Flaithbertach Ua Néill (before 978–1036) was
king of Ailech, a kingdom of north-west Ireland. He abdicated in 1030 and undertook a pilgrimage to Rome, for which reason he was known as Flaithbertach an Trostáin (Flaithbertach of the

[Duffy, ''Atlas of Irish History'', pp. 26–31.]
The Cenél nEógain
kings of Ailech were based originally in Inishowen. By the 9th century, however, Cenél nEógain power had extended eastwards, into lands which had once belonged to the kingdom of Ulster and the Airgíalla, and kings were inaugurated at Tulach Óg (
Tullyhogue Fort,
County Tyrone) and buried at
Armagh. While not directly under the control of the kings of Ailech, Armagh was subject to their influence and it is recorded that the kings kept a house there. Although the

in 1152, its authority over the churches of the north and centre of Ireland in Flaithbertach's time was much greater, as shown by the earlier boundaries between provinces established at the
Synod of Ráith Bressail in 1111, which divided Ireland between Armagh and
Cashel. Armagh was not only
Saint Patrick's city, it was also in some measure the city of Cenél nEógain. Other major churches in the region, those established as sees following the 12th-century reforms, included the
Columban churches of
Derry and
Raphoe, and the Patrician churches of
Louth,
Maghera and
Connor.
Before Clontarf
The date of Flaithbertach's birth is not certainly known, but his father Muirchertach was killed in 977 by
Amlaíb Cuarán. A late addition to the ''
Annals of Ulster'' claims that Flaithbertach was born that same year. His mother was Cres Cumal of the
Uí Maine.
[Duffy, "Flaithbertach".] His grandfather Domnall ua Néill,
High King of Ireland, died in 980, and the kingship of Ailech passed first to Fergal mac Domnaill meic Conaing, who perhaps abdicated in 989 and died in 1001. Fergal was followed, perhaps after an interval of some years, by Flaithbertach's uncle Áed mac Domnaill, who is said to have been but 29 years of age and in the 10th year of his reign at his death in 1004.
The first report of Flaithbertach is in 1005 when he led a raid on
Leth Cathail, part of the kingdom of Ulster, where the king of Leth Cathail, Áed mac Tommaltaig, was killed. Flaithbertach raided Leth Cathail again in 1007, killing Áed's successor Cú Ulad, and undermining the settlement imposed in 1005 when
Brian Bóruma came to Armagh with a great army and received Flaithbertach's submission. Brian returned in 1006 and again in 1007, on which occasion he removed some of the hostages Flaithbertach had obtained from Ulster into his own keeping, by force according to the ''
Annals of Innisfallen''. Perhaps at about this time Flaithbertach married Brian's daughter Bé Binn; their children included Áed and Domnall.
Flaithbertach continued to act aggressively towards his neighbours. He had a king of Cenél Conaill blinded and put to death in 1009, and raided the midlands as far as the lower reaches of the
River Boyne later in the year. These actions brought Brian back north in 1010, again receiving Flaithbertach's submission and taking hostages from Cenél nEógain back home to
Kincora. Cenél Conaill was invaded in 1011, this time Flaithbertach acting as Brian's ally, his army accompanying those of Brian's sons Domnall and Murchad. A second expedition by Brian himself late in the year received the submission of Cenél Conaill. Flaithbertach, however, had returned to his old ways and again attacked Ulster, capturing Dún Echdach (Duneight, south of
Lisburn) and receiving the submission of the Ulster over-king Niall mac Duib Tuinne. He attacked Ulster and Cenél Conaill again in 1012.
In 1013 Flaithbertach raided into the
kingdom of Mide, ruled by former High King
Máel Sechnaill mac Domnaill. The two armies met near
Kells, but Máel Sechnaill withdrew his army without fighting. This seemingly minor event appears to have led Máel Sechnaill's neighbours to believe him weak and vulnerable, and a war with

