Northern Han immigrated to Zhao Kuangyin.

Among the Five Dynasties and Ten Kingdoms, two regimes were the weakest, one was Jingnan, which occupied Jiangling, and the other was Northern Han, which was divided up in the north-central part of Shanxi. In order to destroy the Northern Han regime, Chai Rong and Zhao Kuangyin successively made personal expedition, but both failed. This small country has existed for 28 years and became the last of the ten countries to perish. So, how did the weak Northern Han resist the powerful Later Zhou Dynasty and the Northern Song Dynasty?

In 95 1 year, Guo Wei, a general of the later Han Dynasty, proclaimed himself emperor and established the regime of the later Zhou Dynasty. When the news reached Taiyuan, Liu Chong, the governor of Hedong, was very angry, because he was the younger brother of Liu Zhiyuan, the emperor of the later Han Dynasty, and now his country has been taken away. How can he swallow this tone? It happened that at this time, Liu Chong's son liuyong was killed by Guo Wei. Ethnic hatred combined with family hatred, so Liu Chong proclaimed himself emperor in Taiyuan, continuing the title of Han Dynasty, which was called Northern Han in history.

The territory of the Northern Han Dynasty is very small, with only 13 states and only 35,200 households, and only 30,000 to 40,000 troops can be mobilized nationwide. But the enemy of the Northern Han Dynasty, that is, the Later Zhou Dynasty, was very powerful. In order to cope with the latter Zhou Dynasty, Liu Chong had to look for foreign aid, and he turned his attention to the north. Liu Chong "asked for help from Qidan with a large sum of money, but he still asked his nephew to do things." At that time, the emperor of Liao was Ruan, 22 years younger than Liu Chong.

With the support of "michel platini", Liu Chong immediately gained confidence and fought against the Zhou Dynasty. However, repeated defeats and wars failed to open the situation. In 954, Guo Wei died, and Liu Chong was overjoyed when he heard the news. He immediately mobilized 30,000 troops and asked Liao to send 50,000 troops to attack the Zhou Dynasty. Liu Chong didn't expect Chai Rong, the new emperor of the Zhou Dynasty, to be worse than Guo Wei. In the Battle of Gaoping, the Northern Han Army was defeated, and Liu Chong only led hundreds of cavalry to flee hastily.

Chai Rong took the opportunity to lead the army northward, reaching Taiyuan at the gates and being besieged for more than two months. Liu Chong is about to give in. At this time, "michel platini" pushed. Shi Chao, the general of the Zhou Dynasty, was defeated by the Liao army at Shilingguan, and Chai Rong had to retreat. Liu Chong became ill because of anxiety and anger, and died soon. His son Liu Jun succeeded to the throne. As soon as Liu Jun came to power, he addressed Liu Jun as a "public" to Yelv of Liao Muzong, and Yelv addressed Liu Jun as a "child emperor".

In 960, he proclaimed himself emperor, and the envoy of the later Zhou Dynasty set out to join the Northern Han Dynasty. Liu Jun thought it was a golden opportunity, so he led 30,000 troops to help him. As a result, Zhao Kuangyin personally expedition, quickly put down the rebellion, and the Northern Han lost the army, but did not benefit. Since then, Zhao Kuangyin has adopted a unified policy of "south before north, easy before difficult", so there is no war against the Northern Han Dynasty, and there is no large-scale war between the two sides.

In 968, Liu Jun died of illness, and the political situation in Northern Han Dynasty was turbulent. Liu, who succeeded to the throne, was killed and Liu Jiyuan succeeded. When Zhao Kuangyin heard the news, he decided to solve the Northern Han Dynasty first, so he led an army to the Northern Expedition in 969. Zhao Kuangyin played well this time, repelling the reinforcements from Liao country first, and then leading Fenhe River to irrigate Jinyang City. The flood even broke through Cheng Nan and poured into the city. When Song Jun was about to rush into the city, a pile of firewood drifted to the gap of the city and blocked the gap. The northern Han army took the opportunity to block the gap.
