Overview
The Corcu Loígde were the rulers of Munster, and likely of territories beyond the province, until the early 7th century AD, when their ancient alliance with the
Kingdom of Osraige fell apart as the
Eóganachta
The Eóganachta (Modern , ) were an Irish dynasty centred on Rock of Cashel, Cashel which dominated southern Ireland (namely the Kingdom of Munster) from the 6/7th to the 10th centuries, and following that, in a restricted form, the Kingdom of De ...
rose to power. Many peoples formerly subject to the Corcu Loígde then transferred their allegiance to the Eóganachta, most notably the influential
Múscraige, an

people related only very distantly to the Corcu Loígde. The Múscraige became the chief facilitators for the Eóganachta in their rise to power.
Uí Néill interference has also been suggested as a major factor, motivated by a desire to see no more Kings of Tara from the Corcu Loígde.
However, from
Aimend, daughter of
Óengus Bolg, the Corcu Loígde are related to the inner circle of the Eóganachta through a legendary marriage, as she became the wife of
Conall Corc. They enjoyed a privileged status in the history of the new dynasty. As former rulers of the province the Corcu Loígde were not a tributary kingdom, a status also enjoyed by the Osraige.
In the 12th century, they had their kingdom erected into the
Diocese of Ross, and their O'Driscoll lords played a significant maritime role in the region.
Coffey,
O'Leary,
Hennessy, and
Flynn (O'Flynn Arda) were other families of importance, as well as the literary family of
Dinneen.
O'Hea,
Cronin,
Dunlea, and other families also may belong to the Corcu Loígde.
A substantial part of the profitable maritime lands once dominated solely by the Corcu Loídge were incorporated into the medieval
Barony of Carbery, in which the O'Driscolls would retain some status as one of the three princely families underneath the
MacCarthy Reaghs. Some of the western portion of their territory became the
Barony of Bantry.

Eochaid Étgudach
Another Irish monarch belonging to the Corcu Loígde was
Eochaid Apthach, but if in any way historical he has not only been misplaced chronologically but cannot be even placed in the above pedigree due to the extensive corruption of the supposed generations preceding "Bolg" (Sithbolg). It was early noted by
John O'Donovan and has been noted repeatedly by all his successors that the Corcu Loígde genealogies are among the most confused in the entire Irish corpus, so the above scheme should be understood with that in mind.
One important generation not reproduced here is that of
Deda (a quo Clanna Dedad), the most recent common ancestor of the
Dál Fiatach and
Dál Riata of Ulster and Scotland in several official pedigrees. However, variants of his name can be found in the early generations of several Corcu Loígde pedigrees: ''Deaghmanrach'', ''Deadhmannra'' and ''Deagha Dearg''.
Legend and history
A peculiar fact about the Corcu Loígde is their almost total lack of political activity following the mid
Early Middle Ages
The Early Middle Ages (or early medieval period), sometimes controversially referred to as the Dark Ages (historiography), Dark Ages, is typically regarded by historians as lasting from the late 5th to the 10th century. They marked the start o ...
. Having formerly held sway over a vast territory, they appear to have almost completely disintegrated over the course of the 7th century, never making any serious attempts to recover what was at that time the largest kingdom in Ireland. Thus over the next centuries their former grandeur became more and more the stuff of legend, around which the younger kingdoms built their own origin legends. The most well known tale in this cycle is the ''
Cath Maige Mucrama''.
Satellite kingdoms
Former satellite kingdoms of the Corcu Loígde, and who may once have been closely related to them, were probably the early medieval sister kingdoms of
Uí Fidgenti and
Uí Liatháin. Evidence for this is that not only do they appear to have been artificially attached to the stem of the Eóganachta, whose own pedigree is very unreliable before Conall Corc, but that important early septs like the
Uí Duach Argetrois of Osraige cannot be definitively attached to the lines of either the Uí Liatháin-Fidgenti or the Corcu Loígde. In addition there were an early line of O'Learys attached to the Uí Fidgenti.
Later centuries

By the late 16th century, the two most prosperous families remaining were the
Ó hEidirsceoil princes, with several castles in and around

