Tuatha Dé Danann
His father is variously listed as Aengus or Ogma of the Tuatha Dé Danann or Elatha of the Fomorians, and his mother was Ethniu of the Fomorians. He succeeded his grandfather Eochaid Ollathair (“the Dagda”) as High King of Ireland. Delbáeth ruled the united Tuatha Dé Danann and Fomorians for ten years, before dying at the hand of his son, Fiacha.
