The empress system in China came into being with the emperor system, so the first empress was born in the history of China. Before that, there must be an emperor and then a queen. Qin Shihuang was the first person to establish the emperor system. After he unified the six countries, he began to implement "cars on the same track, books on the same language, and unified measurement" throughout the country. Moreover, Qin Shihuang thought that he was "a Huang San with both ability and political integrity, and made great contributions to the Five Emperors", and he was called "Emperor" only by linking "Emperor" with "Emperor". The Qin Dynasty was a very short-lived dynasty, and Qin Shihuang and Hu Hai had not had time to establish a queen.

The Han Dynasty inherited the Qin system, and Liu Bang replaced the Qin Dynasty to establish the title of "Emperor" as the supreme ruler after the Han Dynasty, while Liu Bang's original wife was posthumously sealed as the queen, so the first recorded queen in China history was.

When Lv Zhi married Liu Bang, he was still a small tingchang, and he followed Liu Bang all the time. When Liu Bang established the Han Dynasty, Lv Zhi still had some credit. But after Liu Bang's death, Lv Zhi monopolized the power, and made Mrs. Qi of Liu Bang throw herself into the cesspit and drown, which can be said to be ruthless. This also shows from another aspect that if you want to win the favor of the emperor in the harem, you must not only have certain beauty, but also have certain means.

The emperor system in China ended with the end of feudal society in China, and so did the empress. According to incomplete statistics, there are 493 emperors and almost 800 empresses in China. Because in the feudal society of China, the emperor can be abolished except in special periods, and basically no one has the right to abolish the emperor; The queen is different. Sometimes, an unpopular queen can still be abolished by the emperor.
