Ímar ua Ímair

Ímar ua Ímair
King of Dublin
Died	904 Strathearn
House	Uí Ímair

Ímar ua Ímair (Old Norse: Ívarr, died 904) was a Norse or Norse-Gaelic King of Dublin. He was a grandson of Ímar and a member of the Uí Ímair.

Ímar ua Ímair became King of Dublin sometime prior to 902, but probably not before 896 when his uncle (or father) Sitriuc mac Ímair died. In the decades preceding his reign, Dublin was wracked by internal strife and dynastic feuds, greatly weakening the kingdom. The neighbouring native Irish kings sought to take advantage of this to increase their own influence. An additional motivating factor may have been revenge for Viking raids on Irish religious sites – in 890-91 alone the Norsemen plundered Irish monasteries at Ardbraccan, Clonard, Donaghpatrick, Dulane, Glendalough and Kildare.

In 902 the kingdoms of Brega and Leinster formed an alliance and drove the Vikings from Dublin. The exiled Dubliners, led by Ímar ua Ímair, retreated to territory in Scotland over which they exerted some control. The following year they were engaged in warfare with Constantine, King of the Picts, raiding Dunkeld. A victory was won by Constantine the following year at a place identified by the Chronicle of the Kings of Alba as Strath Erenn. Ímar ua Ímair is mentioned in the Annals of Ulster in the same year for the first and only time. This sole entry details his death at the hands of the Picts of Fortriu – this is identified as the same battle as that mentioned in the Chronicle.
