About Chapter 82 Story Synopsis: After Liu Yu, the general of the Eastern Jin Dynasty, after mastering all the power of the Jin court, listened to the prophecy, he killed the emperor Sima Dezong of the Eastern Jin Dynasty, and set Sima Dewen as the emperor, and finally forced Sima Dewen to give way to him, Sima Dewen happily took the throne, and since then the Eastern Jin Dynasty perished after 103 years of founding, Liu Yu successfully replaced the Eastern Jin Dynasty and established Liu Song in the Jiangnan region. However, the northern land was still in turmoil, and the Northern Wei Emperor Tuoba Hei established a military town on the line of the Great Wall in order to resist Rouran.

In this story, Liu Yu after years of struggle, finally ascended the throne of the emperor, opened the historical period of the Southern Dynasty in the Jiangnan region of China, the most accurate name of the Liu Song Dynasty should be called the Southern Song Dynasty, but because after the Sui and Tang dynasties, there was a Southern Song Dynasty established by Zhao Jian, so we named the Song Dynasty established by Liu Yu Liu Song Dynasty, of course, the Liu Song Dynasty is also the first of the four regimes of the Southern Song Dynasty, Song, Qi, Liang and Chen.

We talk about the division of historical periods into the Northern and Southern Dynasties, but in fact, the Southern Dynasties appeared about 20 years earlier than the Northern Dynasties. At the same time that Liu Yu replaced the Eastern Jin Dynasty, there were still the Northern Wei Dynasty, the Northern Yan Dynasty, the Northern Liang Dynasty, the Western Qin Dynasty, the Hu Xia Dynasty, etc., and the northern region was still in the Sixteen Kingdoms period, so the beginning of the Southern Dynasty did not represent the end of the Sixteen Kingdoms period, because the Southern Dynasty, as the name suggests, is the meaning of the historical dynasties in the southern region, and the Northern Dynasty is the meaning of the historical dynasties in the northern region. Although the Southern Dynasties are more than 20 years earlier than the Northern Dynasties, we will take the Sixteen Kingdoms of the Eastern Jin Dynasty as a historical period, so the difference will be made up for in 20 years, so the historical period after the Three Kingdoms period should be called so, the period of the Two Jin Dynasty and the Sixteen Kingdoms Period and the Northern and Southern Dynasties period.

Liu Yu naturally wants to be famous through the ages, because he not only created a dynasty that belonged to himself and his family, but also created an era in the Jiangnan region that was later called the Southern Dynasty. Liu Yu was in his sixties when he replaced the Eastern Jin Dynasty, he definitely didn't want to spend the rest of his life in the war, and the Eastern Jin Dynasty went through decades of infighting and the Northern Expedition, Liu Yu also inherited a battered regime from the Sima family, so Liu Yu, who knew the suffering of the people, chose the national policy of recuperation and began to govern the Jiangnan region, of course, because Liu Yu was old, there was not much time left for him, but Liu Yu still tried every means to reform the maladministration and rest the people, It can be seen that Liu Yu, who was born in a poor family, can be regarded as a very good emperor.

In fact, from the words that Sima Dewen said when he wrote the edict of the Zen throne when he was persecuted, I can also see that Liu Yu has played an indelible role in the peace and stability of the Jiangnan region, although Sima Dewen is a dead king, but the demise of the Eastern Jin Dynasty can be said to have nothing to do with Sima Dewen, since Sima Rui relied on the family to establish the Eastern Jin Dynasty, the Eastern Jin Dynasty has not had a moment of tranquility, that is, during the reign of Sima Yao, the Emperor of Xiaowu of the Eastern Jin Dynasty, under the drive of the Xie family, the Eastern Jin Dynasty had a short spring, but with the death of Xie An, the patriarch of the Xie family, the internal strife of the Eastern Jin Dynasty was rekindled, and the imperial power of the Eastern Jin Dynasty was also usurped by the Huan family.

Sima Dewen said so, copying the edict of the Zen position is also very good, but his heart is absolutely unwilling, Sima Dewen is a rare person among the rulers of the Eastern Jin Dynasty, and I think there is another reason for his statement, that is, to beg for Liu Yu, hoping that his cooperation can be exchanged for Liu Yu's grace of not killing, but the imperial influence of the Eastern Jin Dynasty is weak, Sima Dewen is completely useless to Liu Yu, and Sima Dewen is by no means a stupid and incompetent person, so he did not escape the fate of being killed in the end. We can also see from Liu Yu's killing of Sima Dewen that the handling of the deceased monarch should still follow the influence of the previous dynasty and the personal ability and mentality of the deceased monarch himself.

During the period of the Sixteen Kingdoms, the extinct nomadic regime, because its main tribe still exists, its deceased monarchs often received better treatment, and in the regime change of the Han ancestors, the deceased monarchs often did not have a good end, unless they were more able to pretend to be stupid, or willing to surrender, because the rulers of the previous and subsequent regimes were all of the same ethnic group, and there was basically no problem of imperial influence, so the rulers of the Han ancestors generally followed the principle of cutting grass and eradicating the roots. The rulers of the nomads, on the other hand, followed the principle of doing their own thing.

