Dál Riata (also Dalriada or Dalriata) was a kingdom on the western coast of Scotland.. Beginning in the early 5th century Dál Riata covered the area of what is now Argyll and Bute and Lochaber in Scotland. They came from the area of County Antrim in Northern Ireland where they were called 'Scots'. Other groups from Ireland followed. These groups also established themselves on the west coast as far south as Cornwall. The colony from Irish Dál Riata were known as the "Scotti" to the Romans. It was this group that later gave their name to Scotland.
