Umor of Bulgaria
（重定向自Umor）
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.
