Ruaidrí na Saide Buide Ua Conchobair

The kings of Connacht had, for several hundred years, belong to the Uí Briúin kindred, who traced their descent from a half-brother, Brion, of Niall of the Nine Hostages.

In the 1070s, Brian Bóruma's grandson Toirdelbach Ua Briain was the leading king in Ireland, and if he was less powerful than his propagandists then and later would claim, he exercised a significant influence over Connacht.

First, the Uí Briúin Aí, led by the descendants of Conchobar mac Taidg Mór, the family of Ua Conchobair (modern O'Connor), whose power-base lay in central Connacht, originally centred on the important royal site of Cruachan.

The third group were the Uí Briúin Seóla, whose leading family was the Ua Flaithbertaig (modern O'Flaherty), who dominated Iarchonnacht.

The Annals of Ulster call him "overlord of the province of Connacht, valiant steersman of Leth Cuinn" in the report of his death.

The Annals of Innisfallen record that he was captured by Toirdelbach Ua Briain, King of Munster, and released for tribute.

Dubhchobhlaigh, daughter of Ruaidhri na Soighe Buidhe Ua Conchobhair, lady of Luighne, died.
