Abstract
In 1245, Maurice fitz Gerald, justiciar of Ireland, built Sligo Castle with Síl Muiredaig, compelling King Fedlimid Ó Conchobair of Connacht to meet much of the cost and appropriating ecclesiastical materials. The fortress strengthened lordship over strategic north-western routes. Other castles at Áth an Chip and Caisleán Suicín reflected intensified frontier militarisation. Fedlimid joined Henry III’s Welsh campaign, gaining royal recognition despite continuing Anglo-Irish pressure. Maurice was replaced by John fitz Geoffrey. Church disputes, killings, raids and successions revealed regional instability, while Elphin’s episcopal dispute reached Pope Innocent IV at Lyons. Severe snow before Christmas disrupted travel, livelihoods and supplies.

In 1244, Connacht experienced intertwined political, ecclesiastical and social crises. Cú Chonnacht Ó Raghallaigh blinded and emasculated the captive dynast Tadc Ó Conchobair, prompting King Fedlimid’s large retaliatory hosting into Breifne. At Fenagh, troops accidentally caused a foster-child’s death; compensation disputes ended when Magnus son of Muirchertach died during a flooded retreat, followed by payments in horses and silver measured by the Bell of the Kings. Tadc’s brothers died, while lords, clerics and poet Donnchad Mór Ó Dálaigh also perished. Tuam burned, Elphin’s episcopal election divided, and Dublin officials audited treasury accounts, illustrating Ireland’s overlapping Gaelic, ecclesiastical and Anglo-Irish authorities.

In 1243, Connacht and its borderlands saw political violence centred on Tadhg Ó Conchobair, grandson of Cathal Crobderg. Released by Cú Chonnacht Ó Raigillig, Tadhg seized Cormac Mac Diarmata and his own mother, Étáin, delivering her to Ó Raigillig as ransom. At Martinmas, Ó Raigillig treacherously recaptured Tadhg and killed his followers, worsening Connacht-Bréifne tensions. Raids by Cathal Ó Conchobair deepened conflict. Ecclesiastical notices record clerical deaths, overseas learning, and enlargement of Ardcarne church. Richard de Burgh died campaigning for Henry III in France. Annalistic confusion over Hugh de Lacy’s death requires caution, illustrating limitations of medieval chronology in sources.

In 1242, a great chapter at Louth, attended by the Primate of Armagh and Irish Canons Regular, ceremonially raised relics of Saint Mochta, affirming religious networks and local prestige. Donnchad Cairprech Ó Briain, king of Thomond, and his son died, enabling Conchobar’s succession. Maurice FitzGerald, justiciar, and Fedlimid Ó Conchobair campaigned in Tír Chonaill, obtaining hostages before Tadhg Ó Conchobair’s capture. Brian Ó Dubhda was killed on pilgrimage, while Sligo’s hospital changed hands. Violence persisted in Connacht and Breifne. Hugh de Lacy’s death ended his personal Ulster lordship, while Armagh’s primate travelled to England. These events reveal fragmented, interconnected authority.

In 1241, Ireland’s political map did not suddenly become simpler, but decisive events in Ulster, Connacht and the midlands altered the balance of power. The most consequential was the battle of Caimeirge, where Brian Ó Néill and the newly installed Máel Sechnaill Ó Domnaill defeated and killed Domnall Mac Lochlainn, king of Tír Eoghain. In the west, Maurice FitzGerald, justiciar of Ireland, combined a damaging raid with a short-lived peace-making expedition. Meanwhile, the arrival of Albert Suerbeer, the German-born archbishop of Armagh, with papal authority over the churches associated with St Patrick made ecclesiastical jurisdiction an urgent political question.

In 1240, one journey gave Irish politics an unusually direct connection with the court of King Henry III of England. Feidlim Ua Conchobair, king of Connacht, crossed the sea to present his case before the English king. The Annals of Connacht state plainly that he went to complain of the Galls and Gaels of Ireland: that is, of both the Anglo-Norman settlers and lords commonly called ‘Foreigners’ in Irish chronicles, and Irish opponents. The annalists say that Henry received him with great honour and that Feidlim returned safely, cheerful and satisfied. The brief notice does not preserve the arguments, concessions

In 1239, Ireland’s fragmented politics combined warfare, lordship and religious patronage. Domnall Mac Lochlainn defeated rival forces at Carnteel, regaining Tír Eógain after Anglo-Norman intervention. Maurice FitzGerald’s forces raided around Sligo, probing Ó Domnaill territory without securing lasting conquest. In Breifne, Fergal Ó Raigillig’s killing illustrated regional and dynastic conflict, though its date is disputed. Lasairfina, daughter of Cathal Crobderg Ó Conchobair and wife of Ó Domnaill, granted land at Ros Birn to Trinity Abbey on Lough Key. Cashel confirmed Dominican Dáuíd son of Cellach as archbishop. Annalistic discrepancies caution against certainty, while revealing intertwined power, land, kinship, and church.

