He was the founder of the O'Brien dynasty, and is widely regarded as one of the most successful and unifying monarchs in medieval Ireland.

The Abbot of Clonard was the monastic head of Clonard Abbey, which is in modern-day County Meath, Ireland. The abbey was founded by Saint Finnian in the early sixth century. After the death of Saint Finnian, the abbots bore the title "Comarbai Finnéin". However, the title was ambiguous, since it may refer to the abbots of Moville, County Down, founded by Finnian nepos Fiatach. The abbots of Clonard were sometimes called 'coarbs of Finnian and Mo Cholmóc'. Until the early twelfth century, a few of the abbots and some others at Clonard Abbey were consecrated bishops, but this did not necessarily mean they were bishops of Clonard, since the diocese of Clonard was not established until the Synod of Rathbreasail in 1111.
