 Máel Gualae mac Donngaile of Munster and Cerball both consented to the change which was little loss to the Eóganachta who had but rarely exercised any control over Osraige.Máel Sechnaill's successes raised more opposition from his Uí Néill kinsmen than from subject kings or the Norse and Norse-Gaels, and the latter part of his reign was spent in conflict with the northern Uí Neill, led by Áed Findliath, son of Niall Caille.In 860 Máel Sechnaill led an army raised from Munster, Leinster and Connacht against the northern Uí Néill.