, including
Dunasead Castle, and the O'Learys, who had built several castles south of
Macroom.
The Ó hEidirsceoil's and Baltimore
The history of the
Ó hEidirsceoil clan and the seaside village of Baltimore are inextricably linked. The first historical mention of the Ó hEidirsceoil (anglicised O'Driscoll) clan occurs in the Annals of Inisfallen where the death in 1103 of Conchobar Ua hEtersceóil king of Corcu Loígde was recorded. The surname O'Driscoll is an anglicised form of the Gaelic Ó hEidirsceóil which has the meaning of "diplomat" or "interpreter." ( 'between' + 'story', 'news').
The originator of the name is thought to have lived in the 9th century. Prominent in the village today is the restored castle of Dunasead (castle of jewels) which was an Ó hEidirsceoil stronghold built around 1600 as a fortified house probably by Sir Fineen Ó hEidirsceoil, who was a knight of Queen Elizabeth I. As the power of the Corcu Loígde alias Dáirine as Kings of Munster, Tara, and a large part of Ireland faded in the Dark Ages, their empire broken up, their center of political power shifted south into the wild country of West Cork, or Ross Carbery as it is known in local history, and this is where the O'Driscoll clan has been prominent throughout history.
Baltimore is a strategic harbour town on
Roaringwater Bay located west of
Kinsale and east of
Mizen Head. The west side of Baltimore harbour is bounded by
Sherkin Island which protects it from the prevailing westerly winds and seas. The north side is bounded by Ringarogy island and Spanish Island (also known as Green's Island), which lie in the mouth of the Ilen river. The harbour has two main entrances. The entrance on the south side, called the Harboursmouth, gives direct access to the sea, and is marked by a stone pillar painted white (known locally as "The beacon") on the mainland side, and by a lighthouse at Barracks point on Sherkin Island. On the north side, there is a channel between Sherkin Island and Spanish Island. During the medieval period which was the height of the Ó hEidirsceoil's influence, they controlled the fortresses of Dún na Long (The fort of ships) on Sherkin Island, Dún na Séad (The fort of jewels) at Baltimore, and Dún an Óir (The fort of gold) on Cape Clear, as well as another near
Lough Ine, which is a salt water lake on the nearby coast to the east of Baltimore. The Ó hEidirsceoil heritage is territorially associated with these lands around Baltimore, and an oral legend has it that if any seafarer were to land on the Islands of Sherkin or Clear or the mainland of West Carbery, that an Ó hEidirsceoil would require payment of a dockage fee. The Ó hEidirsceoil's were historically a seafaring clan who had up to 100 sailing vessels in their fleet which were used in both fishing and policing the local waters. The Ó hEidirsceoil's in this era were known to trade extensively with

Sir Fineen is remembered locally as somewhat of a rogue since as a political expedience he opened the local lands to English "planters" and in doing so saved his homelands from falling to local invasion by the local O'Mahony, O'Leary and MacCarthy clans, with the help of the English whose fleet he harboured. Sir Fineen himself was driven in his dotage to live on a small island in Lough Ine as a recluse and oral history claims that he grew rabbit's floppy ears.

whose death preceded his own. His heirs may have survived in Baltimore and abroad but were never again political chiefs in the historical era.
Several years after Sir Fineen's demise, the village of Baltimore suffered a catastrophic defeat as recorded in the Annals of Kinsale, when it was sacked in 1631 by Algerian mercenaries led by a Dungarvan man John Hackett who was later hanged for this crime of revenge. Legend has it that Hackett's boat was seized by the Algerians and that he refused to guide them into Kinsale but instead led the Barbary coast pirates to Baltimore claiming its riches possibly because of the historical dispute between Waterford and the Ó hEidirsceoils. Ironically, nearly all of the 107 captives that were taken from Baltimore by the Turks were for the most part the English "planters," who were made into galley slaves or harem girls and only two of whom were ever returned to Ireland.
The Ó hEidirsceoil's appear to have survived the Sack of Baltimore quite well either in the offshore islands or by clinging to the highlands of "The Hill" overlooking Baltimore's cove where the pirates landed, or retreating to the surrounding hollows or to the upstream town of Skibbereen. To the current time, the Ó hEidirsceoil's claim ownership of "The Hill" in Baltimore as well as many lots and farms in the Islands as well as on the nearby River Ilen and to many other properties in West Cork.

French wine
Corcu Loígde trade with France dates from the Middle Ages. The Ó hEidirsceoils are known from an early time to have had a trading fleet active along the French Atlantic Coast in the
Bay of Biscay, as far south as
Gascony, importing wine back to their region and into Munster.
Hennessy Cognac
After serving as a mercenary for
Louis XV of France, the Corcu Loígde nobleman Richard Hennessy would establish his famous
Hennessy Cognac on land given to him by the king in compensation. Several of his descendants have gone on to distinguish themselves in French politics, notably
Jean Hennessy.
