Zhongshan State: Ancient Chinese State During the Warring States Period

There is no such country as 'Zhongshan Guo' (中山国) in modern times. However, in ancient China, there was a state called Zhongshan (中山) during the Warring States period (475-221 BCE). It was located in present-day Hebei province and was known for its powerful military and strategic location. The state was eventually conquered by the state of Qin in 296 BCE.
