 The other part of Ailech, Cenél Conaill became known as Tír Conaill, the land of Conall, Anglicised as Tyrconnell.Following the Norman invasion of Ulster in 1177, Tír Eoghain had become the predominant power in the north of Ireland, a position it regained upon the collapse of the Norman Earldom of Ulster in the 14th century.During the reign of Tudor monarch Elizabeth I it would become an earldom within the kingdom of Ireland, however the extent and power of Tyrone would be eventually curtailed and it was shired into the counties of Armagh and Tyrone, and subdivided into baronies.
