Dál Riada
Dalriada, Dál Riata
An ancient Hiberno-Scottish kingdom on the west coast of Scotland, which today covers Argyllshire, although it also included a small region in the north of Ireland.
It was founded by a group of emigrants from the kingdom of Dál Naraidi, and it is the alleged homeland of the Scottish people. The King of the newly founded domain, Aedán mac Grabáin, maintained close links with the parent kingdom and was a close ally of Fiachna Lurgan.
The son of Aedán mac Gabráin, known as Arthur of Dál Riada, has been suggested as the historical origin of King Arthur.
