Kings, Clergy and Cattle
Archived: 26 September 2026
In 1150 Ireland remained divided among competing provincial and lesser kings, with Muirchertach Mac Lochlainn strengthening his high-kingship through hostages, alliances and the partition of Mide. Tairdelbach Ua Conchobair retained Connacht, while Tairdelbach Ua Briain raided Mide, gained Dublin’s submission and campaigned in Leinster. Warfare, cattle raiding, killings and dynastic punishments accompanied short-lived negotiated peace. Clergy at Armagh and Derry legitimised rulers, mediated settlements and collected substantial livestock tribute. Church reform advanced alongside older monastic networks; Bishop Muiredach Ua Dubthaig died. Fires damaged religious settlements. Cattle, horses and urban trade underpinned power, exposing warfare’s burden on ordinary households throughout Ireland.
