The Iron Age in Northern Britain examines the impact of the Roman expansion northwards, and the native response to the Roman occupation on both sides of the frontiers. It traces the emergence of historically-recorded communities in the post-Roman period and looks at the clash of cultures between Celts and Romans, Picts and Scots. Northern Britain has too often been seen as peripheral to a 'core' located in south-eastern England.
Unlike the Iron Age in southern Britain, the story of which can be conveniently terminated with the Roman conquest, the Iron Age in northern Britain has no such horizon to mark its end. The Roman presence in southern and eastern Scotland was militarily intermittent and left untouched large tracts of Atlantic Scotland for which there is a rich legacy of Iron Age settlement, continuing from the mid-first millennium BC to the period of Norse settlement in the late first millennium AD.
Here D.W. Harding shows that northern Britain was not peripheral in the Iron Age: it simply belonged to an Atlantic European mainstream different from southern England and its immediate continental neighbours.
