Why are some emperors called Emperor Wen, some called Emperor Wu, some called Taizong and some called Taizu? These titles were given to him by the emperor himself? What are the titles?
To answer these questions, we must first know the classification of emperor titles, which generally have three main categories: name, temple number, and era number.
First, let's talk about the title, that is, after the emperor's death, people give him an evaluative title based on what he did during his lifetime. For example, Emperor Wen of Han, as the name suggests, is a heavy text in governing the country! Emperor Wu of Han liked to use force, could never move his hands, and often launched wars, so the Xiongnu were picked up enough. Wen and Wu are positive, some are derogatory. Like the Han Dynasty Emperor, it is pejorative, not a good title! There is a TV series called "Kangxi Dynasty", in which there is a filial piety empress, which is also a nickname, indicating that this person is filial piety and dignified. But there is a big mistake in this TV series is that Empress Xiaozhuang opened her mouth and closed her mouth: "How can I filial piety be?" This screenwriter lacks historical common sense, and it is impossible for the parties to know their nicknames before they die.
Let's talk about the temple number, that is, the title of the tablet enshrined in the royal family temple after the emperor's death. That is, the ancestral tablets often said by the people, so they generally have such words as zu ah zong, such as the more famous Tang Taizong and Song Taizu.
Finally, let's talk about the year number, which is used to chronicle. Emperors of the Qing Dynasty were generally called era names, such as Kangxi and Yongzheng. Kangxi's first year as emperor was Kangxi's first year, and Kangxi's sixty years meant that this emperor had been working for 60 years. If you change an emperor, you have to change your era name, otherwise it will be chaotic.
