List of Kings of the Picts

Time you got around to sponsoring a child
This list is based on the Pictish Chronicle, which has survived in a late copy, and did not record the dates the kings reigned. The dates given are based on guesswork and inference from contemporary records.

Drust was the last ruler of the Picts. Kenneth MacAlpin became King of the Scots and Picts in 848. His kingdom became known as Alba.
