Muirchertach Mac Lochlainn

Muircheartach Mac Lochlainn (old spelling: Muirchertach Mac Lochlainn) was king of the Cenél nEógain, Tyrone and High King of Ireland from around 1156 until his death in 1166, He succeeded Toirdhealbhach Ua Conchobhair who died in 1156.

Mac Lochlainn survived an attempt by Ruaidrí Ua Conchobair to unseat him in 1159. He failed, however, to overcome the resistance of the Cenél Conaill and the Ulaid. In 1166, to attempt to achieve a diplomatic settlement with his neighbours, Mac Lochlainn arranged a truce and took hostages from many of the families in Ulster. In return he had given a solemn oath to the Bishop of Armagh and many other notables for his good behaviour. In violation of the oath, he had Eochaid mac Con Ulad Mac Duinn Sléibe, King of Ulster, seized and blinded.

Mac Lochlainn's allies abandoned him almost at once, and he was reduced to a handful of followers. With sixteen of these closest associates, he was killed and his death attributed to the vengeance of Saint Patrick.
