The Warring States period was a time of intense conflict in ancient China, lasting from about 475 to 221 BCE. During this era, several powerful states fought for dominance, leading to constant battles and shifting alliances. This chaotic environment fostered significant advancements in military strategy and political thought, as leaders sought ways to unify the region. Amidst the turmoil, influential philosophers like Confucius and Laozi emerged, shaping ideas about governance and ethics. The period ultimately ended when the Qin Dynasty unified the states, laying the foundation for a centralized imperial system that would last for centuries.
