代王
The Jin Dynasty had developed an alliance with the Tuoba against the Xiongnu state Han Zhao. In 315 the Tuoba chief was granted the title of the Prince of Dai. After the death of its founding prince, Tuoba Yilu, however, the Dai state stagnated and largely remained a partial ally and a partial tributary state to Later Zhao and Former Yan, finally falling to Former Qin in 376.
