 Widely regarded as the most powerful Irish king of the first half of the 8th century, and the strongest (historical) king from Munster before Brian Bóruma, Cathal mac Finguine is believed to be the last king mentioned in the "Baile Chuinn Chétchathaig".The most expansionist historical Eóganacht king before him was Faílbe Flann mac Áedo Duib (d. 639).The Eóganachta kingship, which had its chief seat at Cashel and chief church at Emly, was the most powerful in the southern half of Ireland, while the various branches of the Uí Néill and Connachta dominated the northern half.
