Brian Boru (c. 941 – 23 April 1014, Old Irish language: Brian Bóruma mac Cennétig; Middle Irish language: Brian Bóruma; modern Irish language: Brian Bóroimhe ) was an Irish king who ended the domination of the High Kingship of Ireland by the Uí Néill. Building on the achievements of his father, Cennétig mac Lorcain, and especially his elder brother, Mathgamain, Brian first made himself King of Munster, then subjugated Leinster, making himself ruler of the south of Ireland. He is the founder of the O'Brien dynasty.

With a population of under 500,000 people, Ireland had over 150 kings, with greater or lesser domains.[1] The Uí Néill king Máel Sechnaill mac Domnaill, abandoned by his northern kinsmen of the Cenél nEógain and Cenél Conaill, acknowledged Brian as High King at Athlone in 1002. In the decade that followed, Brian campaigned against the northern Uí Néill, who refused to accept his claims, against Leinster, where resistance was frequent, and against the Norse Gaelic Kingdom of Dublin. Brian's hard-won authority was seriously challenged in 1013 when his ally Máel Sechnaill was attacked by the Cenél nEógain king Flaithbertach Ua Néill, with the Ulstermen as his allies. This was followed by further attacks on Máel Sechnaill by the Dubliners under their king Sihtric Silkbeard and the Leinstermen led by Máel Mórda mac Murchada. Brian campaigned against these enemies in 1013. In 1014, Brian's armies confronted the armies of Leinster and Dublin at Clontarf near Dublin on Good Friday. The resulting Battle of Clontarf was a bloody affair, with Brian, his son Murchad, and Máel Mórda among those killed. The list of the noble dead in the Annals of Ulster includes Irish kings, Norse Gaels, Scotsmen, and Scandinavians. The immediate beneficiary of the slaughter was Máel Sechnaill who resumed his interrupted reign.

The court of Brian's great-grandson Muirchertach Ua Briain produced the Cogadh Gaedhel re Gallaibh, a work of near-hagiography. The Norse Gaels and Scandinavians too produced works magnifying Brian, among these Njal's Saga, the Orkneyinga Saga, and the now-lost Brian's Saga. Brian's war against Máel Mórda and Sihtric was to be inextricably connected with his complicated marital relations, in particular his marriage to Gormlaith, Máel Mórda's sister and Sihtric's mother, who had been in turn the wife of Amlaíb Cuarán, king of Dublin and York, then of Máel Sechnaill, and finally of Brian.

A succinct summation of Brian is by David B. Beougher, who remarks

"Contrary to the popular perception of Brian as the liberator of Ireland from foreign dominance, he purposely used outsiders to expand his authority. Brian "Boru" combined Irish tradition with innovation to become the most successful Irish king of his time."[2]

Biography[edit | edit source]

Early life and background[edit | edit source]

Many Irish annals state that Brian was in his 88th year when he fell in the Battle of Clontarf in 1014. If true, this would mean that he was born as early as 926 or 927.[3] Other birth dates given in retrospect are 923 or 942.[3]

He was one of the 12 sons of Cennétig mac Lorcáin (d. 951), king of Dál Cais and king of Tuadmumu (Thomond), modern County Clare, then a sub-kingdom in the north of Munster). Cennétig was described as rígdamna Caisil, meaning that he was either heir or candidate ("king material") to the kingship of Cashel or Munster,[4] although this might be a later interpolation. Brian's mother was Bé Binn inion Urchadh, daughter of Urchadh mac Murchadh (d. 945), king of Maigh Seóla in west Connacht.[3][4] That they belonged to the Uí Briúin Seóla may explain why he received the name Brian, which was rare among the Dál Cais.[4]

Brian was born at Kincora, Killaloe, a town in the region of Tuadmumu (Thomond).[4] Brian's posthumous cognomen "Bóruma" (anglicised as Boru) may have referred to "Béal Bóruma", a fort north of Killaloe (Co Clare) in Thomond, where the Dál Cais held sway.[3][4][5] Another explanation, though possibly a late (re-)interpretation, is that the nickname represented Old Irish bóruma "of the cattle tribute", referring to his capacity as a powerful overlord.[3]

