The reason why Chen Ajiao was abolished is from the period of Emperor Wen. After Emperor Wendi ascended the throne, in order to prevent the consorts from dominating the family, they fostered the families of their mother, Queen Bo, and Queen Dou, respectively, so that the two consorts restricted each other. At that time, the power structure was two consorts groups, namely, the central hero group and the local warlord Liu group.
Later, Emperor Wen of the Han Dynasty married the Crown Princess of the Empress Dowager Bo for his son, the later Emperor Jing of the Han Dynasty. However, after Emperor Jing of Han Dynasty ascended the throne, he deposed the thin queen arranged for him by Emperor Wen in a few years, chose to make the king the new queen, that is, the carpenter of Emperor Wu of Han Dynasty, and then naturally made Emperor Wu of Han Dynasty the prince.
In fact, the marriage between Emperor Wu of the Han Dynasty and Empress Bo is similar. Emperor Wu of the Han Dynasty deposed Chen Ajiao shortly after he ascended the throne. The main reason lies in the forces behind Chen Ajiao. Emperor Wu is an ambitious emperor. After he ascended the throne, he will certainly foster new consorts and new interest groups. Chen Ajiao himself was born in an active Chen family, as well as a consort like Dou Taihou. It is impossible for Emperor Wu to support them.
From the Wei father and son who were fostered by Emperor Wu of the Han Dynasty after he abolished Chen Ajiao, we can also see the purpose of doing so. Wei Zifu has no substantive relationship with the above-mentioned power groups. She is just a singer of Princess Pingyang, the sister of Emperor Wu of Han Dynasty. Although Wei Fuzi was strongly supported by Princess Pingyang as a queen, Wei Fuzi was independent of Princess Pingyang, so Wei Fuzi's knighthood was equivalent to a new consort force.
Throughout the history of the Han Dynasty, old consorts constantly abdicated and new consorts constantly appeared. In the final analysis, those in power don't want their consorts to be strong for more than two generations in a row, and deposing the queen is just a way for them to balance the forces of all parties.
