1. The youngest emperor in Chinese history actually appeared in the Han Dynasty, that is, the fifth emperor of the Han Dynasty, Liu Long, the Han Shang Emperor. When he ascended the throne, the emperor set a historical record for his age. Only 100 days old, that is to say, a baby born only 100 days ago, was already the nominal supreme ruler of the great empire.
2. In fact, according to the convention, it is not the turn of the little emperor to ascend the throne. At that time, Emperor Hanhe had just died. According to the order of succession of his eldest son, Liu Sheng, the eldest son of Emperor Hanhe, should succeed to the throne. This Liu Sheng was not Liu Sheng, the King of Zhongshan who had relations with Liu Bei, but another prince of the same name. The prince has been suffering from a strange disease since he was a child, and he has been cured for many years without being able to recover.
3. For this reason, in addition, the empress of the Emperor Hanhe wanted to control the government, so she accused Liu Sheng of not being suitable for inheriting the throne. Instead, Liu Long, who was born just over a hundred years ago, was appointed the new emperor, changing the current year title to Yanping, and granted Liu Sheng, the original successor to the throne, a king of plains.
4. However, the youngest emperor was also unlucky. He died prematurely just over 200 days after becoming the emperor, when he was less than one year old. Because he died young, the posthumous title of the deceased emperor was "Xiao Shang", which was called Han Shang Emperor.
5. The Han Shang Emperor was not only the youngest of hundreds of Chinese emperors when he ascended the throne, but also the shortest lived emperor among them. Therefore, he was called the "Hundred Day Emperor" or "August Emperor" by later historians.
