The Cimmerians (also Kimmerians; Greek: Kimmerioi, Kimmerioi) were an ancient people, who appeared about 1000 BC  and are mentioned later in 8th century BC in Assyrian records. Probably originating in the Pontic steppe and invading by means of the Caucasus, they are likely to be those who in c. 714 BC assaulted Urartu, a state in north eastern Anatolia subject to the Neo-Assyrian Empire. They were defeated by Assyrian forces under Sargon II in 705 and turned towards Anatolia, conquering Phrygia in 696/5. They reached the height of their power in 652 after taking Sardis, the capital of Lydia; however an invasion of Assyrian controlled Anshan (Persia) was thwarted.
Archaeology
The supposed origin of the Cimmerians north of the Caucasus at the end of the Bronze Age loosely corresponds with the early Koban culture (Northern Caucasus, 12th to 4th centuries BC), but there is no compelling reason to associate this culture with the Cimmerians specifically.  There is a tradition in archaeology of applying Cimmerian to the archaeological record associated with the earliest transmission of Iron Age culture along the Danube to Central and Western Europe, associated with the Cernogorovka (9th to 8th centuries) and Novocerkassk (8th to 7th centuries) between the Danube and the Volga. This association is "controversial", or at best conventional, and is not to be taken as a literal claim that specific artifacts are to be associated with the "Cimmerians" of the Greek or Assyrian record.  The use of the name "Cimmerian" in this context is due to Paul Reinecke, who in 1925 postulated a "North-Thracian-Cimmerian cultural sphere" (nordthrakisch-kimmerischer Kulturkreis) overlapping with the younger Hallstatt culture of the Eastern Alps. The term Thraco-Cimmerian (thrako-kimmerisch) was first introduced by I. Nestor in the 1930s. Nestor intended to suggest that there was a historical migration of Cimmerians into Eastern Europe from the area of the former Srubna culture, perhaps triggered by the Scythian expansion, at the beginning of the European Iron Age. In the 1980s and 1990s, more systematic studies[by whom?] of the artifacts revealed a more gradual development over the period covering the 9th to 7th centuries, so that the term "Thraco-Cimmerian" is now rather used by convention and does not necessarily imply a direct connection with either the Thracians or the Cimmerians.
