Rival Kingships
Archived: 26 September 2026
In 1201, Ireland experienced interconnected struggles for kingship, lordship and ecclesiastical authority. In Connacht, Cathal Crobderg Ua Conchobair, aided by northern rulers and John de Courcy, failed to dislodge his kinsman Cathal Carrach, who received William de Burgh’s support. De Courcy’s subsequent defeat near Kilmacduagh and arrest by the de Lacys revealed rivalries among Anglo-Norman magnates. Ulster saw the killing of Ruaidhrí Mac Duinnsléibe and dynastic change in Cenél nEógain. In Munster, de Burgh campaigned with Ua Briain princes before churchmen mediated peace. King John redistributed lordships, while episcopal deaths and papal activity heightened institutional uncertainty. Conflict remained unresolved thereafter.
