Armies and Intercession – Emerald Archives

The surviving Irish annals present 1109 as a year of campaigning, hostage-taking, ecclesiastical intervention and environmental anxiety. Their entries are terse and sometimes reflect the viewpoints of particular churches or dynasties, yet several independent compilations agree on the year’s central developments. Muirchertach Ua Briain of Munster supported an attack by Murchad Ua Máel Sechlainn, king of Mide, upon Bréifne; Domnall Ua Lochlainn mobilised the northern kingdoms; and Cellach, successor of Patrick at Armagh, intervened to prevent the rival overkings from fighting. Local warfare continued despite that truce. Alongside these political events, the annalists recorded heavy rain, religious fasts, an abundance of apples and, in some districts, destructive mice in the cornfields.

Rival Claims to Supremacy

No single ruler governed Ireland as a unified state. Muirchertach Ua Briain, great-grandson of Brian Bóruma, possessed extensive influence in Munster and over several southern and central kingdoms. Domnall Ua Lochlainn, king of Ailech and leader of Cenél nÉogain, dominated much of the north. Each could assemble coalitions, demand hostages and claim a standing approaching the kingship of Ireland, but neither could compel permanent obedience throughout the island. The language of high-kingship therefore requires care: contemporary authority depended less upon a fixed national office than upon military reach, alliances, tribute and recognition by lesser rulers.

Mide was especially important because it lay between the northern and southern spheres. Its king, Murchad Ua Máel Sechlainn, had gained the kingship only a few years earlier and was closely tied to Ua Briain, whose daughter Mór he married. The alliance gave Muirchertach a dependable associate in the midlands and gave Murchad the backing of one of Ireland’s most formidable rulers. In 1109 their immediate target was Bréifne, the expanding kingdom of the Uí Ruairc along Mide’s northern frontier.

The Bréifne Campaign

The Annals of Ulster, the Annals of Loch Cé and the Four Masters all record that Muirchertach Ua Briain brought an army to assist Murchad Ua Máel Sechlainn and plundered part of Uí Briúin territory. The fullest later account says that men from Munster, Mide and Connacht advanced into Tír Briúin Bréifne, carried away cattle and prisoners, and entered the islands of Loch Uachtair, now Lough Oughter in County Cavan, to seize people sheltering there. Such islands and crannógs offered defensible refuges within a landscape of lakes, woods and wetlands, but the entry indicates that they did not provide complete protection against an organised royal host.

The Munster-oriented Annals of Inisfallen describe the operation in especially vivid terms. Ua Briain searched Dub-Bréifne’s recesses and fastnesses and removed cattle, valuables and other booty. Yet the same source admits that he returned without securing a hostage or pledge from the Bréifne ruler whom it calls In Gilla Srónmael, apparently Aed Ua Ruairc. This qualification is significant. Spoils demonstrated military power and rewarded an army, but hostages represented acknowledged submission. Ua Briain could devastate the countryside without settling the political dispute in his favour.

The campaign’s human cost extended beyond named nobles. Cattle were central to wealth, food production, rents and aristocratic hospitality, so their seizure could impoverish farming households as well as enrich a victorious king. Captives might be held for ransom, distributed among followers or taken into servitude. The forces also required provisions while moving through friendly and hostile territories. An army’s arrival consequently placed pressure on stores of grain, livestock and drink even where no battle occurred.

Bréifne Strikes Back

The Uí Ruairc response quickly exposed the limits of Murchad’s success. Aed Ua Ruairc entered Murchad Ua Máel Sechlainn’s encampment twice and inflicted slaughter. The annalists interpreted these attacks through a religious lens, saying that they occurred through the curse of Patrick’s community. Murchad had reportedly raided Fir Rois, killed its lord Ua Finn and violated the protection of Cellach and the Staff of Jesus, one of Armagh’s most revered insignia. The statement that divine vengeance followed expresses an ecclesiastical judgement: a king who disregarded sacred guarantees could be portrayed as losing not merely through poor tactics, but through sin.

The Four Masters also assign the burning of Ardbraccan, with its churches, to the Uí Briúin during this conflict. People were killed and captives removed. Ardbraccan was an important ecclesiastical settlement in Mide, and its destruction illustrates how little immunity a religious centre might possess when it stood within a contested frontier. Churches could be places of worship, learning and sanctuary, but they also held food, livestock, precious objects and dependent populations. Attacking one was both materially profitable and politically provocative.

Peace at Sliab Fuait

While Ua Briain was active in the midlands, Domnall Ua Lochlainn led the forces of northern Ireland towards Sliab Fuait, in the borderlands near Armagh. The two great coalitions were therefore moving within dangerous reach of one another. Cellach, successor of Patrick, intervened and negotiated a peace for one year between Ua Briain and Ua Lochlainn. The annals do not describe a formal battle, and the agreement should not be mistaken for a lasting reconciliation. It was a limited truce that prevented an immediate collision while leaving both rulers free to pursue other objectives.

