Sevar, khan of Bulgaria

Sevar of Bulgaria https://en.wikipedia.org/wiki/Sevar_of_Bulgaria "Sevar (Bulgarian: Севар) was a ruler of Bulgaria in the 8th century.

The Nominalia of the Bulgarian khans, which states that he belonged to the royal Dulo clan and ruled for 15 years. According to the chronology developed by Moskov, Sevar would have reigned 721–737. Other chronologies place his reign in 738–754, but cannot be reconciled with the testimony of the "Namelist". According to historians he is the last ruler of the Dulo dynasty.

It has been suggested that his name is derived from Persian Ziwar (adornment).[1] Although initially a female name, it could also serve as a component of male names, as suggested by Chuvash pre-Christian name Aksĕver.

It is possible that his reign was peaceful, because the Byzantine chronicles do not report any events on the Empire’s northern borders from that period. Although this is an argument from silence, it is a plausible assumption. Sevar Point on Livingston Island in the South Shetland Islands, Antarctica is named after Sevar of Bulgaria."
