Irish annals (the Annals of Ulster, Annals of Innisfallen) refer to some kings as king of Fortriu or king of Alba. The kings listed are thought to represent overkings of the Picts, at least from the time of Bridei son of Maelchon onwards. In addition to these overkings, many less powerful subject kings existed, of whom only a very few are known from the historical record.
