Faildergdóit
High King of Irelad

Faildergdóit (later spelled Faildeargdoid or Ailldeargoid), son of Muinemón, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He succeeded to the throne on the death of his father. He is said to have been the first king in Ireland whose subjects wore gold rings (Old Irish failge) on their hands. He ruled for ten years before being killed, either by Sírna mac Déin, or by his successor Ollom Fotla, whose father, Fíachu Fínscothach, had been killed by Failderdóit's father Muinemón.

Why this record matters
The phrase “high King of Irelad” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jan 23, 2023. The linked authority identifier is Q1270848. None of the 0 selected statements returned an explicit reference.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
