Thomond before the Norman invasion of Ireland
Thomond (Irish: Tuadhmhumhain, meaning North Munster, now spelled Tuamhain) is a region of Ireland associated with County Clare, County Limerick, north County Kerry and north County Tipperary; effectively most of north Munster. The name is used by a variety of establishments and organisations located in, or associated with the region. Thomond College of Education, Limerick was a teacher training college in Limerick City, until it was amalgamated with the University of Limerick. Thomond Park in Limerick is the rugby stadium used by the Munster Rugby team. Thomond Villas is the name given to the old army barracks at Clarecastle. The Thomond Bridge was for centuries the only bridge crossing the River Shannon in the ancient walled city of Limerick and still carries the road from the city of Limerick through a district known as Thomondgate.
The entire Province of Munster was under the control of the O'Brien (Ua Briain) clan under the leadership of Toirrdelbach Ua Briain and his son Muirchertach from 1072-1114. Their capital was located in Limerick. In a bid to secure the High Kingship of Ireland for the clan, Muirchertach encouraged ecclesiastical reform in 1111 with the creation of territorial dioceses over the entire island. They had support for their bid from several foreign connections including Magnus Bareleg, the king of Norway and the Norman baron Arnulf of Montgomery in Wales who were both united to the clan through marriage in 1102. Their claim to the High Kingship was countered by the O'Neill (Uí Néill) clan in Ulster under the leadership of Domnall MacLochlainn of Ailech. Though Muirchertach campaign hard in the north he was unable to obtain submission. When he fell ill in 1114 he was deposed by his brother Diarmait. Muirchertach did briefly regain power of the clan but after his death in 1119 his brother's sons took control of the clan.
MacLochlainn's plans to restore the High Kingship to the north was thwarted by his ally Tairrdelbach Ua Conchobair of Connaght who formed an alliance with the O'Brien's. In 1118 Conchobair partitioned Munster between the sons of Diarmait and Tagh Mac Carthaig. The northern section of the province became the O'Brien Kingdom of Thomond and the southern became the Mac Cathaig Kingdom of Desmond.
In 1841, an estimation of the extent of the kingdom was undertaken by John O'Donovan and Eugene Curry
"The principality of Thomond, generally called the Country of the Dal-Cais, comprised the entire of the present Co. of Clare, the Parishes of Iniscaltra and Clonrush in the County of Galway, the entire of Ely O'Carroll, the Baronies of Ikerrin, Upper and Lower Ormond, Owney and Arra, and somewhat more than the western half of the Barony of Clanwilliam in the County of Tipperary; the Baronies of Owenybeg, Coonagh and Clanwilliam, and the eastern halves of the Baronies of Small County and Coshlea in the County of Limerick."
