Henry II of England arrives in Ireland;[1] Irish bishops and most Irish kings submit to his rule.[1]
Ascall mac Ragnaill, last Norse–GaelicKing of Dublin, is captured while trying to retake Dublin from de Clare, perhaps in company with Sweyn Asleifsson, and beheaded; before the end of the year, de Clare relinquishes possession of the city to his own liege lord, Henry.
