Abstract
In 1290, Irish politics saw several local struggles for authority. Cairbre Ó Máelsechlainn, king of Meath, was treacherously killed by Mac Cochlain and the Delbhna amid overlapping Gaelic and colonial lordships. Domnall Ó Néill expelled Niall Ó Néill and seized Tír Eógain, while Toirdelbach Ó Domhnaill, supported by maternal kin and galloglasses, deposed his brother Áed in Tír Chonaill. William Mac Fheorais assumed effective possession of Tuam’s archbishopric, and Kilmacduagh’s bishop died. Edward I appointed William de Vesci justiciar; he arrived in Ireland, combining royal office with Kildare lordship. A Carmelite friary at Kildare was plausibly founded about this time.

In 1289, Ireland’s overlapping lordships were tested by warfare, alliance and royal intervention. Richard Tuite led Meath settlers and Connacht’s king Maghnus against Uí Máel Sechlainn, but was killed when their coalition lost at Crois-Shliabh. Fiachra Ó Flainn was murdered while seeking a marriage alliance with settlers, while Mac Muiris and Mac Feorais suffered defeat against Leinster princes, losing Meyler de Exeter, horses and spoils. John fitz Thomas FitzGerald secured Peter Bermingham’s lifetime military service. Archbishop John of Sandford, keeper of Ireland, campaigned in Laois, enforcing the king’s peace. Annalistic deaths also reveal active ecclesiastical and learned institutions amid instability.

In 1288 Magnus Ó Conchobair seized Connacht after defeating and capturing his brother Cathal at Bellaslishen, a strategic ford near Roscommon. His victory brought plundering, but winter attacks at Ros Mór wounded him and exposed continuing resistance. Recovering, he took hostages in Síl Muiredaig to enforce obedience. Richard de Burgh, Red Earl of Ulster and lord of Connacht, advanced to Roscommon but withdrew amid opposition, although sources dispute subsequent terms. Stephen de Fulbourn, archbishop of Tuam and justiciar, died, prompting William de Bermingham's election. Changes in church and chancery office reflected contested authority among Gaelic rulers, magnates and royal administration.

1287 in Ireland was marked by succession, local violence and deaths without island-wide upheaval. Thomas de Clare, lord of Thomond, died on 29 August, leaving his six-year-old heir Gilbert and placing lands under wardship. His death altered but did not end contested power around the Shannon; Toirrdelbach Ó Briain later raided Ormond and Limerick. In Connacht, Diarmait Midech Mac Diarmata and Gilla na nÉc Ó Mannacháin died alongside lesser rulers and clerics. Archdeacon Florint Ó Gibealláin was praised for learning. Máel Sechlainn Mag Oirechtaig was killed in revenge for broken loyalty. Misdated de Burgh campaigns belong to 1291, not 1287.

A year recorded through a single campaign The surviving Irish annals make 1286 look, at first sight, like a year dominated by one extraordinary movement of armed power. Their central notice is a mórshluaiged, or great hosting, led by the Earl of Ulster into Connacht. The earl was Richard de Burgh, later famous as the Red Earl: lord of Connacht through his inheritance and one of the greatest magnates in the English lordship of Ireland.

In 1285, records from Connacht and Bréifne depict contested local power rather than a national crisis. Magnus Ó Conchobair defeated Adam Cusack’s settler force at Ballysadare, killing many and capturing Colin Cusack, but Pilib Mac Gosdelb soon routed Magnus’s followers at Sliabh Gamh, with heavy losses among lesser levies. Ruaidrí Ó Gádra, king of Sliabh Lugha, was killed by Mac Feorais near Lough O’Gara. Simon Ó Ruairc, bishop of Bréifne, died, as did Alis, daughter of Cormac, and Enri Mac Gilla Finnein. Annals emphasise fluid alliances, strategic routes, hostage-taking, and precarious lordship, while warning against chronologically misplaced later annalistic entries.

