Niall Glúndub

Niall Glúndub mac Áeda (died 919) was king of the Cenél nEógain and, from 916, High King of Ireland. A son of Áed Findliath, his mother was Máel Muire, daughter of Kenneth MacAlpin, king of Scots. He succeeded his brother as king of Ailech in 911.

After the high king died in 916 he took the high kingship and revived the Óenach Tailteann gathering. He fought the Norse and fell with twelve chieftains against Sihtric Cáech at the Battle of Islandbridge in 919.
