Tervel of Bulgaria

Tervel of Bulgaria, also known as Tarvel or Terval, was a prominent ruler during the early years of the First Bulgarian Empire in the eighth century. His reign marked a significant period in Bulgarian history, particularly noted for his military prowess and diplomatic relations with the Byzantine Empire.

In the year seven hundred and five, Tervel was honored by Emperor Justinian II with the title of caesar, making him the first foreigner to receive such a distinction. This recognition underscored his importance in the region and his influence over the political landscape of the time.

Raised in the traditions of paganism, much like his grandfather Khan Kubrat, Tervel's faith evolved, and he was possibly baptized by Byzantine clergy, reflecting the complex interplay of cultures during his rule. His leadership was pivotal during the siege of Constantinople from seven hundred and seventeen to seven hundred and eighteen, where he played a crucial role in repelling Arab forces.

According to the Nominalia of the Bulgarian khans, Tervel belonged to the esteemed Dulo clan and reigned for a remarkable twenty-one years. Historical accounts and traditions suggest that he was the son of Asparukh, further solidifying his lineage and legacy within the Bulgarian khanate.
