If you want to ask which of the many feudal states in the Western Jin Dynasty has the most exaggerated composition? Chengdu is definitely on the list. The initial size of the state of Chengdu was based on the kingdom of Shu County, Guanghan County, Qianwei, and Wenshan 100,000 households, and Shu County's Taishou even became the internal history of Chengdu. Among them, Shu County, Qianwei, and Wenshan belonged to the Western Jin Dynasty, and Guanghan belonged to Liang Prefecture.
The first king of Chengdu, Sima Ying. To get sima yan's favor so much, the only one who could seal the country was his stupid white and sweet son Sima Ying. Sima Ying, Zi Zhangdu, sima Yan's sixteenth son, mother cheng cairen. In November of the tenth year of Taikang (289 AD), Sima Ying was crowned king of Chengdu, a superpower with 100,000 households, but Sima Ying never went to his own fiefdom. On the contrary, his base camp has always been in Yecheng, and it is here that he is very busy during the Rebellion of the Eight Kings. In the first year of Yongxing (304 AD), the 26-year-old Sima Ying came to the peak of power and became the emperor's brother-in-law, and his chengdu state was also added to the twenty counties.
However, as Wang Jun took the Xianbei people, Wuhuan people and Sima Ying to fight, Sima Ying suddenly had nothing, and after Sima Ying's downfall, Sima Ying turned around a large circle and eventually became a prisoner of Sima Ying, the king of Fanyang. Although Sima Yu wanted to save his life, with Sima Xiao's sudden and violent death, Sima Ying was eventually killed by Liu Youjiao, at the age of twenty-eight.
The last king of Chengdu, Sima Zun. After Sima Chi ascended the throne, he thought of this brother and did not want him to die, but his two sons had all been killed together, so he found Sima Rui, the king of Donglai, to succeed Sima Ying, but his title was the king of Huarong County. Later, Sima Zun became the king of Chengdu again, but at this time, Yizhou was already the territory of the State of Cheng, so Sima Chi divided Huarong County, Zhouling County, Jianli County, and Fengdu County into four counties, and became the new Chengdu State. From the four counties to only four counties left, there are indeed few ups and downs like the Chengdu State.
Sima Zun's ending history book does not specify, but it is likely that he was doomed in a series of chaos in the fifth year of Yongjia (311 AD), and the state of Chengdu became history.
