Cimmerians

Ancient nomadic Iranic people who invaded West Asia in the 8th and 7th centuries BC

The Cimmerians were an ancient Eastern Iranic equestrian nomadic people originating in the Pontic–Caspian steppe, part of whom subsequently migrated into West Asia. Although the Cimmerians were culturally Scythian, they formed an ethnic unit separate from the Scythians proper, to whom the Cimmerians were related and who displaced and replaced the Cimmerians.
