Looking at history, the youngest emperor in history, Han Shangdi Liu Long, Han Shangdi Liu Long is the youngest emperor in history to ascend the throne. He was born in 105 AD and ascended the throne in 106 AD, only about 100 days after birth. Han Shangdi Liu Long was the youngest son of Han He Emperor Liu Zhao. Due to the early deaths of most of Han He Emperor's other sons, Liu Long was secretly sent to the common people for upbringing. After Han He Emperor's death, Liu Long was brought back to the palace to ascend the throne, becoming the fifth emperor of the Eastern Han. However, Liu Long passed away just 220 days after taking the throne, making him the emperor with the shortest lifespan in Chinese history. Besides Han Shangdi Liu Long, there are other emperors who ascended to the throne at a young age in history, such as the Western Xia Emperor Yizong Li Liangzuo who ascended at the age of two, Jin Mu Emperor Sima Dan who ascended at two years old, Han Chong Emperor Liu Bing who ascended at one year old, Northern Wei Young Ruler Yuan Zhao who ascended at three years old, and Song Gong Emperor Zhao Xian who ascended at four years old. These emperors ascended to the throne at a young age, with their mothers or maternal relatives acting as regents. Source: Baidu AI.
