Kenneth MacAlpin or Kenneth I was King of Dál Riada (841–850), and King of the Picts (843–858) of likely Gaelic origin. He inherited the throne of Dál Riada from his father Alpín mac Echdach, founder of the Alpínid dynasty. Kenneth I conquered the kingdom of the Picts in 843–850 and began a campaign to seize all of Scotland and assimilate the Picts, for which he was posthumously nicknamed An Ferbasach. He fought the Britons of the Kingdom of Strathclyde and the invading Vikings from Scandinavia. Forteviot became the capital of his kingdom and Kenneth relocated relics, including the Stone of Scone from an abandoned abbey on Iona, to his new domain.

Dál Riata or Dál Riada was a Gaelic kingdom that encompassed the western seaboard of Scotland and north-eastern Ireland, on each side of the North Channel. At its height in the 6th and 7th centuries, it covered what is now Argyll in Scotland and part of County Antrim in Northern Ireland. After a period of expansion, Dál Riata eventually became associated with the Gaelic Kingdom of Alba.
