  • Alfonso II of Aragon conquers Caspe and Teruel.
  • Henry II of England invades Ireland with the aid of the ousted King of Leinster, Diarmait Mac Murchada (dies May 1). As is usual at this time, Henry commandeers merchant ships as part of his invasion. Henry claims the ports of Dublin, Waterford, and Wexford for himself and promises the Irish chieftains protection if they will acknowledge him as their overlord. This begins eight centuries of conflict between Ireland and England. Ascall mac Ragnaill, last Norse–Gaelic King of Dublin, is captured while trying to retake Dublin from the Cambro-Norman Richard de Clare (Strongbow), 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. Ireland would be enslaved for the next 700 years.
