Walter de Burgh’s Last Summer
Archived: 25 October 2026
Abstract
Walter de Burgh, earl of Ulster and lord of Connacht, died at Galway in July 1271, leaving his young heir Richard vulnerable during a minority. His death coincided with Áed mac Fedlimid Ó Conchobair’s destruction of castles at Templehouse, Sligo and Athleague, weakening de Burgh authority across Connacht. Killings in Connacht, Annaly, Oriel and the Breifne borderlands further revealed fragmented lordship and shifting local alliances. Annalistic notices also record religious deaths, penitence and burial, reflecting political and spiritual culture. Although Anglo-Norman power endured, 1271 reduced its capacity while Áed’s Gaelic kingship remained formidable, making the year a significant turning point.
