Why was the princess, who was deeply favored by the emperor, ultimately deposed as a palace maid

During the Tang Dynasty, there was a princess whose life was very peculiar, and this woman was Princess Anle Li Hou’er. Below, the History Encyclopedia editor will provide a detailed introduction to the relevant content.
Princess Anle’s father was Emperor Tang Zhongzong Li Xian. Shortly after Princess Anle’s birth, Emperor Tang Zhongzong Li Xian was at the lowest point of his life. However, the birth of Princess Anle became a source of comfort for Emperor Tang Zhongzong Li Xian, and shortly after her birth, she followed Emperor Tang Zhongzong Li Xian to travel around, experiencing many hardships. So after Emperor Zhongzong Li Xian ascended to the throne, he showed great affection and tolerance towards Princess Anle. Whatever Princess Anle wanted, Emperor Zhongzong Li Xian would not hesitate to bestow upon her.
So Princess Anle, who was deeply loved by Emperor Tang Zhongzong Li Xian, gradually developed a stubborn and willful personality. Before getting married, she had an affair with Wu Chongxun and even became pregnant with his child. Later, Emperor Tang Zhongzong Li Xian married Princess Anle to Wu Chongxun, but Princess Anle became entangled with her husband’s cousin. After Wu Chongxun passed away, Princess Anle married his cousin. Even later, Princess Anle wanted Emperor Tang Zhongzong Li Xian to depose the crown prince and establish herself as the “Empress Dowager”, but she was rejected by Emperor Tang Zhongzong Li Xian.
Later, Princess Anle used her identity to buy and sell official positions, and even conspired with her mother Wei Shi to poison Tang Zhongzong Li Xian. In the end, she planned to make her young brother the new emperor while she and her mother Wei Shi held great power. However, Princess Anle’s plan did not materialize. Later, Li Longji and Princess Taiping joined forces to destroy Princess Anle’s plan. In the end, Princess Anle’s identity was downgraded to that of a palace maid, and the funeral arrangements after her death were very simple and hasty.