Just when Liu Yu usurped the throne successfully and established the Liu Song Dynasty, the emperor of the Northern Wei Dynasty Tuoba Hei who established a state in the Kwantung region was also a very good emperor, after his father Tuoba Jue was killed, he pacified the Tuoba Shao Rebellion, and at the same time sent troops to attack Rouran, he also built military towns along the line of the Great Wall. This makes it difficult to realize the strategic attempt of Rouran, who dominates the Mongolian steppe in the north, to go south to the Central Plains, so Tuoba Hei played a very important role in protecting the Northern Wei Dynasty from the invasion of northern nomads, and at the same time, because of the existence of military towns, it is difficult to have a strong nomadic tribe enter the Central Plains region, so the chaotic situation presented by the bloody period of ethnic integration during the period of the Sixteen Kingdoms period was basically over during the reign of the Northern Wei Emperor Tuoba Hei. Since the end of the Eastern Han Dynasty, the various tribes of the nomadic peoples who have continued to enter the Central Plains to develop and grow can also be safely and smoothly sinicized in the northern land.

However, with the last Xianbei Tuoba Department to enter the Central Plains during the Sixteen Kingdoms period basically completed the sinicization, these military towns and the people of the military towns established by the Tuoba heirs were naturally incompatible with the mainstream of the tribe, because the process of Sinicization in the northern border was obviously slow, so the contradiction between the Xianbei Tuoba people in the military town and the Xianbei Tuoba people in the interior would be highlighted, and these military towns would become the internal time bomb of the Northern Wei Dynasty. The slightest political change in the Northern Wei Dynasty would cause dissatisfaction among the military towns, which in turn would lead to the disaster of the Northern Wei Dynasty.

In fact, after the Sinicization reform of Emperor Xiaowen of the Northern Wei Dynasty, because the capital of the Northern Wei Dynasty was moved to Luoyang from Pingcheng, which is today's Datong, Shanxi, the people of the military town were extremely dissatisfied with the Northern Wei Dynasty, because of the internal relocation of the capital, it was difficult for the people of the military town to be valued by the rulers of the Northern Wei Dynasty. The people of the military town began to rebel under the leadership of the Xiongnu monk who broke the six Han Baling, known as the Six Towns Uprising, although the Six Towns Uprising soon failed, but because the rebel army in the process of turning to the war, a large number of military towns were left in Hebei, and soon, these military town people and the people of Hebei rose up again, known as the Hebei Uprising, in the Hebei Uprising, Yuwentai and Gao Huan, who were born in the military town, occupied the Guanzhong region and the Kanto region respectively, and each supported the Northern Wei Dynasty clan as the puppet emperor, The establishment of the Western Wei Dynasty and the Eastern Wei Dynasty, the Northern Wei Dynasty also existed in name only, and then the sons of Yuwentai and Gao Huan replaced the Western Wei Dynasty and the Eastern Wei Dynasty respectively, and established the Northern Zhou Dynasty and the Northern Qi Dynasty.

The Northern Wei Dynasty laid the foundation for the unification of the north because of the military town, and at the same time perished because of the military town, which is the sorrow after the culturally backward nomads established their power in the great integration of nationalities. None of the regimes in the extinct Sixteen Kingdoms that we mentioned before could not have problems after the main tribes were basically sinicized. Therefore, after the Northern Wei Dynasty began to govern from Tuoba Hei, it began to advocate sinicization on a large scale, and it was dying out step by step. On the other hand, the newly established Liu Song Dynasty became strong under the leadership of Liu Yu and his successor ruler Liu Yilong, which of course has a lot to do with the fact that the rulers of the Liu Song Dynasty came from the Hanmen Shu people, but the Liu Song Dynasty was only an attempt by the Shu landlord class to become the ruling class, or a transitional period, the power of the family within the Liu Song Dynasty was still strong, in any case, the strength of the Liu Song Dynasty made the people see the superiority of the Hanmen children, This also laid a good foundation for the later Shu landlord class to become the ruling class of feudal society.

With the beginning of the Southern Dynasties, the Liu Song Dynasty was busy with the governance of the Jiangnan region, and its influence on the regime established by the nomads in the north gradually weakened. Also under the careful governance of the Tuoba heir, the Northern Wei Dynasty that occupied the Kwantung region became the most powerful dynasty in the northern land, and at this time, the Xianbei Tuoba Department was still between the nomadic lifestyle and the settled lifestyle, so the Northern Wei Dynasty could completely attack the regime established by any nomadic people who entered the northern region before the Xianbei Tuoba Department in military terms, so the Northern Yan regime and the Huxia regime adjacent to the Northern Wei Dynasty were the first to be coveted by the rulers of the Northern Wei Dynasty, so it depends on these two regimes, Which one came first to show the scene of decline.
