The Zen Temple Alliance appeared in the Northern Song Dynasty. This is an agreement reached between the Northern Song Dynasty and Liao State after twenty-five years of war. At that time, Liao soldiers invaded the Northern Song Dynasty southward, constantly harassing the border of the Northern Song Dynasty, and then the Northern Song Dynasty changed from active attack to passive defense. At this time, Liao Shengzong led his troops into the territory of the Northern Song Dynasty and captured the observation history of Yunzhou in the Northern Song Dynasty. Song Zhenzong knew and fled to the south. At that time, the Prime Minister suggested that Song Zhenzong continue northward to boost morale, and shot and killed the Liao army leader in Aizhou. This incident dealt a great blow to the morale of the Liao army. At this time, the Liao army was caught in a dilemma. Because the war lasted too long, their food supply was insufficient. Even if they are relatively successful in this war, they can't persist without food supply. If the Liao army is defeated by the Northern Song Dynasty in this war, their losses will be immeasurable.
Finally, under the consideration of Emperor Shengzong of Liao and Xiao Taihou, they wanted to make peace with Song Jun, which was also the intention of the Northern Song Dynasty at this time. Later, the Liao army sent the captured hostages to Ganzhou to show its determination to make peace. Because both sides have the determination to make peace, the single-source alliance was successfully signed soon. In 65438 BC +0005 65438+ 10, Song and Liao countries formally signed the alliance of single sources. Under the constraint of the single-source alliance, the peace between Song and Liao countries lasted for more than a hundred years.
The meaning of the Zen House Alliance is equivalent to peace bought with money. After that, Song and Liao countries also established mutual trade markets in the border areas.
