Ireland consisted of many semi-independent túatha, and during the whole period attempts were made by various factions to gain political control over the whole of the island. For the first two centuries of our period this was mainly a rivalry between High Kings of Ireland from the northern and southern branch of the Uí Néill

, great advances have been made in the understanding of the physical character of the towns established in this period.

The first part of the period from 800 to 1014 is well-studied; the "Viking age" has attracted the interest of historians for quite some time. The period between 1014 and 1169 has received less attention. In the words of Sean Duffy, this period
has – historiographically speaking – fallen between two stools. Historians of early medieval Ireland, seeking to conclude their narratives on a high note, have traditionally done so after recounting the death of the famous high-king Brian Bórama (Boru) at the battle of Clontarf in 1014. On the other hand, historians of later medieval Ireland generally choose to begin proceedings with the English invasion of the 1160s. Eleventh- and early twelfth-century Ireland has, therefore, often assumed the character of a snappy epilogue or a lengthy prologue.See also McNeill, "Archaeology", "The 150 years before 1200 have been lost, between the assumptions that life was a continuation of the fifth through eighth-century world and that the incursion of English lords marked a fundamental change throughout Ireland."


In trying to interpret the history of early Ireland, one of the most frequently asked questions addressed by historians is how early it is possible to speak of an Irish nation, a natio encompassing the whole island of Ireland. Early poet-historians like Flann Mainistrech
Flann Mainistrech

s and G.H. Orpen came to opposite conclusions analysing the same period. Orpen saw an anarchic country still in ‘a tribal state’; he could see no natio, no wider community in Ireland than the tribe. MacNeill stressed the reality of the high-kingship of Ireland and the existence of many of those institutions of government which Orpen found wanting, and claimed that Irish law had a national character.

Nature of the written sources

A large body of contemporary and near-contemporary material on early medieval Ireland has survived. From the titles of works mentioned in these sources, it is clear that a great deal of additional material has now been lost. The surviving materials usually exist in the form of much later copies, and it is only from comparison of the various texts that the original documents can be reconstructed.

Áed Oirdnide of the Cenél nEógain branch of the Northern Uí Néill became King of Tara in 797, after the death of his successor, father-in-law and political rival Donnchad Midi. This followed the classic Uí Néill political arrangement, where over-kingship alternated regularly between Cenél nEógain and Clann Cholmáin of the Southern Uí Néill. During his reign he campaigned in Mide, Leinster and Ulaid to assert his authority, though unlike Donnchad he did not campaign in Munster.

This brought him in conflict with Feidlimid however, and in 838 a conference (rígdál mór - "great royal meeting") between Niall and Feidlimid was held.Hudson, Niall Caille. According to Hudson, "Any agreement made there has not survived, although the report of the meeting from a Munster chronicle with a bias towards the southern prince claims that Niall submitted to Feidlimid, while a contemporary northern chronicle has no report of the proceedings." This meeting did not result in any lasting peace though, in 840 Feidlimid led an army into Mide and encamped at Tara and thereby challenged the Uí Néill also in the north. In 841 however, Feidlimid was routed in battle by Niall in Leinster. His successors in the south would not be able to challenge the north again to this extent until some 150 years later.

Shifting alliances and struggle for power

A significant new trait from the middle of the 9th century was that the Norse now also entered alliances with various Irish rulers. Cerball mac Dúnlainge

, however, Cerball and Áed appeared as allies in Leinster.

Máel Sechnaill had more success as high-king than his predecessors Niall Caille and Conchobar Donnchada in dealing with the south, and forced Munster into submission in 858 and as noted above Osraige in 859. He also asserted control over Ulaid, Leinster and Connacht, and was in his obituary in the Annals of Ulster described as ri h-Erenn uile, king of all Ireland. The last years of his reign he had however experienced serious opposition from his Uí Néill kinsmen of Ailech and Brega, allied with the Norse of Dublin. Byrne
Francis John Byrne
Francis John Byrne is an Irish historian.Born in Shanghai where his father, a Dundalk man, captained a ship on the Yellow River, Byrne was evacuated with his mother to Australia on the outbreak of World War II...

 notes: "Máel Sechnaill's unprecedented success in achieving the high-kingship of all Ireland was marred by the chronic complaint of Irish politics: having united the Ulaid, Munster, Osraige, Connacht and Leinster, he was attacked at the end of his reign by a combination of Uí Néill kings."

