The Kings of Ulster and their territorial Dominion

To the overlordship which we have seen the O’Neills had obtained over clans outside of Tir Eoghain was now added a supremacy over nearly all the country east of the Bann. They now adopt the title of ” King of Ulster ” to indicate their leadership over all the north. The name of the Norman earldom is utilised to support a claim to a territorial dominion outside the old Kingdom of ” Aileach.” It is significant also that the names of the territories ” Tir Eoghain ” and ” Tir Chonaill” are now used instead of the ancient names ” Cineal Eoghain ” and ” Cineal Chonaill,” which embodied the idea of kinship rather than of territory.
