Cimmerian

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 were ethnically distinct from the Scythians proper, to whom the Cimmerians were related and who displaced and replaced the Cimmerians.
