Conaire Mór (the great), son of Eterscél, was, according to mediaeval Irish legend and historical tradition, a High King of Ireland sometime during the 1st century BC or 1st century AD. His mother was Mess Búachalla, who was either the daughter of Eochu Feidlech and Étaín, or of Eochu Airem and his daughter by Étaín. In the Old Irish saga Togail Bruidne Dá Derga he is conceived when his mother is visited by Nemglan who flies in her skylight in the form of a bird, and is brought up as Eterscél's son.
According to the Lebor Gabála Érenn, he took power after killing his predecessor, and his father's killer, Nuadu Necht. In Togail Bruidne Dá Derga he succeeds Eterscél directly. When Eterscél dies, a bull-feast is held. A bull is killed, a man eats his fill of its meat and drinks its broth, and sleeps as incantations are chanted over him. Whoever this man sees in his sleep will be the new king. He sees a naked man coming along the road to Tara with a stone in his sling. The young Conaire, meanwhile, is hunting birds in his chariot. He chases them into the sea, where they become armed men, announce themselves as Conaire's father's bird troop, and inform him that it is forbidden for him to hunt birds. The leader of the bird troop is called Nemglan and he tells Conaire to go naked to Tara, where he will be made king, and places several geasa (taboos) on his reign. Among other things, he may not be preceded by three red men into the house of a red man. As he approaches Tara he is met by three kings carrying clothes for him, and when he arrives he is made king.
