Arklow’s Broken Safe Conduct
Archived: 24 October 2026
Abstract
In 1282, Muirchertach Mac Murchada, king of Leinster, and his brother Art were murdered at Arklow on 21 July while travelling under safe conduct to meet Roger Bigod in England. Evidence links the killing to justiciar Stephen de Fulbourn’s frontier policy, exposing the insecurity of agreements between Gaelic rulers and royal government. Their deaths temporarily weakened Leinster unrest but did not end contested lordship. Annals also record Taichlech Ó Dubhda’s killing, Lasarfina Ó Conchobair’s death, chieftaincies changing hands, and prolonged winter snow. These events reveal Gaelic, Anglo-Irish and royal worlds, while annalistic dating cautions against assigning uncertain conflicts to 1282.
