War, Truce and Murrain
Archived: 26 September 2026
Abstract
In 1133, Toirdelbach Ua Conchobair’s disputed high-kingship faced a Munster invasion of Connacht, which killed an heir but secured no submission. He later agreed a year’s truce with Conchobar Ua Briain, while Mide and Bréifne destroyed his Athlone bridge and fort. Feuds in Mide, Leinster and Fine Gall brought assassinations, reprisals, raids and the burning of Lusk church. Regional conflicts, deaths and accidents continued. Armagh’s succession remained divided between reformer Malachy and Muirchertach mac Domnaill. Clerical visits, learned figures and burnings featured in the annals. A devastating cattle and pig murrain damaged Ireland’s economy; an August solar eclipse was recorded.
