A member of the Ó Conchobhair family, Áed ascended to the throne after King Art of Connacht was killed by the Cinel Conaill in 1046.
In December 1061, Áed survived an invasion from a branch of the Uí Briúin dynasty (namely the Síl Cellaigh) which led to the expulsion of the branch to Iar Connacht.
The Muintir Murchadha invaded Loch Oirbsean, and deposed Aedh Ua Conchobhair.
The victory of Gleann-Phadraig was gained by Aedh Ua Conchobhair over the people of West Connacht, where many were slain, together with Ruaidhrí.
Ó Flaithbheartaigh, lord of West Connacht, was beheaded, and his head was carried to Cruachain in Connacht, after the son of Aedh, son of Ruaidhri, had been defeated.
