Murong Bao
Murong Bao (355–398), courtesy name Daoyou (道佑),
Xianbei name Kugou (庫勾),
formally Emperor Huimin of (Later) Yan ((後)燕惠愍帝), temple name Liezong
(烈宗) or Liezu (烈祖), was an emperor of the Chinese/Xianbei state Later Yan.
He inherited from his father Murong Chui (Emperor Wucheng) a sizable empire but lost most of it within a span of a year, and would be dead in less than three, a victim of a rebellion by his granduncle Lan Han.
Historians largely attributed this to his irresolution and inability to judge military and political decisions.
While Later Yan would last for one more decade after his death, it would never regain the power it had under Murong Chui.

Empress Duan (段皇后, personal name unknown) (died 400), formally Empress Huide (惠德皇后, literally 'the benevolent and virtuous empress'), was an empress of the Chinese/Xianbei state Later Yan.
Her husband was Murong Bao (Emperor Huimin).
Based on her family name, Empress Duan was probably from the same Duan tribe royal line that a number of Former Yan and Later Yan empresses and imperial consorts came from.
Murong Bao created her empress in 396 after he became emperor.
Little is known about her life during the next few years, when Murong Bao saw his empire collapse in light of attacks by Northern Wei and internal rebellions, and he was killed in a rebellion by Lan Han in 398, along with her son Murong Ce (慕容策)
the crown prince.
Lan spared her, however, and after Murong Bao's son by his concubine Consort Ding, Murong Sheng, killed Lan and became emperor, he honored her as empress dowager.
She died in early 400.
