Kenneth I of Scotland - Detail from a frieze in the Scottish National Portrait Gallery, Queen Street, Edinburgh
Notes: Kenneth I was the first King of the Scots according to the traditional view of Scottish history: a King of the Picts, he united the various tribes. Whether that was the case is unclear; it's equally possible he was a King of the Scots who conquered the Picts, given how quickly Pictish traditions disappeared.
His ancestors were likely the Kings of Dál Riata who can be traced in the Irish and Welsh annals back to the mid-6th century. There is no contemporary evidence to support those regnal lists.
