Eastern Iranic-speaking equestrian nomads of the Pontic-Caspian steppe who raided south across the Caucasus into Urartu, Anatolia, and the Neo-Assyrian frontier through the 8th-7th centuries BC; known almost entirely from Neo-Assyrian annals and later Greek accounts, as they left no written records of their own.
Displaced from the Pontic steppe by the incoming Scythians and progressively defeated/dispersed in Anatolia (notably by Lydia and Assyria); last securely attested campaigning around the turn of the 7th-6th centuries BC.
