China's Warring States period

The Warring States period (475–221 BC) in China was a time of intense conflict among several powerful states vying for dominance after the decline of the Zhou dynasty. These states developed advanced armies, innovative warfare, and bureaucratic systems, shaping Chinese civilization. It was marked by frequent wars, shifting alliances, and philosophical debates, notably Confucianism, Daoism, and Legalism, which influenced ruling strategies. Ultimately, the state of Qin unified China under Qin Shi Huang in 221 BC, ending the period and beginning imperial China. This era significantly contributed to China's political, military, and cultural development.
