Northern Chinese nation (228-222 BCE)
Not to be confused with the various other
states of Dai in Chinese history.
Dai was a short-lived state from 228 BC to 222 BC[1] during the Warring States period of Chinese history. Prince Zhao Jia, older brother of King Youmiu of Zhao, fled with the remnant forces to Dai Commandery after the conquest of Zhao[1] and was proclaimed the new king of Zhao. His rump state was conquered in the year 222 BC by Qin[1] during its campaigns against Yan. The ruins of his capital are preserved in present-day Yu County, Hebei, as "Dai King City" (代王城).