In 1238, Anglo-Irish leaders Maurice FitzGerald and Hugh de Lacy campaigned in the north, deposing Domnall Mac Lochlainn, installing an Ó Néill claimant and taking hostages from Cenél nEógain and Cenél Conaill. In Connacht, barons extended castle building after the 1235 partition, while dynastic killings, captures and raids demonstrated insecurity. A Bréifne force plundered Cluain Coirpthe, causing deaths among pursuers. Annadown’s bell-tower was built beside Lough Corrib, though its exact form remains uncertain. Archbishop Felix Ó Ruadáin died after resigning and becoming a monk in Dublin. Overall, the annals depict contested power expressed through hostages, fortifications, violence and ecclesiastical construction.

In 1237 Fedlim mac Cathail Chrobdeirg Ua Conchobair led a Connacht coalition against rival Ua Conchobair claimants, defeating troops linked to the Justiciar at Drumrat and devastating opponents’ lands. His forces briefly controlled Magh Luirg and Lough Key, where land was granted to a Holy Trinity community, while Fedlim later executed hostages. He subsequently made peace with the Justiciar, receiving the Five King’s Cantreds free of tribute, as Irish barons began castle-building in Connacht. Church reform advanced through Archbishop Máel Muire Ó Lachtáin’s Athlone synod. Clarus Mac Máelín founded a canons’ monastery on Trinity Island, while several prominent clerics died.

In 1236, Connacht remained unstable after Anglo-Norman conquest, as Maurice FitzGerald displaced Fedlimid Ó Conchobair, who escaped northwards. FitzGerald’s forces pillaged lands, captured women and built a stronghold, while Brian Ó Conchobair ruled with foreign support. Fedlimid returned with allies and raided Rindoon’s defended settlement for cattle, but his dispersed forces were defeated. Richard de Burgh later backed him, yet warfare devastated Tuam, Mayo and surrounding districts, including churches and their food stores. Burned sanctuaries, captivity, hunger and scarcity marked the year. Ecclesiastical authority proved ineffective against violence, although Tuam’s archbishop-elect gained English and papal confirmation. No durable settlement emerged.

In 1235, Richard de Burgh and Justiciar Maurice FitzGerald led a broad Anglo-Irish army into Connacht, burning Roscommon and Elphin, raiding cattle, and disrupting communities. The expedition extended into Thomond, forcing King Donnchad Ó Briain to surrender hostages and tribute, before pursuing Fedlimid Ó Conchobair’s allies across western coastal and island regions. At Lough Key, attackers deployed ships, siege engines and a floating ram to capture the Rock, but its garrison lost it within twenty nights. Fedlimid later made peace and retained five cantreds. The campaign demonstrated lordship power, yet Connacht remained damaged, politically contested and far from securely conquered.

In 1234, Richard Marshal, earl of Pembroke and lord of Leinster, brought his rebellion against Henry III’s Poitevin advisers to Ireland. Supported by Leinster allies, he recovered positions and captured Limerick, but royalist magnates Maurice FitzGerald, Hugh de Lacy and Walter de Lacy defeated him on the Curragh of Kildare on 1 April. Wounded and detained, Marshal died at Kilkenny on 16 April and was buried there. His defeat strengthened royal authority, restored Richard de Burgh’s Connacht interests under restrictive terms, and prepared subsequent expansion. Meanwhile, fighting at Tralee demonstrated continuing conflict between settler powers and Gaelic dynasties across Ireland.

