Cill Mór’s Burning
Archived: 26 October 2026
In 1226, Connacht remained unstable after Cathal Crobderg Ua Conchobair’s death, as his son Áed faced dynastic rivals, neighbouring lords and changing English policy. Killings, attacks on houses, captivity and local feuds across Connacht, Breifne and Iar-Chonnacht exposed fractured authority. Henry III ordered Geoffrey de Marisco to demand Connacht’s surrender from Áed, advancing Richard de Burgh’s interests despite opposition among colonial magnates. Cathal Ua Raigillig destroyed Cill Mór castle, illustrating the vulnerability of frontier strongholds. Deaths of bishops, nobles and Cong’s learned erenagh also marked the year, while religious houses preserved learning, patronage and dynastic commemoration amid wider ongoing conflict.
