Jiang Qi was the founding vassal state of the Western Zhou Dynasty, and Zhou Wuwang personally awarded the title of vassal state. The first monarch was Jiang Taigong Lu Shang, a strategist of the Zhou Dynasty, whose title was Marquis. Qi was officially conferred by Zhou Guo, and together with Yan, Jin, Qin and Chu, it was several major vassal states of Zhou Guo. During the Spring and Autumn Period, the Duke of Qi was strong and took the lead in fighting? Respect the king and oppose the foreign countries? Banner, for the emperor to levy four directions to cut princes, Qi thus became one of the five tyrants in the Spring and Autumn Period, and its actual power was greater than that of Zhou. In the era of Qi Henggong, Chen Wan, the son of Chen Guo, fled to Qi State and was treated by Qi Henggong. Later generations Chen Wan changed his surname to Tian and gradually took control of Qi.
In 545 BC, Tian Wan, the fourth grandson of the Duke of Chen, joined forces with Bao, Luan and Gao to wipe out the Qing nationality of Qi. Later, Tian and Bao destroyed Luan and Senior Two. Tian won the support of Qi Huangong and Chinese people for "the sons and gongsun have no money to share the city privately" and for Chinese people, "poor people are lonely, private people are depressed". Qi Jinggong's office is corrupt. Tian's son, Tian Beggar, borrowed a lot and paid back a little, which made "Qi people return to the water" and increased his hukou and strength. It means "the public abandoned their people and went home." In 489 BC, Qi Jinggong died, and Qi Huangong, Gao Er's, established Gongzi Tea, Tian Ji and Gao Er's, and established another Gongzi Yang Sheng to stand on his own feet. Since then, I have mastered the state affairs of Qi.
In 39 1 year BC, Sun Tian and Qi Kanggong of Tian Chengzi IV were abolished. In 386 BC, Tian He exiled Qi Kanggong to the sea and established himself as a monarch. In the same year, he was named the Duke of Qi and the King of Zhou An. In 379 BC, Duke Kang of Qi died, and the surname of Jiang Qi died. Tian Jia still takes "Qi" as the title, which is called "Tian Qi" in history. Tianqi state owned the imperial edict of the Zhou royal family, which was strongly supported by the nobles and civilians of Qi State, so Tianqi was also orthodox. Sima Qian recorded the history with his family and family.
The State of Jin was divided among three families, namely North Korea, Zhao and Wei San, and all three families were made monarchs by Zhou Wei. Therefore, Korea, Zhao and Wei were the legitimate vassal states of the Zhou Dynasty. The prince usurped the throne and forced him to give him the throne, calling himself the prince. However, the son was not recognized by the decree and the people of Yan, and eventually died, so the son became the prince of Yan and was not regarded as orthodox.