Áed Findliath was king of Ailech and the leading king within the Northern Uí Néill. After the death of Máel Sechnaill he is counted in the regal lists as high king, following the established scheme where this alternated between Cenél nEógain in the north and Clann Cholmáin of Mide. His kingship was disputed though, and he did not come close to being an actual king over Ireland. He could count some successes against the Norse however, most notably burning all the Norse longports in the north in 866. Áed seem to have used the opportunity while Olaf was involved in warfare in Pictland, presumably bringing a large contingent of the Norse forces in Ireland with him. The Vikings never managed to establish permanent settlements in the north. Ó Corráin

 observes: "Ironically, [Áed Findliath's] success may have held back the economic development of the north and ultimately prevented the growth of port towns like those on the east and south coasts, on which the Leinster and Munster kings subsequently depended for much of their wealth."

Waterford (914), Cork (c.915), Dublin (917), Wexford (c.921) and Limerick (922)." Significant excavations in Dublin and Waterford in the 20th century has unearthed much of the Viking heritage of those cities.

The Vikings founded many other coastal towns, and after several generations of coexistence and intermarriage a group of mixed Irish and Norse ethnic background arose (often called Norse-Gaels

 or Hiberno-Norse). This Norse influence is reflected in the Norse-derived names of many contemporary Irish kings (e.g. Magnus, Lochlann or Sitric), and DNA evidence in some residents of these coastal cities to this day. A genetics paper in 2006 by Dr Brian McEvoy found that most men with Irish-Viking surnames carried typically Irish genes. This suggests that Viking settlements may have had a Scandinavian elite but with most of the inhabitants being indigenous Irish.

Niall Glúndub marched on Dublin in September 919, but his forces were met by Sihtric at Islandbridge and suffered a decisive defeat, with Niall and numerous other Irish leaders among the casualties. Dublin was secured for the Norse, and in 920 Sitric left for York and following Ragnalls death succeeded him as ruler there in 921. Their kinsman Gofraid

During a raid at Armagh in 921 Gofraid "...spared the prayerhouses... ...and the sick from destruction", considerations never taken by the raiders of the previous century. Another was the intense campaigns led by Dublin in eastern Ulster from 921 to 927, where the purpose seem to have been conquest in order to create a Scandinavian kingdom like the one on the eastern side of the Irish sea.

Dublins ambitions in Ulster was halted by a series of defeats inflicted upon the them by Muirchertach mac Néill

Gofraid retook the city, but the struggle between Limerick continued well after Gofraids death in 934. He was succeeded by his son, Amlaíb, who inflicted a decisive defeat on Limerick in 937.

, later famously known as Brian Boru.

Brian quickly established himself as the most powerful ruler in Munster, defeating the Norse Limerick in 977 and the Eóganachta the following year. Having gained control over Munster, he tried to extend his authority by raiding Osraige in 982 and 983, and also, according to the annals of Innisfallen, entering an alliance with the Norse Waterford

, and they were defeated by Glúniairn and Máel Sechnaill.

Máel Sechnaill obviously perceived Brian as a threat, and as early as 982 raided Munster and the territory of the Dal gCais. The next two decades saw more or less constant warfare between them, mostly with Leinster as their battleground. Even if Brian never defeated Máel Sechnaill in battle, Brians and Munsters influence was growing on the expense of Máel Sechnaill and the Southern Uí Néill. In 997 Máel Sechnaill was forced to acknowledge Brians authority over the south of Ireland, and they formally divided Ireland according to the traditional scheme of Leath Cuinn and Leath Moga

 as ruler of Dublin after he had formally submitted to Brian by handing over hostages.

In 1000, Brian turned against Máel Sechnaill, and by 1002 he had forced Máel Sechnaill to submit to him, and now claimed kingship over the whole of Ireland. In the following decade, there was several campaigns in the north to force the Ulaid and the Northern Uí Néill into submission as well. Even if faced with multiple rebellions, both in the north and in Leinster, by 1011 had received submission from every major regional king in Ireland, and thus earned the recognition by historians as the first real king of Ireland. During his visit to Armagh in 1005, he had his secretary add a note to the Book of Kells

 where he is proclaimed as Imperator Scottorum (emperor of the Irish). According to Bart Jaski, "This can be regarded as a claim that he ruled both the Irish and the Norse in Ireland, and may even imply suzerainty over the Gaels of Scotland". In his obituary in the Annals of Ulster he is styled as "over-king of the Irish of Ireland, and of the foreigners and of the Britons, the Augustus of the whole of north-west Europe".

