Conn of the Hundred Battles was a legendary High King of Ireland who is claimed to be the ancestor of the Connachta, and through his descendant Niall Noígiallach, the Uí Néill dynasties, which dominated Ireland in the early Middle Ages.
Although some historians regard him as a purely mythical figure, the Irish Annals suggest that his rule over the northern half of Ireland was real, and that his epithet was used to extalt his image as an invincible warrior. Modern linguists suggest that the Gaelic term cét- sometimes meant ‘first’ or ‘primal’, and cathach translates as ‘warrior’. Thus, the name originally meant ‘the first great warrior’, a term which over time came to be popularly interpreted as ‘a hundred battles’. He is such a central figure in Irish mythology that the province of Connacht takes its name from him
The Lebor Gabála synchronises Conn's reign with that of the Roman emperor Marcus Aurelius (161–180). The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to 116–136, that of the Annals of the Four Masters to 122–157.
