Castledermot’s First Parliament
Archived: 25 October 2026
On 18 June 1264, an assembly at Castledermot became the earliest securely documented Irish gathering to call itself a parliament. Chaired by the justiciar Richard de la Rochelle, it investigated Dublin archbishops’ claimed criminal jurisdiction against Prince Edward’s rights, illustrating contested authority rather than representation. Meanwhile Walter de Burgh’s war with the FitzGeralds devastated Connacht and exposed weakness in royal administration. Anglo-Irish leaders negotiated peace with Fedlimid Ó Conchobair at Athlone, acknowledging Gaelic power. In Armagh, Archbishop Máel Pátraic Ó Scannail built defences and welcomed Franciscans. Together, these events vividly reveal competing lordly, royal, Gaelic and ecclesiastical powers in Ireland.
