<human>:  I have a question about Irish history. What year was the Battle of Clontarf?
<bot>: The Battle of Clontarf took place in 1014. It was a battle between the forces of the High King of Ireland, Brian Boru, and the forces of the Viking king, Máel Sechnaill mac Máele Ruanaid. The battle was a decisive victory for the Irish forces, and it marked the end of Viking rule in Ireland.
