Bronze with horse

The Ambiani occupied territory in what is now the Pas-de-Calais region of northern Gaul and were among the tribes Caesar specifically named as contributing forces to the coalition assembled against him during the Gallic Wars. Their bronze coinage circulated during precisely the decades when that military and political pressure was most acute — the Roman campaigns of 58–50 BC disrupted tribal economies across the region, and the survival of local bronze issues into the 40s BC suggests the Ambiani retained some degree of monetary autonomy even after Roman consolidation.
