Battle of Clontarf: Clan O' Brien and MacDomnaill

clipped from generation13.com In North Ireland, Malachy the Second followed Boru's lead when his forces defeated a Norse army to take Dublin in 980 and Malachy became King of Meath. Boru was granted the title "Ard Ri", meaning "High King". In 1013, Maelmordha, King of Leinster, revolted and allied with the Vikings. They summoned reinforcements from Boru's other Irish rivals and the Viking nations, as far away as Normandy and Iceland. The two forces met on Good Friday, 1014 at Clontarf.
