Abstract
In 916, Flann Sinna died on 25 May after ruling Tara since 879, ending a long southern Uí Néill ascendancy. His son Conchobar succeeded in Mide, while Niall Glúndub of Cenél nÉogain became king of Tara, reflecting dynastic alternation rather than unified monarchy. Niall renewed the neglected Fair of Tailtiu, publicly asserting royal authority and the capacity to organise exchange, obligations and assembly. Elsewhere, raiders from Loch Dá Chae harried Munster and Leinster, killing Ainnle of Uaithne. Deaths among leading ecclesiastics and a lightning fire at Armagh exposed institutional vulnerability amid ceremony, rivalry and Scandinavian pressure throughout much of Ireland.

Abstract
In 915, Ireland experienced interconnected political, religious and military pressures rather than a decisive battle. Óengus, Flann Sinna’s designated heir, died, weakening the ageing king of Tara, while Domnall of Ailech died in penitence, confirming his half-brother Niall Glúndub’s northern prominence. Flann’s sons Donnchad and Conchobor rebelled in Mide, but Niall’s army secured their submission and a truce with Brega, enhancing his influence. Scandinavian forces based at Waterford Harbour plundered Munster churches and settlements. Deaths of leading clerics and the treacherous wounding of a local king reveal institutional and regional instability. The year foreshadowed later succession conflicts and Viking warfare.

Abstract
In 912, Irish annals centre on Cernachán son of Duiligén, who removed a captive from Armagh’s sanctuary and who was then killed at Loch Cerr. Niall son of Áed, king of Ailech, drowned Cernachán there, asserting Patrick’s church protection and northern Uí Néill authority. The episode reveals sanctuary, kinship and violence within fragmented kingship. Nearby notices record Niall’s campaigning, conflict between Brega and Leinster, clerical deaths and an accidental fire at Armagh. Annals also describe wet, dark weather and an appearance of Halley’s Comet. Maritime entries show Ulaid fleets, Welsh captives, ransom networks and Scandinavian activity across the Irish Sea.
