In 1127, the Jin state destroyed the Liao state and then launched an offensive against the Northern Song dynasty in the north. However, although the Jin state's war offensive against the Southern Song Dynasty lasted for a considerable time, it ignored the Western Liao. There are many factors behind this.
The Jin State's continuous war offensive against the Southern Song Dynasty was mainly due to the fact that the Southern Song Dynasty was regarded as a transitional state between the north and the south, and its demise was of great significance to the Jin State's unification of the Central Plains.
As a large country in the south, the Southern Song Dynasty had a lot of land and resources that made the Jin State red-eyed. Therefore, the Jin State attacked the Southern Song Dynasty with the strength of the north, in an attempt to destroy the southern dynasty that was still standing.
However, when the Jin State sent troops to the Southern Song Dynasty, why did it ignore the Western Liao? The reasons for this are as follows: First, the Jin State was extremely exhausted after destroying the Liao State and the Northern Song Dynasty. The war in the north lasted for a long time, which consumed a lot of manpower, material and financial resources of the Jin State, and greatly weakened the strength of the Jin State.
In the face of the resistance of the Southern Song Dynasty, although the Jin State was walking on thin ice, it still insisted on going its own way. Attacking Western Liao, on the other hand, required the consumption of more troops and resources, and the Jin State no longer had enough capacity to face two powerful enemies at the same time.
There was no direct territorial dispute or economic competition between the Western Liao and the Jin state. Western Liao was located on the northwestern border, and the area bordering the Jin state had limited resources, and the Jin state had no clear motive to wage war against it.
In addition, Western Liao was geographically distant from the Jin State, and the Jin State's conquest of the Western Liao required crossing a complex geographical environment, which was a formidable challenge for the Jin State.
The Jin State had a moderate policy towards Western Liao. Although the Jin State did not directly launch an attack on Western Liao, a certain degree of peace and cooperation was maintained between the two sides. Jin and Western Liao were both successor states after the collapse of the Liao State, and they had certain historical origins and contacts with each other. Through diplomatic means, the Jin State maintained a relatively friendly relationship with the Western Liao, avoiding unnecessary conflicts and frictions.
In addition, the country needs to consider the attitudes of other countries and the response to the country's strategy. The Western Xia had a certain connection with the Western Liao, and the Western Xia was also a potential threat to the Jin State.
If the Jin State sent troops against Western Liao at the same time, it might trigger Western Xia vigilance and counterattack, making Western Xia a threat to its southern front. As a result, the Jin chose to remain cautious about Western Liao and focus more on the Southern Song Dynasty.
The reason why the Jin State ignored the Western Liao was due to the fact that the Jin State was exhausted, had no clear motives for the Western Liao, had a certain peace policy and friendly relations, and needed to consider the attitudes of other countries. Although the Jin State adopted the strategy of attacking the Southern Song Dynasty.