In 1284, Irish politics was shaped by local conflict, succession and contested lordship rather than an island-wide crisis. In Thomond, Toirdelbach Ó Briain killed his rival Donnchad, strengthening his position and troubling Thomas de Clare’s Bunratty lordship. In Connacht, Simon d’Exeter’s death provoked raids, while losses suffered by Holy Trinity Island and Boyle Abbey were repaid; Fiachra Ó Flainn burned Dunmore. King Cathal mac Conchobair Ruaid demolished Kilcolman Castle, challenging fortified authority. Elphin saw rapid episcopal changes after two deaths. Killings of northern chiefs further demonstrate fragile regional power, where kinship, churches, compensation and strongholds shaped political control across Ireland.

In 1283, Áed Buidhe Ó Néill, king of Tír Eógain, was killed by rivals from Airgíalla and Breifne, destabilising northern politics and encouraging a contested succession. In Connacht, the wounding and death of Tadc Ó Conchobair illustrated dynastic rivalry and the political value of custody. Domnall Ruad Mac Carthaig of Desmond countered a plot with support from prominent Anglo-Irish lords, securing a negotiated settlement involving livestock. Dublin and Christ Church suffered a serious fire, exposing urban vulnerability. Together, these events reveal Ireland as a network of competing lordships, temporary alliances, ecclesiastical institutions, commerce, violence and negotiation across the whole island.

In 1282, Muirchertach Mac Murchada, king of Leinster, and his brother Art were murdered at Arklow on 21 July while travelling under safe conduct to meet Roger Bigod in England. Evidence links the killing to justiciar Stephen de Fulbourn’s frontier policy, exposing the insecurity of agreements between Gaelic rulers and royal government. Their deaths temporarily weakened Leinster unrest but did not end contested lordship. Annals also record Taichlech Ó Dubhda’s killing, Lasarfina Ó Conchobair’s death, chieftaincies changing hands, and prolonged winter snow. These events reveal Gaelic, Anglo-Irish and royal worlds, while annalistic dating cautions against assigning uncertain conflicts to 1282.

In 1281, Domhnall Óg Ó Domhnaill of Tír Conaill was defeated and killed at Disert-da-chrioch by Áed Buide Ó Néill’s forces, supported by the English of Ulster, devastating his wider political coalition. His son Áed succeeded him. Connacht saw fighting between the Barretts and Cusacks, while Tadhg Mac Diarmada of Moylurg died. In Thomond, rival Ó Briain factions accepted division and Thomas de Clare’s overlordship, enabling relative peace and Quin Castle’s completion. Richard de Burgh assumed Ulster and Connacht. Dublin strengthened administration under Stephen de Fulbourn, reopened its mint, and established one at Waterford, expanding royal revenue and fiscal capacity.

In 1280 Ireland saw conflicts exposing authority. In Thomond, Thomas de Clare’s attempt to establish a castle at Cuinche, near Quin, was devastated by a night attack led by Tairdelbach and Domnall Ó Briain; de Clare escaped to Bunratty, though Quin was completed later. In Connacht, Áed Muimhnech Ó Conchobair was killed during dynastic struggle, and Cathal Ó Conchobair gained kingship. Máel Sechlainn Ó Conchobair was ransomed for 400 cattle and 20 horses, illustrating livestock’s political value. Annals noted deaths of churchmen and Desmond barons. Together, these events reveal contested lordship, resilient Gaelic power, dynastic rivalry, and embedded religious institutions.

In 1279, Ireland’s fragmented political and religious worlds were marked by leadership changes, local violence and expanding lordly authority. Archbishop Tomaltach Ó Conchobair of Tuam died after two decades in office, while killings among Connacht kindreds exposed persistent dynastic rivalry. Robert of Ufford’s administration strengthened castles at Roscommon, Rindown and Athlone, increasing demands upon surrounding communities and anticipating monetary reform. In Thomond, Thomas de Clare pursued settlement and castle-building at Quin amid Ó Briain resistance and continued campaigning. Elsewhere, aristocratic penitential burial, monastic patronage, learned tradition and a Tipperary land lease demonstrate ecclesiastical, cultural and agricultural life alongside conflict daily.