followed. The war ended at the
battle of Clontarf on 23 April 1014, where Brian Bóruma was killed, although his armies and Máel Sechnaill's defeated the Leinstermen and Dubliners.
After Clontarf
With Brian dead, Máel Sechnaill and Flaithbertach embarked on a series of campaigns which reestablished Máel Sechnaill as High King. According to the ''
Cogadh Gaedhel re Gallaibh'', a work of propaganda composed in the time of Brian's great-grandson
Muirchertach, in 1002, shortly before Brian replaced Máel Sechnaill as High King, Máel Sechnaill had offered to resign the High Kingship in favour of Áed mac Domnaill, Flaithbertach's uncle and predecessor as king of Ailech in return for aid against Brian. The ''Cogadh'' states that Áed refused and that no help came to Máel Sechnaill from Cenél nEógain and the north, only from
Connacht
Connacht or Connaught ( ; or ), is the smallest of the four provinces of Ireland, situated in the west of Ireland. Until the ninth century it consisted of several independent major Gaelic kingdoms (Uí Fiachrach, Uí Briúin, Uí Maine, C ...
. What caused Flaithbertach to support Máel Sechnaill where his uncle had not is unknown.
Máel Sechnaill died in 1022. Flaithbertach campaigned in the midlands in 1025 and received the submission of Dublin, but
Donnchad mac Briain did likewise in 1026, and Flaithbertach also that same year. But Dublin appears to have been easy prey for
Niall mac Eochada, the king of Ulster, also raided Dublin in 1026. That year Ulster was raided, and Cenél Conaill the next.
Flaithbertach was by this time over 50 years old. His son Domnall died in 1027 and in 1030 he went on pilgrimage to Rome, returning home in 1031. From this he obtained his
byname, Flaithbertach an Trostáin, that is Flaithbertach of the Pilgrim's staff. That year Niall mac Eochada raided Telach Óg while Flaithbertach's son Áed undertook a raid in reprisal. Also in 1031 Flaithbertach and Áed raided the south part of Cenél Conaill.
At about this time Flaithbertach abdicated, being succeeded as king of Ailech by Áed, but Áed died on 30 November 1033. Flaithbertach left his retirement and became king again, the ''Annals of Innisfallen'' say: "Flaithbertach Ua Néill took Ailech again, and the north of Ireland submitted to him on account of seniority." However, it may be that it was not the death of Áed which led to Flaithbertach's recall as the southern ''
Annals of Innisfallen'' place this event only after the death of Domnall Ua Maíl Doraid of Cenél Conaill. Flaithbertach's second reign was seemingly uneventful. He died in 1036 as king of Ailech.
Flaithbertach is not included in modern lists of High Kings. Nonetheless, some medieval writers identified him with a king included in the list of High Kings in ''
Baile in Scáil'', and it may be that he is included in the verse history of Irish and Scottish kings in prophetic style called the ''
Prophecy of Berchán''. Both of these sources are problematic and neither is generally relied upon for Irish king lists, unlike the much earlier ''
Baile Chuind'', on which they are modelled. Perhaps most conclusively, the historical poems of Flaithbertach's contemporary
Flann Mainistrech and the compilers of the pro-Uí Néill chronicles at
Armagh do not recognise him as a High King.
Following Flaithbertach's death, his descendants were eclipsed by their Meic Lochlainn cousins. The last of the family was recorded in the annals in the 1080s, after which they disappear. Because of this, several Irish academics such as
Francis John Byrne believe the true O'Neill descendants of Niall Glundubh no longer held any power anywhere in Ireland, and that their alleged 12th-century descendant,
Áed in Macáem Tóinlesc was of unknown ancestry and only adopted the surname. Indeed, Áed was a puppet king installed by
Ruaidrí Ua Conchobair who partitioned Cenél nEógain between the Meic Lochlainn and Áed in 1167.
[Flanagan, "Ua Conchobair, Ruaidrí".] Most current bearers of the surname O'Neill claim Áed as their ancestor such as the Scottish
Clan MacNeill.
