In 208, after Cao Cao unified the north, he went south by Liu Biao's death, and his son Liu Cong surrendered to Cao Cao. Liu Bei left Xinye and went south to Jiangling. On the way, Cao Jun overtook him and fled to Xiakou.
At this time, Lu Su went to the preparation office to inquire about the situation, and Liu Bei also sent Zhuge Liang to Jiangdong. The two sides formed an alliance to resist Cao Jun, and Sun Liu's allied troops defeated him in Chibi with fewer soldiers. After Cao Jun returned to the north, he pacified the allied forces of Ma Chao and northwest Han Sui and unified the north. Promote the formation of three pillars.
Sun Quan and Liu Bei also began to compete for Jingzhou. Liu Bei successfully forced the four counties in Jingnan; Sun Quan's Ministry will also send troops to South County of Jingzhou, and successfully take the northwest region as its own.
2 1 1 year, Liu Bei led his troops into Yizhou and gradually occupied the original territory of Liu Zhang. In 2 19, Liu Bei seized Hanzhong from Cao Jun, and Guan Yu also launched an attack on Cao Jun, but Sun Quan sent Monroe to attack and kill Guan Yu, occupying most of Jingzhou and fighting the Han army across the Three Gorges.
In 222, Zhang Fei was killed, and Liu Bei sent troops to fight Wu Jun in Yiling. In the First World War, Xiao Ting was defeated by Lu Xun, the general of the State of Wu, and returned to Yizhou. Liu Bei died in Baidicheng soon.
Soon, with the efforts of Zhuge Liang and Sun Quan, Shu Han and Dongwu resumed their alliance and jointly resisted Cao Wei. At this point, the tripartite confrontation between the three countries was formally formed.
2, the influence of the three pillars:
The tripartite confrontation between the three countries promotes national division and hinders national reunification, so it has a negative impact in the process of historical development. If we must say that it has a positive effect, it is a confrontational situation in which the three countries are evenly matched and contain each other. During this period, mutual confrontation brought short-term peace and short-term economic development. In a big way, division has always hindered the process of historical development.
In the first year of Yankang (220), Cao Pi proclaimed himself emperor. Because of his surname Cao, he was later called Cao Wei or Cao Wei regime, and his capital was Luoyang. In the second year of Xianxi (265), Cao Huanchan was located in Sima Yan and enjoyed the country for 46 years. He mainly controlled Kyushu in the north (north of the Yangtze River) and had the most powerful influence.
In the first year of Zhangwu (22 1), Liu Bei proclaimed himself emperor. In order to show the legitimacy of its regime, the country name is still Han. Because the area it controlled was Yizhou (Shu), it was later called Shu Han or Shu for short.
Shu Han is the weakest. In the first year of Yan Xing (263), Liu Chan surrendered to Wargo and enjoyed the country for 43 years. In the first year of Jianxing (229), Sun Quan officially proclaimed himself emperor, and established the political title of Wu. Because his surname is Sun, he is called Sun Wu, and because he controls Yangzhou, Jiaozhou and Jingzhou, he is also called Sun Wu.
Si Mazhao died in 265, and his son Sima Yan seized the Cao Wei regime, made Luoyang its capital, and established the Jin Dynasty, known as the Western Jin Dynasty in history. After he proclaimed himself emperor, he began to prepare for cutting Wu, and sent him to build ships in Yizhou, with Yang Hucheng guarding Xiangyang and Wu Kangshou Jiangling. After Sun Hao ascended the throne in 264, Jiaozhou (now Guangxi Province and northern Vietnam) surrendered to Cao Wei. Two years later, Wu Jun tried to take it back, but was defeated by Jin general Mao Huan.
In 269, Sun Hao joined forces with Yu Yun, Tao Huang, Xu Li and others in Hepu, and it was not until 27 1 that Jiaozhou was recovered. In 279, Yun Xiu's subordinate Ma rebelled in Guangzhou (now Guangdong and Guangxi), and Sun Hao sent Teng Xun, Tao Jun and Tao Huang to encircle and pacify it. In the same year, the Jin army led the army south, and the state of Wu was in jeopardy.
After the death of Lu Kaihe, an important official, Jin proposed that Yang Hucheng attack Wu, but Jia Chong opposed it and gave up. In 279 AD, when the northwest rebellion began, Du Yu wrote that it was time to attack Wu, while Jia Chong and Xun Yu opposed it on the grounds that the northwest was undecided. Finally, Sima Yan decided to attack Wu on a large scale in that year 1 1 month, which was the famous battle of Jin and Wu.
He took Jia Chong as the viceroy, with Wang Zhuo and Tang Binjun in the upper reaches, Wang Rongjun in the middle reaches and Wang Hun and Sima Zhoujun in the lower reaches. In 280 1 month, Sun Hao was appointed as the prime minister, and led Ku Lokshin and Sun Zhen to cross the river to resist Wang Hunjun, but they were all defeated and died.
Wang Zhuo's army cooperated with other Jin Jun along the Yangtze River and captured Xiling, Jiangling, Wuchang and Xunyang. Du Yu also captured the south of Jingzhou. On March 15, Sun Hao saw that 8 Jin Army had surrounded Jianye. He thought that the tide was over and surrendered. Sun Wu perished, and the Western Jin Dynasty unified the world, thus ending the Three Kingdoms period.
