Muirchertach mac Muiredaig (died c. 534), called Mac Ercae, Muirchertach Macc Ercae and Muirchertach mac Ercae, was said to be High King of Ireland in the 6th century. The Irish annals contain little reliable information on his life, and the surviving record shows signs of retrospective modification. The Aided Muirchertaig Meic Erca takes as its theme Muirchertach's supernatural death.
According to the genealogies, Muirchertach belonged to the Uí Néill and was the son of Muiredach, son of Eógan, son of Niall of the Nine Hostages; hence Muirchertach mac Muiredaig. His mother, "obviously legendary" according to Thomas Charles-Edwards, was said to be Erca, daughter of "Lodarn, king of Alba". From the matronym comes his alternative name, Muirechertach Macc Ercae. However, Mac Ercae was a common enough male first name. [1] The annalistic entries for Muirchertach span 50 years, from 482 to his death in 534, using various names, including Mac Ercae, so that it is more than likely that two or more people have been confused in the annals.
The first mentions of Muirchertach in the Annals of Ulster , in 482 and 483, associate him, under the name Muirchertach Macc Ercae, with the defeat and killing of Ailill Molt at the battle of Ochae, somewhere in the Irish midlands. [2] One entry names Lugaid mac Lóegairi as his ally there, the other names Fergus Crook-mouth, father of Diarmait mac Cerbaill. [3] In 485, the annals mention the battle of Grainert, perhaps near Castledermot, [2] where Coirpre mac Néill, "or Mac Ercae… as other state", defeated the Leinster king Finnchad mac Garrchon. [4] In 490 or 491, Óengus mac Nad Froích is said to have been killed at the battle of Cell Losnaid, and the second entry reports that "Mac Ercae was the victor". [5] Muirchertach Mac Ercae is said to have won the battle of Inne Mór against the Leinstermen in 498. [6] Many of the entries from the 480s and 490s appear to have been modified, to give Muirchertach the credit for victories won by Coirpre mac Néill and perhaps by Coirpre's son Eochu. [7]
The obituary of Lugaid mac Lóegairi appears in 512, and in the following year the annalist reports the beginning of the reign of Muirchertach Mac Ercae. The next report is in 520, duplicated in 523, stating that Muirchertach was among the victors at the battle of Dethna. Another battle follow in 528, again repeated some years later, in 533, with more detail. [8] Muirchertach's death is reported in 534, with obvious supernatural overtones: "The drowning of Muirchertach Mac Erca i.e. Muirchertach son of Muiredach son of Eógan son of Niall Naígiallach in a vat full of wine on the hilltop of Cleitech above Bóinn." [9] Muirchertach was said to be followed as High King by Túathal Máelgarb.
Báetán mac Muirchertaig (died 572),[1] called also Baetán Bríge, was a son of Muirchertach mac Muiredaig, ruled in Ailech from 566 to 572 and was included in some lists as a High King of Ireland. Domnall Ilchelgach (Domnall of the Many Deceits) (died c. 566), called Domnall mac Muirchertaig, and Domnall mac Mac Maic Ercae, said to be a High King of Ireland, was probably also a son of Muirchertach mac Muiredaig. Muirchertach's descendants in time took the name Cenél maic Ercae and were the dominant branch of the Cenél nEógan by the middle of the 8th century.
The 12th-century Middle Irish tale Aided Muirchertaig Meic Erca is an account of Muirchertach's supernatural death. Here Muirchertach dies in the House of Clettach, drowned in a vat of wine, burned by fire, and crushed by a falling roof beam, near Brú na Bóinne, beguiled by the illusions of the otherworldly maiden Sín into believing that he is being attacked by Túathal Máelgarb. [10] The manner of his demise is an example of the "Threefold death," a feature of Indo-European mythology and Celtic literature.
Lugaid mac Lóegairi was a High King of Ireland. He was a grandson of Niall of the Nine Hostages.
Diarmait mac Cerbaill was King of Tara or High King of Ireland. According to traditions, he was the last High King to follow the pagan rituals of inauguration, the ban-feis or marriage to goddess of the land. The last High King to observe the ancient pagan Feis Temrach or Assembly of Tara which took place on Samhain every three years to pass or renew laws, approve annals and records.
The Kings of Ailech were the over-kings of the medieval Irish province of Ailech in north-western Ireland. It encompassed the territories of the Cenél nEógain and Cenél Conaill. After the battle of Cloítech in 789 its kings were exclusively from the Cenél nEógain. The royal fort for Ailech was the Grianan of Aileach, a hillfort on top of Greenan Mountain in modern-day County Donegal, Republic of Ireland.
Domhnall Ua Lochlainn, also known as Domhnall Mac Lochlainn, was king of the Cenél Eogain, over-king of Ailech, and alleged High King of Ireland.
Túathal mac Cormaic, called Túathal Máelgarb, was said to be a grandson of Coirpre mac Néill. He was High King of Ireland. In the earliest accounts he appears to have been regarded as the man who completed the conquest of what would later be Brega for the descendants of Niall of the Nine Hostages.
Áed mac Ainmuirech was High King of the Northern Uí Néill. He belonged to the Cenél Conaill and was a distant cousin of Columba of Iona. He was the son of Ainmuire mac Sétnai, a previous possible high king. His mother was Bríg, daughter of Chobtaig, son of Ailill, son of Nath Í, son of Crimthann mac Énnai son of Énnae Cennsalach of the Uí Ceinnselaig dynasty from Leinster. He was born in 530 according to the Annals of Tigernach (596.2).
Coirpre mac Néill, also Cairbre or Cairpre, was said to be a son of Niall of the Nine Hostages. Coirpre was perhaps the leader of the conquests that established the southern Uí Néill in the midlands of Ireland. The record of the Irish annals suggests that Coirpre's successes were reattributed to Muirchertach Macc Ercae. Coirpre is portrayed as an enemy of Saint Patrick in Bishop Tirechán's hagiography and his descendants are said to have been cursed by Patrick so that none would be High King of Ireland. Coirpre is excluded from most lists of High Kings, but included in the earliest.
Ainmuire mac Sétnai or Ainmire or Ainmere was a High King of Ireland from the Cenél Conaill branch of the Uí Néill. He was the great-grandson of Conall Gulban, founder of this branch. He ruled from 566 to 569. He was the first high king from the Cenél Conaill.
Áed Uaridnach was an Irish king who was High King of Ireland. He is sometimes also known as Áed Allán, a name most commonly used for the 8th-century king of the same name, this Áed's great-great-grandson.
Eógan Bél mac Cellaig was a king of Connacht from the Uí Fiachrach branch of the Connachta. He was the grandson of the high king Ailill Molt. His reign began sometime after 500. His byname bél means "mouth" or "lip," supposedly because he received praise from all who encountered him as a child. Other sources claim he had a cleft lip.
Ailill Inbanda mac Eógain was a king of Connacht from the Ui Fiachrach branch of the Connachta. He was the son and successor of Eógan Bél, who was slain by the northern Ui Neill in 542. His nickname Inbanda means "womanish" or effeminate or it could mean "the vigorous" which is more likely.
Forggus mac Muirchertaig, also called Forrgus mac Maic Ercae, is included in most lists of High Kings of Ireland.
