Muirchertach mac Néill (died 26 February 943), called Muirchertach of the Leather Cloaks (Old Irish: Muirchertach na Cochall Craicinn), King of Ailech.

Family ramifications[edit]

Muirchertach belonged to the Cenél nEógain sept of the northern Uí Néill. He was the son of Niall Glúndub and Gormlaith, thus his father and both of his grandfathers—Niall's father Áed Finnliath and Gormlaith's father Flann Sinna—had been High King of Ireland. Máel Muire ingen Cináeda (died 913), his father's mother, had after the death of Áed been married to Flann Sinna, and had borne him Domnall (died 921) and Liagnach (died 932). She was a daughter of king of the Picts, Cináed mac Ailpín.

Early life[edit]

Muirchertach's father was killed in battle against the Norse-Gaels of Ireland near Dublin on 14 September 919 along with many other Irish kings. Muirchertach's mother's brother, Donnchad Donn mac Flainn, became the new High King, while Muirchertach became King of Ailech.

Career[edit]

Muirchertach married Donnchad's daughter Flann, but relations between the two men were not good. Conflict between them is recorded in 927, 929, and 938, but it was not until 941, following Flann's death the year previously, that Muirchertach and Donnchad came to blows. That year Muirchertach raided Mide, Osraige, and Munster, taking the Munster king Cellachán Caisil hostage as a demonstration of his power and Donnchad's limited authority.

Muirchertach was a hardened warrior, and finally met his death in battle in 943 at the hands of Blácaire mac Gofrith, King of Dublin. His obituary in the Annals of Ulster calls him "the Hector of the western world", and the "heir designate of Ireland".

Muirchertach's son Domnall ua Néill was passed over for the succession on Donnchad Donn's death the year after Muirchertach's, but eventually became High King following the death of Donnchad's successor Congalach Cnogba in 956.
