minced meat" and can't control the political situation at all. Queen Jia Nanfeng wanted to monopolize the power after reading all the spring scenery in the world, and sent troops to hunt down Yang Jun, the concubine in charge of state affairs, which triggered the "Eight Kings Rebellion" in history, and the ruling class launched an extremely cruel attack and killing for the highest power. Si Marui is relatively distant in the royal family, and his father is a mediocrity in the royal family, so he has no advantage in the power struggle between kings. Therefore, in the Eight Kings Rebellion, he didn't have any ambitions, just died in the theater, watching the kings of Sima's family killed one by one. His neighbor, Sima Yue, the king of the East China Sea who is alienated by blood, is ambitious, and he is also caught. Since then, Si Marui has been appointed as General Pingtung, supervising the military in Xuzhou and staying in Xiapi, where he was caught in the wave of power struggle. In the fifth year of Jia (3 1 1), Sima Yue, the dictator of the East China Sea, died of illness, Luoyang was captured by the Xiongnu army, and Sima Chi, the Emperor of Jin Huai, was captured and immediately killed in Pingyang. Sima Ye, the Emperor Wu of Jin Dynasty in Chang 'an, ordered Si Marui, Liu Kun and other 700,000 troops to attack Pingyang in three ways. As a result, Si Marui, the main force of this war, disobeyed orders at the instigation of the cremation. In the fourth year of lite (3 16), Chang 'an fell, the Jin Emperor died, and the Western Jin Dynasty perished. The news of the killing of Emperor Wu of Jin reached Jianye, and the Sima Liao family went to the table to persuade Si Marui to be emperor. In the fifth year of Jianxing (365,438+07), Si Marui became emperor in Jianye. This is the Emperor Wu of Jin Dynasty, and the Eastern Jin Dynasty was formally established. Jianye changed its name to Jiankang in order to avoid Emperor Sima Ye. Si Marui declared an amnesty, and all civil and military officials were promoted to the second level. Si Marui rebuilt and revived Jinshi. Being relatively distant by blood, he doesn't have much ambition. He probably never dreamed that he would become an emperor. He really picked up a bargain. Si Marui, the first family in China, became emperor, mainly thanks to the support of the northern gentry represented by Wang Dao, Wang Dun and others, especially the strong support of Wang Langya. You know, when he first came to Jianye, Wu people didn't take him seriously at all, and no one visited him for more than a month, which made him feel very embarrassed and disappointed, and simply "wasted things with wine." Wang Dao and Wang Dun, who came from the largest family in the world, are very appealing. They judged the situation and thought that Si Marui had a bright future, so they fully supported him. They took advantage of the citizens' meeting on March 3rd to ride behind Si Marui respectfully with other celebrities to set off Si Marui's lofty position. Then, according to Wang Dao's plan, Si Marui made many Jiangnan celebrities, such as Gu Rong and He Xun, embark on their official careers, which made Jiangnan aristocratic families support Si Marui in succession. At that time, there was a saying among the people that "the king and the horse, * * * the world", which meant that the mountains and rivers in the Eastern Jin Dynasty were owned by Wang and Sima. So why are Wang Dao and Wang Dun so powerful that they can stir up the world? Because they come from the Langya Wang family, which is a prime minister family and the first aristocratic family in China, spanning the Han Dynasty, Wei, Jin, Southern and Northern Dynasties. According to documents, the descendants of this family are all melons, including Wang Xiang, the most filial, Wang Yan, a celebrity known as the leader of the Eight Diagrams, Wang Dao, a famous calligrapher who created half of the Eastern Jin Dynasty, and Wang Xizhi, a group of kings who passed the imperial seal to the new emperor of the Southern Dynasties ... They interpreted a family history together. As for himself, he is a little weak. He knows very well that he can't sit on the throne without the support of Wang Langya and other big families, and the return of Wang will greatly affect the fate of the rule. So he can only accept the political result of "the king and the horse, * * * the world".
