Pseudo-historians list 84 kings of Ireland prior to the formation of the Pentarchy. When this mythical kingship was interrupted is a matter of dispute. The Annals of Tigernach state that Ireland was divided into the five upon the slaying of Conaire Mór, however it is suggested alternatively that it happened upon the death of Conaire's father, Eterscél Mór, the 84th king of Ireland. Keating however suggests it occurred in the reign of Eochu Feidlech who was the 82nd king of Ireland.
