In 1455 Henry O’Neill was inaugurated at Tullyhogue as king over Ulster, backed by allied lords and Armagh’s ecclesiastical leader, although his father remained alive and dynastic conflict persisted. Elsewhere, Philip Maguire’s forces raided east Breifne, burning settlements, killing rivals and capturing a crannog, demonstrating mobile lordly warfare. Annals also recorded deaths among ruling, clerical and learned families, revealing networks of status, hospitality and service. At Navan, Abbot John Bole granted a Pentecost indulgence supporting religious observance and monastic repair. In Connacht, a lord was killed by his own men. These events illustrate Ireland’s multiple, localised and precarious political worlds.

In 1454, Ireland’s fragmented political order was illustrated by conflict, succession and cultural exchange. At Inis Castle in Tír Chonaill, Domhnall O’Donnell killed rival Ruaidhrí O’Donnell with a stone during a siege, securing the lordship temporarily. Annals also record deaths and kin violence among the O’Reillys, Maguires and O’Molloys, alongside contested local successions and cattle raids. Sir Edward FitzEustace’s death led to Thomas fitz Maurice FitzGerald’s election as justiciar in Dublin. Notices commemorate elite women and a notable Fermanagh sermon. Meanwhile, Edmund MacRichard Butler’s manuscript, copied by Gaelic scribes during campaigning, vividly demonstrates interconnected Anglo-Irish patronage, learning, warfare and mobility.

In 1453, Irish annals record regional struggles rather than a national crisis. At Ardglass, a Dublin fleet pursuing Welsh raiders who had seized the archbishop defeated Henry Mac Néill Buidhe’s Clandeboye force, aided by the Savages; leading Ulster men died and Henry was captured. In Oriel, Hugh Roe MacMahon died and was succeeded by Felim MacMahon, while Donnchadh MacCarthy Reagh’s death brought Diarmaid an Dúna to power in Carbery. Killings, deaths and disputed lordships in Connacht, Bréifne and Tirerrill revealed political dependence on kin, followers, castles and church patronage. The record depicts maritime, localised and interconnected late-medieval society in Ireland.

In 1452, Ireland was governed through competing lordships, kinship, warfare and negotiation. Neachtan Ó Domhnaill’s assassination by nephews destabilised Tír Chonaill, enabling Énrí Ó Néill to broker a settlement while gaining territory and tribute. Marriage alliances drew James Butler, fourth earl of Ormond, north to compel Énrí’s reconciliation with his first wife. Fighting in the Fews ended with compensation and peace. Ormond’s rapid circuit across the midlands and north-east secured submissions, payments and prisoners, but he died at Ardee in August. His death weakened settlements. Annals also noted the Liffey’s recession, raids on Teagh-Munna, plague, and deaths among learned families.

For Ireland, 1451 is not a year dominated by one island-wide campaign or governmental act. Its surviving record is instead a set of sharply local episodes: the death of a renowned midland patron, a fire in a Franciscan friary at Cavan, a return from Rome, murders and hostage agreements, and the building of a castle in Connacht. Read together, they show an Ireland of overlapping lordships rather than a single political community: Gaelic rulers, Anglo-Irish families, religious houses and learned networks all exercised authority in particular places.The evidence has limits.

In 1450 Thomas Óg Mág Uidhir, lord of Fermanagh, departed for Rome’s jubilee, demonstrating Gaelic lordship’s international religious connections and dependence on learned patronage. During his absence, Donnchadh Dunchadhach Maguire murdered Cathal Maguire, seized his wealth, and sought wider power; after negotiation, Edmond Maguire captured and mutilated him. Annals also record deaths of Clogher’s Maguire bishop, pilgrims and physician Tadhg Ó Cáiside, illustrating ecclesiastical and hereditary service networks. Elsewhere, Ó Néill raids, alliances and killings, and an Ó Raghallaigh settlement reshaped northern politics. Richard, duke of York, left Ireland in September, appointing Ormond deputy, thereby highlighting Ireland’s multiple political centres.

In 1449 Richard, duke of York, arrived in Ireland as Henry VI’s lieutenant, combining royal office with extensive Irish lordships. At Drogheda, he concluded an agreement with Énrí Ó Néill, backed by Eóghan Ó Néill, exchanging military support for protection. York received earls, negotiated hostages from Meath and demonstrated government through personal alliances rather than conquest. Elsewhere, disputed successions destabilised Breifne, while warfare involved Ó Néills, MacQuillans, Scottish connections and Cenél Conaill. Annals also record religious renunciation, dynastic deaths and learned families. The year reveals a plural political landscape, where English administration and Gaelic rulers formed shifting, pragmatic coalitions locally.

Records for 1448 depict Ireland as a patchwork of lordships, religious houses and learned networks rather than a single national story. A severe plague in Meath caused deaths among laymen, a ruling family and friars. Killings in Leinster and Connacht, alongside changes in regional lordships, reveal persistent rivalry within and between political communities. Bishops, abbots and aristocrats died, while a couple drowned on an Ulster waterway, underlining travel’s hazards. Donal Mac Cárthaigh Mór supported the Observant Franciscan foundation at Muckross. The deaths of poets Tadhg Óg Ó hUiginn and Diarmait Ó Dálaigh highlighted institutions of education, hospitality, patronage and commemoration.

