Prince or King of Dai was an ancient and medieval Chinese title.
Tuoba Shiyijian was the last prince of the Xianbei-led Dai dynasty of China and ruled from 338 to 376 when Dai was conquered by the Former Qin dynasty. He was the son of Tuoba Yulü and the younger brother of Tuoba Yihuai, whom he succeeded in 338. In 340 he moved the capital to Shengle (盛樂). His grandson Tuoba Gui later founded the Northern Wei dynasty and accorded him the posthumous name Emperor Zhaocheng (昭成皇帝) and the temple name Gaozu (高祖).
Tuoba Yulü ruled as prince of the Tuoba Dai 316 to 321.
Tuoba Heru ruled as prince of the Tuoba Dai 321 to 325. He was the son of Tuoba Yituo, and the brother of Tuoba Pugen and Tuoba Hena. In 321, when his cousin Tuoba Yulü was the Prince of Dai, Heru's mother, Lady Qi, launched a coup d'état against his cousin, killing Tuoba Yulü. She then installed Heru as the new Prince of Dai, but as he was still young at the time, actual power fell to his mother. He only began to personally rule in 324, but would die by the end of 325. He was succeeded by Tuoba Hena.
Lady Qi, also known as Lady Wei (惟氏), was the wife of Tuoba Yituo and a regent of Dai in the Sixteen Kingdoms period during the minority of her son between 321 and 324. As the rulers of Dai were posthumously honoured as emperors during the Northern Wei, she is also referred to as Empress Dowager Qi (皇后祁) or Empress Dowager Wei (皇后惟) in some historical records.
Tuoba Hena ruled as prince of the Tuoba Dai from 325 to 329 and again from 335 to 337. He was the youngest son of Tuoba Yituo and brother of his predecessor, Tuoba Heru.
