Abstract
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.

Abstract
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 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 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.

Abstract
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 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.

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.

Abstract
In 1246, newly built Sligo Castle became a focus of conflict between Maurice FitzGerald's expanding Anglo-Irish power and Máel Sechlainn Ó Domhnaill of Tír Chonaill. After attackers burned Sligo's enclosure but failed to seize the castle on 1 November, its garrison hanged two hostages, Ó Domhnaill's foster-father and foster-brother. FitzGerald also sought to reshape northern politics through Cormac Ó Conchobair and hostage-taking. Elsewhere during that turbulent year, John Fitz Geoffrey became justiciar; Connacht dynastic prisoners escaped, were recaptured, or were killed; bishops changed at Elphin and Armagh; Drumlane burned; Oriel suffered violence; and a stranded whale enriched coastal Sligo communities.

Abstract
In 1247, warfare across north-western Ireland and Connacht exposed fragile power among Gaelic, Anglo-Irish and maritime allies. Maurice FitzGerald’s force outmanoeuvred Tír Conaill’s defenders at Ballyshannon, killing Máel Sechlainn Ó Domhnaill and installing a provisional ruler, though losses followed during withdrawal. In Connacht, Toirrdelbach Ó Conchobair and allies captured strongholds, burned Galway and other settlements, while retaliatory raids devastated communities. Waterways, fords, crannogs and castles shaped campaigning, and sea travel brought both opportunity and disaster. Churchmen mediated evacuations and maintained wider connections. Meanwhile, partition of the Marshal inheritance reshaped Leinster’s lordship. The year ended without lasting political settlement or conquest.

Abstract
In 1248, military and political struggle linked northern and western Ireland across contested regions. Justiciar John FitzGeoffrey compelled Cenél nEógain to give hostages, then built a bridge over the Bann and a castle near Coleraine, strengthening royal leverage without securing conquest. Maurice FitzGerald intervened in Tír Conaill, backing Gofraid Ó Domnaill, whose rival was later killed. In Connacht, revolts, raids, cattle seizures, island warfare and a reverse in Connemara exposed limits to colonial power. Meanwhile, Fedlimid Ó Conchobair endowed Kilmore’s Augustinians, Armagh’s primate returned from Rome, and Henry III addressed baronial liberties, demonstrating intertwined warfare, lordship, church patronage and administration.
