Source-derived summary

Eochu Fíadmuine was, according to medieval Irish legend and historical tradition, joint High King of Ireland with his brother or half-brother Conaing Bececlach. They took power after killing the previous High King, Eochu Uairches. Eochu ruled the southern half of Ireland, Conaing the north.

Their parentage is unclear. The Lebor Gabála Érenn reports two possibilities: that he and Conaing were the sons of Congal, son of Lugaid Cal of the Corcu Laigde of County Cork; or that Eochu was the son of Congal, and Conaing was the son of Dui Temrach, son of Muiredach Bolgrach, but both had the same mother, who was also the mother of Eochu Uairches. Geoffrey Keating makes them both sons of Dui Temrach, and the Four Masters make them the sons of Dui's son Congal Coscarach. After five years of joint rule, Eochu was killed by Eochu Uairches' son Lugaid Lámderg. According to the Lebor Gabála, Conaing remained in power in the north, while Lugaid took the south. The Annals of the Four Masters say Lugaid ousted Conaing and took complete control of Ireland.

The Lebor Gabála synchronises the reign of Eochu and Conaing with that of Artaxerxes I of Persia (465–424 BC).

Editorial summary

“Eochu Fíadmuine” enters the record as irish king. Crown Archives preserves that source wording while asking what Eochu, Fíadmuine and Irish can confirm, complicate or overturn.

Editorial reviewA productive starting point for separating a subject’s documented career from later reputation and commemoration. The current 198-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Eochu, Fíadmuine and Irish.
Editorial analysis

Why this record matters

“Eochu Fíadmuine” is worth following because a concise public description often conceals a longer documentary argument. Here, Eochu, Fíadmuine and Irish provides the most credible route into that argument.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Apr 12, 2022. The linked authority identifier is Q1271481. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. 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.
