Fedlimid Rechtmar (Old Irish: [ˈfʲeðʲlʲimʲiðʲ ˈr͈ʲextṽər]; "the lawful, legitimate" or "the passionate, furious") or Rechtaid ("the judge, lawgiver"),[1] son of Tuathal Techtmar, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
He took power after killing his predecessor, and his father's killer, Mal mac Rochride.
[2] The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to 104–113, that of the Annals of the Four Masters to 110–119.
[3] The Lebor Gabála Érenn synchronises his reign with that of the Roman emperor Marcus Aurelius (161–180).
He ruled for nine or ten years before dying in his bed, and was succeeded by Cathair Mór.