When their father died, the kingship of Tuadmumu passed to Brian's older brother, Mathgamain, and, when Mathgamain was killed in 976, Brian replaced him. Subsequently he became the King of the entire kingdom of Munster.[6]

Situation of his tribe, the Dál gCais[edit | edit source]

Brian belonged to the Dál gCais (or Dalcassians), a newly styled kin group of ultimately Déisi origin who occupied a territory north of the Shannon Estuary, which today would incorporate a substantial part of County Clare and then formed the core of the new kingdom of Thomond. In earlier times their ancestors had controlled some lands in today's County Limerick as well, but these had been overrun by the Uí Fidgenti from the 9th century and the invading Norse in the 10th.

The River Shannon served as an easy route by which raids could be made against the provinces of Connacht and Meath. Both Brian's father, Cennétig mac Lorcáin and his older brother Mathgamain conducted river-borne raids, in which the young Brian would undoubtedly have participated. This was probably the root of his appreciation for naval forces in his later career. Thus an important influence upon the Dalcassians was the presence of the Hiberno-Norse city of Limerick on an isthmus around which the Shannon River winds (known today as King's Island or the Island Field). The Norse had made many a raid themselves from the Shannon, and the Dalcassians likely benefited from some interaction with them, from which they would have been exposed to innovations such as superior weapons and ship design, all factors that may have contributed to their growing power.

Reign of his brother, Mathgamain[edit | edit source]

In 964, Brian's older brother, Mathgamain, claimed control over the entire province of Munster by capturing the Rock of Cashel, capital of the ancient Eóganachta, the hereditary overlords or High Kings of Munster, but who in dynastic strife and with multiple assassinations had weakened themselves to the point they were now impotent. Earlier attacks from both the Uí Néill and Vikings were factors. This situation allowed the illegitimate (from the Eóganacht perspective) but militarized Dál Cais to attempt to seize the provincial kingship. However, Mathgamain was never fully recognized and was opposed throughout his career in the 960s and 970s by Máel Muad mac Brain, a semi-outsider from the Cashel perspective but still a legitimate Eóganacht claimant from far south Munster. In addition to Máel Muad, the Norse king Ivar of Limerick was a threat and may have been attempting to establish some overlordship in the province or a region of it himself, with the Cogad Gaedel re Gallaib even asserting he actually achieved this until routed by Mathgamain in the celebrated Battle of Sulcoit in 967. This victory was not decisive however and eventually there grew up a brief alliance of sorts between Mathgamain, Máel Muad and others to drive the Norse "soldiers" or "officials" out of Munster and destroy their Limerick fortress in 972.[7] But the two Gaelic claimants were soon back to fighting and the fortuitous capture of Mathgamain in 976 by Donnubán mac Cathail allowed him to be effortlessly dispatched or murdered by Máel Muad, who would now rule as king of Cashel for two years.

But the Dál Cais remained a powerful force and Brian quickly proved to be as fine a commander of armies as his brother. After first dispatching the already much weakened Ivar in 977, he challenged Máel Muad in 978 and defeated him in the fateful Battle of Belach Lechta, after which all the Eóganachta were no longer viable at the provincial level and Brian and the Dál Cais now enjoyed the overlordship, although not the traditional kingship of the province, which was based on lineage. Either soon before or soon after his victory over Máel Muad, Brian routed Donnubán and the remainder of the Norse army in the Battle of Cathair Cuan, there probably slaying the last of Ivar's sons and successor Aralt. He then allowed some of the Norse to remain in their settlement, but they were wealthy and now central to trade in the region, with a fleet of great value.

Cian, the son of his brother Mathgamain's sworn enemy Máel Muad, later became a faithful ally of Brian and served under him in a number of campaigns.

