Tailtiu Renewed

Archived: 27 October 2026

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.

Niall’s Meath Settlement

Archived: 27 October 2026

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.
