 were sometimes called high-kings but were not recognized as kings of all Ireland in the historical period. However, this is to put the supposed office "High King of Ireland" on a platform that it probably never enjoyed. The social structure of Gaelic Ireland was extremely complex, heirarchically oriented and aristocratic in concept. At the summit of society stood the king of a province, variously styled in the law texts as "King of great kings" , "Chief of kings" and "The ultimate king of every individual" . From his justice there was no appeal, nor did the Brehon Law acknowledge the existence of the high-kingship of Ireland. The ri ruirech had no legal superior. In Munster this legal theory was explicitly adhered to by the annalists who styled the provincial kings as "High-king" thereby stressing his absolute sovereignty. As the concept of the high-kingship of Ireland was developed from the ninth century onwards by the Uí Néill clan, the kings of Munster counterbalanced this unhistorical doctrine by stressing their alternate right to that office or, in lieu, the enjoyment of full sovereignty in Leth Mogha, that part of Ireland lying south of an imaginary line drawn from Dublin to Galway.

The Eóganacht king Fíngen mac Áedo Duib or Fingin son of Hugh Dubh ruled as King of Munster (died 618 CE) and is the direct male line ancestor of the O'Sullivans. His son Seachnasagh was too young to assume the throne and was therefore followed by Eóganacht king of Munster Faílbe Flann mac Áedo Duib
Faílbe Flann mac Áedo Duib
Faílbe Flann mac Áedo Duib was a King of Munster from the Eóganacht Chaisil branch of the Eoganachta. He succeeded Cathal mac Áedo Flaind Chathrach of the Glendamnach branch in 628. He was the younger brother of a previous king Fíngen mac Áedo Duib...

, direct male line ancestor of the later MacCarthy kings. In the Roll of "The Kings of Munster", under the heading "Provincial Kings," we find that Fingin, son of Hugh Dubh, is No.14 on that Roll, while his brother Failbhe is No.16 thereon. The MacCarthy's owed their prominent position they held in Desmond at that period of the English invasion of Ireland, not to primogeniture, but to the disturbed state and choas of Munster during the Danish wars, in which their immediate ancestors took a prominent and praiseworthy part.

Gentle rulers

The rule of the Eóganachta in Munster is widely regarded as gentle and more sophisticated in comparison with the other provincial dynasties of Ireland. Not only was Munster the wealthiest of the provinces, but the Eóganachta were willing to concede other previously powerful kingdoms whom they had politically marginalized, such as the Corcu Loígde
Corcu Loígde

The Eóganachta achieved their status primarily through political and economic sophistication and not military conquest. Ireland was dominated by several hostile powers whom they were never in any position to challenge militarily on their own, in the initial centuries, but there also existed a number of subject tribes whom the Deirgtine successfully convinced to adopt them as their overlords. The effect was to separate the Dáirine, by now mainly the Corcu Loígde, from their cousin kingdoms and prominent subjects. The Eóganachta progressively surrounded themselves with favoured vassals such as the Múscraige

The princely houses of the Eóganachta may usefully be divided into the inner circle, the outer circle and extinct septs.

Princely houses: inner circle

  • Eóganacht Chaisil
  • Eóganacht Áine
  • Eóganacht Glendamnach


These three princely houses produced nearly all Kings of Cashel from the 5th to the 10th centuries. Some were strong, others were renowned bishops and scholars, and others were weak. The importance of the Cashel kingship was primarily ceremonial, and rulers were with the occasionl exception not militarily aggressive... although they continually strove for political dominance as far as they could with the province's wealth. Strong petty kingdoms regarded as subject would receive large payments called rath in return for their acknowledgment of the political supremacy of Cashel, and they would sometimes give hostages as well. The most powerful petty kingdoms exchanged hostages with the King of Cashel, and though subject in some sense (by agreement), they were legally free and capable of terminating the contract.

The Eóganacht Chaisil under the MacCarthys would later form the much more militarily capable but unfortunately undermanned Kingdom of Desmond. The O'Sullivans the eldest of the Eóganacht Chaisil were the most powerful lords under them. The O'Keeffes of Eóganacht Glendamnach would later produce many great soldiers for Irish and Continental armies. The O'Callaghans were a smaller sept who have since distinguished themselves in recent times, while the MacAuliffes and MacGillycuddys are as stated simply septs of the MacCarthys and O'Sullivans.

Princely houses: outer circle

  • Eóganacht Locha Léin
  • Eóganacht Raithlind


The two "outer" princely houses of the dynasty dwelt to the west and south of the central dynasties. Though descended from Conall Corc and thus theoretically entitled to hold the kingship, in effect these dynasties were excluded from Cashel politics, a situation which may or may not have been based on geographical realities. Powerful kings could become de facto Kings of Munster, but in general the central dynasties refused to recognize them as such, and this resulted in particular antagonism between Cashel and Eóganacht Locha Léin, the power of which was eventually broken. Eóganacht Raithlind was not as aggressive and so survived under O'Mahony rule well into the 2nd millennium. The O'Donoghues, originally from Eóganacht Raithlind, would move in to become the new princes of Eóganacht Locha Léin, and are still represented among the Irish nobles today by the Lord of Glenflesk (see below).

Oddly enough, the Eóganacht Raithlind, the Eóganacht Locha Léin, and the Uí Fidgenti-Liatháin (below), are all together referred to as the Three Eóganachta of Munster in early medieval story known as The Expulsion of the Déisi
The Expulsion of the Déisi
The Expulsion of the Déisi is a medieval Irish narrative of the Cycles of the Kings. It dates approximately to the 8th century, but survives only in manuscripts of a much later date. It describes the fictional history of the Déisi, a group that had gained political power in parts of Ireland during...

The term is Old Irish, and derives from the word déis, meaning "vassal" or "subject"; in its original sense, it designated groups who were vassals or rent-payers to a landowner. Later, it became a proper name for certain septs and...

Out of the approximately 150 surviving Irish surnames of princely or comital origins, the Eóganachta and their allies account for approximately 30, or about one fifth.

They paid no obvious tribute but were little involved in the political scene after a period, the terms of the alliance being only that they were expected to support the Eóganachta militarily on "honour related" expeditions outside Munster or in the defence of it. The Uí Fidgenti did exchange hostages with the King of Cashel, just like the Eóganacht Raithlind and Eóganacht Locha Léin were honoured, and so they appear to have been viewed as kin from an early period, even if they may have been Dáirine to begin with or included very substantial elements.
