Murong Wei (Chinese: 慕容暐; 350 – 385) was the last emperor of the Xianbei-led Former Yan dynasty, a state that existed during the Sixteen Kingdoms period in northern China. He ascended the throne in 355 at the age of five, succeeding his father Murong Jun, and ruled (under regency) until the state's conquest by the Former Qin in 370.
Background and accession
Murong Wei was born in 350, the eldest son of Murong Jun (Emperor Jingzhao of Former Yan) and Empress Kezuhun. Following the death of his father in 360, the five‑year‑old Murong Wei was proclaimed emperor, with his mother, Empress Dowager Kezuhun, and the high minister Murong Ke acting as regents. The regency was characterized by internal court intrigue and power struggles among the Murong clan and their Xianbei aristocracy.
Reign
During Murong Wei’s early reign, the state of Former Yan continued its territorial expansion, capturing parts of the Central Plains and consolidating control over the Shanxi region. However, internal dissent grew, particularly between the regent Murong Ke and other nobles. In 360, Murong Ke was killed in a coup led by the general Murong Chui, who later established the Later Yan dynasty. Murong Wei, now an adolescent, assumed personal command of the government, but his authority remained limited.
In 369, the Former Qin, under Emperor Fu Jiān, launched a major campaign against Former Yan. Murong Wei's forces suffered decisive defeats at the Battles of Lucheng and Baizhang, leading to the surrender of the Yan capital, Ye (present‑day Linzhang County, Hebei). In 370, Murong Wei formally submitted to Former Qin, ending the independence of Former Yan. He was granted the title of Prince of Xicheng by Fu Jiān and retained nominal control over a reduced fief.
Later life and death
After the surrender, Murong Wei was relocated to the Former Qin capital, Chang’an, where he lived under house arrest. In 385, during the widespread rebellions that culminated in the collapse of Former Qin (most notably the uprising led by the Xianbei general Fu Pi), Murong Wei attempted to escape but was captured and executed by Former Qin authorities. His death marked the definitive end of the Murong lineage's rule over Yan territories.
Legacy
Murong Wei is historically noted as the last ruler of Former Yan and for his role in the transition of power among the Xianbei states during a period of fragmentation known as the Sixteen Kingdoms. His reign illustrates the challenges faced by youthful monarchs under regency and the vulnerability of smaller polities to larger, more centralized powers such as Former Qin. Contemporary Chinese historiography, including the Jin Shu and Zizhi Tongjian, records his reign with emphasis on the political instability and military defeats that preceded the state's annexation.
