Abstract
A King Killed in Leinster The decisive Irish event conventionally placed in 956 was the killing of Congalach Cnogba, king of Ireland, at Tech Giurann in Leinster. The Annals of Ulster name his attackers as the foreigners of Áth Cliath—Dublin—and the Laigin, or Leinstermen; they also record the death of Áed son of Aichid, king of Tethbae, and “many others”. Chronicon Scotorum makes the disaster still more explicit: Congalach fell with his royal household, and names Matudán son of Áed son of Máel-mithig and Cormac son of Cathalán, king of Fir Arda, among the dead. This was not a routine