Cellach’s mediation reveals the growing public authority of Armagh. He was not simply the head of one monastic community. He travelled between kingdoms, collected ecclesiastical dues, carried Patrick’s relics and insignia, and acted as a broker whose protection rulers were expected to respect. His work in 1109 belongs to the broader movement of Irish church reform that was gathering strength before the Synod of Ráith Bressail in 1111. Older institutions based on hereditary abbatial families and saintly communities were increasingly interacting with a more episcopal and territorially organised vision of church government.

Submission in Ulster

Once the year’s peace had been arranged, Ua Lochlainn’s coalition turned against the Ulaid. Cenél nÉogain and Cenél Conaill joined other northern forces at Mag Uí Bresail to confront the Ulaid positioned in Mag Coba, probably in the modern County Down area. The Ulaid avoided battle by surrendering three hostages selected by their opponents. Hostages were not merely prisoners: they embodied a ruler’s promise to provide tribute, military cooperation or good behaviour. Their surrender marked Ua Lochlainn’s effective superiority in that encounter.

Other northern entries show a more fragmented pattern of violence beneath the large royal coalitions. The Uí Méith and the men of Fir Manach joined in a slaughter of the Uí Bresail and their king, Dartin. Later, the Uí Bresail and Uí Echach killed Goll Bairche, king of Uí Méith, together with some of his allies. These notices are difficult to reconstruct as a single campaign, but they demonstrate that provincial politics consisted of overlapping local feuds and alliances. A truce between two overkings could restrain their principal armies without pacifying every subordinate dynasty.

Churchmen and Learning

Several prominent clerics died during the year. Máel Ísu Ua Cuillen was remembered as a noble bishop of northern Ireland. Aengus Ua Domnalláin, chief confessor and senior of the community of Colum Cille, died at Kells. Flaithbertach Ua Loingsig, successor of Ciarán and a leading priest of Clonmacnoise, also died, while the Annals of Inisfallen record the death of Gilla Pátraic Ua Selbaig, head of the community associated with St Fin Barre at Cork. Their titles reflect an ecclesiastical world in transition, where bishops existed alongside powerful successors of saints, confessors, scholars and administrators.

Kells and Clonmacnoise remained centres of worship, teaching, manuscript production and historical memory. Lebor na hUidre, the Book of the Dun Cow, was compiled at Clonmacnoise around this period, though it cannot be assigned specifically to 1109. Its survival illustrates the range of learning cultivated by Irish churches: biblical material stood beside vernacular narrative, poetry, genealogy and accounts of Ireland’s past. The annals themselves emerged from this literate culture, preserving political news while interpreting events according to the interests and moral expectations of religious communities.

Weather, Harvest and Daily Life

The Annals of Inisfallen report heavy rain and bad weather during the summer and autumn. Communities responded with fasting, abstinence and almsgiving in the hope that God would dispel the conditions. This is direct evidence not only for the weather but for the social response to it. Public religious observance offered a means of confronting threats that could not otherwise be controlled, while almsgiving redistributed at least some resources towards the poor.

The same annals record abundant apples, whereas the Four Masters state that mice consumed all the cornfields in certain territories. These reports need not contradict one another. Orchards might flourish while cereal crops suffered locally, and the mice were explicitly confined to unspecified districts. Most people lived in rural settlements and depended upon mixed farming. Cattle carried exceptional economic and political value, but oats, barley and other cereals remained essential, together with dairy produce, pigs, sheep, vegetables, nuts and fruit. A wet growing season, animal infestation or military raid could therefore unsettle a household’s food supply from several directions.

Ireland also contained established towns at Dublin, Waterford, Wexford, Cork and Limerick, linked by sea to Britain and wider commercial networks. Coinage, imported materials and specialised crafts circulated in these ports, although barter, livestock and precious metal continued to serve as measures of value elsewhere. The annals say little about ordinary merchants, craftspeople, farmers, herders or labourers in 1109, but their work sustained the armies, churches and royal households that dominate the written record.

An Unsettled Balance

A final, unusual death captures something of the period’s precarious aristocratic life. Domnall Ruad Mac Gilla Pátraic, king of Osraige, was killed by another youth during a game, apparently by a cast stone. No battlefield was required to create a succession crisis. By the close of 1109, Ua Briain had demonstrated his ability to penetrate Bréifne but had failed to obtain its submission; Murchad of Mide had suffered sharp retaliation; Ua Lochlainn had taken hostages from the Ulaid; and Cellach had prevented a larger war. The resulting peace was temporary, but the year showed that ecclesiastical intercession could shape politics alongside armed force.
