The Eastern Zhou period (770-256 BCE) was a significant era in ancient Chinese history, following the Western Zhou. It is divided into two main periods: the Spring and Autumn period and the Warring States period. This time was marked by the decline of central authority and the rise of regional states, leading to increased warfare and political fragmentation. During the Eastern Zhou, notable philosophical schools emerged, including Confucianism and Daoism. The period also saw advancements in technology, agriculture, and military strategies. Ultimately, the Eastern Zhou ended with the unification of China under the Qin Dynasty, which marked the beginning of imperial rule.
