Kavhan Dometian

During the reigns of Tsar Samuel, 997–1014, and Tsar Gavril Radomir, 1014–1015, Kavhan Dometian was an important figure in Bulgarian government. Although information about him is limited, the Byzantine chronicler John Skylitzes calls him a 'symparedros', which can be translated as a 'partner' in the tsar's authority.

Like his predecessors—Iratais under Kan Krum, Isbul under Kan Omurtag and Theodore Sigritsa under Tsar Simeon the Great—Dometian led major military campaigns. In spring 1015, he headed a counter-offensive in the region of Voden, now Edessa in Greece, and Moglena. This campaign was crucial, as he faced the Byzantine emperor Basil II himself, clearly demonstrating its importance.

During the campaign, the Byzantines besieged Moglena Fortress, whose ruins can still be seen today. According to Skylitzes, the emperor undermined the walls and burned timber and other combustible materials in the trenches, bringing about the fortress's fall. The inhabitants of Moglena under Voivode Ilitsa and the 'mighty Dometian' were forced to surrender.

The captured Bulgarian soldiers were not blinded, as had happened a year earlier at Kleidion, but were resettled in the Byzantine Empire's Armenian and Georgian territories. After this campaign, Dometian was removed and isolated from Bulgaria, and his subsequent fate is unknown.
