The 11th and 12th centuries were a transformative era for Europe and the wider world, marked by the decline of the Viking age and the rise of Christian monarchies. As the new millennium dawned, powerful Viking rulers, many still pagan, commanded vast armadas and claimed entire kingdoms. Within a generation, however, most Scandinavian rulers had converted to Christianity, and their traditional way of life, including the longships they sailed in, began to fade into obsolescence. This documentary explores the fascinating history of the late Viking world on the cusp of the medieval era, charting the evolution of the Viking longship and the shifting power dynamics of the time.
