Source-derived summary

Lü Guang (Chinese: 呂光; 337 – c.January 400), courtesy name Shiming (世明), also known by his posthumous name as Emperor Yiwu of Later Liang (後涼懿武帝), was the founding emperor of the Di-led Chinese Later Liang dynasty (although during most of his reign, he used the title "Heavenly King"). He was initially a Former Qin general, but in light of Former Qin's collapse starting in 384, he decided to found his own state, initially including nearly all of modern Gansu. As his reign continued, however, his domain dwindled after Southern Liang and Northern Liang declared independence. His death in early 400 left Later Liang in an unstable state, and it would be no more by 403.

Early life and career as Former Qin general

Lü Guang was ethnically Di (although he claimed ancestry from an ethnically Han man named Lü Wenhe (呂文和) who fled from Pei County (in modern Xuzhou, Jiangsu, the same county that Han dynasty emperors' ancestors came) from a disaster and who settled in Di lands). He was born in 337, when his father Lü Polou (呂婆樓) was a follower of the Di chieftain and Later Zhao general Pu Hong (蒲洪, who later changed his family name from Pu to Fu). Eventually, after Fu Hong's son Fu Jiàn founded Former Qin, Lü Polou served on the staff of Fu Jiàn's nephew Fu Jiān (notice different tone) the Prince of Donghai. After Fu Jiān overthrew Fu Jiàn's violent and capricious son and successor Fu Sheng in 357, Fu Jiān claimed the throne and made Lü Polou one of his senior advisors. Lü Guang, however, was not well regarded by his father's colleagues, because he did not study much and instead concentrated his efforts on hunting and riding. However, Fu Jiān's prime minister Wang Meng valued him and persuaded Fu Jiān to make him a general.

Editorial summary

“Lü Guang” enters the record as emperor of Later Liang. Crown Archives preserves that source wording while asking what Guang, emperor and Later can confirm, complicate or overturn.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 306-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 0337-01-01. Its strongest next move is a source search built around Guang, emperor and Later.
Editorial analysis

Why this record matters

“Lü Guang” is worth following because a concise public description often conceals a longer documentary argument. Here, Guang, emperor and Later provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 11, 2026. The linked authority identifier is Q1069762. VIAF identifies the subject as 222803657. None of the 2 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
