Domnall Midi

Domhnall Mac Murchada (died 20 November 763), called Domnall Midi (Donald of Meath), was High King of Ireland. He belonged to the Clann Cholmáin branch of the Uí Néill. Clann Cholmáin's pre-eminence among the southern Uí Néill, which would last until the rise of Brian Bóruma and the end of the Uí Néill dominance in Ireland, dates from his lifetime.
