Ernak was the last known ruler of the Huns, and the third son of Attila. After Attila's death in AD 453, his Empire crumbled and its remains were ruled by his three sons, Ellac, Dengizich and Ernak. He succeeded his older brother Ellac in AD 454, and probably ruled simultaneously over Huns in dual kingship with his brother Dengizich, but in separate divisions in separate lands.[1]
Priscus, during his stay at Attila's court in AD 448 or 449, recorded a personal occasion between Attila and Ernak. At a banquet Attila looked on him with serene eyes, while taking small account of his other sons.[2] He was Attila's favorite son,[3] because as a certain Hun explained to him, the Hunnic prophets prophesied his genos would fail, but would be restored by this son.[2]
Ernak has often been identified with Irnik from the Nominalia of the Bulgarian khans, who is noted as a descendant of the Dulo clan and leader of the Bulgars for 150 years, starting approximately from AD 437.[3]
