What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
In Chinese history, there have been two "Southern Song Dynasties", one is the Southern Dynasty Song established by Liu Yu during the Southern and Northern Dynasties, and the other is the Southern Song Dynasty established by Zhao Shi, according to the legal system, these two dynasties are the orthodox dynasties in Chinese history, and they are also divided in the southern region, and the north also has the political power established by ethnic minorities, so since the national name is "Song", which of the Southern Dynasty Song and the Southern Song Dynasty is more powerful? Netizens have said: who is weak and who is embarrassed!

Since we want to compare the strength and weakness of these two dynasties, then we will first compare from the founding monarchs of the two dynasties, the founder of the Southern Dynasty Song Dynasty is Liu Yu, Liu Yuzu is also broad, the descendants of Liu Jiao, the fourth brother of Liu Bang, the king of ChuYuan, but four or five hundred years have passed, Liu Yu can only be regarded as a small cold disciple, in the Eastern Jin Dynasty, which implements the Nine Pins Zhongzheng system, Liu Yu can only go to the army if he wants to have a career, and it just so happens that Xie An is training a new army in Jingkou, so Liu Yu joined it.
It was also in the army's career that Liu Yu repeatedly made military achievements, and eventually became the one who achieved the Eastern Jin Dynasty, he reigned for a short time, but he began to break the monopoly of the scholar clan, reuse the han disciples, implement the Yixi reform, and strengthen his strength, which also enabled the later Song Wen Emperor to take the throne, he was able to develop the national strength very well.
And the founder of the Southern Song Dynasty, Zhao Shuo, himself was the son of Emperor Huizong of Song, at the time of the change of Jing Kang, he was the Great Marshal of the Terracotta Army, with 400,000 troops but did not dare to save Beijing, watching The capital was plundered, after the change of Jing Kang, he quickly ascended the throne and began the road of fleeing south, if it were not for Yue Fei, Han Shizhong and other four generals of Zhongxing, whether the Southern Song Dynasty could be established was still a problem.
Therefore, from the point of view of the founding king, the complete Yan structure is far inferior to Liu Yu.
The second is the comparison of military strength, let's first talk about the Southern Song Dynasty, to tell the truth, when the four generals of the Southern Song Dynasty were still alive, the military strength was still very good, even the Jin people in the north were beaten by Yue Fei, but in the end, Yue Fei was killed, Han Shizhong and others were also stripped of military power, and the military strength of the Southern Song Dynasty also declined, so later Song Xiaozong's three Northern Expeditions were fruitless.
At this point, the Southern Dynasty Song and the Southern Song Dynasty were actually similar, when Liu Yu and Tan Daoji and others were still there, the military strength of the Southern Dynasty Song was also very strong, especially Liu Yu recovered Shu land, destroyed Southern Yan, Later Qin, and defeated Northern Wei, which can be described as an invincible hand all over the world, and later after Liu Yu's death, there was also a famous general Tan Daoji, but later Emperor Wen of Song destroyed the Great Wall and killed Tan Daoji, and as a result, when the Northern Expedition was later, not only was it defeated but also counterattacked.
Therefore, in terms of military strength, these two dynasties should be similar, both of which are strong in the early stage and weak in the late stage.
Finally, in terms of territorial territory, the Southern Dynasty and song dynasty had nearly 3 million square kilometers of land in their heyday, Liu Yu first recovered Shu land, and later destroyed Southern Yan and Later Qin, and the rough territory was the south bank of the Yellow River, including Guanzhong, of which Chang'an and Luoyang were in the northwest, and the eastern part occupied the Shandong Peninsula.
The territory of the Southern Song Dynasty in its heyday was more than 2 million square kilometers, which was not so much at the beginning, and later after Zhao Zhao made peace, the territory was roughly fixed in the Qinling Huai River area, so in terms of territory, the Southern Song Dynasty was also stronger than the Southern Song Dynasty.
Therefore, from a personal point of view, although the times are different and the way of comparison is different, in general, the Southern Dynasty and the Song Dynasty are stronger than the Southern Song Dynasty!
