The first emperor of our country was Qin Shi Huang, who reigned for 12 years, and the last emperor was Puyi, the Xuantong Emperor, who reigned for 4 years and was forced to abdicate by Yuan Shikai. From the beginning of Qin Shi Huang to the end of Puyi, China's feudal imperial system existed for more than two thousand years, producing a total of 494 emperors, some of whom only did a few days, and only these 5 emperors reigned for more than 50 years.
1. Emperor Wu of han
Emperor Wudi of the Han Dynasty was the first emperor in China's history to reign for more than 50 years, he ascended the throne in 141 BC, died in 87 BC, and was emperor for 55 years. Emperor Wu of Han reigned for a long time, but he did not have a chaotic life, nor did he covet pleasure and extravagance, but made many achievements, which made him an emperor who could rival Qin Shi Huang.

Emperor Wu of Han took the throne at the age of 16, and after coming to power, he learned the lesson of the rebellion of the Seven Kings during the period of his father Emperor Jing of Han, and did not rush to cut the domain, but adopted a more secure "Tui En Order", allowing the king of the clan to divide his own land among his sons, which made the huge kingdom of the clan divided into many, and the strength of the han wu was greatly reduced in an instant, and it was no threat to the han wu emperor, and the king of the clan became the fish meat to be slaughtered by the han wu emperor.
After solving the problem of the domestic feudal king, Emperor Wu of Han set his sights on the strong enemy Xiongnu, and he sent Wei Qing, Huo Zhiyi and other generals to lead troops to attack the Xiongnu, dealing a heavy blow to the Xiongnu's living forces, and also seizing the Xiongnu's Heshuo, Hetao and other regions, expanding the territory of the Han Dynasty.
Emperor Wu of the Han Dynasty also carried out reforms at home, implementing policies such as equalization, equalization of losses, calculation, reckoning, and suppression of merchants, which promoted the economic development of the Han Dynasty. Emperor Wudi of the Han Dynasty also established Taixue, exalted Confucianism alone, deposed hundreds of families, etc., established the orthodox status of Confucianism, and influenced the history of our country.
Second, Li Qianshun
Li Qianshun was the fourth emperor of Western Xia, who ascended the throne in 1086 and died in 1139, reigning for 53 years. When Li Qianshun first ascended the throne, he was only a 3-year-old child, and the dictatorship of his grandmother Empress Liang and his mother's family forces led to the deepening of domestic contradictions, and in order to divert the contradictions, they frequently launched wars against the Song, resulting in the people suffering from the war and making Empress Liang even more unpopular.
In 1099, the Liao Dao sect sent people to kill Empress Liang and help Li Qianshun start a pro-government. After the conquest, Li Qian began to negotiate peace with Song and Liao, and won a stable external environment for Western Xia. At the same time, he also met around the Song and Liao countries, avoiding being destroyed by the Song and Liao. Li Qianshun also straightened out the administration of officials, reduced taxes, paid attention to agricultural and mulberry farming, and built water conservancy projects, thus reducing the burden on the people and promoting economic development.
3. Li Renxiao
Li Renxiao was the fifth emperor of Western Xia, who ascended the throne in 1139 and died in 1193, reigning for 54 years. Li Renxiao was a very talented emperor, and after he ascended the throne, he created a stable external environment for Western Xia by forging a good alliance with the Jin Dynasty. At home, he reused the more educated party and Han ministers to help him preside over state affairs. Li Renxiao also opened schools at all levels, practiced imperial examinations, and respected Confucianism, which promoted the cultural and economic development of Western Xia and brought Western Xia into a period of strength and prosperity.
At the same time, during Li Renxiao's reign, the emphasis on literature and light weapons led to the decline of Western Xia's armaments, the weakening of combat effectiveness, and the repeated failures of foreign wars in the late Western Xia, which led to the decline of Western Xia. In general, Li Renxiao's contribution was greater than that, and he brought a period of peace and prosperity to Western Xia.
4. Kangxi
Kangxi was the fourth emperor of the Qing Dynasty, he ascended the throne in 1161 AD, died in 1722, reigned for 61 years, the longest reigning emperor in China.
When Kangxi ascended the throne, he was only an 8-year-old child, assisted by four ministers, Soni, Aobai, Suksaha, and Shubilong, but later formed a situation in which the Aobai family was dominant, which made Aobai become arrogant and wanton, and already threatened the imperial power. Kangxi trained a group of pro-noble disciples, and when Aobai was defenseless, he let them capture Aobai, which allowed Kangxi to overthrow Aobai and realize pro-government.
After the realization of pro-conquest, Kangxi rectified the rule of officials, exempted money and grain, and repaired and ruled Caoyun, which made the Qing Dynasty enter a prosperous period. At the same time, Kangxi also quelled the Rebellion of the Three Domains, recovered Taiwan, expelled Tsarist Russia, etc., and was a very meritorious emperor through the ages, but in his later years, he did not deal with the issue of Li Chu well, which triggered the nine sons to seize the concubine incident, and the 9 brothers participated in the conquest incident, resulting in infighting and frame-up between the sons.
Fifth, Qianlong
Qianlong was the sixth emperor of the Qing Dynasty, who ascended the throne in 1735 and abdicated in 1796 for 60 years. Qianlong could have become the longest reigning emperor in China's history, but because he did not want to surpass Kangxi, in 1796 AD, he took the initiative to cede the throne to his son Jiaqing, and Qianlong served as emperor for three years, and died in 1799 at the age of 89.
At the beginning of Qianlong's reign, due to the accumulation of the Kangxi and Yongzheng periods, he took over a prosperous and powerful country, and Qianlong was also quite capable, and he maintained the prosperity of the Qing Dynasty. At the same time, Qianlong also quelled the miaojiang rebellion and won the Battle of Zhan, the Battle of Amulsana, the Battle of Tianshan South Road, the Battle of Jinchuan, the Qing-Burma War and other wars, laying the map of the Great Qing Dynasty and allowing the Great Qing to enter its heyday.
At the same time, in Qianlong's later years, he was extravagant and extravagant, six times in Jiangnan, conniving at the corruption of He Yan and others, as well as the daxing literary prison, and the implementation of the policy of closing the country to the outside world, which led to the decline of the Great Qing, which led to the gradual backwardness of the Great Qing to the Western countries and caused the misfortune of China's modern society.
