Why did it take 23 years for the Mongols to destroy the Jin, 21 years to destroy the Western Xia, bu

Because at that time, the Southern Song Dynasty was in a safe corner and there was a moat of the Yangtze River, which was difficult for them to cross, so it was not so easy to destroy the Southern Song Dynasty.

Although the Southern Song Dynasty could not attack, it was very good to defend the city, and it was necessary to gather the strength of the whole country to defend Xiangyang City, which was easy to defend and difficult to attack, so as to delay the Mongol Empire for decades.

Liao 916-1125 Jin united with the Northern Song Dynasty to destroy Liao.

<> "During the Song-Jin Confrontation, Why Didn't Jin Destroy Western Xia?"

During his lifetime, Emperor Injong Li In-hyo devoted his life to stabilizing the power of Western Xia, and by maintaining friendly relations with the Jin State and the Southern Song Dynasty, he realized a dual foreign policy of "attaching Jin and Song". As the emperor of Western Xia, he was well aware of the strength of the Jin state, so he chose to maintain close ties with the Jin state, and consolidated his dominance by eliminating internal political enemies by uniting with the Jin state. The friendly relations with the Southern Song Dynasty also brought a set of economic and cultural exchanges to the Western Xia, and enhanced the national strength of the Western Xia.

However, Renzong did not abandon his ambitions for expansion into Western Xia territory. During his reign, he launched several military campaigns against the Southern Song Dynasty in an attempt to seize the land of the Southern Song Dynasty. However, due to the great power of the Southern Song Dynasty and Renzong's desire to maintain a state of peaceful competition with the Southern Song Dynasty, these military operations did not achieve much success.

Renzong understood that starting a war with the Southern Song Dynasty would not only sacrifice a lot of manpower and material resources, but would also destroy friendly relations with the Southern Song Dynasty, which was not in his own long-term interests.

At the same time, Renzong also carried out a series of internal reforms. He adopted a policy of inclusiveness and sinicization, which allowed the Han people to gain a certain status in Western Xia society. He attached great importance to education, advocated cultural development, built a large number of temples and colleges, and cultivated many outstanding cultural talents.

His focus on agricultural production and commercial development contributed to the economic prosperity of Western Xia. It can be said that the reign of Renzong enabled the Western Xia to reach a stage of relative stability and prosperity under his leadership.

His foreign policy and domestic reforms have demonstrated his wisdom and strategy. However, due to the changes in the current situation and the constraints of the external environment, he did not achieve the conquest of the Southern Song Dynasty and the independence of the Jin State. Despite this, Renzong's place in the history of the Tangut was still very prominent, and he was recognized as one of the wisest and wisest emperors in the history of the Tangut.

The three masters of the Ming Dynasty are juxtaposed, the birth of the new Three Kingdoms is juxtaposed, and the peaceful competition is the mainstay, and the destruction of the country is the "three masters". Kim Sejong was known as "Little Yao Shun". Zhao Yi said that the nine monarchs of the Jin Dynasty were the most virtuous in Sejong.

Jin Shizong was more sinicized, and the previous generations of gold lords were more in line with the traditional Confucian view of rule, and Han scholars of previous dynasties also spoke highly of him. For Xia Renzong, he is also a sympathetic person. Song Xiaozong was bent on restoring the Central Plains and making great efforts to govern the country, and his reign was known as "the rule of Qianchun".

Later generations called him "Zhuo Ran the head of the emperors of Nandu". During the reign of Emperor Renzong of the Western Xia, he paid attention to cultural development, such as imperial examinations, the establishment of laws, the promotion of religion, and the suppression of corruption, all of which made it the most extensive period of the Western Xia region. As a result, during the more than 20 years of coexistence of the three rulers of the three countries, the three kingdoms mainly developed their economies, and staged many intelligence stations and currency wars between the three countries.

That is, to see who has the strongest ability to govern the country and which country has the strongest development. However, during the reign of Xia Renzong, his clan power was not well controlled by Zhixiao. As a result, his son was killed, and the clan usurped the lack of manuscript positions, and directly abandoned the policy of "attaching Jin and Song" that had been pursued, which led to a series of wars with the Jin State, which brought convenience to the Mongol forces to destroy Xia and Jin.

Because the Mongols united with the Southern Song Dynasty, they perished, fell, Western Xia and Jin dynasties.

Because at that time, the Western Xia and Jin dynasties were closest to Mongolia, and the two countries were seriously weakened. The Southern Song Dynasty was fought for several decades because the Mongols carried out the second and third western expeditions while fighting the Southern Song Dynasty, and the troops could not keep up. It consumed a lot of troops to fight Europe, and it consumed a lot of troops in its own civil war.
