A Church Already Changing; Ireland, the Cistercians and the Norman Arrival

Tracing the Irish-led reform movement from synods of Cashel, Ráith Bressail & Kells through work of Cellach, Gillebert & Malachy of Armagh. When Anglo-Norman forces arrived in Ireland, they encountered not an unreformed Church, but one already undergoing profound change. This talk traces the Irish-led reform movement from the synods of Cashel, Ráith Bressail and Kells through the work of Cellach, Gillebert and Malachy of Armagh. It explores the creation of territorial dioceses, metropolitan provinces, new clerical ideals and changing relationships between Church, kingship and ordinary Christian life. Particular attention is given to the Cistercians: from Clairvaux and Mellifont to the pre-invasion foundations of Baltinglass, Jerpoint and Killenny. The final section considers how Norman conquest redirected existing reform through new patrons, lordships and cross-channel networks, culminating at Tintern de Voto. Set within Tintern Abbey itself, the lecture reveals how reform, conquest and patronage reshaped Ireland’s institutions, communities and physical landscape.
