Starting from Empress Wu Zetian, the emperors of the Tang Dynasty seemed to have a natural fear of the term ’empress’, which mainly came from the years when yin and yang were reversed.
During the approximately three hundred years of the Tang Dynasty, the empress only reigned for seventy-two years, and did not reign for the rest of the time. That is to say, more than three-quarters of the Tang Dynasty did not have a queen.
Moreover, observing the situation during the 72 years of the empress’s reign, Wu Zetian alone lasted for over 23 years, accounting for one-third of the total, while the other empresses combined accounted for less than half of the total.
This fact indicates that the long reign of the empress played a significant role in Wu Zetian’s seizure of power, and after Wu Zetian, a series of women’s political turmoil also caused great headaches for the Tang royal family.
After Empress Wu Zetian, Empress Wei rebelled, followed by Shangguan Wan’er, Princess Taiping, and others. These women saw that Empress Wu Zetian could rise to power, so they also had the same dream as Empress Wu Zetian. In the more than ten years after her death, there were constant coups in the Tang court, and various forces fought fiercely against each other, causing chaos throughout the court.
In the end, it was the wise and powerful Li Longji who put an end to all of this. He executed Shangguan Wan’er, despite her unjust death and forcing his aunt, Princess Taiping, to commit suicide. He ultimately put an end to the situation of women’s tyranny, valued virtuous ministers, and pushed the glory of the Tang Dynasty to its climax.
When Li Longji was young, there was also an almost replica of the Wu Zetian era, which was the event of abolishing the king and establishing martial arts. At that time, Emperor Xuanzong of Tang Dynasty liked Empress Wu Huifei very much, but did not like Empress Wang. Moreover, this Empress Wu Huifei was a member of the Wu Zetian clan and almost staged the event of abolishing the king and establishing martial arts during the Li Zhi era.
Later, Empress Wu Huifei died of illness, which directly led to the failure of the hope of Prince Shou Li Mao being crowned as the crown prince. Of course, this was not the most tragic thing. The most tragic thing was that Emperor Xuanzong was very sad because of Empress Wu Huifei’s passing, so eunuch Gao Lishi tried every means to make the emperor happy.
So after thinking about it, his mind unexpectedly shifted to his daughter-in-law. That’s how when Empress Wu Huifei was alive, Li Longji carefully selected a daughter-in-law for his son Li Mao, but now she has become his own woman. This kind of thing can only be done by the Tang Dynasty.
In this way, there was still a glimmer of hope for the position of crown prince, but this time it is completely hopeless. From then on, Emperor Xuanzong of Tang began to be addicted to Yang Yuhuan’s beauty, and his attitude was not as positive as before.
But no matter how addicted he was, Li Longji’s background remained unchanged. As an emperor, he once killed three sons in one day with the aim of consolidating imperial power and suspecting his own son of plotting rebellion.
Killing three sons in a day is something that can be done, so for the stability of the imperial power itself, no matter how much Li Longji likes Yang Yuhuan, he will not crown her as empress.
And even if the courtiers pretend to be deaf and mute, everyone knows in their hearts what the origin of Yang Yuhuan is. You can now become a concubine in the palace, but it is very difficult to truly become a queen.
Taking into account the factors of Empress Wu Zetian and the origin of Yang Yuhuan himself, Emperor Xuanzong of Tang ultimately did not bestow the title of Empress upon Yang Yuhuan. However, Yang Yuhuan’s actual power was not inferior to that of Daiyu, which was not inferior to that of Huang Later.
