The Ordovīcēs (Common Brittonic: *Ordowīces) were one of the Celtic tribes living in Great Britain before the Roman invasion. Their tribal lands were located in present-day North Wales and England, between the Silures to the south and the Deceangli to the north-east. Unlike the latter tribes that appear to have acquiesced to Roman rule with little resistance, the Ordovices fiercely resisted the Romans. They were eventually subjugated by the Roman governor Gnaeus Julius Agricola in the campaign of 77–78CE when the Romans overran their final strongholds on Anglesey.
