The Southern Song Dynasty poet Xin Renjie has a popular poem "Yong Yu Le Jingkou Beiguting Huaigu", and the upper piece of the word is: Thousands of ancient rivers and mountains, heroes do not find Sun Zhong's plot. Dance hall song stage, the wind is always blown, the rain blows away. Slanting grass trees, ordinary alleys and strange, humane slaves once lived. Think of that year, Jinge iron horse, swallowed like a tiger.
The slave mentioned here refers to a heroic figure from the grassroots to the emperor in ancient China, who was the first emperor of the Southern Dynasty during the Southern and Northern Dynasties, Liu Yu, the Emperor of the Song Dynasty.
After the Battle of Shuishui in 383, the north was once again divided, and war swarmed. The Eastern Jin Dynasty in the south was not revitalized by its victory over Former Qin. The supreme ruler, represented by Sima Shi, indulged in wine, favored the left side of the river, deposed the virtuous subjects, and reused adulterers, which made the internal contradictions between class contradictions, ethnic contradictions, and ruling classes increasingly intensify.
In this turbulent era, the tide of history pushed Liu Yu, the originally unknown representative of the Hanmen shu people and the landlord class, onto the political stage and performed a mighty and majestic drama.
In 420, Liu Yu deposed the Jin Emperor, and the Jin Dynasty established by Sima Shi was declared extinct. The first thing he did when he founded the country was to break the custom of Cao Pi treating Emperor Xian of Han kindly, Sima Zhao treating Liu Chan with courtesy, and Sima Yan properly placing Sun Hao, and wiping out all the imperial Sima clans.
This move set a very bad precedent, and after that, most of the founding monarchs raised their butcher knives to cut the grass and remove the roots, and all the last emperors basically ended up in the fate of death and destruction of the country. Why kill the killer?
Liu Yu hated the incompetent Sima clan for causing the "Five Hu Chaohua", such a psychological estimate is there, after all, watching such an Eastern Jin Dynasty regime with no ambition for the Northern Expedition rule Jiangnan, and the Hu people in the northern land are raging, the Han people are suffering, any slightly bloody will be indignant, so he reformed the Sima family's life, and he Liu Yu sat in Jiangnan to wave the Northern Expedition.
Liu Yu carried out the Northern Expedition many times, not only defending the territory of the country, but also expanding the territory of the Southern Song Dynasty, and even Wang Fuzhi praised him.
But the dynasty will always come to an end, especially during the northern and southern dynasties, when dynasties changed frequently, although Liu's descendants also wanted to save Jiangshan, but they were still destroyed. Liu Yu had originally killed the traitors who controlled the government, but he was killed by Xiao Daocheng, who held military power, and Xiao Dao established his younger brother as a puppet emperor.
However, the Southern Song still had some loyal courtiers, although their uprisings were suppressed by Xiao Daocheng's army, and then when Xiao Daocheng prepared everything, he directly deposed the emperor and established himself as emperor, just like Liu Yu usurped the Jin Dynasty, and the Southern Song Dynasty did not escape the fate of extinction.
