Events from the 10th century in Ireland.

Uí Briúin

The Uí Briúin were a royal dynasty of Connacht. Their eponymous apical ancestor was Brión, son of Eochaid Mugmedon and Mongfind, and an elder half brother of Niall of the Nine Hostages. They formed part of the Connachta, along with the Uí Fiachrach and Uí Ailello, putative descendants of Eochaid Mugmedon's sons Fiachra and Ailill. The Uí Ailello were later replaced as the third of the Three Connachta, by genealogical sleight of hand, by the Uí Maine.

Connachta

The Connachta are a group of medieval Irish dynasties who claimed descent from the legendary High King Conn Cétchathach. The modern western province of Connacht takes its name from them, although the territories of the Connachta also included at various times parts of southern and western Ulster and northern Leinster. Their traditional capital was Cruachan.

The Uí Fiachrach were a dynasty who originated in, and whose descendants later ruled, the coicead or fifth of Connacht at different times from the mid-first millennium onwards. They claimed descent from Fiachrae, an older half-brother of Niall Noigiallach or Niall of the Nine Hostages. Fiachrae and his two full brothers, Brion and Ailill, were the collective ancestors of the Connachta dynasty that eventually became the new name of the province. Their mother was Mongfind.

Connacht was generally subjected to the Ui Neill high kings at this time and in 897, the high king Flann Sinna (died 916) attacked Connacht and secured its pledges. [3] In 899 though, the Connachta made a raid into Westmeath but were defeated at Áth Luain. [4] The Annals of the Four Masters associate this raid with the renewal of the fair of Connacht by Tadg. [5] The annals record Tadg's death the next year "after prolonged suffering" [6]