In 1278, Thomas de Clare’s ambitious lordship of Thomond provoked sustained conflict. On 11 May, he executed the displaced king Brian Ruad Ó Briain at Bunratty, allegedly with assistance from Brian’s captains. Brian’s son Donnchad later defeated de Clare’s forces at Quin, where a church was burned and many died. Connacht suffered violent succession struggles: King Tadc Ó Conchobair was killed, followed by further dynastic murders and Áed Muimnech’s contested accession. Violent deaths also affected regional rulers. Bishop Thomas Ó Cuinn died, while Cashel’s archbishop visited England. These events revealed authority’s dependence on alliances, hostages, resources and force across Ireland.

In 1277, authority in Ireland was contested through dynastic rivalry, warfare, castles and law. In Thomond, Brian Ruad Ó Briain allied with Thomas de Clare, holder of Edward I’s grant to Thomond, against his nephew Toirrdelbach. Defeated, Brian sought refuge at Bunratty but was seized and executed on de Clare’s orders. In Connacht, Irish forces led by an Ó Conchobair and Domnall Ó Domnaill demolished Roscommon Castle, challenging royal control. Irish people reportedly offered 7,000 marks for English common law, seeking legal protections. The year also recorded ecclesiastical continuity and local raiding, illustrating Ireland’s plural, unstable political order throughout society.

In 1276, Ireland remained politically fragmented, with English lordship dependent on local power, finance and force. In Connacht, rivalry between Tadc Ó Conchobair and Áed Muimnech produced alliances, burnings, cattle raids, recoveries and deaths, affecting wider lordly communities. In Wicklow, Geoffrey de Geneville’s expedition was defeated at Glenmalure by Art Mac Murchada, Gearóid Ó Broin and allies, demonstrating mountain resistance to Dublin’s authority. Edward I replaced Geneville with Robert de Ufford, whose government sought firmer control through administration, military spending and fortifications at Rindoon and Athlone. Possible Irish interest in English common law also exposed law as a negotiable privilege.

In 1275, Ireland experienced regional conflict rather than a single national crisis. In Connacht, Tadc Ó Conchobair captured his brother Ruaidrí, raided Mac Diarmata territory, and lost his prisoner after Ruaidrí escaped with Conchobar Ó hAinlide, who was killed in pursuit. In Breifne, Art Ó Ruairc died at Granard during conflict involving Anglo-Norman forces. Annals also note killings among Gaelic kindreds, an Ulster victory over the Galls, and the deaths of bishops of Raphoe and Killala. Meanwhile, Edward I supported Justiciar Geoffrey de Geneville, ordering defence measures, an inquiry, and appointments. Sources caution against misdating events assigned differently in annals.

In 1274 Connacht suffered a rapid succession crisis after the death of Áed mac Fedlimid Ua Conchobair, a powerful king who had resisted Gaelic and Anglo-Norman opponents. Eogan mac Ruaidrí succeeded him but was killed by kin in Roscommon’s friars’ church after three months. Áed mac Cathail Dall then ruled for a fortnight before being killed at Grainsech Sruthra, leaving Tadc mac Toirrdelbaig king. Elsewhere, deaths and killings altered lordship in Brefne, Annaly and Dartry. Dublin’s forces were defeated at Glenmalure, while Edward I’s coronation and Thomas de Clare’s arrival linked Ireland to Plantagenet politics. The year revealed fragmented power.

In 1273, Irish authority remained fragmented among royal officials, settler magnates and Gaelic dynasties. Jordan d’Exeter’s raid in Corann provoked a failed Connacht pursuit, killing several members of ruling and learned families. Elsewhere, Conchobar Buidhe Ó Ruairc of Brefne and Eochaid Mac Mathghamhna of Oriel were killed, while expulsions altered power in western Connacht. Maurice FitzGerald’s expedition into Thomond obtained O’Brien hostages and submission, though not lasting conquest. Geoffrey de Geneville arrived as justiciar, strengthening royal administration without eliminating regional independence. Richard de Carew died, and a Barry charter granted Cahirduggan church to Ballybeg Priory, illustrating ecclesiastical patronage amid warfare.

In 1272, Áed Ó Conchobair, king of Connacht, intensified resistance to Anglo-Norman power by destroying Roscommon castle, burning Athlone and Meath towards Granard, breaking Athlone’s bridge, and deploying a flotilla on Lough Ree. Fighting also killed Henry Butler of Umhaill, while dynastic violence and deaths unsettled Connacht and Breifne. Justiciar James de Audley died amid disputed circumstances, weakening royal administration, though official links with England continued. Henry III’s death brought Edward I’s succession as lord of Ireland. Annals also record elite deaths and burials, while warfare devastated settlements, resources, travel and local security across western and central Ireland that year.

