Mid-9th-century bishop-king of Munster who sought to become the ruler of all of Ireland. Early in his kingship he interfered with the successions at such distant ecclesiastical centres as Armagh and Clonmacnoise, the latter of which he sacked. On the secular front he did battle with the powerful Uí Maine and Uí Néill families. Before there was a paramount ruler of all of Ireland, he obtained the submission of a king of Tara, Niall Caille, and two years later seized Niall's queen, Gormlaith (2), and her female retainers. Modern commentators have suggested that taking the king of Tara's mortal spouse implies possession of his other spouse, i.e. the sovereignty of Ireland. Possibly identical with Fedlimid (1).
