Áed mac Ainmuirech

Who was Áed mac Ainmuirech?

Áed mac Ainmuirech was high-king of the Northern Uí Néill. He belonged to the Cenél Conaill and was a distant cousin of Columba of Iona. He was the son of Ainmuire mac Sétnai, a previous possible high king.

He came to power some decades after the death of the last old, pagan style high-king of Tara, Diarmait mac Cerbaill, after a period in which it is not clear that the Uí Néill had a high-king, nor is it certain that his contemporaries would have acknowledged Áed as such. The high kingship of Ireland rotated between the Cenél nEógain and Cenél Conaill branches in the late 6th century. It is difficult to disentangle the reign of Áed from that of his older second cousin Báetán mac Ninneda. Various lengths are given to the reign of Áed in the kinglists all of which would put the start of his reign before the death of Báetán. Both kings are omitted fron the Baile Chuinn, the earliest Irish king list of the late 7th century, but this was probably a partisan document. It is possible that Báetán was not actually high king but was given this position by the synthetic historians to explain away the rule of Báetán mac Cairill of the Dal Fiatach of Ulster as high king. The kinglists only assign him a reign of one year. Whether Báetán was king of Tara or not, the real effective power among the northern Ui Neill was Áed mac Ainmuirech.
