Yan state

The Yan state was an ancient Chinese kingdom during the Warring States period (475-221 BCE), located in what is now northern China. It was one of several powerful states vying for control before China's unification. Known for its strong military, cultural development, and strategic geographic position, Yan played a significant role in the political and military conflicts of its time. Its capital was in modern-day Beijing. The state eventually fell to the Qin kingdom, which unified China. Yan's history reflects the complex political dynamics and warfare of early Chinese civilization.
