To the discussion about the cause of the Scythia fall

For many years causes of the fall of Scythia have been a subject to a great deal of scientific scrutiny. The topic is still debatable. The author has recently published several papers, which justify Sarmatians' involvement in the fall of Scythia in the late 4th and early 3rd centuries BC based on the written and archaeological evidence. Previously, the concept has also been supported by other researchers. These days, however, there are studies in favor of alternative versions claiming Sarmatians' innocence in the events leading to the fall of Scythia. The main ideas of the studies boil down to the statement of no evidence of Sarmatians from the 3rd century BC being found not only in the North Pontic region but also to the east from the Don river. In the light of the statement, they implement the idea that Sarmatians' appearance in the Eastern European steppes dates back to the time not earlier than the 2nd century BC. In the article, the author, given the anthropological and archaeological datasets, confirms the Sarmatians' continuous presence in the Volga-Urals region without any chronological gaps between the 4th and the 1st century BC. The idea of the stage-by-stage settlement of the eastern nomads in the Volga-Don region and the North Pontic region is suggested. In the first stage, since the middle of the 4th century BC, the political situation underwent some destabilization processes due to the appearance of Sarmatians in the Lower Don region. The second stage is characterized by Sarmatians attacking Scythia in the first half of the 3rd century BC. For most of the 3rd century BC, Sarmatians' main habitat was located to the east of the Don river. From there they conducted raids on the territory of the Northern part of the Black Sea region to plunder or collect the tribute. This concept is also supported by linguists' new interpretations of written sources.
