Áed Dub mac Suibni
King of Ulster
Áed Dub mac Suibni (died c. 588) was an Irish king of the Dál nAraidi in the over-kingdom of Ulaid (in modern Ulster). He may have been king of the Ulaid. Áed was succeeded by his great-nephew Fiachnae mac Báetáin.
Áed Dub — Black Áed — killed the last High King of Ireland to undergo the pre-Christian inauguration ritual, Diarmait mac Cerbaill. Tradition has Diarmaid die a mythic threefold death, and some version make Áed Diarmaid's foster-son. The Annals of Tigernach report, more prosaically, that Diarmaid was killed by Áed Dub in 565 at Ráith Bec, on the plain of Mag Line (Moylinny, near Larne), in the lands of the Dál nAraidi.
