The monarch gave the land to the imperial clan and heroes, and let them build a country on this land. A similar feudal system was implemented in medieval Europe. It is also a metaphor for being conservative, conservative and not open. The feudal system in China began in the Western Zhou Dynasty in 1 1 century BC, and was gradually replaced by centralized system after the establishment of the Qin Dynasty in the 3rd century BC. The feudal system in Europe prevailed in the Middle Ages from the 5th century to15th century, and declined with the rise of nation states in16th century and17th century.
Japanese feudal system originated from heian period's legal system in the 8th to12nd century, and became the mainstream system in the era of military regime in the 8th to19th century, ending in the Meiji Restoration in the second half of19th century.
The feudal system was completely replaced in the Qin Dynasty.
During the Spring and Autumn Period and the Warring States Period, although the enfeoffment system initiated by the Western Zhou Dynasty still existed in name only, the authority of the Zhou Emperor was completely absent, and local governors were in chaos. Ying Zheng, king of Qin, conquered six countries in the east and unified the Central Plains for the first time in history.
After the establishment of the Qin Dynasty, Ying Zheng strengthened centralization in many aspects, and implemented the county system for the first time in the whole country. From then on, it marked that the feudal system was completely replaced. In other words, the predecessor of the Qin Dynasty, Qin State, was the product of the feudal system, but it was also the terminator of the feudal system. During the Western Han Dynasty and the Eastern Han Dynasty, feudalism was intermittent in China, but it continued on the whole. It was at this time that the pattern of wang xing's different surnames was started, but it soon ended.