In 1233 Feidlimid mac Cathail Chrobderg Ua Conchobair regained Connacht after his coalition, assembled with Cormac Mac Diarmata at Druim Grecraige, routed and killed his cousin Áed mac Ruaidrí and leading supporters. The victory displaced Ruaidrí Ua Conchobair’s descendants, despite Anglo-Norman involvement on both sides. Annalists interpreted Áed’s defeat through alleged crimes against churches, but their accounts also record political propaganda. Feidlimid destroyed four rival castles, including Bun Gaillme and Dunamon, asserting territorial control and imposing praised order. In Breifne, Cathal Ua Ráigillig’s forces defeated William de Lacy’s raiders. Obituaries illuminate church households’ roles in landholding, hospitality, mediation and welfare.

In 1232, Connacht’s contested kingship linked local dynastic rivalry to English royal politics. Richard de Burgh released Fedlimid Ó Conchobair after his patron Hubert de Burgh’s fall, while Áed mac Ruaidrí retained a precarious restoration. De Burgh’s castle at Bun Gaillme and Adam Staunton’s at Dunamon embodied efforts to secure enduring authority. Conchobar, Áed’s son, died invading the Three Tuatha, weakening his dynasty. Elsewhere, chieftains fought, hostages were taken, crops destroyed and coastal warfare continued. Yet churches were consecrated, regular canons organised, and religious figures were praised for learning, hospitality and care, showing warfare and institution-building advancing together across Ireland.

In 1231 Richard de Burgh captured Fedlimid mac Cathail Chrobdeirg Ó Conchobair at Meelick, despite guarantees, exposing the fragility of Gaelic rulers’ alliances with Anglo-Norman power. Imprisoned in strategically placed Shannon castle, Fedlimid’s fate left Connacht contested; his release and later victory belonged to subsequent years. Annals also record Connacht’s religious and local life: deaths among ruling families, Boyle Abbey’s pilgrim connections, episcopal succession at Elphin, and Dionysius Ó Mórda’s death on Trinity Island. They note learned status, Mac Diarmata’s market project, a waterborne Breifne raid, and Ualgarc Ó Ruairc’s fatal Holy Land pilgrimage, revealing active networks amid political instability.

In 1230, Áed mac Ruaidrí Ó Conchobair’s revolt against Richard de Burgh, Mac William, intensified Connacht’s succession crisis. De Burgh assembled Anglo-Norman and Gaelic allies, advanced through Galway and Mayo, secured submissions and hostages, and defeated Donn Óc Mac Airechtaig’s forces at Fincharn. His troops devastated communities sheltering with cattle in remote terrain, causing hunger, deaths and dispossession. At Lough Key, de Burgh installed Fedlimid mac Cathail Chrobdeirg as king and expelled Áed, who sought Ó Néill’s protection in Tír Eógain. The year also recorded Áed Ó Néill’s death and obituaries illuminating ecclesiastical leadership, monastic craftsmanship and scholarship across Ireland.

In 1229, the disputed burial of Diarmait Mac Gilla Carthaig, erenach of Tibohine, exposed rivalry between Boyle’s Cistercians and Trinity’s canons, leaving his body at Drum for three days before settlement. The year also brought clerical deaths, resignations and the loss of learned canon Gerald Ó Catháin, amid Connacht’s instability after 1228. Duibessa Ó Conchobair died as a nun, while rulers of Desmond and Corcu Laígde died. Henry III granted Dublin a mayoralty and Drogheda urban liberties, disafforested lands linked with Glendalough, and Ballybeg Priory was conventionally founded. These events reveal regional institutions, succession, patronage and authority across medieval Ireland.

In 1228, Áed Ó Conchobair of Connacht was murdered in Leinster, intensifying dynastic conflict. Richard de Burgh, newly appointed justiciar, helped oversee a Connacht assembly that inaugurated Áed son of Ruaidrí at Carnfree, rejecting his elder brother Toirrdelbach. The settlement failed: warfare, cattle seizures and plunder devastated much of Connacht, causing hunger, displacement, and the flight of clergy and learned people. Elsewhere, lineage killings affected Breifne, royal administration promoted Magna Carta and land claims, and Dublin’s archiepiscopal succession became contested. Coleraine’s fortification was renewed, while Irish annalists noted Francis of Assisi’s canonisation, revealing Ireland’s wider ecclesiastical connections during the year.

