The Battle of Clontarf took place on April 23, 1014 near Dublin between the forces of the High King of Ireland, Brian Boru, and a confederation of Irish and Viking invaders led by the King of Leinster, Máel Mórda. It resulted in a victory for Brian Boru's forces, though Brian himself was killed in the battle. The battle marked the end of Viking domination in Ireland and the establishment of greater authority for the High King over the country.
