Political History  

In 189 when Emperor Ling of the Eastern Han dynasty died, a young emperor - Emperor Shao was put on the throne. Resenting the manipulation of eunuchs, two generals Yuan Shao and He Jin plotted to murder them. During the chaos caused by the fighting between the eunuchs and generals, Dong Zhuo, a treacherous court official of the Eastern Han drove his army into Luoyang. With full political power in his hand, Dong Zhuo dethroned Emperor Shao and put Emperor Xian on the throne. All Dong's deeds aroused strong protest from the courtiers and many local officials. As the political situation became acute, a large-scale civil war finally broke out.

After Dong Zhuo invaded Luoyang, Cao Cao fled to Chenliu (currently southeast of Kaifeng in Henan Province) and began to assemble military forces to revolt. In 193, Dong was killed in a mutiny but the melee remained. This period of unrest continued until 196, Balkanized areas were formed among which the most two powerful ones were those of Yuan Shao and Cao Cao.

In 196, Cao Cao held Emperor Xian under duress and took this advantage to strengthen his military power. In 201, with comparatively weaker strength, Cao Cao defeated Yuan Shao in the Battle of Guandu after which he gradually unified the northern area of China. In 209, Cao Cao drove his troops to the southern area and captured Jingzhou. But when he wanted to expand his power further to the south, he was defeated by the allied forces of Liu Bei and Sun Quan in the Battle of Red Cliff and thus he withdrew his army back to the central plains of China.

In 220 when Cao Cao died, his eldest son Cao Pi proclaimed himself emperor, with Wei as his National Title and Luoyang as his capital city. In 221, Liu Bei proclaimed himself emperor, with Shu his national title and Chengdu the capital city. And in 229, Sun Quan proclaimed himself emperor in Wuchang (currently Wuhan), and later moved the capital to Jiankang (currently Nanjing), with the national title Wu. Since then, the so-called Three Kingdoms' Tripartite Confrontation was formed. On the whole, Wei occupied the north, Shu occupied the southwest and Wu occupied the southeast.

Upon the founding of the three kingdoms, rulers of each kingdom all committed to improve the way of ruling and develop their national economy. In the Kingdom of Wei, Cao Cao made many reforms to discard old policies inform previous dynasties. The Tun Tian (farming done by soldiers) System was also carried out, which greatly promoted the national productivity. In the Kingdom of Shu, Zhuge Liang set up strict social order and tried to govern the kingdom by law. With his assistance, Shu's agriculture and handicraft industry developed rapidly. Additionally, Shu formed a friendly relationship with ethnic minorities in southwestern areas. In the Kingdom of Wu, the shipbuilding industry was much more prosperous. As for the national strength, the Kingdom of Wei ranked first, Wu second and Shu third.

Throughout the Three Kingdoms Period, battles between the three countries were countless. Among those, battles between Shu and Wu fighting for Jingzhou, Shu and Wei fighting for Hanzhong as well as Wei defeating Shu were all illustrious ones in Chinese history.

Finally, the end of the Three Kingdoms Period started from the Sima Yan (son of Sima Yi and chancellor of Wei)'s usurpation of Wei and the establishment of the Jin Dynasty (265 - 420). In 282 when the Jin army conquered the last kingdom - Wu's capital, the Three Kingdoms Period was ended.
