Rothechtaid, son of Maen, son of ÃÂengus Olmucaid, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He came to power by killing the previous incumbent, his grandfather's killer ÃÂnna Airgdech, in the battle of Raigne. He ruled for twenty-two years. The Lebor Gabála ÃÂrenn gives two versions of his death. In one version, he was killed in single combat in Cruachan by Sétna Airt, who fought to protect his son FÃÂachu FÃÂnscothach. In the other version, he died of his wounds in Tara. The chronology of Geoffrey Keating's Foras Feasa ar ÃÂirinn dates his reign to 1005âÂÂ980 BC, that of the Annals of the Four Masters to 1383âÂÂ1358 BC.
His son was Demal mac Rothechtaid.
