Munster was divided into three Kingdoms: the Kingdom of Thomond under the O'Brien dynasty, the Kingdom of Desmond under the MacCarthy Mór dynasty, and the Kingdom of Airgíalla under the Kennedys, although the last was short-lived. Muirchertach apparently went into retirement having lost his High Kingship, and died at Lismore, modern County Waterford, a year later in 1119. He was succeeded by Toirdelbach Ua Conchobhair as High King of Ireland, who would prove to be one of the greatest High Kings in the history of Ireland. Although the O'Briens never reclaimed the High Kingship, the Kingdom of Thomond remained a powerful kingdom for the next few centuries.
