Historical Trajectory
Phase I: Rise
Dunoding traces its origin to around 460 AD, when Cunedda Wledig's son Dunod is said to have driven Irish settlers from the north-west Welsh coastal region. The sub-kingdom was established as a subordinate realm within Gwynedd, bearing the name of its founding figure. It occupied the territory that would later be divided into the cantrefi of Eifionydd and Ardudwy along the south-western fringes of Gwynedd.
Phase II: Zenith
During its existence as a recognised sub-kingdom, Dunoding maintained its own ruling line descended from Dunod. As part of Gwynedd, it occupied a strategically positioned coastal territory in north-west Wales. The sub-kingdom persisted for several centuries under the House of Dunod, functioning as an integral subordinate unit within the broader political structure of early medieval Gwynedd.
Phase III: Decline
The sub-kingdom came to an end around 925 AD when the ruling line of the House of Dunod expired. Following this, Dunoding was divided into the cantrefi of Eifionydd and Ardudwy and fully absorbed into Gwynedd. After Gwynedd's defeat and annexation to England in 1283, these territories became parts of Caernarfonshire and Merionethshire, and are now within the modern county of Gwynedd.
