The Jin State destroyed the Liao State and the Northern Song Dynasty in one fell swoop, swept the north, and the general trend was like a rainbow, but when the Northern War was initially decided, the Jin State fell into a southern dilemma that seemed to be easy, but could not be broken through.
The successor of the Southern Song Dynasty and the Northern Song Dynasty, it has a prosperous water town in the south of the Yangtze River. With a strong city, a well-developed economy, and a strong navy, they were a threat to the Jin State, which faced various challenges if it wanted to continue its march south, despite its victory in the north.
The Southern Song used a skillful balancing act in diplomacy, and they established alliances with northern powers such as the Western Xia and the Mongols, making it impossible for the Jin to break through to the south in one fell swoop. The Southern Song Dynasty defused the threat of the Jin State through diplomatic means, so that it was in a relatively safe state.
The Southern Song Dynasty is good at using geographical advantages, the geographical environment of the water towns in the south of the Yangtze River is very unfavorable for large-scale attacks, the water network is staggered, and the rivers are vertical and horizontal, making it difficult for the cavalry of the Jin State to give full play to their advantages, not to mention the large-scale army, the Southern Song Dynasty people have a natural advantage in the water army, and can quickly maneuver in the area where the rivers are crisscrossed, and the construction of fortresses is also more convenient.
After the Jin State destroyed the Liao State and the Northern Song Dynasty in the north, when facing the south, it found that the rule of the Southern Song Dynasty was relatively stable, and the people lived a rich and stable life, without causing large-scale civil strife and rebellion. This made it difficult for the Jin State to weaken the Southern Song Dynasty through civil strife, and could only choose to negotiate with it.
In the attempt to go south again and again, the Jin State found that in the face of various difficulties in the Southern Song Dynasty, it finally had to choose to solve the problem through peaceful means, and the Southern Song Dynasty and the Jin State signed many peace agreements, so that the two countries maintained a relatively stable situation for a period of time, and the Jin State obtained some wealth and territory of the Southern Song Dynasty through this peaceful means, but the Southern Song Dynasty was not destroyed.
The outcome of this historical event not only reflects the Southern Song Dynasty's good diplomatic strategy and flexible use of geographical advantages, but also shows that the Jin State was faced with the difficulties of the South, the Southern Song Dynasty was able to maintain its independent status, and the Jin State was unable to completely annex the Southern Song Dynasty for various reasons, leaving a watershed in this history.
