Dynasts of Mumhan

The Éoganacht were a federation of tribes claiming a common lineage and spread throughout Munster. They were noted as kings of Munster from an early period until the rise of the Dal gCais in the 10th century. The main sub-tribes in the region of the barony were:

• Eóghanacht Chaisil (Cashel). Septs included O'Callaghan, MacCarthy, MacGillycuddy, MacAuliffe, O'Sullivan.
• Éoganacht Beag Chaisil (Eoganacht Caille na Manach, in the barony of Kilnamanagh)
• Éoganacht Mhór Muman (about Knockgraffon, in the barony of Middle Third)
• Eóghanacht Airthir Chliach (Tipperary town district)
• Eóghanacht Durluis (in or near Thurles, in the barony of Eliogarty)

Dal gCais dynasty. The High King of Ireland, Brian Boru, fortified Cashel in 990. Murtagh O'Brien, King of Cashel, in presence of the chiefs and clergy, made a grant in 1101 of the "Rock" with the territory around it to O'Dunan, "noble bishop and chief senior of Munster". In 1127 Cormac III of Munster, King of Desmond, erected close to his palace on the "Rock" a church, now known as Cormac's Chapel, which was consecrated in 1134. By the Synod of Kells, 1152, Cashel became an archiepiscopal see. There are frequent references to "Tuadh Mumhan" in the Irish Annals beginning in the latter 11th century, but as a separate entity representing all of northern Munster an entry for the year 1118 seems to mark a milestone event. In that year, a treaty at Gleann Maidhir (Glanmire) divided the Kingdom of Munster into northern (Tuadh Mumhan) and southern (Des Mumhan) halves, a division apparently running near the border of modern counties Limerick and Cork. The entry in the Annals for 1118 reads, " A hosting by Toirdhealbhach Ua Conchobhair, king of Connacht, and by Murchadh O Maelsechlainn, king of Temhair, along with him, and by Aed O'Ruairc, into Mumha, as far as Glenn-Maghair; and he gave Des-Mumha to Mac Carthaigh, and Tuadh-Mumha to the sons of Diarmaid Ua Briain, and carried off the hostages of each."

Lordship of Ireland

With this 12th-century division of Munster into two parts, Thomond included the area about the diocese of Killaloe, and additionally encompassed the traditional territories of Úi Fidgeinti, Uí Chonaill Gabra, Eóghanacht Áine, Éile, Corco Mruadh, the tribes of Uaithne (later held by the Síl Cennétich, and much of Eóghanacht Caisel and Ciarraige Luachra.^[1]

By the early 13th century, through the encroachment of the Anglo-Norman Butler family and others into eastern Thomond (north Tipperary, east Limerick and south Offaly), part of which came to be known as Ormond or East Munster, the kingdom of Thomond was greatly reduced.

Diocesan history

Various members of the Desmond and Ormond families became archbishops in the succeeding years up to the English Reformation. After a vacancy of six years Maurice FitzGibbon (1567–1578) a Cistercian abbot who belonged to the royal Desmond family, was promoted to the archbishopric by pope Pius V, but James MacCaghwell was put forward by Elizabeth I of England. Thus began the Anglican religion at Cashel. When the Penal Laws were sufficiently relaxed, the Roman Catholic archbishops returned openly to the see, but changed their residence and cathedra to Thurles.

Modern times

When County Tipperary was split into North and South Ridings in 1836, Middle Third was allocated to the south riding. However, the neighbouring barony of Kilnamanagh was split into Upper and Lower half-baronies, being allocated to the north and south ridings respectively.^[2]

Civil parishes of the barony

This table^[3] lists an historical geographical sub-division of the barony known as the civil parish (not to be confused with an Ecclesiastical parish).

Note: while the civil parish of Holycross straddles two baronies (Eliogarty and this baraony), the village itself and the abbey are entirely located in Eliogarty.
