Munster Succession
Archived: 26 September 2026
Abstract
In 1194, Domnall Mór Ua Briain’s death destabilised Munster, where his son Muirchertach’s accession was undermined by capture and blinding, while other Ua Briain and Mac Carthaig kin suffered killings, raids and betrayal. Ecclesiastical authority featured in the death of Killaloe’s bishop and the killing at Cashel despite legatine protection. Elsewhere, resistance expelled foreigners from Uí Fhinntain, Cú Mide Ua Flainn was killed, and Gillibert Mac Goisdelb’s Erne expedition failed. Across the Irish Sea, Richard I’s defeat of John enabled Walter de Lacy to regain Meath, demonstrating how Angevin politics reshaped Irish lordships amid local conflict, rivalry and uncertain authority.
