Amlaíb’s Two Royal Killings
Archived: 26 October 2026
Abstract
In 977, Amlaíb Cuarán, Scandinavian-Gaelic ruler of Dublin, killed Muirchertach son of Domnall ua Néill and Congalach son of Domnall, both designated royal heirs of Ireland. Their deaths weakened Domnall, king of Tara, amid contested Uí Néill succession, illustrating Dublin’s influence within intertwined Irish and Viking dynasties. Domnall also killed Gilla Coluim ua Canannáin, lord of Cenél Conaill. Annals record Conaing, successor of Moedóc, dying, while Chronicon Scotorum chronologically associates Domnall’s plundering of Adomnán’s shrine with 977. Irish sources also noted a Scottish royal killing, reflecting Irish Sea connections. Misdated records exclude Leinster and Kildare events from this calendar year.
