Cathair Mór

Cathair Mór ("the great"), son of Feidhlimidh Fiorurghlas, a descendant of Conchobar Abradruad, was, according to Lebor Gabála Érenn, a High King of Ireland. He took power after the death of Fedlimid Rechtmar. Cathair ruled for three years, at the end of which he was killed by the Luaigne of Tara, led by Conn Cétchathach. The Lebor Gabála Érenn synchronises his reign with that of the Roman emperor Marcus Aurelius (161–180). The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to 113–116, that of the Annals of the Four Masters to 119–122.