Extending authority[edit | edit source]

Having established unchallenged rule over his home Province of Munster, Brian turned to extending his authority over the neighboring provinces of Leinster to the east and Connacht to the north. By doing so, he came into conflict with High King Máel Sechnaill mac Domnaill whose power base was the Province of Meath. For the next fifteen years, from 982 to 997, High King Máel Sechnaill repeatedly led armies into Leinster and Munster, while Brian, like his father and brother before him, led his naval forces up the Shannon to attack Connacht and Meath on either side of the river. He suffered quite a few reverses in this struggle, but appears to have learned from his setbacks. He developed a military strategy that would serve him well throughout his career: the coordinated use of forces on both land and water, including on rivers and along Ireland's coast. Brian's naval forces, which included contingents supplied by the Hiberno-Norse cities that he brought under his control, provided both indirect and direct support for his forces on land. Indirect support involved a fleet making a diversionary attack on an enemy in a location far away from where Brian planned to strike with his army. Direct support involved naval forces acting as one arm in a strategic pincer, the army forming the other arm.

In 996 Brian finally managed to control the province of Leinster, which may have been what led Máel Sechnaill to reach a compromise with him in the following year. By recognising Brian's authority over Leth Moga, that is, the Southern Half, which included the Provinces of Munster and Leinster (and the Hiberno-Norse cities within them), Máel Sechnaill was simply accepting the reality that confronted him and retained control over Leth Cuinn, that is, the Northern Half, which consisted of the Provinces of Meath, Connacht, and Ulster.

Precisely because he had submitted to Brian's authority, the King of Leinster was overthrown in 998 and replaced by Máel Morda mac Murchada. Given the circumstances under which Máel Morda had been appointed, it is not surprising that he launched an open rebellion against Brian's authority. In response, Brian assembled the forces of the Province of Munster with the intention of laying siege to the Hiberno-Norse city of Dublin, which was ruled by Máel Morda's ally and cousin, Sigtrygg Silkbeard. Together Máel Morda and Sigtrygg determined to meet Brian's army in battle rather than risk a siege. Thus, in 999, the opposing armies fought the Battle of Glen Mama. The Irish annals all agree that this was a particularly fierce and bloody engagement, although claims that it lasted from morning until midnight, or that the combined Leinster-Dublin force lost 4,000 killed are open to question. In any case, Brian followed up his victory, as he and his brother had in the aftermath of the Battle of Sulcoit thirty-two years before, by capturing and sacking the enemy's city. Once again, however, Brian opted for reconciliation; he requested Sigtrygg to return and resume his position as ruler of Dublin, giving Sigtrygg the hand of one of his daughters in marriage, just as he had with the Eoganacht King, Cian. It may have been on this occasion that Brian married Sigtrygg's mother and Máel Morda's sister Gormflaith, the former wife of Máel Sechnaill.

The struggle for Ireland[edit | edit source]

Brian made it clear that his ambitions had not been satisfied by the compromise of 997 when, in the year 1000, he led a combined Munster-Leinster-Dublin army in an attack on High King Máel Sechnaill mac Domnaill's home province of Meath. The struggle over who would control all of Ireland was renewed. Máel Sechnaill's most important ally was the King of Connacht, Cathal mac Conchobar mac Taidg (O'Connor), but this presented a number of problems. The Provinces of Meath and Connacht were separated by the Shannon River, which served as both a route by which Brian's naval forces could attack the shores of either province and as a barrier to the two rulers providing mutual support for each other. Máel Sechnaill came up with an ingenious solution; two bridges would be erected across the Shannon. These bridges would serve as both obstacles preventing Brian's fleet from traveling up the Shannon and as a means by which the armies of the Provinces of Meath and Connacht could cross over into each other's kingdoms.

The Annals state that, in the year 1002, Máel Sechnaill surrendered his title to Brian, although they do not say anything about how or why this came about. The Cogadh Gaedhil re Gallaibh provides a story in which Brian challenges High King Máel Sechnaill to a battle at the Hill of Tara in the province of Meath, but the High King requests a month long truce so that he can mobilise his forces, which Brian grants him. But Máel Sechnaill fails to rally the regional rulers who are nominally his subordinates by the time the deadline arrives, and he is forced to surrender his title to Brian. There have been some doubts expressed about this explanation, given Brian's style of engaging in war; if he had found his opponent at a disadvantage it is most likely he would have taken full advantage of it rather than allowing his enemy the time to even the odds. Also, given the length and intensity of the struggle between Máel Sechnaill and Brian, it seems unlikely that the High King would surrender his title without a fight.

