Emperor Jianwen
In summer 372, Emperor Jianwen grew ill, and repeatedly tried to summon Huan to the capital—perhaps to offer him the throne—but Huan, concerned that it was a trap, continuously declined. Emperor Jianwen soon died, and was succeeded by his 10-year-old son Sima Yao, whom he created crown prince right before his death. As Huan himself died in early 373, the threats of a Huan usurpation dissipated, and Jin continued for several decades longer.
