The early medieval history of Ireland, often called 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 notably includes the Hiberno-Scottish mission of Christianized Ireland to pagan Great Britain and Europe.

The Medieval Period or Middle Ages occurred after the Golden Age Period in Ireland. People were already coming from all over Europe to study in Ireland’s monasteries, to trade and even settle.
