Abstract
In 1110, Ireland remained divided among local and provincial rulers, dominated by Muirchertach Ua Briain of Munster and Domnall Ua Lochlainn of Ailech. Ua Lochlainn raided Connacht, taking many cattle and captives, while its young king, Tairdelbach Ua Conchobair, won at Ros but suffered defeat at Mag Brengair. Elsewhere, the Ulaid plundered Mucnám and regional kings were killed. Dynastic deaths affected Munster and northern alliances. Cellach of Armagh visited Mide, collecting dues and advancing church reform. Learned churchmen also died. Annals chiefly preserve elite violence and religion, while rural farming, trade, craftsmanship and learning sustained wider society throughout the year.

Abstract
In 1084, Ireland remained a patchwork of kingdoms, where Tairdelbach Ua Briain of Munster maintained overlordship through alliances and warfare while northern rivals strengthened. Raids devastated Ulaid, Munster and church sites, reflecting cattle's economic and political importance. Donnchad Ua Ruairc led a multi-provincial force into Leinster but was defeated and killed by Muirchertach Ua Briain's coalition at Móin Cruinneoige, enhancing Ua Briain power. Churches at Glendalough and elsewhere suffered, though Rossory gained a foundation. Dublin's bishop Gilla Pátraic drowned, highlighting overseas connections. Reports of pestilence, urban commerce and rural disruption reveal a society shaped by conflict, religion and shifting authority.
