The Scots tribe originated from Ireland, from the now-called counties Antrim and Down.

In 500 under King Fergus, the Scots invaded Argyll and established the realm known as Dál Riata (Dalriada) in the Pictish lands known as Caledonian by the Romans. However, the relationship between these two peoples begins earlier: around 300 when the Romans recorded almost 300 frontier attacks by the Picti and the Scotti.

While the Romans represented a common enemy, the Picts and Scots supported each other. However, the departure of the Romans left the two sides to compete with each other for power and territory. Wars between Caledonia and Dalriada were numerous between 300 and 840—the Picts frequently coming out on top; Dalriada often being ruled by the Picts.

In the early 9th century when the Vikings started plundering along the coastline of Caledonia and neighbouring countries, the Pictish kingdom found itself facing enemies on two fronts. After successfully defeating the Scots, a major battle with the Vikings in 839 severely weakened the Picts strength. Caledonia went on to suffer several quick successions of kings.

After the death of the king of Dalriada, Alpin Mac Eochaid, his son Ciniod Mac Alpin, Kenneth I in 843 laid claim to the throne of Caledonia through maternal bloodlines, and thereby united both kingdoms, becoming King of Alba.
