Dunoding was an early sub-kingdom within the
Kingdom of Gwynedd in north-west
Wales which existed between the 5th and 10th centuries. According to tradition, it was named after Dunod, a son of the founding father of Gwynedd -
Cunedda Wledig - who drove the
Irish settlers from the area in c.460. The territory existed as a subordinate realm within Gwynedd until the line of rulers descended from Dunod expired in c.925. Following the end of the House of Dunod it was split into the
cantrefi of
Eifionydd and
Ardudwy and fully incorporated into Gwynedd. After the defeat of the kingdom of Gwynedd in 1283 and its annexation to
England the two cantrefi became parts of the counties of
Caernarfonshire and
Meirionnydd respectively. It is now part of the modern county of
Gwynedd within a devolved
Wales.
