The alliance of single source was an agreement reached between the Northern Song Dynasty regime and Liao State in the battle of single source, because the two sides were tied. As a result, the single-source alliance maintained the peace of the Song and Liao Dynasties for a hundred years, but it also cost the Song Dynasty tens of millions of dollars.
Some people say that it is cost-effective to spend hundreds of thousands a year in the Song Dynasty, because it is a hundred years of peace, but don't forget that real peace doesn't come like this.
Because, since then, the Song Dynasty has been fantasizing about exchanging money for peace. After the demise of Liao, the old coins were given to Jin. When soldiers of the state of Jin besieged the capital of song dynasty, the Song government plundered the wealth and women of the whole city in exchange for imaginary peace. As a result, Xu Jin demanded too much, taking advantage of the Song government's fantasy that huge wealth could be exchanged for Guo Xu's opportunity to withdraw. He defeated Song Jun in the capital of song dynasty and captured Qin Hui, the second emperor of song dynasty. This is the famous shame of Jingkang in the history of our country, saying that others can't beat it, but the Song Dynasty didn't want to.
Then, why is it good to give old coins to Liao countries and bad to give old coins to Jin countries? There is a simple reason. The so-called exchange of old coins for peace is only a superficial phenomenon.
The first prerequisite for truly maintaining peace in the Song and Liao Dynasties is the considerable military strength in the Song Dynasty. The premise of the alliance is that the Liao army suffered setbacks on the battlefield and knew that it could not defeat the Song Dynasty.
Instead, he took advantage of the weakness of the emperor of the Song Dynasty, made a fortune by taking advantage of his weakness, and took hundreds of thousands of ancient coins for nothing.
To tell the truth, compared with the strength of the Song and Liao Dynasties at that time, the Song Dynasty could repel the Liao Army if it worked harder.
The second factor to maintain bilateral peace between Song and Liao is the large-scale trade between Song and Liao. Compared with the Song Dynasty, Liao, as a developing country, met a developed country, so it hoped to maintain trade with the Song Dynasty and obtain tight materials. Because the border trade was opened in the Song Dynasty, Liao countries did not need to plunder from the south, and they could obtain the needed goods through legal trade. This is just like the reduction of wars after Mongolia and the Ming Dynasty opened their borders.
The new year's coin shows that the weakness of the Song Dynasty has nothing to do with peace. Therefore, even giving Liao a penny is a waste.
After the establishment of the Southern Song Dynasty, Jin and Song maintained overall peace. This is not because the song dynasty gave more money, but because of the song army! As we all know, the Northern Song Dynasty gave the lucky money to the Jin State, but it was destroyed by the Jin State. In the Southern Song Dynasty, the money given to the State of Jin provided a relatively peaceful environment. This is because, compared with the unreliability of Qin Hui in the Northern Song Dynasty, the Emperor Gaozong in the Southern Song Dynasty is actually a little reliable, so there are some generals who can fight, such as Yue Fei, Han Shizhong and Wu Jie.
Only when they defeated Xu Jin's invasion on the main battlefield did the Southern Song Dynasty enjoy peace.
Unfortunately, Song Gaozong's self-destruction of the Great Wall killed Yue Fei, which not only lost the great opportunity for the Northern Expedition to recapture the lost land, but also chilled the hearts of countless soldiers who fought against the Jin Dynasty, resulting in the Southern Song Dynasty only surviving.
This is my bloody Song Dynasty, a dynasty good at self-castration.
In fact, in addition to the tens of millions of coins accumulated in the past 100 years, there is still 80% military expenditure. As we all know, the Song Dynasty was the most militaristic dynasty in Chinese history. Because, although the military was weak in the Song Dynasty, he spent most of his finance on the army, sometimes even reaching 80% of his fiscal revenue.
According to Zhang Ziquan's book (volume 13) and Differentiating Differences, the cost of raising soldiers is 78% of the world's total.
This is a phenomenon that has never happened in peacetime in any previous dynasty.
Therefore, the Song Dynasty was a militaristic dynasty.
