Abstract
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 1437, Ireland’s annals recorded regional transitions rather than a national event. Seoan Mac Peorais, Archbishop of Tuam, died, opening a contested ecclesiastical vacancy resolved neither quickly nor simply. 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.

In 1436, Ó Conchobhair Fáilghe launched raids against the English lordship, reportedly avenging the captivity of an Ó Domhnaill kinsman. English settlers of Meath, Ó Fearghail allies and the Prior of Kilmainham defeated him, though conflict continued. In Ulster, Niall Ó Néill was killed in a night attack, while Eóghan Ó Néill secured the crannóg of Loch Laoghaire before raiding Tírhugh. Annals also record local deaths and feuds. The deaths of jurist Gilla-Íosa Mac Aodhagáin and historian Geanann Mac Cruitín, alongside a 1436 Dindshenchas manuscript, attest to enduring learned culture amid fragmented, interconnected warfare and lordship across Ireland's political landscape.

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. Late in the year, severe frost froze major lakes, disrupting life and travel.

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.

Abstract
In 1431, Ireland experienced raids, reprisals, dynastic conflict and institutional losses. Sir Thomas Stanley's delayed arrival as royal lieutenant left the English lordship constrained around Dublin, though chancery business continued. After John Maguire was killed in Tullyhaw, Tomás Óg Maguire ravaged the district and burned Ballymagauran. O'Neill, Maguire and O'Reilly devastated MacQuillan territory, while hostage negotiations and O'Donnell rivalries reshaped Ulster. Gaelic and English forces conducted reciprocal raids in Breifne and Leinster. Deaths of bishops, clerics, poets and nobles underscored the fragility of lordship. Warfare damaged crops and homes, yet religious, learned and administrative institutions endured amid mobile local power.

Abstract
In 1430, Irish political life was marked by warfare, negotiation and succession rather than an island-wide event. Tomás Mág Uidhir died on 13 November after thirty-six years ruling Fermanagh, and his son Tomás Óg succeeded with publicly affirmed support. Eóghan O’Neill raided Oriel and Meath, securing tribute, submissions and a hostage without permanently conquering these territories. In Cork, Kilbrittain castle changed hands amid MacCarthy and Desmond conflict. Raids and rival claims affected Connacht and Breifne, where sanctuary and éraic enabled settlement. Deaths of clerics and legal scholars underline ecclesiastical and learned institutions’ roles in authority, hospitality, memory and social order.