In 1447, Ireland’s divided political worlds were linked by conflict, administration, religion and epidemic disease. Domnall Ballach Maguire was killed amid Fermanagh succession rivalry, while Hugh Maguire and Breifne constable Cormac Mac Cába also died. At Trim, Lord Lieutenant John Talbot imprisoned Feidhlimidh Ua Raghallaigh, who later died of plague and was buried in the Franciscan friary. Talbot’s parliament regulated trade, officials, coinage and English dress. Plague caused heavy mortality across several provinces, affecting clergy, lords, lawyers and scholars. Meanwhile, Thomas Óg Maguire rebuilt Aghalurcher church, and an Ó Mórdha lord founded a Franciscan burial house in Laoighis for descendants.

In 1446, Neachtan Ó Domhnaill led an army from Tír Chonaill through Breifne and Connacht, where Mac William of Mayo received and escorted him at Dunamon, demonstrating interlordship alliances and negotiated military movement. Connacht suffered Ó Conchobhair dynastic violence, while Clanricarde intervened in Thomond and mediated a Mac Donnchada partition. Ó Conchobhair Fáilghe raided Meath, exposing the English lordship’s vulnerable frontier. Successions, feuds and retaliatory killings affected Ulster and Leinster, including murder within Fenagh church. Annals also commemorated poets, clerics and devotees. Together, these records depict Ireland as interconnected by kinship, routes and ecclesiastical institutions, but fractured among competing lordships.

In 1445, Ireland’s fragmented political order was exposed by the burning of Sligo, attacked by O’Donnell, Maguire and discontented Ó Conchobhair kinsmen opposing Toirdhealbhach Carrach. Dynastic disputes also destabilised Annaly and West Breifne, where contested lordships prompted warfare, division or rival proclamations. Other annals record killings during raiding and travel, revealing pervasive local feud. English authority remained limited: John Talbot’s appointment as lieutenant did not bring immediate control, while Gaelic lords used written diplomacy and ecclesiastical seals. Irish nobles travelled to Santiago, clerics were commemorated, and Athenry’s Dominican friary housed thirty members, demonstrating religious networks amid conflict and political negotiation.

In 1444, Aodh Buidhe O’Neill of Clandeboye died from wounds received raiding Iveagh, prompting Eóghan O’Neill of Tír Eógain to intervene. Clandeboye leaders, allied with the MacQuillans, ambushed and defeated him in Dufferin, taking hostages including his son. Eóghan also compelled Dundalk to pay money and wine, while English government met at Drogheda with limited reach. Thomond suffered a violent Ó Briain succession rupture, including Mathgamain’s blinding and Toirdelbach’s seizure of power. Rome appointed Cormac Mác Shamhradháin bishop of Ardagh, while Trim’s Marian miracle cult, charity, deaths, warfare, and learned patronage reflected Ireland’s interconnected yet fragmented political and religious world.

In 1443, Muirchertach Ó Cellaigh briefly captured Athlone Castle, a key Shannon crossing, before James Dillon and William Boy Dillon recovered it; William Boy was killed, while Muirchertach received safe conduct. The episode illustrated contested authority and negotiated frontier politics. Annals also record deaths, feuds, raids, restitution and killings among Irish lordships, notably in Oriel, Ulster, Connacht, Ossory and the midlands. Aengus Mac Gilla-Fhinnein, abbot of Lisgoole, died on 17 September. Legal scholars Gilla na Naem Mac Aodhagáin and Hugh Mac Aodhagáin were commemorated. Differing annalistic dates complicate events in Thomond, showing Ireland's connected institutions amid persistent conflict and rivalry.

In 1442, James Butler, earl of Ormond, resumed the Irish lieutenancy, governing through fragile alliances rather than centralised power. In the north-west, Énrí and Eóghan Ó Néill secured assistance from the English settlement and compelled Neachtain Ó Domhnaill to cede Castlefin, Cenél Moen and Inis Eógain’s tribute. Other struggles involved Enniskillen, Oriel, Ulster raiding and Wicklow warfare. After Muircheartach Caomhánach’s killing, his father won prisoners and compensation from Wexford. Obituaries recorded lords and clergy, while Ormond rental accounts reveal farming, rents and seigneurial justice. Together, the sources portray a connected, contested Ireland shaped by castles, kinship, tribute, negotiation and authority.

Annals for 1441 chiefly record deaths that exposed the importance of Ireland’s learned, ecclesiastical and lordly networks. Mailin mac Tanaide Ó Maolconaire, eminent historian and ollamh of Síol Muireadaigh, died in mid-February and was honourably buried at Cluain Coirpthe; other scholars, poets and churchmen also died. Conchobar Mac Donnchada, lord of Tír Oilella and patron of poets, was among them. Regional conflict continued through Mag Samradhain feuding, Maguire raids in Fermanagh, and Mac William Uachtarach’s capture of Ó Madden’s Shannon castle. Ecclesiastical offices linked kin, land and learning, while English administration remained significant chiefly in eastern Ireland during this year.

