How did Wu Zetian become the only female emperor in Chinese history?

Very few people in Chinese history are as famous or talked about as Wu Zetian (624–705 AD), who stands alone as the single woman to ever grab the title of Emperor Huangdi) all by herself, ruling the Tang lands before starting her own Zhou rule.

First Step into the Palace

Wu’s story started at age fourteen when she was picked as a low-level concubine cairen) for Emperor Taizong, the second Tang king, and although she was first called "Wu Mei" (meaning charm) and had little power, this time was key for her to learn court life because while other women just tried to please the king, Wu studied how to run the state, read books, and learned history, plus she got the attention of the king’s son, Li Zhi (later Emperor Gaozong), which helped her rise later.

Coming Back and Joining Gaozong

When Taizong died in 649 AD, rules said women without children must go to Buddhist temples, so Wu stayed at Ganye Temple for some years until Li Zhi became Emperor Gaozong and brought Wu back to the palace around 651 AD, at which time Gaozong’s main wife, Empress Wang, was fighting hard with another woman, Consort Xiao, and even though Empress Wang thought she could use Wu to hurt Consort Xiao, Wu quickly won the emperor’s full love, leading Gaozong to remove both Empress Wang and Consort Xiao (who were later killed by Wu’s order) by 655 AD and make Wu the new Empress.

Getting Stronger as "Heavenly Empress"

After becoming Empress, Wu did not stay quiet because Emperor Gaozong was very sick (maybe high blood pressure and bad eyes), so he needed Wu to help run things, meaning she started going to court meetings behind a screen next to the emperor and soon spoke directly to officials, earning them the name "Two Saints" Er Sheng) which meant they shared power equally, while Wu also slowly got rid of rich families and officials who hated her by putting her own loyal people in their places using better tests for government jobs, so power moved from old rich families to new scholars who owed her everything.

Power as Empress Dowager and Regent

When Gaozong died in 683 AD, Wu moved faster as their son, Li Xian (Emperor Zhongzong), became king for a short time, but when he tried to be independent and help his own family, Wu kicked him out after only two months, then put another son, Li Dan (Emperor Ruizong), on the throne while keeping him locked up, and since Wu called herself Empress Dowager and started ruling from behind a curtain in a practice called "running the court," she was the real boss for seven years by giving orders and leading the army while her son just pretended to be king.

Making People Believe She Should Rule

To break the biggest rule of a woman as Emperor, Wu needed a good reason in a society that wanted men to lead, so she used smart tricks like pushing Buddhism harder than Taoism or Confucianism and paying writers to say Buddhist books predicted a female ruler while she claimed to be the Future Buddha reborn, plus she made new Chinese characters (even for her own name,Zhao, meaning "sun and moon shine") and changed names of offices and cities to show a new time, and her friends even made up "good signs," like strange rocks or sky events, saying heaven sent these to support her.

Starting the Zhou Dynasty (690 AD)

By 690 AD, everything was ready since her enemies were gone, her friends ran the government, and people believed the religious stories, so Wu made her last move by forcing her son, Emperor Ruizong, to quit and give the throne to her, leading to October 16, 690, when Wu Zetian officially named herself Holy and Divine Emperor Sheng Shen Huang Di) and started the Zhou Dynasty, marking the one and only time a woman sat on the dragon throne as the true boss, not just helping a man.

Conclusion

Wu Zetian’s path to power shows great skill and strong will because she used every chance from her early days to her time as regent to get control, and by being cruel to enemies but also good at running the country and using smart stories, she broke the barrier for women, ruling well for almost fifty years until she was removed in 705 AD, proving she could beat a system built for men.
