Cluain Immorrais and Carnfree
Archived: 21 October 2026
In 1406, Ireland’s fragmented political order was shaped by disease, warfare, ritual and succession. Plague killed several Leinster men eligible for lordship, potentially affecting dynastic calculations. In Offaly, Murchadh Ó Conchobhair Fáilghe defeated a mixed Meath, Connacht and mercenary force at Cluain Immorrais, inflicting heavy losses and capturing the prestigious Buacach Phádraig relic. In Connacht, Toirdhealbhach Óg Ó Conchobhair Donn, joint king for twenty-two years, was killed by rivals and Burke allies, prompting Cathal Ó Conchobhair Donn’s inauguration at Carnfree around year’s end. Dublin retained limited military and civic capacity, while elite deaths and monastic burials underscored lordship’s religious networks.
