About Murong Wei

Murong Wei, courtesy name Jingmao (景茂), also known by his Southern Yan-accorded posthumous name as the Emperor You of Former Yan (前燕幽帝), was the last emperor of the Xianbei-led Chinese Former Yan dynasty. He became emperor at age 10 and, late in his reign, with powers in the hands of his mother Empress Dowager Kezuhun and his incompetent and corrupt granduncle Murong Ping, was captured by Former Qin's prime minister Wang Meng in 370, ending Former Yan. Later, during the middle of Former Qin's collapse after its defeat at the Battle of Fei River in 383, he tried to join his brother Murong Chong in rebellion and was executed by Emperor Xuanzhao of Former Qin in early 385.
