Abstract
In 829, as dated by the Annals of Ulster despite its U830 heading, Feidlimid mac Crimthainn, king of Munster, projected power into the midlands and Connacht. He burned Foire, probably Fore in Westmeath, and inflicted a major defeat on the southern Uí Briúin, though details remain unknown. Munstermen also killed Folloman, brother of Conchobor mac Donnchada, king of Tara, intensifying their rivalry. Deaths of abbots, bishops and local kings underline the interdependence of ecclesiastical institutions, dynasties and regional politics. No Viking attack is recorded that year; Irish warfare itself threatened settlements and churches. The year showed expansionist pressure, without resolution.

Abstract
In 828, as calibrated in the Annals of Ulster rather than the displaced Viking material assigned to 827, Ireland’s record combines deaths, violence and religious travel. Muiredach of Leinster and several lesser kings died, alongside leading churchmen and an ecclesiastical steward, illustrating layered political and institutional authority. Conaing was treacherously killed, while Mide defeated Connacht in an otherwise unexplained battle. Diarmait, abbot of Iona, carried Colum Cille’s relics to Scotland, demonstrating maritime links within the Columban world, although no motive is recorded. The sparse evidence depicts a fragmented yet connected society shaped by rulership, warfare, churches, economy and sea routes.

Abstract
In 827, Irish annals recorded conflict, church politics, Viking raids and royal diplomacy across a divided island. Niall Caille of Cenél nÉogain defeated forces of Ulaid and Airgialla at Leth Cam near Armagh, strengthening his influence and supporting Éogan Mainistrech’s ecclesiastical position. Church leaders also died at Tallaght, Fir Rois and Cell Achaid. Viking raiders burned Lusk, ravaged eastern districts and defeated a Leinster encampment, killing Conall of the Fortuatha. Violence disrupted fairs at Tailtiu and Colmán. Finally, Munster’s Feidlimid and Tara’s Conchobor held a royal conference at Birr, acknowledging competing powers amid instability within Ireland’s political and religious life.

Abstract
In 826, as conventionally dated despite annalistic discrepancy, Feidlimid mac Crimthainn, king of Munster, led an army into the midlands and burned Delbna Bethra, threatening Mide and estates linked to Clonmacnoise. His campaign challenged Conchobar mac Donnchada’s authority at Tara amid rivalry later followed by negotiations at Birr. Deaths of kings in Brega and Mide, and the deceitful killing and wounding of rulers in Tethba, exposed fractured local lordship. Ecclesiastical leaders died at Armagh, Clonard and Clonfert. A plague warning caused widespread fear, while Daire’s law was renewed in Connacht. No securely dated Viking raid is recorded in principal annals.
