In addition to Wei, Shu, and Wu, the only people who can be called separatist regimes are generally the Gongsun family of Liaodong Province, the Shijia of Jiaozhou, and song Jian of Fenghan, and the regimes established by the three of them all existed for at least thirty years, which was quite difficult in that era.
First of all, let's take a look at the longest of the three, and considered to be the most powerful Liaodong Gongsun family, the so-called "Eastern Kingdom". The founder of the Liaodong regime was Gongsun Du of Liaodong Taishou at the end of the Eastern Han Dynasty, who was born during the Huan Emperor's reign and was a member of the Xiangping clan of Liaodong. Initially, Gongsun Du was only a minor official in Xuanyu County, but at the recommendation of his fellow friend Xu Rong, he was made the Taishou of Liaodong by Dong Zhuo. Gongsun Du had a keen sense of politics, and he expected that the Han Dynasty had run out of energy, and Liaodong, located in the northeast corner, would become a good place to defend itself.
After making up his mind, Gongsun Du wholeheartedly governed Liaodong, and he used severe punishment to rectify the social atmosphere, and more than a hundred local heroes and strongmen alone were wiped out, which also achieved good results. After the county's neutral prestige, Gongsun Du set his sights on external expansion. At that time, Goguryeo and Karasuma near Liaodong County often plundered the people under Gongsun Du's rule, so he led an army to conquest and successfully defeated the two, and even many small tribes at that time were shocked by Gongsun Du's prestige and took the initiative to come to the rescue.
Gaining prestige in Liaodong made Gongsun Du grow day by day, so he started the idea of splitting the land and claiming the king. However, in order not to arouse public anger, Gongsun Du initially only gave him the posts of Marquis of Liaodong and Pingzhou Mu, and he divided Liaodong into two counties, Western Liaoning and Central Liao, and set up Taishou governance respectively.
In addition, Gongsun Du also sent troops across the sea to capture Donglai County, located on the Shandong Peninsula, and set up Yingzhou Assassin History to administer.
Although he only established himself as a marquis, Gongsun Du took advantage of the remote location of Liaodong and the convenience that outsiders knew little about to adopt the emperor's specifications when sacrificing heaven and earth in the suburbs and traveling, and actually regarded himself as the emperor of Liaodong.
Later, Cao Cao wanted to win over and appease Gongsun Du, so he made him a general of Wuwei and the Marquis of Yongning in the name of Tianzi, and Gongsun Du, who already regarded himself as king, was very dismissive of this, and even directly threw Yin Shou in the arsenal.
After Gongsun Du's death, the Liaodong regime was successively controlled by Gongsun Kang, Gongsun Gong, and Gongsun Yuan, who was a man of great ambition, who secretly united with Eastern Wu and was crowned the King of Yan by Sun Quan. However, after a period of exchange with Eastern Wu, Gongsun Yuan, fearing that he would be attacked by Cao Wei, beheaded wu's envoys and showed favor to Emperor Ming of Wei. After offending Eastern Wu, Gongsun Yuan offended Emperor Ming of Wei for his ill-treatment of his envoys, and in the first year of the Jing Dynasty (237), Gongsun Yuan took the initiative to send an army to attack Youzhou's assassin Shi Yiqiu Jian, and Cao Wei sent Sima Yi to conquest the following year, and soon completely destroyed the Liaodong regime.
In addition to the Liaodong regime that occupied the northeast, there was another regime in the northwest of Cao Wei that existed for more than thirty years, that is, the Fenghan regime established by Song Jian. In the first year of Zhongping (184), the Liangzhou warlord Song Jian took a fancy to this place, so he rebelled here and established himself as the "King of Pinghan". Because it was really remote, the princes of the Central Plains at that time did not care about this regime, which made it exist for more than thirty years.
In the nineteenth year of Jian'an (214), Cao Cao, who roughly pacified the princes around Guanzhong and Western Liang, sent Xiahou Yuan to conquer Song Jian, and the latter, who was good at long-distance raids, quickly defeated him, and Cao Cao said happily: "Song was built into a chaotic rebellion for more than thirty years, yuan was destroyed in one fell swoop, and the tiger stepped on the right and went forward. Although it was somewhat hasty to be wiped out, Song Jian was able to cause trouble in the northwest for more than thirty years, and there were still two brushes.
The Liaodong and Han dynasties were destroyed in opposition to Cao Wei, and the Jiaozhou regime was much wiser in comparison. At the end of the Eastern Han Dynasty, Jiaozhou's person Xie Xie was appointed as the Taishou of Jiaotong, who had a tolerant personality and was very affinity, so people who wanted to escape the war fled to Jiaotong, making this originally remote and backward place a paradise.
