Frontiers Under Pressure
By 1178, English lordship in Ireland remained limited to Dublin, parts of Leinster and eastern Meath, while Gaelic kings retained most territories amid rivalries and shifting alliances. Hugh de Lacy raided Clonmacnoise and the midlands, but Connacht resistance constrained him. John de Courcy suffered heavy defeats during northern raids, showing Anglo-Norman arms were vulnerable to terrain, ambushes and supply problems. Warfare across Connacht and Munster damaged settlements, churches and livestock. Dynastic conflicts, ecclesiastical deaths, monastic foundations and learned culture continued alongside violence. Annals also recorded wind damage at Derry and the drying of the River Galway, as conquest remained undecided.
