Defining the Warring States Period
The Warring States Period, known in Chinese as Zhanguo, represents the final phase of the Zhou dynasty’s decline before the rise of the first imperial dynasty.

By the beginning of the Warring States era, dozens of states had been absorbed, leaving a handful of dominant players locked in a struggle for supremacy known as the contest for Tianxia, or “all under heaven.”

- Middle Warring States (350–260 BCE): The era of great reformers, famous strategists, and massive battles that reshaped the map of China.
- Late Warring States (260–221 BCE): The relentless expansion of Qin and the final annexation of the remaining six major
