Tairdelbach’s Divided Ireland
Archived: 26 September 2026
In 1135, Ireland remained politically fragmented despite Toirdelbach Ua Conchobair’s strong, contested overlordship. Murchad Ua Máelshechlainn asserted Mide’s strategic river power by receiving hostages on the Shannon. Connacht endured dynastic killings, battles, raids and the destruction of Roscommon, while northern Uí Néill rivals, Munster factions and smaller kingdoms pursued warfare and shifting alliances. Malachy strengthened his disputed authority at Armagh by acquiring the Bachall Ísu, advancing church reform. Deaths of leading bishops and clerics, notably at Lismore, marked generational change. Fires damaged ecclesiastical centres, lightning struck towers, and plentiful mast harvest supported food supplies amid rural, maritime and market-based society.