There have been some doubts about whether the fight occurred and what the particular circumstances were surrounding the fight. However it is generally accepted that in 1002 Brian became the new High King of Ireland.

Unlike some who had previously held the title, Brian intended to be High King in more than name only. To accomplish this he needed to impose his will upon the regional rulers of the only province that did not already recognise his authority, Ulster. Ulster's geography presented a formidable challenge; there were three main routes by which an invading army could enter the province, and all three favored the defenders. Brian first had to find a means of getting through or around these defensive 'choke points', and then he had to subdue the fiercely independent regional Kings of Ulster. It took Brian ten years of campaigning to achieve his goal which, considering he could and did call on all of the military forces of the rest of Ireland, indicates how formidable the Kings of Ulster were. Once again, it was his coordinated use of forces on land and at sea that allowed him to triumph; while the rulers of Ulster could bring the advance of Brian's army to a halt, they could not prevent his fleet from attacking the shores of their kingdoms. But gaining entry to the Province of Ulster brought him only halfway to his goal. Brian systematically defeated each of the regional rulers who defied him, forcing them to recognise him as their overlord.

First High King of the Irish[edit | edit source]

It was during this process that Brian pursued an alternate means of consolidating his control, not merely over the Province of Ulster, but over Ireland as a whole. In contrast to its structure elsewhere, the Roman Catholic Church in Ireland was centered, not around the bishops of dioceses and archbishops of archdioceses, but rather around monasteries headed by powerful abbots who were members of the royal dynasties of the lands in which their monasteries resided. Among the most important monasteries was Armagh, located in the Province of Ulster. Brian's advisor, Maelsuthain O'Carroll, documented in the 'Book of Armagh' that, in the year 1005, Brian donated twenty-two ounces of gold to the monastery and declared that Armagh was the religious capital of Ireland to which all other monasteries should send the funds they collected. This was a clever move, for the supremacy of the monastery of Armagh would last only so long as Brian remained the High King. Therefore, it was in the interest of Armagh to support Brian with all their wealth and power. It is interesting that Brian is not referred to in the passage from the 'Book of Armagh' as the 'Ard Rí' —that is, High-King— but rather he is declared "Imperator Scottorum," or "Emperor of the Irish" ("Scottorum" then being the common Late Latin term for the Irish: Ireland was usually referred to in Latin as "Scotia Major" while Scotland was referred to as "Scotia Minor").

Though it is only speculation, it has been suggested that Brian and the Church in Ireland were together seeking to establish a new form of kingship in Ireland, one that was modelled after the kingships of England and France, in which there were no lesser ranks of regional Kings – simply one King who had (or sought to have) power over all in a unitary state. In any case, whether as High King or Emperor, by 1011 all of the regional rulers in Ireland acknowledged Brian's authority. No sooner had this been achieved than it was lost again.

Máel Mórda mac Murchada of Leinster had only accepted Brian's authority grudgingly and in 1012 rose in rebellion. The Cogadh Gaedhil re Gallaibh relates a story in which one of Brian's sons insults Máel Morda, which leads him to declare his independence from Brian's authority. Whatever the actual reason was, Máel Morda sought allies with which to defy the High-King. He found one in a regional ruler in Ulster who had only recently submitted to Brian. Together they attacked the Province of Meath, where the former High King Máel Sechnaill sought Brian's help to defend his Kingdom. In 1013 Brian led a force from his own Province of Munster and from southern Connacht into Leinster; a detachment under his son, Murchad, ravaged the southern half of the Province of Leinster for three months. The forces under Murchad and Brian were reunited on 9 September outside the walls of Dublin. The city was blockaded, but it was the High King's army that ran out of supplies first, so that Brian was forced to abandon the siege and return to Munster around the time of Christmas.

