The Battle

History & Significance

839 was a catastrophic year for the Picts. The Annals of Ulster record that the Vikings destroyed a Pictish army and killed King Eóganán mac Óengusa and his brother — possibly in the same campaign that ravaged the Forth coast. The destruction of Pictish royal leadership in a single year opened the door for Kenneth mac Alpin to impose his dynasty on both Picts and Scots, merging them into the Kingdom of Alba.
