There are not a few emperors in Chinese history, and the most well-known ones are the Qin Emperor Han Wu and the Tang Emperor Song Zu. However, although some emperors were domineering, they were not so tough on the outside world, and the most tough emperors on the outside world were the following at that time.
Qin Shi Huang
1. Qin Shi Huang
Qin Shi Huang was the first emperor in history, and Yu Yu of Fen VI united the world, established a centralized unified state, opened up a new era, and was known as the first emperor of the ages. After Qin Shi Huang destroyed the Six Kingdoms and unified China, there was still a major problem in the north, that is, the Xiongnu.
During the Warring States period, the Qin state and the six kingdoms of Shandong attacked each other, and there was no time to take care of the Xiongnu, and later the Zhao state sent the famous general Li Mu to attack the Xiongnu, and since then the Xiongnu have not dared to invade the Zhao state. After Qin Shi Huang unified China, the Xiongnu often invaded the Qin Dynasty, and Qin Shi Huang sent the general Meng Tian to beat the Xiongnu for more than ten years and did not dare to attack.
Liu Che
2. Emperor Wu of han
Emperor Liu Che of the Han Dynasty was one of the most domineering emperors in history, and his Wenzhi martial arts were recorded in the annals of history, and few emperors in previous dynasties could look up to him. After the Western Han Dynasty was ruled by Wenjing, by the early years of Emperor Wu of Han, the national strength was already very strong, and the heroic Emperor Wudi of Han began to fight back against the Xiongnu, and fought for more than 40 years, so that the Xiongnu were no longer a border problem.
The Han Dynasty was the most powerful country at that time, so the Han envoys were particularly dragged when they went to the countries of the Western Regions and were often killed. Emperor Wu of han was very angry every time he heard that han envoys had been killed, for example, the South Yue State killed the Han envoys, resulting in the destruction of the South Yue Kingdom. The King of Joseon killed the Han envoys, and Emperor Wu of Han sent troops to destroy Korea. Whoever dares to kill the messengers of the Han Dynasty will destroy his country. Emperor Wudi of Han was such a domineering person.
Yang Guang
3. The Sui Emperor
The Sui Emperor Yang Guang was always regarded as a tyrant because he abused his people's power and caused chaos in the world, which eventually led to the demise of the Sui Dynasty. However, Yang Guang was a sin at that time, and the emperor who contributed to the thousands of years had a far-reaching impact on the excavation of the Grand Canal and the construction of the Eastern Capital. One of the main reasons for Yang Guang's fall was frequent wars, which was also his tough attitude toward the outside world.
During Yang Guang's reign, he opened up territory and expanded the territory, similar to the Qin Emperor Han Wu, except that in the end he failed. Yang Guang twice sent emissaries to "comfort" Ryukyu, but Ryukyu did not agree, so Yang Guang sent troops to attack Ryukyu, killing its master Huan si thirsty and stabbing, capturing thousands of men and women. But Yang Guang was the only emperor of the four who could not subdue his opponents.
Zhu Di
4. Ming Chengzu
Ming Chengzu Zhu Di was one of the few emperors in history with the toughest attitude towards the outside world, and the Ming Dynasty became a country under the rule of Zhu Di. Although Emperor Wu of Han and Emperor Taizong of Tang repeatedly broke the nomadic people, they all sent generals to conquest, and only Ming Chengzu Zhu Di led the army to personally conscript.
Zhu Di personally conquered Mongolia five times to further attack the remnants of the Yuan Dynasty, and Annam had been restless since the end of the Yuan Dynasty, and after Zhu Di took the throne, he sent troops to conquer all of Annam. Placing over to The Imperial Household and giving direct rule over Vietnam, Annam also began to pay tribute to the Ming Dynasty.
