Corcu Duibne

The Corcu Duibne, which means "seed or tribe of Duibhne" (an Irish personal name), was a notable kingdom in prehistoric and medieval County Kerry, Ireland which included the Dingle Peninsula, the Iveragh Peninsula and connecting lands. The tribe belonged to the Érainn and claimed descent from the legendary Conaire Mór, possibly making them distant cousins of such far off kingdoms as Dál Riata in Ulster and Scotland, as well as the closer Múscraige and Corcu Baiscind. All the tribes belonged to the Síl Conairi of legend and ultimately traced their descent from the Clanna Dedad.

The ruling septs of the Corcu Duibne were O'Shea and O'Falvey, and possibly O'Connell.

Noted creators of ogham inscriptions, with over one third of all Irish inscriptions found in their region, the existence of the Corcu Duibne is attested as early as the 5th century. These tell us they claimed descent from a female ancestor DOVINIA.

The Iron Age mountaintop fortress Caherconree, preserving the name of the legendary Cú Roí, a cousin of Conaire Mór, is found on the Dingle Peninsula, the name of which in Modern Irish is Corca Dhuibhne.

Relations between the Corcu Duibne and the nearby Eóganacht Locha Léin are poorly understood, but it appears they spent at least some period of time under the nominal overlordship of the latter in the powerful, but relatively short-lived Kingdom of Iarmuman. Rule from distant overkingdom of Eóganacht Chaisil is not apparent and so it is likely that the Corcu Duibne kingdom had an independent, if remote, existence in the first millennium.