Walter de Burgh, earl of Ulster and lord of Connacht, died at Galway in July 1271, leaving his young heir Richard vulnerable during a minority. His death coincided with Áed mac Fedlimid Ó Conchobair’s destruction of castles at Templehouse, Sligo and Athleague, weakening de Burgh authority across Connacht. Killings in Connacht, Annaly, Oriel and the Breifne borderlands further revealed fragmented lordship and shifting local alliances. Annalistic notices also record religious deaths, penitence and burial, reflecting political and spiritual culture. Although Anglo-Norman power endured, 1271 reduced its capacity while Áed’s Gaelic kingship remained formidable, making the year a significant turning point.

In 1270, Áed Ó Conchobair defeated Walter de Burgh’s Connacht expedition at Áth an Chip after manoeuvres around the Shannon, failed negotiations and hostage-taking. Local forces harassed the invaders, broke their vanguard and rear guard, and inflicted notable losses. Áed subsequently attacked castles, towns and settlements, including Roscommon, although conflict and reprisals continued across Connacht, Sligo, Corann and Thomond. The campaign demonstrated the strength of Gaelic kingship against Anglo-Irish magnates without ending de Burgh’s influence. Ireland also suffered widespread hunger and destitution. The year saw Archbishop Máel Pátraic Ó Scanaill’s death and Tanaide Mór Ó Maelchonaire’s succession as Connacht’s ollamh.

In 1269 Robert de Ufford, the English crown’s justiciar, began Roscommon Castle while Áed Ó Conchobair, king of Connacht, was ill, exploiting a temporary weakness to establish a durable royal foothold. The project disrupted local people and intensified Anglo-Irish pressure within Ó Conchobair territory, although it did not signify Connacht’s conquest. Sligo Castle’s rebuilding by Mac Muiris Mac Gerailt similarly demonstrated contested frontier control. Religious life featured Imar Ó Birn’s entry into Roscommon’s Dominican priory and aristocratic patronage. Annals also noted killings, the death of musician Áed Ó Finn, and uncertain reports of an earthquake and weather, requiring cautious chronology.

In 1268, Áed Ó Conchobair of Connacht defeated an army termed the Galls of Ireland at the Faes after answering a challenge at Athlone, strengthening Gaelic resistance to lordship expansion. The year also brought severe famine across Ireland, compounding warfare and pressures. In Thomond, King Conchobar Ó Briain, his family and followers were killed amid dynastic conflict, followed by reprisals and mutilation. Other rulers died or were killed in struggles. Ecclesiastical succession continued at Armagh, Clogher and Annadown, while the death of poet-host Aengus Ó Dálaigh reflected cultural life. Sea travel, northern captivity and escape show a fragmented, connected society.

In 1266, Connacht experienced conflict among Gaelic rulers, settler communities and Walter de Burgh’s lordship. Tiaquin Castle was demolished and Conmaicne ravaged, while townships, castles and grain stores were burned. Áed Ó Conchobair, king of Connacht, pursued rivals and projected authority into Bréifne, deposing Art Ó Ruairc, installing Conchobar Buide and taking hostages. His regime also used blinding as political punishment. Raids, killings and a failed Burke hosting demonstrated an unsettled balance of power. Despite warfare, monasteries, dioceses and learned families remained active, recording deaths, appointments and consecrations.

On 18 June 1264, an assembly at Castledermot became the earliest securely documented Irish gathering to call itself a parliament. Chaired by the justiciar Richard de la Rochelle, it investigated Dublin archbishops’ claimed criminal jurisdiction against Prince Edward’s rights, illustrating contested authority rather than representation. Meanwhile Walter de Burgh’s war with the FitzGeralds devastated Connacht and exposed weakness in royal administration. Anglo-Irish leaders negotiated peace with Fedlimid Ó Conchobair at Athlone, acknowledging Gaelic power. In Armagh, Archbishop Máel Pátraic Ó Scannail built defences and welcomed Franciscans.
