Dúnadach at Umall
Archived: 29 October 2026
Abstract
In 813, Dúnadach, king of Umall in modern County Mayo, and Coscrach son of Flannabra were killed when heathen seaborne raiders defeated local forces. The annals provide no details of the battle, loot, or lasting conquest, but place it amid western coastal fighting following Irish resistance in 812. The year also saw Daire’s law promulgated among the Uí Néill, probably protecting cattle, a vital economic resource. Obituaries for rulers and church leaders illustrate dispersed political and ecclesiastical authority. These events depict Ireland as a landscape of vulnerable coasts, regional kingdoms, valuable herds and religious communities, rather than a unified state.
