In the Sui Dynasty, Emperor Wendi inherited the resources left by the Northern Zhou Dynasty, unified the whole country, carried out construction and defeated the Turks, thus pushing China to a new height in the Sui Dynasty.
Emperor Taizong and Emperor Gaozong were at the peak of their power. They defeated Turkey, North Korea and Japan, and a diplomat pushed India by half. By the time of Xuanzong, the economy reached the peak of the Tang Dynasty, and no one could compete with the Tang Dynasty except the Arab Empire. But then Gao Xianzhi led thousands of Tang Jun to defeat in the war with hundreds of thousands of Arabs, resulting in Central Asia being controlled by Arabs. The war had a great influence on the history of the whole world. Then the Anshi Rebellion broke out and the Tang Dynasty quickly weakened.
From the Northern Song Dynasty to the Southern Song Dynasty, the economy reached the peak before the feudal era and even the industrial era of all mankind, and the system of the Song Dynasty was the most reasonable in China's successive dynasties, so the cultural development of the Song Dynasty was less oppressed by imperial power than other dynasties. But in the end, the Song Dynasty was unable to make achievements in foreign wars. In the late Southern Song Dynasty, although China was the richest country in the world, militarily speaking, Temujin was in Mongolia and Genji of Japan unified Japan. The Western King Lion Heart befriended Saladin, which doomed its era to be a tragedy of the Song Dynasty.
Zhu Yuanzhang made the Ming Dynasty very serious from the beginning. In the end, the whole society can't get rid of the phenomenon of attacking and opposing each other. It is no wonder that successive emperors of the Ming Dynasty, starting from Yingzong, did nothing, and a few Ren Gang disappeared into the palace when he succeeded to the throne. But it happened that in the days when there was no emperor, it was the time when the Ming Dynasty was the most peaceful and peaceful, the whole country was operating normally, and the sage Rainbow Yangming appeared. Therefore, some people later compared the Ming Dynasty to the earliest constitutional monarchy country in the world-although there was an emperor, in essence, the emperor had or did not have it. The strongest era of Ming Dynasty was in Yongle Dynasty, when no other country in the world could compete with China. This strength continued until the Wanli Dynasty, when China was always the overlord in the world.
