Iverni

100 CE – 200 CE (approx.)

People of south-west Ireland named by Ptolemy, whose name is linked to the Érainn and to Ériu, the Irish name for Ireland itself.

Origins

Ptolemy's Geography of about 150 places the Iverni in the south-west of Ireland, around modern Cork, with a town called Ivernis and a river Iernus nearby. Their name is related to Ivernia or Hibernia, the classical name for the island, and to the Érainn, a population group prominent in the early genealogies of Munster.

Rule and society

Classical sources record nothing of their rulers or customs. Early Irish tradition remembers the Érainn as an ancient people of Munster, ancestors of groups such as the Corcu Loigde and the Corcu Duibne, who were powerful before the rise of the Eóganachta. The region has many ogham stones, the earliest Irish writing.

Decline and legacy

By the early medieval period the Érainn had been eclipsed by the Eóganachta, who built the Kingdom of Munster around Cashel. Érainn descendants such as the Corcu Loigde survived as subordinate kingdoms in west Cork.

Few sources survive for this state; details are uncertain.