In 1227, Connacht faced intensified pressure from the English lordship, dynastic rivals and regional raiders. Summoned to Dublin, King Áed mac Cathail Chrobdeirg Ó Conchobair escaped an alleged plot through William Marshal’s intervention. He subsequently captured William de Marisco and companions at Lathach Caich, attacked Athlone, and exchanged prisoners for his children, Connacht hostages and a peace. Meanwhile Geoffrey de Marisco and Áed’s rivals took hostages, raided Connacht and constructed castles at Rindoon and Athleague, strengthening Shannon frontier control. Warfare brought cattle theft, captivity and local killings. Famine, cold and sickness compounded insecurity, while crusading observances linked Ireland to Christendom.

In 1226, Connacht remained unstable after Cathal Crobderg Ua Conchobair’s death, as his son Áed faced dynastic rivals, neighbouring lords and changing English policy. Killings, attacks on houses, captivity and local feuds across Connacht, Breifne and Iar-Chonnacht exposed fractured authority. Henry III ordered Geoffrey de Marisco to demand Connacht’s surrender from Áed, advancing Richard de Burgh’s interests despite opposition among colonial magnates. Cathal Ua Raigillig destroyed Cill Mór castle, illustrating the vulnerability of frontier strongholds. Deaths of bishops, nobles and Cong’s learned erenagh also marked the year, while religious houses preserved learning, patronage and dynastic commemoration amid wider ongoing conflict.

In 1225, Connacht was devastated by a succession war after Cathal Crobderg Ó Conchobair’s death. Toirrdelbach, son of Ruaidrí Ó Conchobair, was inaugurated at Carnfree with support from Áed Ó Néill and Connacht allies, but Áed mac Cathail regained power through Anglo-Norman, Thomond and local assistance. Campaigns centred on cattle, territory and hostages, displacing communities and bringing plunder, killings, drowning, hunger and exposure. Alliances repeatedly shifted, while church and secular lands suffered alike. A second rising failed, forcing Ruaidrí’s sons back to Ulster. Fever, disrupted harvests and ploughing compounded destruction, leaving Áed restored but Connacht socially and economically shattered severely.

Cathal had combined authority with diplomacy towards Henry III, seeking security for Connacht and recognition of Áed. Meanwhile William Marshal suppressed Hugh de Lacy’s rebellion, retaking Trim Castle through campaigning supported by Anglo-Norman and Gaelic allies. Áed joined these wider struggles, attacking castles and resisting rivals backed by Áed Ua Néill. Church life included Cathal’s Cistercian burial, learned clerics, and the arrival of Dominicans. War, weather and livestock disease disrupted agriculture, exposing dependence on cattle, supplies and alliances.

In 1223 Ireland remained politically fragmented, with Henry III’s lordship concentrated in towns and lowlands while Gaelic rulers retained regional power. William Marshal’s Welsh campaign and Hugh de Lacy’s return heightened uncertainty in Ulster and Meath. In Connacht, local men captured William de Lacy’s built crannog. Clonmacnoise burned, destroying churches and valuables, though church construction continued at Tech Sinche. Episcopal deaths, resignations and elections altered ecclesiastical leadership, while Connacht lost clerical and political figures. Raiding, hostage-taking and violations of sanctuary exposed local conflict. A severe September wind damaged standing oats, underlining agricultural vulnerability.

In 1222, Ireland remained politically divided between Gaelic lordships and the Anglo-Norman lordship, whose authority was strongest in eastern and south-eastern towns and castles. Hugh de Lacy’s return exposed fragile royal control: Henry III restored some inherited lands but retained Ulster, while annals link de Lacy’s alliance with Áed Ó Néill to raids, Culrathain’s destruction and negotiated terms at Dundalk. An exceptional great wind damaged buildings, woods, churches and ships, disrupting rural, maritime and commercial life. Annals also record ecclesiastical deaths, elite benefaction and moral judgement. Farming, trade, kinship, warfare and religious institutions bound together a connected yet uneven society.

Ireland in 1220 comprised competing lordships, Gaelic kingdoms, ecclesiastical communities and growing towns rather than a unified polity. Walter de Lacy’s attempted castle at Áth Liag was abandoned after Cathal Crobderg Ua Conchobair intervened, demonstrating limits to frontier expansion. Connacht’s succession remained insecure as a rival claimant sought western maritime support. At Derry, the successor to St Columba’s office prompted disputes resolved through local consent and Armagh’s arbitration. Papal intervention, church consecration and episcopal death illustrate religious connections and instability. Annalistic dating differs for several events.