High Kings with Opposition (1022 onwards)

Donnchad mac Brian styled himself as 'King of Ireland' after the death of Máel Sechnaill, but was not recognised as such. A glossing of Baile In Scáil lists Flaitbertach Ua Néill as high king, but he proved unable even to control the north of Ireland. Neither was anyone else able to make a recognised claim for kingship over all of Ireland, according to Byrne, "what distinguished the great interregnum of 1022–72 from other periods in Irish history is is at is was recognised as such by contemporary observers"

 had written Ríg Themra tóebaige iar tain, a regnal poem on the Christian (Uí Néill) kings of Tara some time between 1014 and 1022. When he wrote in 1056 he evidently did not know any high-king of Ireland, and instead lists a number of kings of the day: Conchobar, Áed, Garbith, Diarmait, Donnchad and two Nialls. According to Byrne, these are Conchobar Ua Maíl Schechnaill of Mide, Áed Ua Conchobair

 of Ulaid.

The term rí Érenn co fressarba ("High kings with opposition") was used from the 12th century. According to Byrne, "it could be argued that the 'high kings with opposition' met with opposition precisely because they tried to become kings of Ireland in a real sense. They were not less successful than their predecessors, but only seemed so in the light of the teaching of the schools". Following a similar line of reasoning, Byrne suggests that the focus from historians on the decline of the Uí Néill in the 11th century, may be a "tribute to the success of their own propaganda". After Brian, the previous Uí Néill monopoly of high kingship as described in poems and chronicles, was anyway broken for good. The Cenél nEógain suffered from internal faction, and this allowed the Ulaid, under Niall mac Eochada to expand their influence. Niall and Diarmait mac Maíl na mBó became allies, and effectively controlled the whole east coast of Ireland. This alliance helped to make it possible for Diarmait to take direct control of Dublin in 1052. Unlike Máel Sechnaill in 980 or Brian in 999, he wasn't content just looting the city and expelling the Hiberno-Norse ruler (Echmarcach mac Ragnaill

); in an unprecedented move he assumed the kingship 'of the foreigners' (ríge Gall) himself.

Reform of the Irish Church

There were major reforms in the Irish church during the 12th century. These reforms have been generally been interpreted as a reaction to previous secularisation, but could also be seen as a continuous development. The reforms had consequences for, and were influenced by, relations within the church as well as secular politics.

Before the 11th century the church in Ireland was monastic, with bishops residing at monasteries and without a permanent diocesan

 ever made direct primatial claims for Canterbury in relation to the Irish church.

Toirdelbach appears to have responded favourably to this, and convened a synod in Dublin in 1080 - the outcome of this synod is not known. Toirdelbach may have seen cooperation with Canterbury as a way to reduce the influence from Armagh, traditionally dominated by Cenél nEógain, within the church in Ireland.

s Historia Novorum is subscribed by bishops from Munster, Mide, Dublin and Leinster. Gilla Espaic, the first bishop of Limerick, was however not consecrated in Canterbury, but probably by Cellach  of Armagh.Gilla received a letter from Anselm congratulating him on his elevation to the see of Limerick, and there was no suggestion that Anselm felt Canterbury had been slighted or ought to have been involved. Flanagan, p. 915.

The first of the four main synods main associated with the church reforms of the 12th century took place in Cashel in 1101, at the instigation of Muirchertach Ua Briain. How many who actually attended this synod is not known, but some of its decrees have been preserved. There is a decree on simony, on prohibition for laymen to become airchinnig (heads of ecclesiastical establishments) and finally a decree that defines what relationships are considered to be incestuous. None of these decrees are radical, but they are generally interpreted to be in line with the Gregorian reform

 and attended by fifty bishops, three hundred priests and over three thousand laymen, marked the transition of the Irish church from a monastic to a diocesan and parish-based church. It established two provinces, with archbishoprics at Armagh and Cashel, and prominence given to Armagh, making Cellach the primate of the church in Ireland. Each province consisted of twelve territorial dioceses. The see of Dublin was not included, as this was under primacy from Canterbury,The see of Waterford however, where the incumbent bishop Máel Ísu Ua hAinmire also had been consecrated in, and taken vows of obedience to, Canterbury, was moved to Lismore, and Máel Ísu chosen as the first archbishop of Cashel. but a place was left open for it, in the sense that only eleven dioceses were declared under Cashel.

Gilla, Cellach and Cellach's successor Máel Máedóc Ua Morgair, better known as St. Malachy, drove the reform process onwards. Malachy, in close cooperation with Donnchad Ua Cerbaill, king of Fernmag/Airgialla, established the first Irish Cistercian house at Mellifont in 1142, and also facilitated the first Augustinian community of the Arrouaisian observance. Malachy used these as agencies of monastic reform within the Irish church. Malachy resigned as archbishop of Armagh in 1136, but was appointed native papal legate to Ireland by Innocent II

The main challenge must have been to reach an accommodation with Dublin, and Tairrdelbach Ua Conchobair, presently the most powerful king in Ireland, was eager to increase Connacht influence on the church.
