The Spring and Autumn Period and the Warring States Period (770 BC-22 BC1year) was a great split period in the history of China. The Eastern Zhou Dynasty was destroyed by Qin at the end of the Warring States Period (256 BC), so the Spring and Autumn Period and the Warring States Period were not completely included in the Eastern Zhou Dynasty. During the Western Zhou Dynasty, the Emperor of Zhou maintained the authority of the world. After Pingdong moved eastward, the Zhou family began to decline in the Eastern Zhou Dynasty, and only retained the title of the Lord of the World, without actual control ability. Due to the different social and economic conditions, countries in the Central Plains compete for hegemony among big countries, and the merger and hegemony of various countries have contributed to the unification of various regions. Therefore, the social unrest in the Eastern Zhou Dynasty prepared conditions for national reunification.
Spring and Autumn Period and Warring States Period are divided into Spring and Autumn Period and Warring States Period. The watershed was in 453 BC, when Han, Zhao and Wei wiped out the Zhi family and carved up the State of Jin.
The Spring and Autumn Period, referred to as the Spring and Autumn Period for short, refers to the period from 770 BC to 476 BC, belonging to the Eastern Zhou Dynasty. During the Spring and Autumn Period, Zhou Wang's influence weakened, and the princes fought with each other. Qi Huangong, Jin Wengong, Song Xianggong, Qin Mugong, and Chu Zhuangwang have successively dominated, and they are known as the Five Overlords in the Spring and Autumn Period (another way of saying it is that the Five Overlords in the Spring and Autumn Period are Qi Huangong, Jin Wengong, Chu Zhuangwang, Wu Wang He Lu and Yue Wang Gou Jian).
The warring States period, referred to as the warring States period, refers to the period from 475 BC to 22 BC1year. In the history of China, from the late Eastern Zhou Dynasty to the unification of the Central Plains by Qin Dynasty, countries fought endlessly, so it was called the Warring States Period by later generations.