Battle of Clontarf[edit | edit source]

Máel Morda was aware that the High King would return to Dublin in 1014 to try once more to defeat him. He may have hoped that by defying Brian, he could enlist the aid of all the other regional rulers Brian had forced to submit to him. If so, he had been sorely disappointed; while the entire Province of Ulster and most of the Province of Connacht failed to provide the High King with troops, they did not, with the exception of a single ruler in Ulster, provide support for Máel Morda either. His inability to obtain troops from any rulers in Ireland, may explain why Máel Morda sought to obtain troops from rulers outside of Ireland. He instructed his subordinate and cousin, Sigtrygg, the ruler of Dublin, to travel overseas to enlist aid.

Sigtrygg sailed to Orkney, and on his return stopped at the Isle of Man. These islands had been seized by the Vikings long before and the Hiberno-Norse had close ties with Orkney and the Isle of Man. There was even a precedent for employing Norsemen from the isles; they had been used by Sigtrygg's father, Amlaíb Cuarán, in 980, and by Sigtrygg himself in 990. Their incentive was loot, not land. Contrary to the assertions made in the Cogadh Gaedhil re Gallaibh, this was not an attempt by the Vikings to reconquer Ireland. All of the Norsemen, both the Norse-Gaels of Dublin and the Norsemen from the Isles, were in the service of Máel Morda. It should be remembered that the High King had 'Vikings' in his army as well; mainly the Hiberno-Norse of Limerick (and probably those of Waterford, Wexford, and Cork as well), but, according to some sources, a rival gang of Norse mercenaries from the Isle of Man. Essentially this could be characterised as an Irish civil war in which foreigners participated as minor players.[8]

Along with whatever troops he obtained from abroad, the forces that Brian mustered included the troops of his home Province of Munster, those of Southern Connacht, and the men of the Province of Meath, the latter commanded by his old rival Máel Sechnaill mac Domnaill. He may have outnumbered Máel Morda's army, since Brian felt secure enough to dispatch a mounted detachment under the command of his youngest son, Donnchad, to raid southern Leinster, presumably hoping to force Máel Morda to release his contingents from there to return to defend their homes. Unfortunately for the High King, if he had had a superiority in numbers it was soon lost. A disagreement with the King of Meath resulted in Máel Sechnaill withdrawing his support (Brian sent a messenger to find Donnchad and ask him to return with his detachment, but the call for help came too late). To compound his problems, the Norse contingents, led by Sigurd Hlodvirsson, Earl of Orkney and Brodir of the Isle of Man, arrived on Palm Sunday, 18 April. The battle would occur five days later, on Good Friday.[9]

The fighting took place just north of the city of Dublin, at Clontarf (now a prosperous suburb). It may well be that the two sides were evenly matched, as all of the accounts state that the Battle of Clontarf lasted all day. Although this may be an exaggeration, it does suggest that it was a long, drawn-out fight.

There are many legends concerning how Brian was killed, from dying in a heroic man-to-man combat to being killed by the fleeing Viking mercenary Brodir while praying in his tent at Clontarf.[10] After his death, his body was taken to Swords Co. Dublin to be waked and then on to Armagh to be buried. His tomb is said to be in the north wall of St. Patrick's Cathedral in the city of Armagh.[11]

Historical view[edit | edit source]

The popular image of Brian—the ruler who managed to unify the regional leaders of Ireland so as to free the land from a 'Danish' (Viking) occupation—originates from the powerful influence of a work of 12th century propaganda, Cogadh Gaedhil re Gallaibh (The War of the Irish with the Foreigners) in which Brian takes the leading role. This work is thought to have been commissioned by Brian's great-grandson, Muirchertach Ua Briain, as a means of justifying the Ua Briain claim to the High-Kingship, a title upon which the Uí Neill had had a near-monopoly.

The influence of this work, on both scholarly and popular authors, cannot be exaggerated. Until the 1970s most scholarly writing concerning the Vikings' activities in Ireland, as well as the career of Brian Boru, accepted the claims of Cogadh Gaedhil re Gallaibh at face value.

