Clonfert Truce
Archived: 26 September 2026
In 1190, Ireland’s politics combined dynastic conflict, local warfare, diplomacy and religious patronage. In Connacht, Cathal Crobderg and Cathal Carrach Ua Conchobair negotiated an inconclusive truce at Clonfert, mediated by churchmen, before a storm on Lough Ree drowned Cathal Crobderg’s son and leading followers. Rival branches of the dynasty remained violent. In Desmond, Domnall mac Carthaig defeated foreign raiders, recovered their spoil and secured peace with Domnall Mór Ua Briain of Thomond. Foundations or endowments at Knockmoy and possibly Killone demonstrated rulers’ religious and political ambitions. Anglo-Norman lordships expanded, but Gaelic rulers and institutions remained decisive across much of Ireland.
