Connacht Under Siege
Archived: 26 September 2026
In 1067, Leinster, Munster, Osraige and Hiberno-Norse Dublin invaded Connacht, reflecting volatile alliances among Irish rulers. Connacht’s king, Áed Ua Conchobair, initially ambushed the coalition, but was killed about a week later at Turloch Adhnach by Áed Ua Ruairc’s Bréifne army. Ua Ruairc seized Connacht’s kingship, though the Ua Conchobair dynasty later recovered. Annals differ in detail but confirm the campaign’s sequence and significance. Other violence included dynastic killings and blinding in Munster. Kildare’s church burned, while ecclesiastical leaders and poet Murchad Ua Carthaig died. The year exposed political rivalry, military burdens, and enduring religious, learned and economic institutions alike.
