Octar

Octar ruled the Huns jointly with his brother Rugila, sharing leadership of the Hun confederation. This co-rulership helped consolidate Hun power and laid the groundwork for the later unification under Rugila's sole rule.

Octar led a Hun campaign against the Burgundians, a Germanic tribe on the Rhine. The campaign resulted in a Hun victory, weakening the Burgundians and expanding Hun influence into the region. This event is sometimes linked to the later Nibelungenlied legends.

Octar died during the campaign against the Burgundians, reportedly from overeating or gluttony. His death left Rugila as the sole ruler of the Huns, allowing Rugila to further unify and strengthen the Hun confederation.
