The Cimmerians were an ancient people, who lived in the south of modern-day Russia, at least in the 8th and 7th century BC. Little is known about them, but they were mentioned in the writings of Greek writer Homer, who says that they live in a land of fog and darkness at the borders of the known world. The historian Herodotus gives more details about their history, describing the savagery of their plunder raids and their attack on Lydia, when they occupied for a brief time the Lydian capital of Sardis. The Cimmerians as a distinctive people were almost completely wiped out by the Scythians, who had migrated from Central Asia under pressure from Chinese tribes. Nomad Scythian cavalry tactics completely crushed the agricultural Cimmerian soldiers though it is expected that Scythians had ultimately adopted their Horse-riding skills from the Cimmeri.
The reputation of the Cimmerians for savagery, combined with their mysteriousness, led the fantasy author Robert E. Howard to identify his character Conan the Barbarian as a Cimmerian. Some Celtic peoples traditionally consider themselves as descended from Cimmeri and their ethnicons reflect this belief (e.g. Cwmry & Cumbria)
