Ernak was the last known ruler of the Huns, and the third son of Attila. After Attila's death in 453 AD, his Empire crumbled and its remains were ruled by his three sons, Ellac, Dengizich and Ernak. He succeeded his older brother Ellac in 454 AD, and probably ruled simultaneously over Huns in dual kingship with his brother Dengizich, but in separate divisions in separate lands. 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 437 AD.
