Umor of Bulgaria
Bulgarian ruler
Umor (Bulgarian: Умор) was the ruler of Bulgaria in 766.
According to the Namelist of Bulgarian Rulers, Umor reigned for only 40 days in 766 and belonged to the Ukil clan, which makes him a relative of the former rulers Vinekh and possibly Kormisosh. The Byzantine sources indicate that his predecessor Sabin entrusted Bulgaria to Umor, but give no details of his short reign or fate. Some scholars speculate that he was a champion of the peace party like his discredited predecessor, and that he may have likewise fled to the Byzantine Empire.
The 17th century Volga Bulgar compilation Ja'far Tarikh (a work of disputed authenticity) represents Yumart (i.e., Umor) as the elderly father-in-law of the former ruler Teles (i.e., Telets). According to this source Yumart deposed Sain (i.e., Sabin) and died shortly afterwards.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Umor of Bulgaria”, the useful work is to connect “bulgarian ruler” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 11, 2026. The linked authority identifier is Q928307. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1988, 1999 and 1997.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
