Emperor Xiaowu of Jin (; 362–396), personal name
Sima Yao (司馬曜),
courtesy name Changming (昌明), was an emperor of the Eastern
Jin Dynasty (265–420) in
China. During his reign, Jin saw his dynasty survive a major attempt by
Former Qin to destroy it, but he would nevertheless be the last Jin emperor to actually exercise imperial power, as his sons
Emperor An and
Emperor Gong would be controlled by
regents and warlords. He himself died an unusual death—he was killed by his
concubine Consort Zhang after he insulted her.
