Disputed Succession
Archived: 3 November 2026
Abstract
In 643, Irish annals recorded disputed succession after the death of Domnall mac Áedo, a prominent northern Uí Néill ruler. Sources variously named his nephews Cellach and Conall Cáel as successors or described shared authority with Diarmait and Blathmac of the southern Uí Néill. Chronological differences place these events around 642–643, but all reflect uncertainty over wider kingship. Regional conflict, including the battle of Cenn Con, demonstrated the independence of Munster dynasties. The death of Bishop Crónán of Naendruim also illustrates the political and economic importance of churches. Ireland remained a network of competing kingdoms, kin groups and ecclesiastical communities.