Brian did not free Ireland from a Norse (Viking) occupation, simply because it was never conquered by the Vikings. In the last decade of the 8th century, Norse raiders began attacking targets in Ireland and, beginning in the mid-9th century, these raiders established the fortified camps that later grew into Ireland's first cities: Dublin, Limerick, Waterford, Wexford, and Cork. Within only a few generations, the Norse citizens of these cities had converted to Christianity, intermarried with the Irish, and often adopted the Irish language, dress and customs, thus becoming what historians refer to as the 'Hiberno-Norse'. Such Hiberno-Norse cities were fully integrated into the political scene in Ireland long before the birth of Brian. They often suffered attacks from Irish rulers, and made alliances with others. Rather than conquering Ireland, the Vikings, who initially attacked and subsequently settled in Ireland, were, in fact, assimilated by the Irish.[12]

Wives and children[edit | edit source]

Brian's first wife was Mór, daughter of the king of Uí Fiachrach Aidne of Connacht. She is said to have been the mother of his sons Murchad, Conchobar and Flann. Later genealogies claimed that these sons left no descendants, although in fact Murchad's son Tadc is recorded as being killed at Clontarf along with his father and grandfather.[13]

Echrad daughter of the king of Uí Áeda Odba, an obscure branch of the southern Uí Néill, was the mother of Tadc, whose son Toirdelbach and grandson Muirchertach rivalled Brian in power and fame.[14]

Brian's most famous marriage was with Gormflaith, sister of Máel Mórda of Leinster. Donnchad, who had his half-brother Tadc killed in 1023 and ruled Munster for forty years thereafter, was the result of this union.[15]

Brian had a sixth son, Domnall. Although he predeceased his father, Domnall apparently had at least one surviving child, a son whose name is not recorded. Domnall may perhaps have been the son of Brian's fourth known wife, Dub Choblaig, who died in 1009. She was a daughter of King Cathal mac Conchobar mac Taidg of Connacht.[16]

Brian had at least three daughters but their mothers are not recorded. Sadb, whose death in 1048 is recorded by the Annals of Innisfallen, was married to Cian, son of Máel Muad mac Brain. Bé Binn was married to the northern Uí Néill king Flaithbertach Ua Néill. A third daughter, Sláni, was married to Brian's stepson Sitric of Dublin.[17]

According to Njal's Saga, he had a foster-son named Kerthialfad.[18]

Cultural heritage[edit | edit source]

  • The descendants of Brian were known as the Ui Briain (O'Brien) clan, hence the surnames Ó Briain, O'Brien, O'Brian etc. "O" was originally Ó which in turn came from Ua, which means "grandson", or "descendant" (of a named person). The prefix is often anglicised to O', using an apostrophe instead of the Irish síneadh fada: "´". The O'Briens subsequently ranked as one of the chief dynastic families of the country (see Chiefs of the Name).

In popular culture[edit | edit source]

Morgan Llywelyn has written a novelization of Brian's life called simply Lion of Ireland. The sequel, Pride of Lions, tells the story of his sons, Donough and Teigue, as they vie for his crown.

His name is remembered in the title of one of the oldest tunes in Ireland's traditional repertoire: "Brian Boru's March". It is still widely played by traditional Irish musicians.

Edward Rutherfurd affords Brian Boru a chapter in his historical fiction, The Princes of Ireland: The Dublin Saga. His version supports the contention that Brian died while praying in his tent.

The second volume of Brian Wood's Vertigo graphic novel series Northlanders is set against a backdrop of Viking "occupation" of Ireland, including the Battle of Clontarf.

In the Disney film Darby O'Gill and the Little People, King Brian Conners of the Leprechauns shows Darby the sword Brian Boru used to drive out the Danes (Vikings).

Professional wrestler Sheamus has referenced Brian several times while cutting promos as part of his character, King Sheamus.

The story of Brian Boru's final battle and death is told in Frank Delaney's novel Ireland.

In the 1949 novel Silverlock by John Myers Myers the death of Brian Boru is described from the main character's viewpoint.

The character of Miles O'Brien in the science fiction television show Star Trek: Deep Space Nine says that he is a direct descendant of Brian Boru in the 4th season episode "Bar Association".
