History of Ireland (400–795)

The early medieval history of Ireland, often referred to as Early Christian Ireland, spans the 5th to 8th centuries, from the gradual emergence out of the protohistoric period (Ogham inscriptions in Primitive Irish, mentions in Greco-Roman ethnography) to the beginning of the Viking Age. The period includes the Hiberno-Scottish mission of Christianised Ireland to regions of pagan Great Britain and the spread of Irish cultural influence to Continental Europe.
