King of the Tuatha Dé in the Otherworld
Bodb Derg — “Bodb the Red” — was elected king of the Tuatha Dé Danann after they withdrew into the síde, the Otherworld mounds beneath Ireland’s hills. He was the son of the Dagda and the king who kept the divine world running after the age of great battles was over.
He ruled from Síde ar Femen, the Otherworld mound beneath Slievenamon — a distinctive rounded hill in County Tipperary visible for miles across the plain of Munster. His kingship was earned, not inherited. The Tuatha Dé elected him by vote. lir contested the result and refused to accept it. Bodb offered his daughter Aobh to lir in marriage as a peace offering — and that gesture set the tragedy of the swan-children in motion – children of lir.
Both the beloved mother (Aobh) and the jealous stepmother (Aoife) who transformed the children into swans were Bodb’s daughters. His own family was the source of both the love and the curse. When he discovered what Aoife had done, he condemned her to become a demon of the air for all time. Then he spent 900 years unable to undo what she had created.
His power is not in combat or magic — it is in knowledge and rightful authority. He is the Otherworld’s administrator. He knows where every significant being in the supernatural world is located, and his permission is needed to navigate it. When Óengus Mac Óg needed to find the woman who came to him only in dreams, he came to Bodb — and Bodb searched every territory under his control until he found her.
His epithet “the Red” — Derg — refers to red hair, which in Irish culture marked someone as touched by the supernatural.
