The Battle of Islandbridge, also called the Battle of Áth Cliath, took place on 14 September 919, between a coalition of native Irish, led by Niall Glúndub, overking of the Northern Uí Néill and High King of Ireland, and the Dublin-based Vikings of the Uí Ímair, led by Sitric Cáech. It was one in a series of battles initiated by the native Irish to attempt to drive the Vikings of the Uí Ímair from Ireland. The battle was a decisive victory for Sitric Cáech and the Uí Ímair, with Niall Glúndub and five other Irish kings dying in the battle.
