Viking forces under Halfdan Ragnarsson, previously part of the Great Heathen Army that had ravaged Anglo-Saxon England, relocated to a base on the river Tyne and began raiding Pictish lands and those of the Strathclyde Britons, bringing them into direct conflict with King Constantine I.
In 875, at Dollar in Scotland, Viking invaders under Halfdan Ragnarsson met and defeated the Pictish forces of King Constantine I. The battle resulted in a clear Viking victory, forcing Constantine to retreat northward into the highland region of Atholl.
Following the victory, Vikings occupied the east-central lowlands of Scotland for roughly a year before settling in Northumbria. Constantine I died fighting the Vikings again in 876. The cumulative devastation of 875–878 effectively ended Pictish presence in the historical record.
