The Cantabrian Wars (29–19 BC) (Bellum Cantabricum), sometimes also referred to as the Cantabrian and Asturian Wars (Bellum Cantabricum et Asturicum), were the final stage of the two-century long Roman conquest of Hispania, in what today are the provinces of Cantabria, Asturias and León in northwestern Spain.
During the reign of Emperor Augustus, Rome waged a bloody conflict against the Cantabri, the Astures and the Gallaeci still resisting Roman occupation, the last independent Celtic nations of Hispania. These warlike peoples fiercely resisted Roman domination; ten years of war and eight legions with their auxiliary troops – more than 50,000 soldiers in total – were needed to subdue the region.
