Guaire Aidne mac Colmáin
Irish king
Guaire Aidne mac Colmáin (died 663) was a king of Connacht. A member of the Ui Fiachrach Aidhne and son of king Colmán mac Cobthaig (died 622). Guaire ruled at the height of Ui Fiachrach Aidne power in south Connacht.
Early reign
Guaire appears to have succeeded his father as king of the Ui Fiachrach Aidhne in 622. In 629 was fought the Battle of Carn Feradaig (Carhernarry, County Limerick), where he suffered a defeat at the hands of the Munster king Faílbe Flann mac Áedo Duib (died 639). His ally Conall mac Máele Dúib of the Ui Maine was slain. According to Keating, Guaire's reason for this campaign was to recover the Thomond region from Munster. Prof. Byrne believes that this defeat marked the true expansion of the Déisi Tuisceart into Thomond. He also states that this defeat may have paved the way for Rogallach mac Uatach (died 649) in acquiring the overlordship of Connacht.
