In the second year of Xiantian (713), Emperor Xuanzong of the Tang Dynasty launched a coup, regaining power from the Supreme Emperor Tang Ruizhong and completely eliminating the power of Princess Taiping. It was known as the "Xiantian Coup" in history. According to historical records, the main reason why Tang Xuanzong Li Longji launched the "congenital coup" was that Li Longji learned that Princess Taiping intended to rebel and had to take action.

What is strange is that during the entire process of the "Innate Coup", Li Longji first got rid of the prime minister who was attached to Princess Taiping, and then forced Tang Ruizhong Li Dan to hand over the supreme power, but he did not Take action against the "culprit" Princess Taiping and let her escape Chang'an on her own. So why didn't Li Longji list Princess Taiping as a target?

First of all, according to the analysis of historical data, it can be found that Princess Taiping did not prepare to rebel at that time. The so-called record of Princess Taiping's intention to rebel was most likely an excuse created by Li Longji to legitimize the "congenital coup". Since Princess Taiping did not really rebel, Li Longji's "innate coup" naturally would not target Princess Taiping.

Secondly, the fundamental issue during the Xiantian years was the power structure issue between the Supreme Emperor Li Dan and the Emperor Li Longji. Princess Taiping just used this power structure issue to cause trouble. Li Longji's first goal in launching the "Innate Coup" was to regain his rights from the hands of the Supreme Emperor Li Dan, and getting rid of Princess Taiping was only a secondary goal.

Thirdly, the reason why Princess Taiping was able to intervene in the government affairs at that time mainly relied on two aspects: first, the power of the Supreme Emperor Li Dan; second, the prime minister who was dependent on Princess Taiping. After Li Longji regained power through the "congenital coup" and purged Princess Taiping's prime minister, Princess Taiping actually had no political significance worth attacking.
