Uí Díarmata was a local kingdom located in what is now north County Galway.

County Galway County in the Republic of Ireland

County Galway is a county in Ireland. It is located in the West of Ireland, part of the province of Connacht.



The ruling dynasty took its name from King Diarmait Finn of Connacht (died 833), and the territory in turn was named after them. It seems to have been created by the Uí Briúin in the ninth century during a wave of expansion under his grandson, Uatu ua Diarmada. Its kings appeared regularly in the annals from 971 onwards

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.


By the 11th century its kings had taken the surname Ó Con Cheanain (Concannon). The Annals of Connacht state that "Domnall son of Aed O Con Chenainn, king of the Uí Diarmata, and Muirchertach his brother" were killed at the Second Battle of Athenry in 1316. By this stage it had become incorporated into the territory of Clantaie O Dermod (Clann Taidg and Uí Díarmata) ruled by the de Berminghams, Baron Athenry.

The Annals of Connacht, covering the years 1224 to 1544, are drawn from a manuscript compiled in the 15th and 16th centuries by at least three scribes, all believed to be members of the Clan Ó Duibhgeannáin.

The Second Battle of Athenry took place at Athenry in Ireland on 10 August 1316 during the Bruce campaign in Ireland.

Clann Taidg

Clann Taidg was the name of a medieval cantred located in what is now County Galway, Ireland.

Writing at Tuam on 13 September 1838, John O'Donovan wrote "Henry O'Concanon Esq. of Waterloo near Glentaun in the parish of Killascobe in the Barony of Tiaquin enjoys hereditary property, and is the reputed head of this once respectable family." (2009, p. 35)

Tuam Town in Connacht, Ireland

Tuam ; Irish: Tuaim[t̪ˠuəmʲ]) is a town in Ireland and the second-largest settlement in County Galway. It is situated west of the midlands of Ireland, approximately 35 km (22 mi) north of Galway city. Human existence in the area dates to the Bronze Age while the historic period dates from the 6th century. The town became increasingly important in the 11th and 12th centuries in political and religious aspects of Ireland. The market-based layout of the town and square indicates the importance of commerce.

John O'Donovan, from Atateemore, in the parish of Kilcolumb, County Kilkenny, and educated at Hunt's Academy, Waterford, was an Irish language scholar from Ireland.

Iar Connacht

West Connacht was a kingdom of Gaelic Ireland, associated geographically with present-day County Galway, particularly the area known more commonly today as Connemara. The kingdom represented the core homeland of the Connachta's Uí Briúin Seóla kindred and although they ruled, there were smaller groups of other Gaels in the area, such as the Delbhna Tir Dha Locha and the Conmhaícne Mara. It existed from 1051 onwards, after the Ó Conchobhair, Kings of Connacht, pushed the Ó Flaithbheartaigh to the West of Lough Corrib, from their original territory of Maigh Seóla. Iar Connacht remained a subordinate túath of Connacht, until the 13th century, after which it was more independent.

Maigh Seóla

Maigh Seóla, also known as Hy Briuin Seola, was the territory that included land along the east shore of Lough Corrib in County Galway, Ireland. It was bounded to the east by the Uí Maine vassal kingdom of Soghain and extended roughly from what is now Clarinbridge in the south to Knockmaa Hill in the north. Its rulers belonged to the Uí Briúin Seóla and are sometimes found in the annals under the title "King of Uí Briúin" and "King of South Connacht". The earliest identifiable kings belonged to the line that became the Clann Cosgraigh. However in later times the line which would become the Muintir Murchada, under the O'Flaherty chiefs, monopolized the kingship.

They were originally kings of Maigh Seóla and Muintir Murchada and as members of the Uí Briúin were kinsmen of the Ó Conchubhair and Mac Diarmada amongst others. After their king Cathal mac Tigernán lost out to Áed in Gai Bernaig in the 11th century, the family were pushed further west to Iar Connacht, a territory associated with Connemara today.