Annals for 1440 depict regional political and social change rather than an island-wide event. Walter Burke, Mac William Íochtar of Lower Connacht, died of plague in early September and was promptly succeeded by his brother Edmund, illustrating Gaelicised kin-based succession. Neachtan O’Donnell and Owen O’Neill made peace, temporarily easing northern conflict. In Fermanagh, deaths and killings among Maguire kin revealed interconnected lordly households, while Matthew Mac Craith’s replacement as coarb of St Dabeoc showed hereditary ecclesiastical authority. The deaths of historian Duibhgenn Ua Duibhgennáin and lawyer Domnall Ua Breislen underscored learned orders’ political importance. Sources remain fragmentary and cautiously dated.

In 1439, Irish politics were shaped by local struggles over captives, castles, succession and recognition. Domhnall Ballach Maguire seized Tomás Óg Maguire at Enniskillen, securing his release only through hostages and control of the castle. Niall Garbh Ó Domhnaill died in English captivity, enabling Neachtan’s succession in Tír Chonaill, although sources dispute where he died. Cathal Ó Conchobair’s death triggered competing claims to Connacht’s kingship and warfare. Dublin suffered plague, while lordship changed through Donnchadh Dubh Ó hEadhra’s religious profession. A reported English deputy’s capture further illustrates fragmented authority, negotiated power and connections across Ireland and the Irish Sea alike.

In 1438 Ireland remained divided among Gaelic lordships, Anglo-Irish communities and ecclesiastical jurisdictions, with power shaped by kinship, warfare and office. Archbishop Thomas Crawley died in England returning from the Council of Basel, linking Dublin to Church conflict, while Lionel, Lord Welles, became royal lieutenant. O’Conor Faly fought Meath’s English yet made peace with his brother. Captures, killings and depositions affected Maguires, O’Dowdas, O’Donnells and O’Briens. Deaths of bishops, clerics and heirs from disease disrupted institutions. Prominent jurists, historians and poets also died, demonstrating learned patronage’s continuing public importance. Annals record these crises unevenly rather than a unified national narrative.

Gormlaith Ó Duibgeannáin, wife of Brian Mac Aodhagáin, died as an anchorite at Loch Key, linking learned kinship and religious life. Ulster notices named three deaths, while a cautiously dated peace between Niall Garbh Ó Domhnaill and his brother Neachtan reflected strained northern lordship. Farming, trade and uneven royal authority shaped everyday life. News of James I of Scotland’s assassination demonstrated Ireland’s continuing Irish Sea connections across a politically fragmented island.

A Winter Made PassableFor Ireland, 1435 opened in a landscape temporarily remade by cold. The annals call it an exceptional frost: lakes and rivers were hard enough to be crossed on solid ice. The Annals of Ulster add an unusually vivid detail from Fermanagh. When Eóghan Ó Néill entered the region with an army, the people of Fir Manach moved cattle, horses carrying loads and other portable goods westward across Lough Erne—not in boats, but over the frozen lake. This was not merely a picturesque curiosity. It changed the practical geography of a frontier lordship. Water that normally protected communities,

In 1434, Eóghan Ó Néill of Tír Eóghain and Niall Garbh Ó Domhnaill of Tír Chonaill, recently rivals, led a broad Ulster coalition into the English lordship. They exacted tribute at Sradbaile, burned Sliabh Breagh and Oriel, and attacked Nobber Castle. Thomas Stanley’s mounted response allowed Ó Néill’s sons to withdraw safely but trapped Ó Domhnaill’s separated party seeking cattle. His heir Toirdhealbhach and other leaders died, while Niall Garbh was captured, enabling his brother Neachtan to rule. Annals also recorded deaths among churchmen and learned families.

In 1433, regional conflict, diplomacy, famine and patronage shaped Ireland. Eóin Ó Néill, aided by Mac Domhnaill’s Scottish fleet, campaigned against Niall Garbh Ó Domhnaill and MacQuillan in Dufferin, devastating creaghts and burning Ardglass. Negotiations by Niall Garbh’s wife and subordinate rulers halted a proposed attack, while subsequent travel produced peace at Caol Uisce. In Breifne, Mag Raghnaill factional warfare involved paid soldiers. Severe summer famine accompanied notable hospitality by Mag Uidhir and Margaret Ó Cearbhaill. Pope Eugenius IV licensed Franciscan Regular Observance at Quin, reinforcing Mac Conmara patronage and linking local lordship to wider ecclesiastical reform currents across Europe.

The best-documented Irish event of 1429 was a major defeat at Achadh Cille Móire, now generally identified with Aghakilmore in County Cavan. It was not a battle between two neatly bounded nations. Rather, it grew from the shifting alliances, rival branches and armed followings that shaped lordship in the Breifne borderlands. The annals place it firmly in this year, while their differing emphases also reveal why a single encounter could matter far beyond the field on which it was fought.
