Qin Shihuang was the first monarch to complete reunification in feudal times, and his historical position was self-evident. Qin Shihuang ushered in an era, from which China entered a feudal era of more than 2,000 years, which had a great influence on the history of the Chinese nation. Ying Zheng, king of Qin, destroyed the six eastern countries successively and established the first unified and centralized feudal country in Chinese history. The unification of Qin dynasty ended the long feudal feudalism, which was in line with the wishes of the broad masses of people. After Ying Zheng unified the six countries, it took a series of measures to strengthen centralization.
The second Qin Dynasty perished, and Liu Bang was the founder of the Han Dynasty. The Han Dynasty was the first feudal dynasty to rule for many years, which laid the tone of the feudal era. Many dynasty systems in later generations were formulated with reference to the Han Dynasty, which also formed the largest Han nationality in the Chinese nation. The Han Dynasty established by Liu Bang lasted for more than 400 years, and it was the first dynasty in China's history with long-term stability under the unified environment. Although there was a system of enfeoffment, the main theme of the Han Dynasty was centralization. In the centralized environment, many strategies for governing the country have been put forward, and the benefits of reunification have been deeply rooted in the hearts of the people.
Every founding monarch is the end of the last era, but also opens a new era. They left a deep impression in the long history, and their efforts created one feudal dynasty after another.
