Prince of Dai

Prince or King of Dai was an ancient and medieval Chinese title.

King of Dai is sometimes used to describe the heads of the Baidi state of Dai north of the Zhou Kingdom that was conquered by the Zhao clan of Jin. It was used as the title for the Zhao successor state headed by Zhao Jia, and for one of the Eighteen Kingdoms established by Xiang Yu after the fall of Qin.

The title King or Prince of Dai was subsequently used as an appanage of imperial Chinese dynasties, in reference to the Commandery of Dai that existed from the state of Zhao until the Sui. It was also sometimes used to describe rebellious or independent kingdoms in the same area.
