The term "warring states" refers to a historical period characterized by intense conflict and competition among various states or regions. This concept is often associated with the Warring States period in ancient China, which lasted from approximately 475 to 221 BCE. During this time, several states fought for dominance, leading to significant political and military developments. The Warring States period saw the rise of powerful leaders and the establishment of new strategies in warfare. It ultimately culminated in the unification of China under the Qin Dynasty, which marked the end of the fragmented state system and the beginning of a centralized imperial rule.
